8. Troubleshooting Guide
We have carefully tested and found no problems in the supplied
AC301-201. However, we would like to offer suggestions for the following:
8.1 LED is Not Red
There is a power LED next to the RJ-45 connector on the AC301-201. The
LED is visible through the seam of the plastic enclosure.
Cause 1: There is no power.
Solution: Verify the AC301-201 is connected directly to the MultiTasker
and that the MultiTasker enclosure has power and is turned
on. If LED is still not on, see Cause 2.
Cause 2: The wrong cable is being used.
Solution: If there is a cable between the AC301-201 and the
MultiTasker, verify pin 9 of the cable has continuity
throughout the cable. If the LED is still not on, see Cause 3.
Cause 3: The AC301-201 is not connected to a MultiTasker.
Solution: If the AC301-201 is not connected to a MultiTasker, then the
external power adapter must be connected. Connect the power
adapter to the AC301-201. If the LED is still not on, see
Cause 4.
Cause 4: The AC301-201 has a problem.
Solution: If there is still no power, the AC301-201 may require service.
Please, call ALTINEX at [phone].
8.2 No Communication
Cause 1: The devices are incompatible.
Solution: Connect the computer directly to the destination device using
a standard RS-232 cable. If the devices communicate without
the AC301-201, the problem is with the cables or AC301-201;
see Cause 2.
Cause 2: Cable connections are wrong.
Solution 1: Verify the output of the AC301-201 is connected to the input
of the serial device.
Solution 2: Verify that the Signal Present LED on the AC301-201 is on and
red. If the LED is on and red, check the connection between
the computer and the AC301-201.
Solution 3: If the LED on the AC301-201 is red, use the DeviceInstaller as
described in the installation section. If the AC301-201 is seen
on the network and the LED is on and red, and there is still no
communication, call ALTINEX at [phone].
