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 or ProComm running on a PC will communicate with the modem.

AT Commands

AT refers to the command prefix (attention sequence) that precedes each command to the

modem. With the exception of A/ all commands must be preceded by AT and end with a carriage

return <return>. Some useful AT commands commonly used are:

The A/ command instructs the modem to repeat the last command line. A command line

termination character is not required for the execution of this command (that is, the command is

executed as soon as the slash is typed).
