INTRODUCTION TO THE DATA SWITCH
(DS) SERIES

BayTech’s DS-Series Data Switch provides a single dialup or EIA-232
gateway to multiple EIA-232 devices. Used for accessing remote
equipment or simply switching between multiple ports, the DS-Series Data
Switch provides a full duplex connection between the host and up to 32
peripherals. In a typical application, the host module connects to a local
or remote computer, and the peripheral port modules connect to devices
such as routers, hubs, servers, and Data Service Units (DSU’s). The
DS-Series Data Switch is also compatible with other BayTech products
including the Remote Power Control (RPC) unit.

The DS-Series Data Switch is available in three chassis sizes. The DS3,
DS6, and DS9 have 3, 6, and 9 expansion slots respectively, providing a
maximum of 8, 20, or 32 device connections.

Table 1 provides a brief description of user programmable features
available for the DS-Series Data Switch modules. Look for a detailed
description of each feature at the page number given.

MJ-45 CABLES AND ADAPTERS

IMPORTANT: The DS-Series host communications modules

have an MJ-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 MJ-45
connections; therefore an adapter is provided with this unit to
convert from a DE-9 connector to an MJ-45 connector (Bay Tech
Part No. 9FMJ45PC-4). An adapter to convert from a DB-25
connector to an MJ-45 connector is also available from Bay Tech,
upon request (Bay Tech Part No. 25FMJ45PC-4). The 8-pin
crossed modular cable is configured to operate with these adapters.

CAUTION: All power should be removed from the DS Series
unit prior to removing or installing cables.

Figures 1 and 2 provide visual representation of an MJ-45 receptacle and
plug; pin number assignments are given in Table 2.

DETAILED OPERATION AND
CONFIGURATION

The following section, “Detailed Operation and Configuration,” provides a
detailed approach to accessing, operating, and configuring the DS-Series.

NOTE: It is important that you type all commands correctly.
Any combination of wrong entries results in an error message.

CONNECTING TO THE DS-SERIES DATA SWITCH

EIA-232 SERIAL The DS71 Host Module has an MJ-45 port
CONNECTION for connecting to a local EIA-232 device,

such as a computer terminal or external
modem. Most serial computers do not have
MJ-45 connections; therefore, an adapter is
provided with this unit to convert from a
DE-9 connector to an MJ-45 connector
(BayTech Part No. 9FMJ45PC-4). If you
are connecting to a modem, use a modem
adapter (BayTech Part No. 25MMJ45MD-6)
and an MJ08X007 8-pin crossed modular
cable.

BayTech also manufactures a
computer/terminal adapter (BayTech Part
No. 25FMJ45PC-4) for converting from a
DB-25 connector to an MJ-45 connector.

If you require a different adapter than the
one supplied with this unit, contact
BayTech’s Applications Engineers.

Using the 9FMJ45PC-4 adapter (or other
adapter) and the MJ08X007 crossed
modular cable, connect the serial port of
your computer to the MJ-45 port labeled
EIA-232 on the DS71 or DS71-MD2

module.
Load serial port communications software.
Configure serial communications parameters
for the host terminal to match the DS71 or
DS71-MD2 module. The DS71 or DS71­MD2 modules have factory serial
communications parameters of 9600 bps, 8
data bits, 1 stop bit, no parity, XON/XOFF
disabled.

INTERNAL MODEM The DS71-MD2 has a 14.4K bps internal
CONNECTION modem for remote access.
(DS71-MD2 ONLY)

IMPORTANT: The DS71-MD2 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.

Using the RJ04X007 (RJ-11) modular cable ,
connect either port labeled “LINE” on the
DS71-MD2 module to the telco wall jack.
Using communications software, dial the
modem using the ATDT command .

NOTE: Both “LINE” ports are active and either can be used.
The second “LINE” port is available for growth.

EXTERNAL MODEM Using the 25MMJ45MD-6 adapter (or other
CONNECTION applicable adapter) and the MJ08X007

crossed cable, connect the COM (or serial)
port of the modem to the MJ-45 port labeled
EIA-232 on the DS71 or DS71-MD2
module. Using an RJ04X007 (RJ-11)
modular cable, connect the port labeled
“LINE” on the modem to the telco wall jack.
Using communications software package,

10BASE-T NETWORK Using a straight 10Base-T cable, connect the
PORT CONNECTION MJ-45 port labeled ETHERNET on the

DS73TP module to an MJ-45 port on the
network hub. The LINK (link integrity)
LED, located on the front panel of the

21

Binary Mode If binary data containing the port select code

is sent to a module, the DS-Series may
interpret the data as a command to change
ports. 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 mode must be
terminated.

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>.

Terminate Binary From the terminal emulation software, send
Mode a BREAK 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.”

DISCONNECT TIME When using the Attention Character Method,
GUARD it is possible for the same character being

sent as data from another device to be
interpreted by the DS series module as the
attention character. This could result in
unwanted port disconnection. If enabled,
the Disconnect Time Guard feature provides
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-Series treats the
character as data, not an attention character;
thereby preventing unwanted port
disconnection. Default Disconnect Time

Guard is disabled.

EPROM UPGRADE

If you receive an EPROM upgrade, you will need a screwdriver and an IC
DIP extractor or a pair of curved needle-nose pliers

1. Remove all power from the unit by placing the power switch to the 0
position and disconnecting the power supply from the outlet.

2. Remove the appropriate module by loosening the 2 straight slotted
screws that attach the module to the chassis, then pull the module out.

3. Refer to Appendix D (DS71 or DS71-MD2 module Mechanical
Layouts); locate socket U2.

4. Remove existing EPROM from socket U2 with IC extractor or
needle-nose pliers. Gradually loosen each side of the chip, alternating
pliers from side to side being careful not to bend chip pins.

5. Install the EPROM into socket U2. The EPROM is notched; the notch on
the EPROM should line up with the notch on the socket. Seat each pin
securely in its socket being careful not to bend chip pins.

6. By moving a hardware jumper, reset the DS71 or DS71-MD2 module to
default configuration status.

a. Refer to Appendix D (DS71 or DS71-MD2 module Mechanical

Layouts), locate Jumper JP4.

b. Jumper JP4 connects the two pins that are closest to the aluminum

face plate on the module. These pins are labeled “RUN”.

c. Connect the two pins that are further from the face plate of the

module by moving Jumper JP4. These pins are labeled “TEST”.

DS-SERIES OWNER’S MANUAL

APPENDIX E

d. Replace the module (ensure the screws are fastened to connect chassis

ground) and return power to the unit. The LEDs will illuminate
during the self test sequence. When the LED lights go off, the unit has
reset.

e. Remove power from the unit once more. Remove the module,

and move Jumper JP4 back to the two pins that are closest to the
aluminum face plate on the module (RUN). Upon initiation of power,
the DS71 or DS71-MD2 module will resume default configurations.
Refer to Table 1 on page 2.

7. Restore power to the unit. The EPROM upgrade is complete.
