Appendix D. TROUBLESHOOTING

This section covers suggestions to assist the user in troubleshooting the MENCAP 50. If
the suggestions in this section do not result in correct operation of the unit, please contact
Comtech EF Data Customer Support for further assistance.

SYMPTOM: MENCAP 50 does not power up

When the MENCAP 50 power is on, the blue

PWR

LED should be illuminated. If

this LED is not illuminated, ensure the power supply is plugged in and tightly
connected to the MENCAP 50.


SYMPTOM: Cannot communicate with the MENCAP 50 using a terminal/PC

The user can communicate with the MENCAP 50 using a CEFD-supplied terminal
cable and a communications port on a desktop PC or notebook PC.

Ensure the terminal cable is connected to the PC’s communications port and
the

TERM

port on the MENCAP 50.

The communication program (HyperTerminal or TeraTerminal) should be
configured as 38,400 BAUD rate, 8 Data bits and No Parity and 1 Stop bit –
commonly referred to as 38,400/8/N/1.

Flow control should also be disabled.


SYMPTOM: Cannot get

E-LINK LED to illuminate on the MENCAP 50

The most common mistake is using an “Ethernet Crossover Cable” instead of a
standard “patch cord” or “straight-through cable.” A crossover cable should only
be used if connecting the MENCAP 50 directly to a PC. Otherwise, a patch cord
to an Ethernet concentrator (Hub) or switch should be used.


SYMPTOM: Cannot ping the MENCAP 50

If the

E-LINK

LED is illuminated but the user cannot ping the MENCAP 50, the

most likely causes are incorrect settings for the IP address or subnet mask.
