Setting up a dialup network requires two (2) modems – one connected to a serial port on the Server and one
connected to the first IRC2000 board at the remote site.
Remote Site Modem:
1. Set DIP Switches 1 through 5 to define the IRC2000‟s address.
2. RBH recommends a U.S.Robotics
®
external Sportster modems and a baud rate of 9600.
3. Make any DIPswitch settings on your modem as per your modem manual and the Integra32™ hardware manual.
Data Terminal Ready (DTR) or (TR)
These settings on the recommended modem would mean that all modem DIPswitches (1, 3, 4, 7, and 8)
were down, except switches 2, 5, & 6, which will be up.
Note: PC side modem will not work with above DIP switches settings. PC side modem has to be set to default
settings (3, 5, 8)
4. Check the telephone line for dial tone and connect the phone cord to the modem.
5. Power up the modem and check the front panel lights to verify that the AA, TR, and CD settings are correct as
per the above table.
6. Plug in the IRC2000 to Modem cable (See the Hardware Manual for pin outs)
7. Power up the IRC2000. The IRC2000 will automatically reset the modem and download the initialization string
required to receive a call from the Server modem.
