Introduction
WTI’s APS-8M Asynchronous Port Switch allows reliable, highspeed connections between PCs, modems, and other devices
using dissimilar baud rates, parity, and flow control. The
APS-8M supports communication at speeds up to 115.2 Kbps,
and features full RTS/CTS hardware handshaking and a 33.6K
internal modem. Lightening-swift data throughput and full flow
control make the APS-8M the perfect data switch for today’s
high speed communications applications.
Versatile Connectivity
Up to seven different devices can be connected to the APS-8M
without the need to select a common baud rate or parity. Each
port can be individually configured for specific baud rates,
parity, handshaking, and various other parameters and options.
Easy Set-Up and Operation
Configuration of the APS-8M is simple. A menuing system is
used to select communications parameters, and enable or disable
options. The APS-8M can easily adapt to the requirements of
almost any data communications application.
Limited Command Access
The APS-8M is ideal for situations that require limited access to
important commands. Two security levels allow each port to
function as a Supervisor Port or User Port, depending on the
password entered at login. Supervisor Ports are allowed to
change configuration, display status, and connect to any other
port; User Ports are only allowed to connect to the ports provided
by their password. Each individual port can be assigned its own
unique, user-defined password, up to sixteen characters long.
Password Protected Connection and Command Access
The convenient password feature provides restricted access to
command functions, and also restricts unauthorized connection to
specific ports. Each individual port can be assigned its own
unique, user-defined password, up to sixteen characters long.

APS-8M User’s Guide
Convenient Internal Modem
The APS-8M features a 56K MutliTech format Internal modem;
this simplifies the procedure for setting up the unit for out-ofband access to command features.
Non-Volatile Memory
If power to the unit is lost or interrupted, the APS-8M’s nonvolatile memory will retain user-defined parameters and port
connections.
Modem Communication
The APS-8M can be controlled by a local PC that communicates
with the unit via cable, or controlled remotely via external
modem. ProComm ® (or another communications program) is
used to send commands to connect ports or display status.
Configuration Backup
Once you have configured the APS-8M to fit your application,
parameters and options can be saved to an ASCII text file on
your PC. This allows you to quickly restore user-selected
parameters if the unit configuration is accidentally altered or
deleted. Saved parameters can also be uploaded to other
APS-8M units. This allows rapid set-up when several units will
be configured with identical or similar parameters.

Connecting Power to the APS Unit
The APS is available in both AC and DC powered versions.
When connecting AC or DC power to the APS, proceed as
follows:
CAUTION: This device should only be operated
with the type of power source indicated on the
instrument nameplate. If you are not sure of the
type of power service available, please contact
your local power company.
4.1.1.
AC Powered Units
The Voltage Selector Switch on the instrument back panel is used
to set the unit for 115V or 230V AC power. Plug the supplied
power cable into the receptacle on the APS back panel and then
connect the power cable to a grounded AC outlet.
4.1.2.
DC Powered Units
The DC terminal block features two bus inputs as shown in

APS-8M User’s Guide
4.2.
Configure SetUp Switches
The SetUp Switches are used to select default settings for the
APS RS232 ports. The SetUp Switches are located on the
APS-8M back panel, as shown in Figure 2.1.
When the APS-8M is shipped from the factory, the SetUp
Switches are configured for 9600 baud, 8 Bits-No Parity,
RTS/CTS handshaking, verbose command response, and
command echo on (all switches ON). These settings are
compatible with most applications. If the default settings are not
compatible with your application, change the switch settings
as follows.
Notes:
· The SetUp Switches should be configured to match
the parameters your control device will use when
communicating with the APS-8M. This will ensure
access to command functions, even if the unit is
reset to default parameters.
· If the SetUp Switch configuration is changed, new
parameters will not take effect until the unit is
reinitialized as described in Section 4.3.
· Operating parameters (baud rate, parity, etc.) can
be selected for each port using the /P command as
described in Section 5.5. The /P command can
select different parameters for each APS port.
· When the APS is initialized, parameters will return
to settings specified by the SetUp Switches.

Hardware Installation
4.2.1.
Default Baud Rate (Sw1, Sw2, Sw3)
SetUp Switches one through three select the default baud rate for
RS232 Ports One through Seven. The default baud rate must
match the rate your control device will use when communicating
with the APS-8M.
Notes:
· If the control device will communicate via an
external modem connected to one of the RS232
Ports, select a default baud rate that is compatible
with the external modem.
· The /P command can also be used to select a
different operating baud rate for each port.
· SetUp Switches one through three do not set the
default baud rate for Port 8 (the Internal Modem
Port). The default baud rate for Port 8 is 9600 bps.
The operating baud rate for Port 8 can also be set
via the /P command.

Default Handshake (Sw4, Sw5)
SetUp Switches four and five select the default handshake format
for RS232 Ports One through Seven. The default handshake
format must match the format your control device will use when
communicating with the APS. SetUp Switches four and five can
select RTS/CTS (hardware), XON/XOFF, Both or None.
Notes:
· If the control device will communicate with the
APS-8M via an external modem connected to one
of the RS232 ports, select a default handshaking
format that is compatible with the external modem.
· The /P command can also be used to select a
different handshake format for each port.
· Setup Switches Four and Five do not select the
default handshake format for Port 8 (the Internal
Modem Port). The default handshake format for
Port 8 is RTS/CTS. The operating handshake
format for Port 8 can also be set via the /P
command.

connectors, configured as DTE Ports, and are similar to a
standard serial port on a PC.
1. Access the APS-8M Command Mode.
2. Determine which RS232 port will be used for connection to
the new device (e.g. Port 3).
3. Check Buffer: Type /S [Enter] to display the Port Status
Screen. Check the "Buffer Count" column, which lists the
amount of data stored in the buffer for each port.
a) If the Port Status Screen shows data stored in the buffer
for the desired port, type /E xx [Enter] to clear the
buffer (where xx is the desired port number).
b) Note that cleared data cannot be recovered.
4. Use an appropriate DB9 cable to connect the RS232 serial
port on the device to the selected DB9 port on the APS.
a) External Modems and other DCE Devices: Use a
standard serial modem cable.
b) PCs and other DTE Devices: Use a standard null
modem cable.
5. Select communication parameters for the port as described
in Section 5.

