DS72 HOST MODULE OWNER’S MANUAL

INTRODUCTION TO THE DS72 HOST MODULE

INTRODUCTION TO THE DS72 NETWORK INTERFACE
MODULE

The DS72 network interface module is a primary user interface for use with the BayTech DS-Series and
DS-RPC units. The DS72 allows network users operating on a device using a TCP/IP stack with an
ethernet connect ion, to access the main DS units, serial I/O modules, and (in the case o f the DS-RP C)
remote power switches. It also allows remote access via external modem to the serial port. This makes the
DS72 an extremely versatile module, covering most applications.

DS72 QUICK START

DS72 QUICK START

This section describes the basic steps required to set up and configure your DS72. If you need to
acquaint yourself further with the setup, configuration, and operations, see “Detailed Operations and
Configuration” beginning on page 8.

GETTING STARTED

Befo re the DS72 can be us ed within a networ k, ther e are a few para meter s w hich must be configu red.

For an initial setup, connect the serial port of your computer to the RJ-45 port labeled “EIA-232” on t he
DS72 module using the 9FRJ45PC-4 adapter and the RJ08X007 (8 pin crossed) cable.

With standard serial communications software or a terminal, set serial communications parameters to
9600 bps, 8 data bits, 1 stop bit, and no parity. This will allow direct communicat ions with the DS72
module. Appl y powe r to the DS -Series unit. The following main menu w ill appear:

INSTALLATION

INSTALLATION

UNPACKING

Compare the unit and serial number of the equipment you rece ived to the packing slip located on the
outside of the box. Inspect equ ipment carefully for damage that may have occurred in shipment . If t here
is damage to the equipment or if mater ials are missing, contact Ba yTech customer service at 228-467­8231 or call toll free inside the United States at 800-523-2702.

NOTE:

Keep the shipping container and packing material in the event future shipment is

required.

PREPARING THE INST ALLATION SITE

The installation area shou ld be clean and free of extre me temperat ur es and humidit y.

POWER

CAUTION:

This unit is int ende d for indoo r use only. D o not inst all nea r wat er or expo se t his
unit to moisture. To prevent heat buildup, do not coil the power cord when in use. Do not use
extension cords. Do not attempt to make any internal changes to the power source. Do not
attempt to modify any portion or component of a DS72 module unless specifically directed by
BayTech p e rso nnel. BayT ech will pe rfo rm mos t inte rnal changes.

CAUTION:

Before removing or replacing any modules, turn off main power switch locat ed on
the DS-Series Base Unit. Communication to the DS-Series Data Switch will be disrupt ed while
power is off.

CABLING

RJ-45 CABLES AND ADAPTERS

DS72 HOST MODULE OWNER’S MANUAL

CABLING

IMPORTANT:

The DS72 network interface module has 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; t herefore an adapter is
provided with this unit to convert from a DE-9 connector to an RJ-45 co nnector ( Bay Tech Part
No. 9FRJ45PC-4). An adapter to convert from a DB-25 co nnecto r 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.

CAUTION:

All power should be removed from the DS72 unit prior to removing or installing

cables.

The DS72 Et hernet co nnect ion requ ires a straig ht cable betwee n the et hernet port of the DS 72 modu le a nd
the network hu b. The “LINK” light will lig ht gr ee n when a good link has been establis hed.

DETAILED OPERATION AND CONFIGURATION

The following section, “Detailed Operation and Configuration,” provides a detailed approach to
accessing, operating, and configuring the DS72 network interface module.

attention character five times (;;;;;).

Another method of selecting devices and operatingthe DS-Series and DS
RPC is the ASCII character string metho d. To select a device located on
a peripheral Port, type $BTm,p where m is the module and p is the port.
To configure a module, type $BT and the module number followed by

DS72 HOST MODULE OWNER’S MANUAL

DETAILED OPERATION AND CONFIGURATION

<cr>, then $CONFIG followed by <cr>. This will allow access to the
configuration menu for that module. Once configuration is complete, type
X for “Exit” followed by <cr>. To access the main menu, type the
attention charact er five times.

NOTE:

NOTE:

You must exit main menu to send ASCII char acter string commands.

While operating using the ASCII Character String method, consider placing the DS-

Series in binary mode.

Binary Mode

Te rm ina te Bin ary
Mode

If binary data containing the port select code is sent to a module, the DS­Series may interpret the data as a command to change port s. Binary mode
prevents such an occurrence by placing the DS-Series in a mode which
does not look at the data. This provides a reliable binary data transmission.
However, before a connection can be made to another port, the binary
mo de must be termi na ted.

Place the port in binary mode by sending the port select code, a capital B,
and a carriage return

($BTB).

For example, if using the default Port

Select Code ($BT), place Module 2, Port 1 in binary mode by typing

$BT2,1<cr>$BTB<cr>.

From the terminal emulation software, send a BR EAK condition

command to terminate binary mode. You may have to consult the
software users’ manual for the specific BREAK condition command for
the emulation software you are using. For example, the BREAK condition
command for PROCOMM PLUS is “Alt B.”

NOTE:

The break length for emulation software is progra mmed within that so ftware. The break
length for a TELNET session is programmed within the BayTech firmware. This procedure is
discussed on page 20.
