InRoom Controller - Operating Instructions
1. Presentation of the system
The InRoom Controller offers maximum possible operating safety for industrial applications and a versatile
operator interface. There are two interfaces with one
controller.
The InRoom Controller works by having each cooling
unit possess its own controller while all controllers can
be linked together in a bus system.
This way a natural redundancy is obtained that causes
the system to function with the least expense.
The second interface can be accessed using a computer. Using the screen of a Laptop or PC provides the
best way of visualizing parameter settings. This is the
most comfortable way of doing a component-related
configuration.
Beyond the basic air conditioning functions, the control
system provides some interesting features like an intelligent management of high/low pressure-alarms, a proportional fan speed control which opens a wide spectrum
of applications and time-based functions like:
- week timer
- unit sequencing within definable unit groups
The heart of the control system is the I/O controller on
which up to 4 EAIO/EDIO boards for additional in- and
outputs can be installed. The exploitation of the third
dimension provides maximum accessibility and an easy
board exchange in case of modifications.
The control systems manages four busses:
1. IIC-bus for the communication between the I/O
controller and the EAIO/EDIO boards.
2. RS485 IO-bus for the communication among the
cooling units.
3. RS485 BMS-bus for the communication with a
building management system.
4. RS485 Aux-bus for the communication with optional components capable of bus connection.
For service purposes like software download and control
by a remote computer a RS232 interface is located on
the I/O controller in the same way as on the InRoom
Controller interface.

The EAIO-board is an extension board for analogous
inputs and outputs. It can be attached to the I/O
controller board at any of the four sockets and will
be recognized by the IOC due to a self test.
There are several jumpers on board - five for each
input - which serve to adapt the board to different
sensor types.
How to use the Jumper setting table:
- Choose the analogous input at which you have
connected a sensor.
- In the same line you can see the jumpers which
relate to this input.
- In the lower part of the table you can read in
each column the jumper setting depending on
the sensor type you connected.
Example:
You have connected a PT100 at AIN 8. The
corresponding jumpers are 301-304, 300. Jumper
301,303,304 must be set on position 2-3, Jumper
300 on 1-2 and Jumper 302 not at all.

3. Operator interface
3.1 I/O Controller
A keyboard is used to operate the I/O controller by using
specified commands that follow an easily understood
syntax.
To establish the connection from a PC to the IOC a 9-line
cable with SUB-D 9 connectors at both ends (crossed
type), which can be obtained as an option, is needed.
A terminal program is also needed. You can download
the terminal program "Service" from the APC website
www.apc.com. Connect the cable at a serial port of
your PC and at the service port X15 on the IOC. Start
the terminal program.
You can now communicate with the connected I/O controller (ioc), and in return the IOC sends the following
prompt to your PC:
"ioc ##:>", where ## represents the bus id.
The commands can be classified into three major categories:
1. Bus specific control commands
2. Commands related to cooling unit components
3. Commands concerning the whole cooling unit
1. Bus command
invite ##
del ##
iobus
checkbus
spreadbusconf
2. Component command

Each command displays a detailed help for further
parameters (if there are any) when it is followed by "h"
such as "comp h".
A command of the second (component command) or
third category (Cooling unit command) which is typed
in without any parameters displays all the information
about its subject (except "loaddefault ###" which is an
execution command).

The commands on a light-gray (yellow) background need
no further parameters. The commands which are followed
by a number need this number because there are several
components of the same type.
The bus commands except for „iobus“ are control commands that are executed after pressing the enter key.
The bus commands on a dark-gray (green) background
need the bus I.D.s of their respective units in order to
execute.
InRoom Controller - Operating Instructions
Now the bus commands in detail:
- The invite command plus bus I.D. adds a bus participant.
- The del command plus bus I.D. excludes the participant from the bus and sends the new I/O-bus
configuration to all participants.
- The checkbus command checks every I.D. address
from 00 to 31 for the presence of a bus participant and
updates the stored bus configuration accordingly.
- The spreadbusconf command distributes the bus
configuration to all participants.
- The iobus command edits the stored I/O-bus configuration.
General
The numbering of any digital or analogous in- or output
begins with number 1. Despite this the digital/analogous
in- or output 0 can be assigned to any component. This
will allow the component to stay part of the configuration
even if it does not take part in the control.
A double assignment of in- and outputs is not possible
with the exception of in-/output 0 and the alarm priorities
(relays).
Whenever a parameter is expressed by a logical function,
0 means no, disabled; 1 means yes, enabled.
If at unit start no valid configuration is found, the configuration for single refrigerant circuit-units DX1 is loaded.
Note that no year below 2000 can be entered.