Access to the APS Command Mode
When the APS-8M Command Mode is active, commands can be
invoked to select parameters, and connect or disconnect ports.
Note:
· Command Mode cannot be accessed from a Buffer
Mode Port, Passive Mode Port, or any port that is
currently connected to another APS-8M port.
· Supervisor Level Commands cannot be accessed at
any APS-8M port where the Supervisor Level has
been disabled.
1. Start your communications program (e.g. HyperTerminal or
ProComm ® ). Make certain the APS and the communications program are set for the same parameters (e.g. baud
rate, parity, etc.).
2. Access the Command Mode.
a) Local Access: To access the command mode from a
local PC that is connected to the APS via cable,
press [Enter].
i.
There must be no other characters preceding
[Enter]. If you have already hit other keys, press
[Enter] twice.
ii. If the Supervisor Password has been defined, the
password prompt will be displayed. Key in your
Supervisor or Port password and press [Enter]. The
"APS>" prompt will appear.
b) Modem Access: To access the command mode via
modem, proceed as follows:
i.
Dial the number for the APS-8M's internal modem,
or (if present) for an external modem connected to
one of the APS-8M's RS232 ports.
ii. If you have defined the Supervisor Password, a
prompt will be displayed. Key in your Supervisor
or Port password and press [Enter]. If the
Supervisor Password has not been defined, just
press [Enter]. The "APS>" prompt will appear.

System SetUp Ports
Ports 1 and 2 are designated as System SetUp Ports, and will
therefore always permit password protected access to Supervisor
Level command functions, even when the unit is reinitialized to
default parameters.
In order to ensure that access to command functions is always
available, Ports 1 and 2 cannot be configured as Buffer Mode or
Passive Mode Ports (Buffer and Passive Mode Ports are not able
to access the Command Mode.) In addition, Ports 1 and 2 always
permit password protected access to Supervisor Level
commands; the Supervisor Mode cannot be disabled at these
two ports.
5.3.
Password Functions
The APS features two different types of passwords; the
Supervisor Password and the Port (User) Passwords. The
Supervisor Password allows system administrators to invoke unit
configuration commands, and the Port Passwords allow users to
access specific ports in order to create connections between
permitted ports or view port configuration parameters.
5.3.1.
The Supervisor Password
The Supervisor Password allows access to higher level APS-8M
configuration commands, which administrators can employ to
select communication parameters, assign port access rights, and
perform other system management tasks.
After the Supervisor Password has been defined (via the System
Parameters menu), the APS-8M will display a password prompt
whenever you attempt to access the command mode. If the
correct Supervisor Password is entered, the APS command mode
then starts up in Supervisor Mode. Supervisor Level commands
are summarized in Section 11.3 of this User’s Guide.
5-2
Configuration
Notes:
· If the Supervisor Password is not defined, then
Supervisor Level commands will be available to all
ports, and port access and configuration functions
will not be password protected.
· If you wish to restrict user ports from changing
APS-8M configuration parameters or connecting to
restricted ports, the Supervisor Password must be
defined.
· When the Supervisor Password is defined, the
APS-8M will display a password prompt when you
attempt to access the command mode. Any RS232
port that has not been assigned a Port Password,
can then only be accessed using the Supervisor
Password.
· When defining a Supervisor Password, it is
strongly recommended that you record the
password for future use. If you forget or lose your
Supervisor Password, you will not be able to
access Supervisor Level Commands. In this case,
the only way to access the Supervisor Mode, is to
reinitialize the APS-8M to default values as
described in Section 4.2.
Normally, the Supervisor Password can be entered at any port in
order to gain access to Supervisor Level commands. Note that if
you wish to completely deny a port’s access to Supervisor Mode
(even with the Supervisor Password), the Port Parameters menus
(/P) can be used to disable the Supervisor Mode at ports 3
through 8. The Supervisor Mode cannot be disabled at System
SetUp Ports 1 and 2.
Note that if the unit is reset to default parameters, all ports will
revert to the default state, where Supervisor Level commands are
available to all ports, without password protection.
5-3
APS-8M User’s Guide
5.3.2.
The Port Passwords
The Port Passwords (or User Passwords) allow system
administrators to restrict access to a specific group of ports.
When the APS-8M command mode is accessed with a Port
Password, users may only connect to the RS232 Ports to which
they have been granted access, and review configuration
parameters for those ports. Port Passwords do not grant access
to APS-8M configuration commands.
The configuration menus (/P) for each RS232 port allow a Port
Password to be assigned to each individual port. In order to
allow a Port Password to grant access to a group of APS-8M
ports, the same Port Password is assigned to each port in the
group.
For example, if the Port Password “test” is assigned to ports 3, 4,
and 5, then when “test” is entered at the Password Prompt, the
user will only be able to connect to ports 3, 4, and 5, and will
only be able to view parameters for ports 3, 4, and 5.
If desired, all APS-8M ports can function as both a Supervisor
Port and a User Port, depending on which password is entered at
the login prompt. However, if you wish to prevent a port from
being able to access the Supervisor Mode at all (even with the
Supervisor Password), the Supervisor Mode can be disabled at
the RS232 Ports using the Port Configuration menus as described
in Section 5.5. Note however, that the Supervisor Mode cannot
be disabled at Ports 1 and 2; these ports are designated as SetUp
Ports, and are always allowed password protected access to
Supervisor Level commands.
Note: When Port Passwords are defined, the
APS-8M will not allow you to select a Port Password
that has already been used as the Supervisor
Password.

