Diagnosing Gasboy System Serial to LAN Connections
In order to diagnose some of the serial to LAN issues, the following items are needed:
1
Laptop or test PC with an Ethernet and serial COM port that can run HyperTerminal and/or Telnet (or
something similar). Telnet is included with most Windows operating systems.
1
9 to 25 modem cable (Q13240-09 or equivalent)
1
CAT-5 crossover cable (Q13850-C06 or equivalent)
1
C04532 RS-232 modem cable
1
AC terminal strip
It may also be necessary to have two more Serial to LAN adapters, a Gasboy Short Haul
Modem, a null modem adapter, and 25-pin D-type gender adapters.
If you have the IP and port address from the Network Administrator (or other IT personnel),
use those values for testing any issues.
1
To verify the communication to Gasboy system (for example, Gasboy Short Haul Modem or
Direct Connect), set up a HyperTerminal session (or other terminal emulation software
session) with the following parameters:
Baud
Set to match the Gasboy system port being used (normally 9600
baud).
Data bits
8
Parity
None
Stop Bits
1
Flow Control
None or Xon/Xoff
Emulation
auto
Connect using
COM port on PC
2
Use the 9 to 25-pin modem cable (Q13240 09 that was supplied with the kit), connect test PC
COM Port to SHM or termination box or D-type connector (you will need a null modem
adapter and possibly a gender adapter to connect to the D-type connector, see
) and verify you can sign on and run system commands. You must be able to
communicate with the system at this level before going forward.