4. Bus communication
The maximum configuration consists of 16 cooling units with an I/O controller and an
InRoom Controller. One of the features of the controller is its facility for bus operation.
All that is needed is a shielded cable with two lines twisted in pairs, which are connected from unit to unit at the terminals 56-59 of each I/O controller (IOC). In the example
below the bus termination of the two units that form the end of the bus (IOC 01 and
IOC 17) must be enabled.
The example of a RS485 bus shows a typical application with 7 IOCs and 1 InRoom
Controller.

The bus address or bus ID is adjusted with the dip-switches on the IOC. The table at the
right shows the corresponding adjustment for all possible bus IDs. The counting begins
with 0 and ends with 31. A "1" means a dip-switch is in the ON position.
On an InRoom Controller the bus-ID is adjusted in the global status line (See chapter
5. Controller Start).
An IOC is delivered with the ID 01 as standard, an InRoom Controller has the ID 31 as
standard. After having provided all units (IOCs) with a different bus-ID, the units must
be declared as participants of the bus, for the bus exists up to now only physically. (See
next page).

4.1 Bus with InRoom Controller + IOC
Configuration of the bus participants
1. Configure the address of the bus participants with the DIP-switches or in the global status line at the InRoom
Controller.
2. Declare the bus participants; there are 3 ways to do this:
a. Move DIP-switch 6 from ON to OFF.
b. Use the selector key to mark all units from an InRoom Controller when the bus with ID 31 is marked. Press
the confirmation key OK and enter the Service password.
c. Connect a laptop to any IOC and enter the command "invite me" or "invite ##", where ## represents
the bus-ID of the IOC to which you are connected. Then use the command invite ## with each bus-ID of
the connected elements to declare other participants.
3. Check the presence of the bus participants in the overview on the display of the InRoom Controller or by using
the command iobus.
Deleting bus participants from the bus configuration
1. Delete a bus participant by typing the command del ## .
Adding bus participants to the bus configuration
1. Adjust a free bus-ID. If the bus participant, which will be added, is an IOC, adjust the DIP-switches. If the bus
participant, which will be added, is an InRoom Controller, adjust the bus-ID in the global status line. (See „Controller start“ on page 21).
2. Declare the bus participant by using the command invite ## with the adjusted bus-ID.
Address modification of participants
1. Delete the bus participant from the configuration.
2. IOC: change the dip-switch adjustment correspondingly. InRoom Controller: change the bus-ID in the global
status line.
3. Declare the bus participant by the command invite ## with the adjusted bus-ID.
4.2 Special cases
Adding an IOC with invalid bus configuration to a consisting InRoom Controller/IOC-configuration
1. Separate the new unit with invalid configuration from the bus.
2. Delete the IOC with invalid configuration from another IOC (with valid configuration) del ##.
3. Adjust a free address with the DIP-switches at the new IOC.
4. Delete the stored bus configuration of the new IOC (either each single address with del ## or globally with
the command checkbus; this command scans the addresses and deletes every unit that is not present).
5. Connect the new unit to the bus.
6. Invite the new IOC by another IOC by typing the "invite ##" command.
General Note:
If there is data traffic on the bus, a new unit can only be invited by a valid/active bus member. A bus member is
valid/active if the TX1-LED on the IOC board is red.

InRoom Controller - Operating Instructions
5. Controller start
After having switched on the power supply of the InRoom Controller the window
illustrated at the right will appear. This window displays the maximum number
of 32 bus participants (bus ID 0-31).
An I/O controller is displayed by a square frame containing the local temperature and humidity. A gray frame signifies that the unit is in a stop state, and
a black frame indicates that the unit is in operation. An IOC symbol without
measured values indicates that the IOC is not reachable, either because it is
switched off (no voltage) or due to a bus fault. The other symbols contain an
abbreviation for the controller type:
context status line
AT - InRoom Controller,
ME - InRoom Controller at which these windows are displayed.
The bus-ID can be deducted from the location in the scheme. Line 1 contains
the bus participants 0 - 7 from left to right; line 2, 8-15; line 3, 16-23; line 4,
24-31.
A space signifies that a unit with a corresponding bus-ID does not exist.
A symbol/unit that is selected displays inversely. In the window on top of the
page the InRoom Controller is selected. It appears inversely with white letters
on a black background. In the window below, the IOC is selected.
The context status line contains the bus-ID and the global address of the
selected bus participant.
The global status line contains the bus-ID, the global address of the InRoom
Controller, and the clock.

rows which serve to easily relocate single submenus
within the overview.
The columns for the Control menu are named from A to
F, the columns for the Service menu from K to V.
On each page there is one top row without a number,
which contains the top level menu and seven rows for
the submenus which are named from 1 to 7.
There are up to 4 submenu levels.The first submenu
level is horizontally located. All other submenu levels
are vertically located. The second submenu level on an