5.4.
Defining the Site ID and Supervisor
Password
Before configuring individual ports, the Site ID and Supervisor
Password should be defined. The Site ID indicates the location
or name of the APS-8M; the Supervisor Password restricts access
to sensitive command functions. The Site ID and Supervisor
Password are defined via the System Parameters menu (/F).
Notes:
· The Site ID cannot include double quotes.
· The Supervisor Password cannot include an
asterisk, forward slash, spaces, or double quotes.
· Both the Site ID and Supervisor Password will be
cleared if the APS is initialized to default settings.
· The APS will not allow you to select a Supervisor
Password that is the same as an existing Port
Password.
· The System Parameters Menu is only available in
Supervisor Mode.
1. Access the Command Mode. Type /F [Enter] to display
the System Parameters Menu.
2. Site ID Message: (Up to 32 chars.; Default = undefined)
Type 1 and press [Enter], a prompt will appear. Key in
the desired text and press [Enter] . The Site ID will be
listed on the Port Status and Port Diagnostic Screens.
3. Supervisor Password: (Up to 16 characters; Default =
undefined) Type 2 and press [Enter], a prompt will
appear. Key in the desired password, then press [Enter].
The APS-8M will prompt you to re-key the password to
confirm spelling and capitalization. Key in the password a
second time, and then press [Enter].
Notes:
· The Supervisor Password is case sensitive. Make
certain to note the exact password entered,
including the case of each letter.
· Make certain to write down your Supervisor
Password. If the password is lost or forgotten, you
will not be able to access Supervisor Level
commands unless you initialize the unit and clear
all parameters as described in Section 4.3.

Port Modes
The APS offers four different port operation modes; Any-to-Any
Mode, Passive Mode, Buffer Mode, and Modem Mode. The Port
Modes function as follows:
· Any-to-Any Mode: Allows communication between
connected ports. Any-to-Any Mode Ports can be connected
to other Any-to-Any Mode, Passive Mode, Buffer Mode, or
Modem Mode Ports by accessing Command Mode and
invoking the /C command (see Section 8.1.1). The
Any-to-Any Mode is available to all APS ports, except
Port 8 (the External Modem Port).
· Passive Mode: Allows communication between connected
ports, but does not allow access to Command Mode. Passive
Mode Ports can be connected by accessing Command Mode
from a free Any-to-Any or Modem Mode port and invoking
the /C command (see Section 8.1.1). The Passive Mode is
not available to Ports 1, 2, or 8.
· Buffer Mode: Allows collection and storage of data
received from connected devices. Collected data can be
retrieved by accessing Command Mode from a free Any-toAny or Modem Mode Port, and issuing the Connect (/C)
Command. Note that the Buffer Mode also allows passthrough communication with the connected device. The
Buffer Mode is not available to Ports 1, 2, or 8.
· Modem Mode: A port configured for the Modem Mode can
perform all functions normally available in Any-to-Any
Mode, but the Modem Mode also allows definition of a
Hang-Up String, Reset String, and Initialization String. Any
APS RS232 port can be configured for the Modem Mode,
and Port 8 (the External Modem port) is always configured
for Modem Mode.
For more information on Port Modes, please refer to Section 8.

complete listing of all available AT commands and
S-Registers, please visit the User's Guide Archive
at the WTI web site:
http://www.wti.com/guides/guidarch.htm
8. Supervisor Mode: Permits or denies access to Supervisor
Mode. When enabled (Permit), and the valid Supervisor
Password is entered, the port will allow access to
Supervisor Level commands. When disabled (Deny), the
port may not enter Supervisor Mode, even when the
Supervisor Password is entered. (Default = Permit).
Note: The Supervisor Mode cannot be disabled at
Ports 1 or 2.
9. Logoff Character: Defines the Logoff Character for this
port. The Logoff Character determines the command(s) or
character(s) that must be issued at this port in order to
disconnect from a second port (Resident Disconnect).
(Default = ^X ([Ctrl] plus [X])).
Note: When redefining the Logoff Character, make
certain to select a character that does not normally
occur in your data. This will prevent the unit from
accidentally disconnecting ports in the middle of a
data transfer. For example, if the Logoff Character is
defined as "s", then the ports will disconnect
whenever the letter "s" is detected.

