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.