Setpoint & Limit Values
Control
The first two items of the control menu concern the adjustment of setpoints and limit
values. The limit values are decisive for the alarms "temp/humidity too high/low".
Two temperature setpoints can be adjusted, setpoint 1 concerns the operation by day,
whereas setpoint 2 concerns operation at night according to the week timer (page
72).
The limit values for the room air sensor, the supply air sensor, and the water sensor are
displayed. The "MIN" column contains the values for the lower temperature limit and
the "MAX" column contains the values for the upper temperature limit.
If the measured value is lower than the minimum room air temperature, the alarm "Room
temperature too low" is displayed.
In the following window you can adjust three parameters for the room temperature limit
alarms and for the supply air temperature limit alarms each.
1. Whether the corresponding alarm shall release a common alarm (1=yes).
2. The alarm priority, where the corresponding alarm is assigned to an alarm relay with
this number (adjusted as alarm priority).
3. The alarm delay in seconds.
For the water limit alarm the following parameters:
- Common alarm
- Alarm priority
- Alarm delay
can only be adjusted by commands.

Compressor (part 2)
The low pressure alarm can be managed
in a way to avoid a premature and unnecessary service intervention.
If the LP switch releases, the compressor
is stopped and restarted after the compressor pause has elapsed. The LP alarm
is inhibited during the winter start delay
(see page 70).
This way the controller tries to bypass
temporary LP alarms.
You can limit the number od compressor
restarts in "RESTARTS" ➐b within a time
space which you can adjust in the first
line ➐.
If the maximum number of restarts is
reached, the LP alarm is released and
the compressor is definitely switched off.
Using the optional LP-sensor you can adjust a threshold ➐a which marks the lower
limit for the permissible pressure range.
With a HP sensor (either part of G-valve
or separate option) high pressure alarms
can be equally managed for the same
reasons as LP alarms.
You can limit the number od compressor
restarts in "RESTARTS" ➑b within a time
space which you can adjust in the fourth
line ➑.
If the threshold ➑a of the HP is exceeded the adjusted number of times, the
HP alarm is released and the measure
which you have adjusted in HP mode ➒
is taken.

G-valve
The pressure setpoint is entered in the 2nd

The pre-start serves to provide a sufficient
flow for the heat absorbing medium and to
pre-cool the heat absorbing medium. When
compressor operation is requested, the
G-valve opens and the compressor start is
delayed by the pre-start time. ➋
The pre-open value is the G-valve opening
which should be obtained during the prestart time. ➌
To avoid a constant discrepancy from the
set value there are three parameters, which
imitate the behavior of an integral control.
The control factor ➍ is the decisive value, by
which the extent of the control correction is
adjusted in the way of calculating the actuating variable after the lapse of an adjustable
control cycle ➎ (0-10 sec) according to the
following formula:
Snew = Sold - f • (set value - actual value)
S: actuating variable - in this case, valve

f: control factor
Set value: condensation pressure
To avoid a drastical change you can adjust
a maximum control correction ➏ (0 - ±10%).

type is entered as a negative difference to
the room temperature setpoint. ➊
The hysteresis for the heating stop is only
valid for heatings with on/off-control.➋
For proportional e-heatings/hot water
reheats you can adjust a gradient, which

Setting the priority for the heating alarm
➏ means assigning the corresponding

Only the first heating can be proportional.
If this is the case and if there are several
heatings (up to 4), only the start value
and the gradient of the first heating are
decisive for the control. Each time the proportional heating reaches 100% heating
capacity another reheat is added and the
first heating is reset to 0%. This way up to
four individual heatings act as one proportional heating. (See illustration 1).

Dehumidification (Part 2)
There two ways of achieving dehumidification:
1. By reducing the fan speed, this is the only way of dehumidification for CW-units.
2. By shutting down a part of the evaporator with a solenoid
valve.
Dehumidification type is chosen by the controller according
to the following conditions: Fan speed reduction or compressor operation with a dehumidification valve present. The two
dehumidification types can never be applied simultaneously.

Fan (Part 2)
With the parameter "START 100%" ➊ you
adjust a time which must elapse before the
control begins. This way an airflow alarm is
avoided which could occur due to the fan
inertia. During this time the fan is operated
with 100% speed.
Using the "PRERUN" parameter ➋ you
adjust the delay for the inhibited start of
all components, except the glycol pump, in
relation to the control start with alarm monitoring. This way the Pre-run parameter has
the effect of a cooling unit start delay. Using
different pre-runtimes for different units
saves power and ensures that the power
supply of the building will not overcharge.
The fan over-run time ("HUNTING TIME")
➌, which you can adjust, serves to reject
hot or cold air in the cooling unit and avoids
an accumulation of heat at the reheat or of
cold at the evaporator.
If during a time which you adjust with "REDUCE TIME" ➍ no action (cooling, heating,
humidification, dehumidification) has been
taken, the fan speed is reduced by the pert/sec centage which you adjust with "REDUCE
SPEED" ➎.
The "FILTER OFFSET" ➏ is entered as a
positive difference to the maximum speed.
If a filter alarm is released, the maximum
%
speed will be increased by the filter offset
100
in order to overcome the higher resistance
of a clogged filter.