APS-8M User’s Guide
10. Sequence Disconnect: Enables/Disables and configures
the Resident Disconnect command. This prompt offers the
option to either disable the Sequence Disconnect, or select
a one character format or a three character format.
(Default = One Characters). Note the following:
· When a Resident Connection is initiated, the APS will
send a message which lists the connected ports, and
displays the one character or three character command
that will be required in order to disconnect.
· The One Character Disconnect sequence is intended for
situations where the destination port will not receive the
disconnect command. When the Three Character format
is selected, the disconnect sequence will pass through to
the destination port prior to breaking the connection.
· When the One Character format is selected, resident
connections are terminated by entering the selected
Logoff Character only. There is no need to press [Enter]
before and after the Logoff Character when the One
Character format is selected.
· When the Three Character format is selected, the
Resident Disconnect Sequence will use the format
"[Enter]LLL[Enter]", where L is the selected Logoff
Character.
11. Timeout Disconnect: Enables and selects the Timeout
Period for this port. If enabled, and the port does not
receive or transmit data for the specified Timeout Period,
the port will disconnect. In Any-to-Any Mode, Passive
Mode, or Buffer Mode, the default setting for this item is
“OFF”. When the port is set for Modem Mode, the default
setting for this item is 15 minutes.
Notes:
· The Timeout Disconnect is also applied to nonconnected ports that are left in Command Mode. If
no additional data activity is detected, an
unconnected port will exit from command mode
when the Timeout Disconnect value expires.
· When connected ports time out and are
disconnected, both ports will also exit from
Command Mode.

Quiet Mode (No Response).
(Default = Verbose).
13. Command Echo: Enables or Disables the command echo
for this port. (Default = On).
14. Accept Break: Determines whether the port will accept
breaks received from the attached device, and pass them
along to a connected port. When enabled, breaks received
at this port will be passed to any port that this port is
connected to, and sent along to the device connected to the
other port. When disabled, breaks will be refused at this
port, and hence, not sent to the other port. (Default = Yes)
5.6.
Copying Parameters to All Ports
The /CP command (Copy Port Parameters) provides a convenient
means for selecting similar parameters for all APS RS-232 ports.
When the /CP command is invoked, the unit will display a menu
which allows you to select port communication parameters, then
copy them to all APS RS-232 ports. The Copy Port Parameters
menu can be used to set all parameters for all RS-232 Ports, or
define only a select group of parameters and then copy them to
all ports.
Notes:
· The /CP command is only available in Supervisor
Mode.
· The Copy Port Parameters Menu will not display
the Port Password. This field will read either
“undefined” or “defined”, depending upon whether
or not the Port Password has been specified.
· The /CP command cannot be used to set Ports 1
and 2 to Passive Mode or Buffer Mode
(Port Mode, Item 7.)
· The /CP command cannot be used to disable the

The Internal Modem
This section lists the most commonly used AT commands for the
APS-8M's internal Multi-Tech modem, and briefly describes the
procedure for communicating with the internal modem. Please
note that although APS-8M Port 8 is the internal modem port,
any APS-8M port can also be configured for connection to an
external modem.
6.1.
Communicating with the Internal
Modem
To communicate with the APS-8M's internal modem, proceed
as follows:
1. Access the APS command mode as described in
Section 5.1.
Notes:
· If you log on to the APS-8M using a Port Password
(rather than the Supervisor Password), you will
only be able to connect to Port 8 if your password
allows access to that port. The Supervisor
Password always allows access to Port 8.
· To access the internal modem's command mode
from a remote location, you must first dial into an
external modem installed at one of the other RS232
ports, and then proceed as described below. The
internal modem's command mode cannot be
accessed via a remote connection to the internal
modem.
2. When the APS> command prompt appears, type /C 8 and

The Status Screens
The APS-8M Status Screens display the connection status and
communication parameters for the APS RS-232 ports. There are
three different types of status screens; The Port Status Screen
(/S), the Port Diagnostics Screen (/SD), and the Port Parameters
Screens (/W).
7.1.
The Port Status Screen (/S)
The Port Status Screen lists the general status of the APS’s
RS-232 ports. To display the Port Status Screen, access the
command mode and type /S [Enter], the screen will appear as
shown in Figure 7.1.
Although both Supervisors and Users can display the Port Status
Screen, the screen will appear slightly different, depending upon
whether the command mode was accessed with the Supervisor
Password or a Port Password. When a Port Password (User
Mode) is entered at login, the Port Status Screen will only
display the status of those ports that share the same Port
Password that was entered at login.
When the Supervisor Mode is active, the Port Status Screen
offers the option to either display or suppress Port Passwords.
Normally, when the /S command is invoked, the Password
column will read either “defined” or “undefined”, depending
upon whether or not the password for each port has been
specified. To display the Port Status Screen with Port Passwords
included, type /SP and then press [Enter]. Note that the /SP
command option is not available in User Mode.

The Port Diagnostics Screen (/SD)
The Port Diagnostics Screen provides more detailed information
about each port, including the port name and communication
parameters. To display the Port Diagnostics Screen, access the
command mode and type /SD [Enter], the screen will appear as
shown in Figure 7.2.
Like the Port Status Screen, the Port Diagnostics Screen is also
available to both Supervisors and Users, and will look slightly
different, depending upon whether the command mode was
accessed with the Supervisor Password or a Port Password
(User Mode).
In User Mode, the Port Diagnostics Screen will display only the
status of those ports that share the same Port Password that was
entered at login. Ports that are protected by other passwords will
not be displayed.
7-3
APS-8M User’s Guide
As shown in Figure 7.2, the Port Diagnostics Screen lists the
following items:
· Port: The Port Number. Note that if this column contains a
plus sign (+), this indicates that the port will be allowed to
access the Supervisor Mode if the appropriate Supervisor
Password is entered at login.
· Name: The user-defined name for each port.
· Status: The connect status for each port. When the port is
connected, this column will list the number of the other port
that is connected to this port. Note that if this column
contains an asterisk, this indicates that the port has accessed
the Command Mode.
· Baud: The baud rate selected for each port.
· COM: The Data Bits, Parity, and Stop Bits selected for
each port. For example, “8N1” indicates Eight data bits, No
parity, and One stop bit.
· HS: The handshaking (flow control) mode for each port.
· Mode: The user-selected Port Mode. This column will read
Any (Any-to-Any), Modem, Passive, or Buffer, depending
on the configuration selected for each port.
· BUF: Lists the amount of data (in bytes) currently stored in
the buffer for this port.
· CTS: The High/Low status of the CTS line at the RS232
interface.

