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.

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

UNPACKING

Compare the unit and serial number of the equipment you received to the packing slip located on the
outside of the box. Inspect equipment carefully for damage that may have occurred in shipment. If there
is damage to the equipment or if materials are missing, contact BayTech technical support at 228-563-
7334 or call toll free inside the United States at 800-523-2702. At a minimum, you should receive the
following:

1. The DS71-MD4 Module.

2. Manual insert describing the location of the User’s Guide on BayTech’s website at

www.baytech.net

3. Power Cords that may be attached to the unit (if order requested detachable cords).

4. 1 ea. DE-9 (9 pin) PC com port adapter -- 9FRJ45PC (with Cisco Interface) or 9FRJ45PC-1.

5. 1 ea. RJ-45 Roll over cable -- RJ08X007.

NOTE: Keep the shipping container and packing material in the event future shipment is
required.

Power

CAUTION: This unit is intended for indoor use only. Do not install near water or expose this 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 DS-Series Data Switch unless specifically directed to; as in Appendix E of this
manual. BayTech must perform any internal changes.

CAUTION: High-voltage surges and spikes can damage this equipment. To protect from such power
surges and spikes, this unit must have a good earth ground. A grounding screw connection is located
near the power switch on the back of the unit.

CAUTION: Before removing or replacing any modules, turn off main power switch located on the DS­Series Base Unit. Communication to the DS-Series Data Switch will be disrupted while power is off.

QUICK START: DS71-MD4 Module

by Bay Technical Associates

For those Administrators who have requested the bare minimum for this type of equipment, follow these
steps exactly. If this is a new unit shipped directly from Baytech, follow the steps. If this is a previously
own unit, perform a factory reset to clear out any users and passwords still in the unit.

Serial/Modem Configuration:

1. Connect the 9FRJ45PC-4 or 9FRJ45PC-1 adapter to your PC.

2. Connect the supplied rollover flat cable RJ08X007 to the adapter and to the EIA232 serial port
on the Baytech DS71-MD4 Module.

3. Use terminal emulation software to access the unit, (i.e. Microsoft Hyper-terminal). Set the PC
serial port configuration to the following: 9600 bps, 8 data bits, 1stop bit and no parity.

4. If you get only a blinking cursor Press ‘Enter’. If still only a blinking cursor, Type 5 semi-colons
(;),The Attention Character will not echo on the screen. There is a one second delay before the
menu is displayed. You should see a menu similar to (Figure 1).

5. Select ‘C’ for the configuration menu.

6. Select the DS71-MD4 module. You should see a menu similar to (Figure 2).

7. Select the number for ‘Login Setup’ option. You should see a menu similar to (Figure 3).

8. Select the number for ‘Manage Users’ option. You should see a menu similar to (Figure 4).

9. NOTE: The ‘admin’ user can not be deleted.

10. Select ‘A’ to add user. Type the name and password at the prompts.

11. Press ‘Enter’ until get to the ‘Login Setup Menu’ (Figure 3).

12. Select option ‘Access Control’ to enable or disable the Modem and Serial Login Prompts.

13. Press ‘Enter’ until get to the ‘Login Setup Menu’ (Figure 3).

14. Select option ‘Assign User Ports’ (Figure 5).

15. Select the user and add the ports.

16. Press ‘Enter’ until you get the Configuration menu (Figure 2).

17. Select ‘Serial Port Configuration’ and set up the modem configuration.

At this point you have setup enough basic configurations to operate this Baytech unit.

Serial Setup

• Connect the 9FRJ45PC-4 adapter to the user’s computer

6

DS71-MD4 Serial host and 56k Modem

• Connect the Host Module’s EIA-232 port to the adapter via the RJ08X007 rolled flat ribbon
cable.

• Default configuration is 9600 bps, 8 data bits, 1 stop bit and no parity.

NOTE: At any time during the session you need to go to another menu, use the Attention
Character = semi-colon (;). Press the attention character key 5 consecutive times to get back to the

main status menu.
NOTE: Depending on the DS-Series model, the menus will vary according to the number of DS74

modules installed in the unit. If this is not an initial set-up and Password has already been enabled,
you are prompted to login. After logging in successfully, invoke the main menu by sending the
attention character five times (;;;;;).

NOTE: Password feature is case sensitive. (Default is user/password is root/baytech)