The following decision processes are used by the
controller for the fan speed calculation.
The fan speed nmaxDX or nmaxCW is chosen according to the cooling priority and the conditions for
a malfunction change-over. (For details about the
cooling priority, see page 71.)
Then four queries are passed, which use a multiplication of the speed with a factor, if positively answered.
Finally the algorithm checks whether the minimum
speed is kept and whether the conditions for the
REDUCE SPEED are kept, which can bypass the
minimum speed as the sole reduction.

Example 1:
Example 2:
n = nmaxDX
n = nmaxCW
supposing: condition not ok
n = nmaxDX = 100%
supposing: condition not ok
n = nmaxCW = 90%
supposing: condition ok
n = 100% x (100% - 10%)
n = 90%
supposing: condition ok
n = 90% x (100% - 10%)
n = 81%
supp.: condition not ok
n = 81%

supposing: condition ok
n = 90% x (100% - 20%)
n = 72%
supp.: condition not ok
n = 81%

supposing: condition ok
n = 72% x (100% - 30%)
n = 50.4%

supposing: condition ok
n = 50.4% x (100% + 10%)
n = 55.44%
supposing: condition ok

The "DEHUM.SPEED" ➊ is entered as a
negative difference in % to the maximum
speed. This is the fan speed for the first option
of dehumidification.
The "UPS SPEED" ➋ is also entered as a
negative difference in % to the maximum
speed. When the controller receives a UPS
signal the controller will apply this reduced
speed for an emergency operation.
The parameters:
- control cycle ➌

➐
If the cooling unit has low airflow during nominal operation, the fan speed can be raised
when the temperature setpoint is exceeded.
The fan speed increase depends on the
temperature difference to the setpoint.
For this way of cooling the room by increasing the fan speed you adjust a positive
temperature difference ➏ to the setpoint,
T/°C which represents the start point of the speed
increase.
Then you adjust a maximum speed ➑ for the
overload operation and another temperature
difference ➐ to the setpoint, which marks the
end of the proportional fan speed increase.
Having attained the second temperature
difference, the fan is operated with the
maximum speed for the overload operation.
This speed is kept even if the temperature
continues to rise.

Control/Parameters
Using the room control with supply air
limitation causes the control to take place
using a T/H sensor in the return air intake
and a second T/H sensor in the supply
air intake. The control takes place in the
same way as room air control, the temperature setpoint is shifted only when the
supply air temperature exceeds the start
temperature ➋. The extent of the setpoint
increase is determined by a factor which
you enter, as a gradient ➌, in the menu.
The relationship, according to which the
setpoint increase happens, is made clear
by the graph on the left side. A steep
gradient drastically corrects the failure
to meet the supply air temperature, but
has the risk that the control circuit starts
to oscillate.
With humidity control the setpoint shift
takes place in the opposite direction. If the
adjusted starting humidity ➍ is exceeded
by the measured supply air humidity, the
setpoint is reduced. You can also enter a
gradient factor ➎ for this. The relationship
is shown in the graph on the right side.

The supply air control with room air limitation is based on the same control principle
as the supply-air limited room air control.
Only here the setpoint shift works in the
opposite direction, because it works on
the basis that the supply air is colder than
the return air.
If the room temperature exceeds the start
temperature entered, the temperature
setpoint is reduced.
If the room humidity drops below the

setpoint is increased.

