8.The modem settings on the right hand side of this tab may not need to be changed, depending on the particular modem requirements of the polling software. LAVA suggests starting with them at their default values.

9.Connect the HQ Plus “Modem” port to the PC’s second COM port using the DB-9F to DB-25M serial cable.

10.Connect the HQ Plus’s Ethernet port to the store LAN on which the “Default Gateway” is located.

11.Map a TCP port nnnn (default port number is 4098) on the headquarter’s gateway to allow control and negotiation data to pass to remote units. Consult your router's documentation for this step.

12.Map a TCP port nnnn+1 (default port number is 4099) on the headquarter’s gateway to allow modem data to pass to remote units. Consult your router's documentation for this step.

13.Test the link.

See “Test that the HQ Site is Properly Set Up and Working: HQ Plus Installed” on page 26.

See “Test the End-to-End HQ-ST Link Communications: HQ and ST Installed” on page 27.

14.Attach the PC that will host the polling software. The serial port of the polling host PC should be connected to the “Modem” port of the HQ Plus. In general, it is most trouble-free to configure the serial port of the polling host PC to match the serial port of the HQ Plus, and to ensure that serial settings and connections end-to-end (from polling software to polled device) are consistent.

15.If necessary, troubleshoot the link using the troubleshooting chart: See “Troubleshooting” on page 28.
