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 communication 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. Check that the Base Station is NOT jumpered
for Programming. JP103 should be set to N, (Normal), not P. If it is set
to P, no communication from host to Base and back will take place.
• Once you know the Base Station is communicating with the host
correctly, compare the frequency of the Base Station with the frequency
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 96-100% 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".