Q5
Sequencing
Service
The zone concept is based on the idea to
obtain a homogeneous room climate within a
determined space by distributed generation
of conditioned air. Within a zone only one
room temperature exists, which is calculated
as the average value of all connected room
temperature sensors of the units in operation; this also applies to the room humidity,
supply temperature, and supply humidity. The set values can be individually adjusted
for each unit, but they should only vary slightly.
There are two zone specific functions:
1. Sequencing
2. CW standby management
1. Sequencing
Within a zone you can have a unit sequencing with change-over dependent on
time and failure.
Time dependent change-over
(normal sequencing)
e. g. with 2 standby units:
1. cycle
unit 07, 11 standby
2. cycle
unit 08, 14 standby
unit 11, 01 standby
3. cycle
etc.
The following parameters must be specified for this:
➊. Unit assignment
A zone is defined by the assignment of units. A maximum of 32 zones can be
defined with the adjustments from 1 to 32. Zone 0 means that the unit is assigned
to no zone. The assignment is made individually for each unit.
Zone 01
Stand
-by
Unit 01
➋. Standby units
When a sequencing takes place the zone must contain at least one standby unit.
This setting must be made for each unit/IOC by means of the ON/OFF-button on
the InRoom Controller.
Unit 08
➍. Emergency temperature (zone parameter)
Unit 14
Zone 01
This temperature is the new sepoint when emergency operation is enabled.
Enabling the test sequencing ➏ with the fixed cycletime of 5 minutes helps you to
check the sequencing function.
Unit 11
Cycle 1
This entry is optional. If the number, adjusted here, is reached, the emergency
operation will be put into force.
To let the standby units (set under item ➋) participate in the sequencing, they have
to be locally switched on by means of the ON/OFF-button on the InRoom Controller.
For this the corresponing unit must be selected in the bus overview window.
Unit 07
Stand
-by
➌. Number of defective units (errorunits) (zone parameter)
Time dependent changeover
The cycletime ➎ determines the lapse of time after which a changeover will periodically take place. This means that the standby status is changed over the units
one by one. With the setting 0 (hrs) no sequencing is made.
Setting the cycletime causes the sequencing start after the sequencing menu has
been left.

Definition of valid alarms for one zone
For each zone any number out of 26 alarms in total can be defined as valid alarms.
If such an alarm occurs the corresponding unit is switched off and notified as defective.
All 26 alarms are defined as valid alarms by default. The alarm "unit not available"
can not be deleted from the alarm list. This alarm is always part of the valid alarms
and appears due to a bus failure or when the unit has locally been switched off.
After the failure of a unit a standby unit is switched on. With the switching on of the

last available standby unit the time dependent sequencing is interrupted.
When the previously adjusted number of defective units in one zone is reached the
emergency operation is enabled for all zones.
Emergency operation means that the emergency temperature of the triggering zone
is accepted as the new temperature set value for all the zones.
The number of defective units is independent of the number of standby units which
have been started. For example, even if the failing unit capacity of one zone is
completely equalled by the start of standby units, the defective units are counted
as lacking.

2. CW Standby Management
The CW standby management can be carried out with CW units and Dualfluid units
with CW cooling priority. The basic idea is
to share the heat load permanently with as
many units as possible in order to reduce
the fan speed of all units and thus to save
energy. As a result, the provided standby
units must constantly take part in the cooling
process. The total airflow is below the maximum airflow possible and is equalled in case
of failure of one or more units by increasing
the fanspeed of the remaining units.
Use "MAXFANSPEED" ➑ to adjust the fan speed which is to be kept in the zone
when all units are running. Use CW-ENERGY-SAVE ➒ to enable the CW-standby
management and to turn on all standby units of the zone. Both parameters are
related to the zone and only need to be adjusted at one unit of the zone.
The table beside displays how many units in
a zone are necessary to keep the total airflow
at the indicated fan speed in the left column,
when "f" units have failed.
This correlation is represented by the following formula.

A cooling unit is switched off as a defective unit if a valid alarm occurs at this unit,
in the same way as in the sequencing.
When a Dualfluid unit changes over to DX operation due to a fault like a water
temperature exceeding the GE-off limit (see page 71), this unit applies the nMaxDX
fan speed which is higher than the MAXFANSPEED of the CW standby management.
The fan speed of the other units is not affected by this.

InRoom Controller - Operating Instructions
8.1 Loading new Software
For the control system there are two types of software. The
essential control software is located in the Flash-EPROM
on the IOC-board. The second software contains the menu
structure and is located in the EPROM of the InRoom Controller board.
The control parameters in the IOC are resistent and do
not have to be re-entered after loading the software. This
is also the case for the IO bus configuration of the InRoom
Controller.
To load software in the flash-EPROM of the IOC you must
connect the service port of the IOC to a serial interface
of your computer (System requirements: Windows 95/98/
NT/2000/ME/XP) by means of a RS232 modem connection.
Turn off the master switch. Set the jumper JP7 to position 2-3.
Turn on the master switch. The IOC is now in the Downloadmode. Start the program "InRoom-Service.exe" on your PC.
This program can be downloaded from the APC website.
After the new software has been loaded, the master switch
must be turned off and the jumper JP7 must be set in the
position 1-2.
To load software in the flash-EPROM of the InRoom Controller you must connect the service port of the InRoom
Controller to a serial interface of your computer by means
of a RS232 modem connection.
Turn off the master switch. After this the jumper X6 must be
set to position A. Turn on the master switch. The InRoom
Controller is now in the Download-mode. Start the program
"InRoom-Service.exe" on your PC.
After the new software has been loaded, turn off the master
switch and set the jumper X6 to position B. When turning on,
ensure that the new version number is correctly displayed.

