FCC REQUIREMENTS FOR THE V93A HOST
COMMUNICATION MODEM MODULE

1. The Federal Communications Commission (FCC) has established
rules which permit this device to be directly connected to the
telephone network. Standardized jacks are used for these
connections. This equipment should not be used on party lines or coin
lines.

2. If this device is malfunctioning, it may also be causing harm to the
telephone network; this device should be disconnected until the source
of the problem can be determined and until repair has been made. If
this is not done, the telephone company may temporarily disconnect
service.

3. The telephone company may make changes in its technical operations
and procedures; if such changes affect the compatibility or use of this
device, the telephone company is required to give adequate notice of
the changes. You will be advised of your right to file a complaint with
the FCC.

4. If the telephone company requests information on what equipment is
connected to their lines, inform them of:

a. The telephone number this unit is connected to
b. The ringer equivalence number
c. The USOC jack required: RJ-11
d. The FCC Registration Number

Items 'b' and 'd' are indicated on the label.

3

The ringer equivalence number (REN) is used to determine how many

devices can be connected to your telephone line. In most areas, the sum of
the RENs of all devices on any one line should not exceed five (5.0). If too
many devices are attached, they may not ring properly.
In the event of equipment malfunction, all repairs should be performed by our
Company or an authorized agent. It is the responsibility of users requiring
service to report the need for service to our Company or to one of our
authorized agents. Service can be obtained at:

1 GENERAL INFORMATION

The V93A Host Communication Modem Module is the remote user interface
to the BayTech M Series DAC (Data Acquisition and Control) units. This
module features a V.32bis/V.42bis internal modem and allows a remote host
terminal to connect and issue specific configuration or data commands to the
various I/O modules or the M Series DAC unit main board. Multiple V93A
modules can be installed in a M Series chassis allowing I/O modules to send
data to specific V93A modules. Please see the M Series DAC Owner’s
Manual for more information on the available types of I/O modules.

IMPORTANT: The first module slot of the M Series DAC base unit must
be occupied by a host module.

4 CABLES & ADAPTERS

The V93A modem has two modular connectors for device selection and
configuration. One connector is for connection to a dial-up line. The other
connector is used to communicate with an EIA-232 port.

.1 EIA-232 CONNECTION

Connect the eight pin modular cable(RJ-45) to the port labeled EIA-232 on
the V93A. Connect the DB9 adapter to the serial port of your PC or terminal
and then connect the other end of the cable to the RJ-45 side of the adapter.
Use adapter BayTech part number 9FRJ45PC-3 and cable, BayTech part
number RJ08X007 that come with the RPC.
