Troubleshooting Communications
Use the following checklist if communication cannot be established with the PAC2.
1. Verify the correct cables are being used. An RS-232 connection requires a
straight-through serial cable. That is, pin 1 on one end is connected to pin 1
on the other end; pin 2 connects to pin 2 and so on. With a TCP/IP
connection, a CAT5 cable with 8-pin RJ-45 connectors must be used.
2. With a serial connection, verify the correct COM port on the PC has been
selected. Some computers have more than one COM port; some may be
internal (for example, for a modem). Consult the manufacturer’s
documentation for further information about the COM ports on the PC.
