Switch-to-PMS Link Testing with the

RS232 Mini-Tester

Using the RS232 Mini-Tester (see the Note on page 5), check the status of the PMS link. The leads marked with an asterisk are controlled by the switch, and the PMS controls the other leads. If any switch leads are dark, there is no connection.

!CAUTION:

After using a mini-tester to check data leads, you MUST remove the mini-tester from the connection. DO NOT leave the mini-tester in-line during actual operation.

If the link to a PMS is active, the mini-tester should show the following. The Physical Link State should be up, and the Protocol State should be up. If this is the status of the link, proceed to “Netcon and Data Module Testing” on page 219 . Otherwise, look at the other results in this section.

If the link is idle, the mini-tester may show the following. The Physical Link State will be down, and the Protocol State will be down. Possible causes may be that the switch or PMS are not administered correctly, or the PMS software is not running.
