Worth Data 7100 RF Terminal Series Owner's Manual page 34

If you are configuring a Relay, the first Relay should be configured as Relay ID "0", which is the default. If you have more than
one Relay, then select the desired Relay ID for this unit.
You can enable a Security Code for either a Base or a Relay. The Security Code needs to be three characters and when enabled, requires
anyone wanting to make a change to the Base or Relay to enter this 3-character code.
"Xon/Xoff Sensitive" should be checked ONLY if your system has XON/XOFF specified for handshaking on the serial port in
use. Typically in Windows, handshaking will be set to "None" and you should leave this setting unchecked. See "Addressing a
Terminal not Signed In" and "Base Station Initialized Message" in Chapter 6 for details.
Once you have made any and all changes, click on the "Send Settings" button. Your Base or Relay is now configured!
Testing the RF link between base station and host
Use the following command to test the transmission of data from host to Base and back again to the host:
@@*Edataaaaaaaa<EOT>
where dataaaaaaaa is any string of data, terminated by EOT. This string should be sent from the host to the Base Station. If the
data is received by the Base, it is echoed back to the host in the format:
dataaaaaaaa<CR>
where dataaaaaaaa is the data string from the original transmission, terminated by a CR (ASCII 13). This test verifies communi-
cation in both directions (host to Base, Base to host).

If the data isn't echoed back, either your host COM port or the Base Station has a problem.

Once you know the Base Station is communicating with the host correctly, compare the channel of the Base Station with
the channel of the Terminal. Use Site Testing to check the communication of the Terminal to the Base and back. Stay close,
make sure no other Terminals are in use, and go to Site Test mode on the Terminal. You should get 90-100% on first try. If
you don't, it's a good chance your radios need repair. Call Worth Data for an RMA.
If you are using PICK or UNIX as your operating system, make sure the Base Station is set to "XON/XOFF Sensitive".