The Port Parameters Screens (/W)
The /W command displays more detailed information about an
individual APS port. Rather than listing connection information
for all ports like the Port Status Screens, the Port Parameters
screen lists all defined parameters for a specific port.
The /W command is available in both Supervisor Mode and User
Mode. Note however, that when you log in with a Port (User)
password, the APS will only display information regarding your
resident port.
If the Supervisor Mode is active, the Port Parameters Screens
offer the option to either display or suppress Port Passwords.
Normally, when /W is invoked, the Password field will read
either “defined” or “undefined”, depending upon whether or not
the port’s password has been specified. To display the Port
Parameters Screen with the Port Password, type /WP, followed
by the desired port number, and then press [Enter]. Note that
the /WP command option is not available in User Mode.

8.
Operation
8.1.
Any-to-Any Mode
Any-to-Any Mode Ports can be connected to other Any-to-Any,
Passive, Buffer, or Modem Mode Ports by accessing Command
Mode and issuing the /C Command. All ports can be configured
for the Any-to-Any Mode.
8.1.1.
Port Connection and Disconnection
The APS provides communication between devices without the
requirement that both devices use the same communication
parameters. This allows you to connect devices that use
dissimilar baud rates, parity, handshake, and etc. The APS
converts data rates and other parameters, eliminating the need to
select common parameters for all connected devices.
8.1.1.1.
Connecting Ports
Two different types of connections can be made between APS
ports; Resident Connections and Third Party Connections.
· Resident Connections: Your resident port issues a /C
command to connect to a second port. For example, Port 4
issues the /C command to connect to Port 5.
· Third Party Connections: (Supervisor Mode Only) Your
resident port issues a /C command to create a connection
between two other ports. For example, Port 1 is your
resident port, and Port 1 issues a command to connect Port 2
to Port 3.
Notes:
· Third Party Connections can only be initiated from
a port with Supervisor Level command capability.
· If a port has accessed Command Mode using the
Port Password (User Mode), then that port will
only be able to connect to other ports that share the
same port password.
8-1
APS-8M User’s Guide
To Connect ports, proceed as follows:
1. Access the Command Mode as described in Section 5.1. If
the Password Prompt is displayed, enter your Supervisor
Password or Port Password.
2. Invoke the /C command to connect the desired ports.
a) Resident Connect: To connect your resident port to
another port, type /C xx [Enter]. Where xx is the
number or name of the port you want to connect. The
APS will display the numbers of the connected ports,
along with the command sequence that will be required
in order to disconnect the two ports.
Example: To connect your resident port to Port 8, type
/C 8 [Enter].
b) Third Party Connect: (Supervisor Mode Only) To
connect any two ports (other than your resident port),
type /C xx XX [Enter]. Where xx and XX are two
port names or numbers. The APS will display the
numbers of the two connected ports.
Example: To connect Port 5 to Port 6, invoke the
following command at a port with Supervisor Level
command capability: /C 5 6 [Enter].
When the /C command specifies the port name, it is only
necessary to enter enough letters to differentiate the desired port
from other ports. Type an asterisk (*) to represent the remaining
characters in the port name. For example, to connect your
resident port to a port named "SALES", the connect command
can be invoked as /C S*, providing no other port names begin
with the letter "S".
8-2
Operation
8.1.1.2.
Disconnecting Ports
There are three different methods for disconnecting ports, the
Resident Disconnect, the Third Party Disconnect, and the No
Activity Timeout. Providing the Timeout feature is enabled, a
No Activity Timeout will disconnect resident ports or
third party ports.
Note: When Any-to-Any Mode, Buffer Mode, or
Passive Mode are selected, Option 74 in the Port
Parameters Menu determines how the DTR signal
will react when the port disconnects. The DTR
signal can either be held low, held high, or pulsed
and then held high.
1. Resident Disconnect: Disconnects your resident port from
another port. For example, if you are communicating via
Port 3, and Port 3 is connected to Port 4, a Resident
Disconnect would be used to disassociate the two ports.
The APS offers two different Resident Disconnect
command formats; the One Character Format and the Three
Character Format (for more information, please refer to
Section 5.5.3.):
a) One Character (Default): When the One Character
Disconnect Sequence is selected, simply enter the
selected Logoff Character once (Default = ^X ([Ctrl]
plus [X])). Note that it is not necessary to enter a
carriage return before or after the Logoff Character.
b) Three Characters: Uses the format
“[Enter]LLL[Enter]”, where L is the selected Logoff
Character. For example, if the Logoff Character is
defined as "+", then the three character disconnect
sequence would be [Enter]+++[Enter].
c) If the default Resident Disconnect Sequence is not
compatible with your application, both the command
format and Logoff Character can be redefined via the
Port Configuration menus, as described in Section 5.5.
8-3
APS-8M User’s Guide
2. Third Party Disconnect: (Supervisor Mode Only) The /D
command is issued from your resident port to disconnect
two third party ports. For example, if your Resident Port is
Port 1, a Third Party Disconnect would be used to
disconnect Port 3 from Port 4.
a) The /D command uses the format: /D xx XX
[Enter], where xx and XX are the numbers of the ports
that you wish to disconnect.
b) The /D (Disconnect) command can only be invoked by
a port with access to Supervisor Level commands.
c) The /D command can specify both connected ports, or
either of the two ports. For example, if Port 1 is your
resident port, any of the following commands can be
used to disconnect Port 3 from Port 4:
/D 3 4 [Enter]
or
/D 3 [Enter]
or
/D 4 [Enter]
3. No Activity Timeout: Providing the Timeout feature is
enabled at either connected port, the No Activity Timeout
can disconnect Resident Ports, or Third Party Ports.
a) RS232 Ports: To configure the Timeout Feature for the
RS232 Ports, invoke the /P command to display the
Port Configuration Menu for the desired port as
described in Section 5.5.3. Option 11 enables and
defines the Timeout Feature.
b) When the Timeout Feature is enabled, the port will
automatically disconnect if no data is received for the
defined Timeout Period.
Notes:
· When connected ports time out, both ports will exit
command mode after disconnecting.
· When an unconnected port is left in Command
Mode and no additional data activity is detected,
the port will automatically exit Command Mode
when its defined timeout value elapses.
8-4
Operation
8.1.2.
Defining Hunt Groups
A Hunt Group creates a situation where the APS will scan a
group of ports and connect to the first available port in the
group. Hunt Groups are created by assigning identical or similar
names to two or more ports. Hunt Groups can be defined using
Any-to-Any, Passive, Buffer, or Modem Mode Ports.
1. Access the Command Mode. If the password prompt is
displayed, enter the Supervisor Password.
2. Invoke the /P command to access the Port Configuration
Menu for the desired Port(s) as described in Section 5.5.3.
