Worth Data RF Terminal 7000 - Manual (Page 74)

above.
• Two bases on the same channel are big trouble.
Sometimes you get an error message and after checking, everything on the Base seems to be set OK. Drop
power on the suspect Base and try signing in again. If you get the same message, there is another Base
answering which should not be on the same channel.
Troubleshooting specific problems
I can’t communicate at all...
• First, check the communication link from the Base Station to the 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 echoes it 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.
• 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. 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 at greater than 10 feet. 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".
My response time is poor...
• First, do Site Test 50 feet from the Station. If it's not 90+%, the Radio in the Terminal or the Base Station is
the problem.
• Second, run one of the demo programs. If the demo runs fast, it is your program that is slow.
• If you have good response time everywhere but on the outer fringe area you may need to relocate your Base
Station.
I'm not getting the distance I need...
To maximize range, the Base Station and Relay(s) should be located:
• At the center of the area of intended coverage, and
• As high as possible - mounted on the ceiling of a room with the antenna pointing downward works the best.
Sometimes just raising the Base Station to 12 feet will dramatically increase the distance, especially in
warehouses or grocery stores with tall shelving. A Base Station mounted on the wall with the antenna parallel
