A1.8 Connecting to a Modem

Setting and Sample Program when Connecting to a Modem
We describe here how to connect to an external modem and send a message to a
beeper. Sending a message to a beeper requires programming in ladder or BASIC.
The program writes the telephone number of the beeper and the message to be
transmitted to the internal registers of this module, turns on the Dial Request relay to
start auto-dialing. Once connected, it turns on the Request to Send output relay (internal
dummy relay of this module) to start transmission.
1. Set the switches
Turn on (“Yes”) bit 8 of SW3 (External Modem: Yes/No) .
Set the other switches to default.
2. Connect to the modem using a straight cable.
If the cable provided with the modem is female and does not match, use a gender
changer.
3. A sample ladder program is shown below.
Transmit 0 for external transmission. The beeper number is 1234-5678-9999.
The send message is “LC11-1F” in the sample program.
If I1001 is turned on, the program dials the beeper and sends a message.
