Troubleshooting Terminal, Printer and Serial Device Connections - Edition 4 (32022-90030)

2 Troubleshooting Procedures
Recall that, in this manual, “serial device” refers to any of the following
DTC connected devices:
• Terminals.
• Serial printers.
• PCs (in terminal emulation mode).
• Plotters.
Serial device problems can be caused by the system, by application
software, by faults within the device or DTC connections, or by the LAN
hardware. Procedures for troubleshooting all possible faults are beyond
the scope of this manual. Instead, the manual focuses on checking for
simple faults at the device and testing the DTC and DTC-terminal
connections.
