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:

At a minimum, the IP Address, Subnet Mask and Gat eway must be programmed in or der to access the
unit via your network. At the “Enter Request:” prompt, type “C” followed by <cr>. The following menu

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.
