Product Line

TAC IA Series

Environment

• ENC-520-2
• ENC-410-1

Cause

Dialup modem setup.

Resolution

1. In the Station, under Platform Services, go to the SerialPortService
2. In the Port Config field, change the setting to Com1_232_com2_modem. Save this setting.
3. Now, go to the Platform of the ENC, and go to Dialup Configuration
4. The Init String should look something like this:
   ATE0S0=0Q0V1X4&D2&K3\N3%C2&C1&Q5W2
   Change the 0 just after the "=" sign to a 2.  This will tell the modem to answer on the second ring.
5. Make sure that the Port field says COM2
6. Check the Enabled box next to Listen for Calls
7. In the Local IP Address field, type in the IP address of the ENC
8. In the Remote IP Address field, type in an unused IP address on the same subnet as the ENC.
9. Type in a User Name (eg. invensys)
10. Type in a password (eg. niagara)
11. Save your changes, then click the Start button at the bottom of the page.  This will start up the dialup daemon.
12. Re-boot the station in Station Director.
