Hardware Setup
Setup Procedure:
1. Use an RS-232 cable to connect the DB25
connector (J1) on the modem to a PC serial
Port (typically COM1).
2. Connect the RJ11 connector to a phone line.
3. Connect external power +5VDC to the
power jack or via alternate DB25 pins 10 &
7. See the Power Connections section to
ensure correct connector polarity and power
select switch position.
Hyper Terminal Setup
The modem can be tested as a standard serial
data modem by connecting it to a personal computer or other data terminal equipment (DTE).
Any standard terminal program such as HyperTerminal o PCComm running on a PC will communicate with the modem.
Power Connections
There are two optional methods of supplying
power to the modem. Use the power connector
or via the RS-232 cable. A slide switch on the
side of the case selects which is used.
Included with each modem is the mating connector for the input power. Connect the external
5 VDC power source to the supplied connector
with attention to the +/- polarity of the voltage
source.
CAUTION: NOTE THE POLARITY ON THE
CONNECTOR LABEL.