8.1.1 Operation of the program "InRoom-Service.exe"
With an up-to-date Windows XP system the program must only be copied onto the computer hard disk and can
directly be started by a doubleclick. The files (InRoom-Service.exe and IOC-Service.exe) must be stored in the
same folder. With former Windows XP versions, Windows 2000, Windows ME, and Windows 98 the install-package
that can be obtained from the APC website must be carried out.
InRoom - Service
Start InRoom-Service.exe und click on the button "Terminal",
which starts the program IOC-Service.exe.
Select an interface to the PC (COM 1 - 9) and check the
connection to the IOC or InRoom Controller by pressing the
Return key. If you receive a response from the controller the
connection is established.
Clicking on the "Download" button opens a window, in which
you can enter the file that will be loaded. This is done by clicking on the button "Select file," which opens a dialog box for
the selection of a file. The file is a hexadecimal file with the
extension *.h86.
The file name gives information about the software destination.
AT-Vxxx.H86 is for the InRoom Controller. IOC-Vxxx.h86 is
for the IO-controller. The number behind the V indicates the
version.
You can start the download by clicking the Start button. The
single steps are indicated in the "Help/State" line, the progress
of each step in the "Download Progress" line.
Clicking on "Close" closes the download window. Pressing the
"End" button quits the program IOC-Service.
Concerning the block size and the transmission rate, you can
take the preadjusted values (1024 Bytes and 38400 kBit/s).
The transmission will then take approximately 2 minutes for
each software. The rate may need to be reduced if using a
longer cable.