For example, to configure Port 4, type /P 4 [Enter].
3. From the Port Configuration Menu, select item 1 to define
the Port Name.
4. Repeat steps 2 and 3 above to assign identical names to the
other ports in the Hunt Group. For example, a series of
ports in a group could all be named "SERVER".
5. To connect to the next available port in the hunt group,
invoke the /C command using the port name to specify the
desired group. For example, /C SERVER [Enter].
6. Your port will be connected to the first available port in the
group. If all ports are presently connected, the APS will
respond with the "BUSY" message.
7. It is only necessary to enter enough letters of the port name
to differentiate the Hunt Group ports from other ports.
Type an asterisk (*) to represent the remaining characters
in the port name. For example, to connect your resident
port to the first available port in a group of ports named
"SALES1", "SALES2", and "SALES3", the connect
command can be invoked as /C S* [Enter], providing no
other port names begin with the letter "S".
8-5
APS-8M User’s Guide
Hunt Group port names must be unique. Otherwise, ports with
similar names will also be included in the Hunt Group.
Hunt Group Example 1:
1. Ports 1 and 2 are configured as Modem Mode ports, and
external modems are installed at both ports. Port 1 is
named "MODEM1" and Port 2 is named "MODEM2".
2. Your resident port is Port 4. To connect to the first
available external Modem, access the Command Mode and
type /C MODEM* [Enter].
Hunt Group Example 2:
1. Ports 3, 4, and 5 are Any-to-Any Mode ports. All three
ports are named "SERVER".
2. Your resident port is Port 1, and you want to connect Port 2
to the first available server, access the Command Mode and
type /C 2 SERVER [Enter].
8.2.
Passive Mode
Passive Mode Ports function the same as Any-to-Any Mode
Ports, but do not allow access to Command Mode. A Passive
Mode Port can communicate with other ports, but cannot enter
Command Mode, and therefore cannot invoke commands to
redefine port parameters, display status, and etc.
Passive Mode Ports can be connected by accessing the Command
Mode from a free Any-to-Any Mode or Modem Mode Port, and
invoking the Third Party Connect or Resident Connect Command
as described in Section 8.1.1. Passive Mode ports will not buffer
data, except during baud rate conversion.
Notes:
· A Passive Mode Port is not allowed to access the
Command Mode.
· In order to ensure supervisor access to important
command functions, the Passive Mode is not
available to Ports 1 and 2 (SetUp Ports).
· Port 8 (Internal Modem Port) cannot be configured
as a Passive Mode Port.
8-6
Operation
8.3.
Buffer Mode
Ports configured as Buffer Mode ports will collect data from the
connected device and store it in the APS's statically allocated
memory. Each APS port features a fixed length, fixed position
data buffer.
The Buffer Mode allows collection of data from various devices
without the requirement that all devices use the same
communication parameters (e.g. baud rate, parity, etc.).
Notes:
· Buffer Mode Ports cannot access the Command
Mode.
· In order to ensure supervisor access to important
command functions, the Buffer Mode is not
available to Ports 1 and 2 (SetUp Ports).
· Port 8 (Internal Modem Port) cannot be configured
as a Buffer Mode Port.
8.3.1.
Reading Data from Buffer Mode
Ports
To retrieve data from Buffer Mode Ports, you must first
determine which port buffers contain data. To check port buffers
for stored data, access the Command Mode and type /S [Enter]
to display the Port Status Screen.
To retrieve data from buffer memory, go to a free Any-to-Any or
Modem Mode Port, access the Command Mode (Supervisor
Level), and issue the /C command using the following format:
/C xx [Enter]
Where xx is the number or name of the port buffer to be read.
8-7
APS-8M User’s Guide
If the port's buffer is empty, the APS will send a message which
reads "Connected xx, Buffer Empty"; where "xx" is the port
number. If the buffer contains data, the APS will display a
prompt that offers four options:
· Next Screen: To scroll through data one screen at a time,
press the [Space] bar. Each time the space bar is pressed,
the next full screen of data will be sent.
· Scroll All: To send all data without pausing, press [1].
· Skip/Connect: To connect to the buffer port without
sending stored data, press [2].
· Erase/Connect: To connect to the buffer port and erase
stored data, press [3]. Note that buffered data will be erased
immediately and will not be sent.
Note: All four of these options also allow passthrough communication with the device connected to
the Buffer Mode port.
To clear data from the buffer, use the Erase/Connect option, or
go to a free Any-to-Any or Modem Mode Port with Supervisor
Level command capability, and issue the /E (Erase Buffer)
command using the following format:
/E xx [Enter]
Where xx is the number or name of the port buffer to be cleared.
8.3.2.
Port Buffers
The Status Screen lists the amount of Buffer Memory currently
used by each port. The APS uses buffer memory in two different
ways, depending on the user-selected port mode.
· Any-to-Any, Passive, and Modem Mode Ports: When two
ports are communicating at dissimilar baud rates, the buffer
memory prevents data overflow at the slower port.
· Buffer Mode Ports: Stores data received from connected
devices. The user issues a connect command (/C) from an
Any-to-Any Mode or Modem Mode port to retrieve data.
If the Status Screen indicates an accumulation of data, the /E
(Erase Buffer) command can be invoked to clear the buffer.
8-8
Operation
8.4.
Modem Mode
In addition to allowing data transfer, the Modem Mode also
provides additional functions specifically related to modem
communication. A Modem Mode Port can perform all functions
normally available in Any-to-Any Mode. The Modem Mode is
available to all APS RS232 ports. In addition to allowing
configuration of the APS-8M's internal modem, the Modem
Mode also simplifies the process of connecting an external
modem to Ports one through seven.
Note: Port 8 (the internal modem port) is always
configured for the modem mode. Port 8 cannot be
configured as an Any-to-Any Mode, Buffer Mode or
Passive Mode port.
When the Modem Mode is selected, the port configuration menu
(command /P) will display three additional prompts, which allow
the user to re-define the modem reset string, initialization string,
and hang-up string. When the Modem Mode is selected for a
port with Supervisor Level command access, the Supervisor
Password should be defined. This will discourage unauthorized
access to higher command functions.
When a call is received, the unit will prompt the caller to enter a
password. The APS allows three attempts to enter a valid
password. If the correct password is not entered in three
attempts, or if the user does not respond to the password prompt
within 30 seconds, the modem will disconnect. The password
can be defined and enabled by invoking the /P command as
described in Section 5.5.3.
Notes:
· When a Modem Mode Port exits Command Mode,
or the DCD line is lost while the Command Mode
is active, the APS will pulse the DTR line to the
modem. The unit will then send the user-defined
modem command strings to make certain the
modem is properly disconnected and reinitialized.
· All APS-8M RS232 ports can use both the unit's
internal modem and external modem(s) installed at
another RS232 port, providing that the port
password allows access to the desired modem port.
To call out, invoke the /C command to connect to
the port, and then access the modem as you
normally would.

