DS62-Network, DS62-MD4 Network/Modem Host Module
6
Connection Description
BayTech's host communication module provides an interface that controls user access to the DS Series
data switch and other DS Series connected modules.
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.
Internal MODEM CONNECTION
A Flash upgradeable 56 Kbps (V.90bis) modem allows standard dial-up telephone lines to be used
between the Data Switch installation and the user's location.
IMPORTANT: The DS62-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. Using the RJ04X007 (RJ-11) modular cable, connect to “LINE” on the DS62-MD4 module to
the Telco wall jack. Using communications software, dial the modem using the ATDT command.
10/100 BASE-T NETWORK PORT CONNECTION
Using a straight 10/100 Base-T cable, connect the RJ-45 port labeled ETHERNET on the HOST
module to an RJ-45 port on the network hub. The LINK (link integrity) LED, located on the front
panel of the HOST, illuminates when a good connection is established between the HOST and the hub.