InRoom Controller - Operating Instructions
9. Network Management Card
9.1 Quick Configuration
The InRoom Precision Air Conditioner is shipped with a Network Management Card that enables you to manage
the air conditioner over your network. You must set up the Network Management Card to control the InRoom Precision Air Conditioner through a network.
The Network Management Card comes pre-assembled to an interface board using two sets of pin connections.
The interface board then connects to the controller board of the InRoom Precision Air Conditioner using a DB-15
connection, and a network connection is made by inserting an RJ-45 cable in to the ethernet port on the interface
board. The Network Management Card can be configured via a serial cable connected to the service port of the
controller board by using the nmcservice command.
Overview
You must configure the following TCP/IP settings before the InRoom Precision Air Conditioner can operate on a
network:
• IP address of the Network Management Card
•
Subnet mask
•
Default gateway
Note: Never use the loopback address (127.0.0.1) as the default gateway address for the
Network Management Card. Doing so will disable the card and will require you to reset TCP/IP
settings to their defaults using a local serial login.
If a default gateway is unavailable, use the IP address of a computer that is located on the same
subnet as the Network Management Card and that is usually running. The Network Management
Card uses the default gateway to test the network when traffic is very light.
See “Watchdog Features” online at www.apc.com for more information about the watchdog
role of the default gateway.
TCP/IP configuration methods
Use one of the following methods to define the TCP/IP settings needed by the Network Management Card:
•
APC Device IP Configuration Wizard (See “APC Device IP Configuration Wizard” on page 98.)
•
BOOTP or DHCP server (See “BOOTP and DHCP configuration” on page 98.)
•
Networked computer (See “Remote access to the control console” on page 100.)
InRoom Controller - Operating Instructions
97
APC Device IP Configuration Wizard
You can use the APC Device IP Configuration Wizard at a computer running Microsoft Windows 2000, Windows
2003, or Windows XP to configure a Network Management Card.
1. Insert the Utility CD into a computer on your network and click the „Device IP Configuration Wizard“
link.
2. Launch the Device IP Configuration Wizard, when prompted, or, if prompted to restart the computer,
access the Wizard from the Start menu after the computer has restarted.
3. Wait for the Wizard to detect the unconfigured Network Management Card, then follow the on-screen
instructions.
Note: If you leave the Start a Web browser when finished option enabled, you can use apc
for both the user name and password to access the Network Management Card through your
browser.
BOOTP and DHCP configuration
TCP/IP Configuration, which you access by selecting the Administration tab, the Network option on the top
menu bar, and TCP/IP on the left navigation menu, identifies how the TCP/IP settings will be defined. The possible
settings are Manual, DHCP, BOOTP, and DHCP & BOOTP (the default setting).
Note: The DHCP & BOOTP setting assumes that a properly configured DHCP or BOOTP server is
available to provide TCP/IP settings to Network Management Cards.
With Boot Mode set to DHCP & BOOTP (the default setting), the Network Management Card attempts to discover
a properly configured server. It first searches for a BOOTP server, then a DHCP server, and repeats this pattern
until it discovers a BOOTP or DHCP server.
See “BOOTP” on this page or “DHCP” on page 99 for configuration information.
BOOTP. You can use an RFC951-compliant BOOTP server to configure the TCP/IP settings for the Network Management Card.
1. Enter the Network Management Card MAC and IP addresses, the subnet mask and default gateway
settings, and an optional bootup file name in the BOOTPTAB file of the BOOTP server.
Note: The MAC address is located on a label on the underside of the Network Management
Card. The MAC address can also be accessed by using a Web browser to log in to the Network
Management Card and then selecting the Administration tab, the Network option on the top
menu bar, and TCP/IP on the left navigation menu.
98
InRoom Controller - Operating Instructions
2. When the Network Management Card reboots, the BOOTP server provides it with the TCP/IP settings.
– If you specified a bootup file name, the Network Management Card attempts to transfer that file
from the BOOTP server using TFTP or FTP. The Network Management Card assumes all settings
specified in the bootup file.
– If you did not specify a bootup file name, the Network Management Card can be configured remotely by using the control console or the Web interface (user name and password are both apc, by
default).
To create the bootup file, see your BOOTP server documentation.
DHCP. You can use an RFC2131/RFC2132-compliant DHCP server to configure the TCP/IP settings for the Network Management Card.
This section briefly summarizes the Network Management Card communication with a DHCP server.
For more detail about how a DHCP server is used to configure the network settings for a Network Management Card, see “DHCP Configuration” in the InRoom Precision Air Conditioner User’s Guide.
1. A Network Management Card sends out a DHCP request that uses the following to identify itself:
– A Vendor Class Identifier (APC by default)
– A Client Identifier (by default, the MAC address value of the Network Management Card)
– A User Class Identifier (by default, the identification of the application firmware of the Network Management Card)
2. A properly configured DHCP server responds with a DHCP offer that includes all of the settings that
the Network Management Card needs for network communication. The DHCP offer also includes the
Vendor Specific Information option (DHCP option 43). By default, the Network Management Card will
ignore DHCP offers that do not encapsulate the APC cookie in the Vendor Specific Information option
using the following hexadecimal format:
Option 43 = 01 04 31 41 50 43
where
– the first byte (01) is the code
– the second byte (04) is the length
– the remaining bytes (31 41 50 43) are the APC cookie
See your DHCP server documentation to add code to the Vendor Specific Information option.
To change the control console DHCP Cookie Is setting, use the Advanced option in the TCP/IP
menu. See “Remote access to the control console” on page 100.
To change the Web interface setting Require vendor specific cookie to accept DHCP Address,
which is enabled by default, first choose DHCP under the TCP/IP Configuration heading by
selecting the Administration tab, the Network option on the top menu bar, and TCP/IP on the
left navigation menu. To disable the APC cookie requirement, click Next to access the DHCP
Configuration page, and unmark the checkbox „Require vendor specific cookie to accept
DHCP Address.“
InRoom Controller - Operating Instructions
99
Remote access to the control console
From any computer on the same subnet as the Network Management Card, you can use ARP and Ping to assign
an IP address to a Network Management Card, and then use Telnet to access the control console of that Network
Management Card and configure the needed TCP/IP settings.
Note: After a Network Management Card has its IP address configured, you can use Telnet, without
first using ARP and Ping, to access that Network Management Card.
1. Use ARP to define an IP address for the Network Management Card, and use the MAC address
of the Network Management Card in the ARP command. For example, to define an IP address of
156.205.14.141 for a Network Management Card that has a MAC address of 00 c0 b7 7E 19 F3, use
one of the following commands:
– Windows command format:
arp -s 156.205.14.141 00-c0-b7-7E-19-F3
– LINUX command format:
arp -s 156.205.14.141 00:c0:b7:7E:19:F3
Note: The MAC address is located on a label on the underside of the Network Management
Card.The MAC address can also be accessed by using a Web browser to log in to the Network
Management Card and then selecting the Administration tab, the Network option on the top
menu bar, and TCP/IP on the left navigation menu
2. Use Ping with a size of 113 bytes to assign the IP address defined by the ARP command. For the IP
address defined in step 1, use one of the following Ping commands:
– Windows command format:
ping 156.205.14.141 -l 113
– LINUX command format:
ping 156.205.14.141 -s 113
3. Use Telnet to access the Network Management Card at its newly assigned IP address.
For example:
telnet 156.205.14.141
4. Use apc for both user name and password.
See “Control console” on page 101 to finish the configuration.

