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 add a Relay.
I'm not getting the distance I need...
To maximize range, the Base Stations and Relays should be located:
1. At the center of the area of intended coverage, and
2. 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
