Diagnosing Wireless Modem Installation and Setup Issues
If there is no communication with the Hyper Terminal or the Gasboy PC Package, proceed as
follows:
1
Verify both modems have been properly configured and the proper cables are installed and the
connections are tested. Set the modems to the default parameters before programming.
2
Verify the coaxial connectors have been properly installed and do not short out the entire
cable.
3
For ALL STANDARD Gasboy Fuel Management systems (Standard TopKAT, 1000 series,
FleetKey and Islander II) the baud rate for all devices MUST BE 2400 BAUD. Verify the FMS
system remote port is set for 2400 baud, both modems are set for 2400 baud and the Gasboy
PC Software Package is set for 2400 baud.
Note: For the Gasboy PC TopKAT On Line software ONLY verify the TopKAT communication
port is set for 9600 baud, both modems are set for 9600 baud and the PC TopKAT On
Line software is set for 9600 baud (the TopKAT system will also have special software
for use with this software package).
4
Verify the wireless modem settings for the system and software on the site are as per the charts
provided in this manual (refer
Programming the Wireless Modems
5
If the wireless communications is intermittent, for example, if you receive a few characters or
one or 2 lines, once again check the modem programming. Ensure that other than the source
and destination address the setup is identical. Ensure that “No Ack Back” is selected and
“Preamble Bytes” is set to 266.
6
“In Manager Mode” may appear on the Gasboy PC Software package screen when subsequent
attempts to “Contact the Site” or “Polling Session” are initiated. The time period this can occur
in is approximately 5 minutes. This has been so far only noted with the standard Gasboy PC
TopKAT software. It is caused by the way the wireless modems ends the “Contact the Site” or
a “Polling Session”. To avoid this, ensure that the auto poll interval is set to 10 minutes. To
clear this state, contact the site with Hyper Terminal and then end the session with the “EX”
command.
7
If the wireless modems work properly with Hyper Terminal but report an error with the
Gasboy Software package, for example, a “No DCD signal” use the signal tests below.