9.2 Access a Configured Unit
Overview
After the InRoom Precision Air Conditioner is running on your network, you can use the interfaces summarized
here to access the InRoom Precision Air Conditioner.
See the User’s Guide for more information on the interfaces.
Web interface
As your browser, you can use Microsoft® Internet Explorer 5.5 and higher (on Windows operating systems only),
Firefox 1.x by Mozilla (on all operating systems), or Netscape® 7.x and higher (on all operating systems) to access
the Management Card through its Web interface. Other commonly available browsers also may work but have not
been fully tested by APC. To use the Web browser to configure InRoom Precision Air Conditioner options or to view
the event log, you can use either of the following:
•
The HTTP protocol (enabled by default) provides authentication by user name and password but no
encryption.
•
The more secure HTTPS protocol provides extra security through Secure Sockets Layer (SSL) and encrypts user names, passwords, and data being transmitted. It also provides authentication of InRoom
Precision Air Conditioners by means of digital certificates.
To access the Web interface and configure the security of your device on the network:
1. Address the Network Management Card by its IP address (or DNS name, if configured).
2. Enter the user name and password (by default, apc and apc for an Administrator, or device and apc
for a Device Manager).
3. Select and configure the type of security you want. (This option is available only for Administrators.) On
the Administration tab, select Network on the top menu bar and the access option under the Web
heading on the left navigation menu to enable or disable the HTTP or HTTPS protocols.
See “Security” in the Security Handbook available on the Utility CD or on the APC Web site,
www.apc.com, for information on choosing and setting up your network security.
102
InRoom Controller - Operating Instructions
Telnet/SSH
You can access the control console through Telnet or Secure SHell (SSH), depending on which is enabled. (An
Administrator can enable these access methods in the Web interface by selecting the Administration tab, then
Network on the top menu bar, and the access option under the Console heading on the left navigation menu.)
By default, Telnet is enabled. Enabling SSH automatically disables Telnet.
Telnet for basic access. Telnet provides the basic security of authentication by user name and password, but not
the high-security benefits of encryption. To use Telnet to access the Network Management Card control console
from any computer on the same network:
1. At a command prompt, use the following command line, and press ENTER:
telnet address
As address, use the Network Management Card IP address (or DNS name, if configured).
2. Enter the user name and password (by default, apc and apc for an Administrator, or device and apc
for a Device User).
SSH for high-security access. If you use the high security of SSL for the Web interface, use Secure SHell (SSH)
for access to the control console. SSH encrypts user names, passwords, and transmitted data.
The interface, user accounts, and user access rights are the same whether you access the control console through
SSH or Telnet, but to use SSH, you must first configure SSH and have a SSH client program installed on your
computer.
See the User’s Guide for more information on configuring and using SSH.
Note: The menu structure for administration and device management in the control console differs
from the menu structure for these areas in the Web interface. See the User‘s Guide for an overview
of the control console menus
InRoom Controller - Operating Instructions
103
SNMP
After you add the PowerNet® MIB to a standard SNMP MIB browser, you can use that browser for SNMP access
to the InRoom Precision Air Conditioner. The default read community name is public; the default read/write community name is private.
Note: If you enable SSL and SSH for their high-security authentication and encryption, disable SNMP.
Allowing SNMP access to the InRoom Precision Air Conditioner compromises the high security you
implement by choosing SSL and SSH. To disable SNMP, you must be an Administrator; use the SNMP
option of the Network menu.
FTP/SCP
You can use FTP (enabled by default) or Secure CoPy (SCP) to transfer new firmware to the Network Management
Card, or to access a copy of the event logs of the InRoom Precision Air Conditioner.
SCP provides the higher security of encrypted data transmission and is enabled automatically when you enable
SSH.
Note:If you enable SSL and SSH for their high-security authentication and encryption, disable FTP.
Allowing file transfer to the InRoom Precision Air Conditioner through FTP compromises the high security you implement by choosing SSL and SSH. To disable FTP, you must be an Administrator; use
the FTP Server option of the Network menu.
To access the Network Management Card through FTP or SCP, the default user name and password are apc and
apc for an Administrator, or device and apc for a Device Manager. In the command line, use the IP address of
the unit.
See the User’s Guide to use FTP or SCP to transfer firmware files to or to retrieve the log file from
the InRoom Precision Air Conditioner.

Card or other device through the serial port).
1. Select a serial port at the local computer, and disable any service that uses that port.
2. Use the supplied configuration cable to connect the selected port to the serial port (X15) on the controller board.
Electrical Hazard: Potentially dangerous and lethal voltages exist within the electrical cabinet.
Do not touch components on the electrical panel other than the serial port.
3. Run a terminal program (such as HyperTerminal®) and configure the selected port as follows:
– 9600 bps
– 8 data bits
– no parity
– 1 stop bit
– no flow control
4. Press ENTER to display the IOC XX:> prompt.
5. Type the command nmcservice to access the NMC console port.
6. Press ENTER, repeatedly if necessary, to display the User Name prompt. If you are unable to display
the User Name prompt, verify the following:
– The serial port is not in use by another application.