Saving and Restoring
Configuration Parameters
After the APS-8M has been properly configured, parameters can
be downloaded and saved as an ASCII text file. Later, if the
configuration is accidentally altered, the file with the saved
parameters can be uploaded to automatically reconfigure the unit
without the need to manually assign each parameter.
Saved parameters can also be uploaded to other APS-8M units.
This allows rapid set-up when several units will be configured
with the same parameters.
The “Save Parameters” procedure can be performed from any
communications program (e.g. HyperTerminal, ProComm,
Crosstalk, etc.), that allows downloading of ASCII files.
9.1.
Sending Parameters to a File
1. Start your communications program and access the APS
Command Mode. If the password prompt is displayed,
enter the Supervisor Password.
2. When the APS command prompt appears, type /U and
press [Enter]. The APS will prompt you to configure your
communications program to receive an ASCII download.
a) Set your communications program to receive an ASCII
format download, and the specify a name for a file that
will receive the saved parameters (e.g. APS8M.PAR).
b) Disable the Line Wrap function for your terminal
emulation program. This will prevent command lines
from being broken in two during transmission.
3. When the communications program is ready to receive the
file, return to the APS-8M's Save Parameter File menu, and
press [Enter] to proceed with the download. APS-8M
parameters will be saved on your hard drive in the file
specified in Step 2 above.
9-1
APS-8M User’s Guide
4. The APS-8M will send a series of ASCII command lines
which specify the currently selected APS parameters. The
last line of the file should end with a “/G-00” command.
When the download is complete, press [Enter] to return to
the "APS>" command prompt.

Restoring Saved Parameters
This section describes the procedure for using your
communications program to send stored parameters to the APS.
1. Start your communications program and access the APS
Command Mode; if the password prompt is displayed, enter
the Supervisor Password.
2. Configure your communications program to upload an
ASCII text file.
3. Upload the ASCII text file with the saved APS parameters.
If necessary, key in the file name and directory path.
4. Your communications program will send the specified
ASCII text file to the APS-8M. When the communications
program is finished with the upload, make certain to
terminate the Upload mode.
Note: If the APS detects an error in the parameters
file, it will respond with the “Invalid Parameter”
message. If an error message is received, carefully
check the contents of the parameters file, correct the
problem, and then repeat the upload procedure.
5. If the parameter upload procedure is successful, the APS
will send a confirmation message, and then return to the
"APS>" command prompt. Type /S and press [Enter], the
APS Status Screen will be displayed. Check the Status
Screen to make certain the unit has been configured with
the saved parameters.

