Performing a Self-Test

When the MediaChecker is on, it periodically tests some

of its internal circuits. If a problem is detected, the

MediaChecker displays the following message:

aan16f.eps

You can perform a more thorough self-test on DeviceNet,

DH+/RIO, and Ethernet functions as follows:

1. With the MediaChecker off, press and hold A

while turning the rotary switch to TEST.

2. Press E until “SELF-TEST?” is displayed.

3. Press C or D to select “YES”.

Important: To exit without performing a self-test, either

press A, or ensure that the second line is

displaying “NO” and press E to move to

the next setup selection.

4. Press E to activate the self-test program.

You will be prompted to install the Cable ID. There

are two ways to install the Cable ID, each with

different results:

• To run a self-test on DeviceNet and DH+/RIO

functions, connect a DB9-to-Mini/Micro male

adapter in series with a Mini/Micro female-to-DB 9

adapter. Use this series combination to connect

between the DB9 connector on the Cable ID and

the DB9 connector on the MediaChecker.
