Troubleshooting

Introduction

Troubleshooting CallPilot Mini problems involves determining the symptoms and diagnosing the
cause of the problem.
A problem can be the result of more than one component failure. Diagnosing a CallPilot Mini
problem involves isolating the cause, and determining whether the malfunction involves a failed
hardware component or the CallPilot Mini software configuration.
Important: After you have determined the cause of the problem, and corrected the problem by
replacing a component or changing the software configuration parameters, you must test the
CallPilot Mini.

Diagnosing problems

A malfunctioning CallPilot Minican be caused by a faulty component or the CallPilot Mini
software configuration. The following sections describe the symptoms that occur when CallPilot
Mini malfunctions. The symptoms are described first, followed by the procedures to confirm and
correct the problem.

The RS-232 terminal cannot communicate with CallPilot Mini

Communication problems appear as garbled text or a blank screen. You need to determine if the
problem is a communication problem, or if CallPilot Mini is not working at all.
1 Ensure the RS-232 terminal communication parameters are set to 9600 baud/ 8 data bits/1 stop
bit/no parity/no flow control. For instructions about setting these parameters, refer to the
manual supplied with the terminal.
2 Check the RS-232 cable. Ensure it is connected to the serial port on CallPilot Mini and to the
serial port on the terminal.
3 Reset the terminal (or terminal emulation software).
4
On the RS-232 cable, use a multi-tester to check the continuity of the pins:
• pin 2 - pin 2
• pin 3 - pin 3
• pin 7 - pin 7
If any check fails, replace the cable.
5 Use a different terminal.
6 If there is still a problem, reboot the CallPilot Mini system. If there is no improvement call
your support line.
