Connection Description
BayTech's DS71-MD4 host communication modem module provides an interface that controls user
access to the DS Series data switch and other DS Series connected modules. The DS71-MD4 is a system
data controller that directs operations between the base unit, system modules and externally connected
devices.
4
DS71-MD4 Serial host and 56k Modem
EIA-232 SERIAL CONNECTION
The DS-Series host communications modules have an RJ-45 port which uses an 8-pin crossed modular
cable to connect to a local EIA-232 device such as a computer terminal or external modem. Most serial
computers do not have RJ-45 connections; therefore an adapter is provided with this unit to convert from
a DE-9 connector to an RJ-45 connector (Bay Tech Part No. 9FRJ45PC-4). An adapter to convert from a
DB-25 connector to an RJ-45 connector is also available from Bay Tech, upon request (Bay Tech Part
No. 25FRJ45PC-4). The 8-pin crossed modular cable is configured to operate with these adapters.
Configure serial communications parameters for the host terminal to match the DS71-MD4 module. The
modules have factory serial communications parameters of 9600 bps, 8 data bits, 1 stop bit, no parity,
XON/XOFF disabled.
Internal MODEM CONNECTION
The DS71-MD4 Host Communications Module has a Flash upgradeable 56 Kbps (V.90bis) modem
which allows two RJ-11 ports connected to standard dial-up telephone lines to be used between the Data
Switch unit and the user's Telco wall jack using a standard RJ-11 straight through cable. These ports are
in parallel and the second port is available for another Telco device using communications software, dial
the modem using the ATDT command.
IMPORTANT: The DS71-MD4 modem option has priority over the EIA-232 serial port. If a serial port
user is in configuration mode or connected to a DS74 I/O port when a modem connection is established,
the serial port user will be “booted” off, allowing the remote user to communicate with the DS unit.
External Modem Connection
Using the 25MRJ45MD-6 adapter (or other applicable adapter) and the RJ08X007 crossed cable,
connect the COM (or serial) port of the modem to the RJ-45 port labeled EIA-232 on the DS71-MD4
module. Using an RJ04X007 (RJ-11) modular cable, connect the port labeled “LINE” on the modem to
the Telco wall jack. The 25MRJ45MD-6 is not shipped with unit but is available upon request at time of
purchase.
Installation

Word Size
The word size is the measurement of the actual data bits in a transmission. Which setting you choose
depends on what information you are transferring. For example, standard ASCII has values from 0 to
127 (7 bits). Extended ASCII uses 0 to 255 (8 bits). If the data being transferred is simple text (standard
ASCII), sending 7 bits of data per packet is sufficient for communication. A packet refers to a single
byte transfer, including start/stop bits, data bits, and parity.
Select “Word Size” and the DS displays the following: Default is 8

Stop Bits
The Stop Bits are used to signal the end of communication for a single packet. Since the data is clocked
across the lines and each device has its own clock, it is possible for the two devices to become slightly
out of sync. Therefore, the stop bits not only indicate the end of transmission but also give the computers
some room for error in the clock speeds. The more bits that are used for stop bits, the greater the
lenience in synchronizing the different clocks, but the slower the data transmission rate.
Select “Stop Bits” the DS displays the following: Default is 1.
"
1 " ......1

2 " ......2
Enter Select :
Parity
Parity is a simple form of error checking used in serial communication. For even and odd parity, the
serial port will set the parity bit (the last bit after the data bits) to a value to ensure that the transmission
has an even or odd number of logic high bits. For example, if the data was 011, then for even parity, the
parity bit would be 0 to keep the number of logic high bits even. If the parity was odd, then the parity bit
would be 1, resulting in 3 logic high bits. This allows the receiving device to know the state of a bit so as
to enable the device to determine if noise is corrupting the data or if the transmitting and receiving
devices' clocks are out of sync.
With no parity selected, it's assumed that there are other forms of checking that will detect any errors in
transmission. No parity also usually means that the parity bit can be used for data, speeding up
transmission. In modem-to-modem communication, the type of parity is coordinated by the sending and
receiving modems before the transmission takes place.

Enter Select :
XON/XOFF
For a simple communication between modems three connected lines are needed: TX, Rx, and Ground.
For the data to be transmitted, both sides have to be clocking the data at the same baud rate. While this
method is sufficient for most applications, it is limited in being able to respond to problems such as the
receiver getting overloaded. This is where serial handshaking can help. XON/XOFF is software data
flow communications protocol for controlling the flow of data between Baytech and other devices.
Baytech units will send an XOFF character when it can't take any more data and when it can once again
take more data, will send an XON character to the transmitter.
Select “Xon/Xoff” the DS displays the following, Default is Off:

Disconnect Timeguard
This feature ensures reliable binary data transmission by providing a one-second “Timeguard” after the
DS-Series receives the attention character. If more data is received within the delay period, the DS
treats the character as data, not an attention character; thereby preventing unwanted port disconnection.
The Default setting is Disabled.