10. Upgrading APS-8M Firmware
When new, improved versions of the APS-8M operating firmware
become available, the /UF (Upgrade Firmware) function can be
used to update the APS-8M unit to the new firmware version.
Updates can be uploaded to the unit via SetUp Ports one and two,
or via the internal modem port (Port 8). To install a firmware
update, proceed as follows:
Note: All other ports will be disabled during the
firmware upgrade procedure.
1. Obtain the update file. Firmware modifications can either
be mailed to the customer on a 3.5" diskette, or
downloaded from WTI via modem. Place the diskette in
your diskette drive and/or copy the file to your hard drive.
2. Access the APS command mode. If the password prompt is
displayed, key in the Supervisor Password. The Upgrade
Firmware feature is only available in Supervisor Mode.
3. When the APS command prompt appears, type /UF and
then press [Enter]. The APS-8M will display a screen
which offers the following options:
a) Continue Upload and Keep Current Parameters: To
proceed with the upgrade, while retaining current, userdefined parameters, type 1 and press [Enter]. All
parameter settings will be restored when the upgrade is
complete.
b) Continue Upload and Default System: To proceed
with the upgrade, and reset parameters to default
settings, type 2 and press [Enter]. When the upgrade
is complete, all parameters will be set to default values.
Note that if the Firmware Upgrade is performed via
modem, Modem Port parameters will not be defaulted
until after you hang-up and disconnect from the unit.
c) Abort Upload: To cancel the upgrade and return to the
command prompt, type 3 and press [Enter].
10-1
APS-8M User’s Guide
4. Use your communication program's (e.g. HyperTerminal's)
upload function to transfer the upgrade firmware to the
APS-8M unit. Select ASCII file format, and then specify
the filename and directory location where the firmware
upgrade file resides.
Note: The Upload function will time-out after one
minute of inactivity. If the function times out, type 1
and press [Enter] to continue, or press [Esc] to abort.
5. If the upload is successful, the APS-8M will prompt the
user to continue the upgrade or abort.
a) Upgrade: To continue with the upgrade, type 1 and
press [Enter]. APS-8M will erase the previous
firmware, move new firmware from data flash to
program flash memory, calculate and store the new
checksum, and reboot. Do not attempt to reconnect to
the APS-8M until the RDY indicator blinks to indicate
the process is complete.
b) Abort: To abort the procedure, type 2 and press
[Enter].
6. Incomplete Upload: If the upload is interrupted, timesout, or if the file is corrupted during transfer, the APS-8M
will display a screen which asks for user confirmation
before proceeding. To proceed, type 1 and press [Enter],
then return to Step 4 above.
7. Emergency Recovery: In the rare event that the APS-8M
operating system becomes corrupted during installation,
front panel indicators will blink five times and the unit will
automatically switch to Emergency Recovery Mode.
Please contact WTI Customer Service for further
instructions.
When firmware upgrades are available, WTI will provide the
necessary files via modem or mailed diskette. At that time, an
updated Users Guide or addendum will also be available.

11. Command Reference Guide
11.1. Command Conventions
The commands described in this section conform to the following
conventions:
· Slash Character: Most APS commands begin with the
Slash Character (/).
· Apply Command to All Ports: When the asterisk character
is entered as the argument of the /D command (Disconnect
Port), or the /E command (Erase Buffer) the command will
be applied to all ports. For example, to erase all port
buffers, type /E * [Enter].
· Port Name Wild Card: It is not always necessary to enter
the entire port name. Port names can be abbreviated in
command lines by entering the first character(s) of the name
followed by an asterisk (*). For example, a port named
"SERVER" can be specified as "S*". Note however, that
this command would also be applied to any other port name
that begins with the letter "S".
· Suppress "Sure?" Prompt: When the /D (Disconnect
Port), /E (Erase Buffer), or /I (Default and Test Unit)
commands are invoked, the /Y option can be included in the
command line to override the "Are you Sure (y/n)?" prompt.
For example, to disconnect Port 8 without displaying the
"Sure?" prompt, type /D/Y 8 [Enter].
· Enter Key: All commands are invoked by pressing [Enter].
· Command Mode: APS-8M Ports will only recognize
commands when the Command Mode has been activated.
The Command Mode can be accessed from a free Any-toAny or Modem Mode Port. To access the Command Mode,
proceed as described in Section 5.1.
· Connected Ports: When two ports are connected, most
APS-8M commands will not be recognized by either of the
connected ports. The only exception is the Resident
Disconnect Sequence (Default = ^X ([Ctrl] plus [X])).
· Configuration Menus: To exit from a configuration menu,
you must press [Esc].
11-1
APS-8M User’s Guide
11.2. Command Response
When commands are sent to the APS-8M, the unit can respond
with either verbose (English Text) or terse messages (numeric /
abbreviated). The default message type for all ports can be set to
either terse or verbose using SetUp Switch Six.
After the unit is installed and configured, the port configuration
command (/P) can specify an individual response format for each
port. In addition to the Terse and Verbose response modes, the
port configuration commands can also select the Quiet Mode.
When the Quiet Mode is selected, the port will not send
messages in response to commands.
The table below summarizes the various response messages for
both the Terse and Verbose modes.
