What is the Resize
Command? What does it
do? Why is it useful?

This command is issued to set the Chain Size. The Chain size is the
maximum number of P2ZCIMs allowed in the chain. Smaller chains
have better power status reporting. The Resize command can also be
used to optimize the database memory in Paragon systems. See the
Specifications section to see how this command is issued. The user
must increase the chain size if more P2ZCIMs are added to the chain.
Example: Suppose you have eight new P2ZCIMs and you attach them to
the Paragon UMT. The user will see 42 Database entries for the chain.
This could be a wasteful use of Database memory for users who only
wish to have a maximum of eight P2ZCIMs on that chain. The resize
command can be sent to set the chain to eight P2ZCIMs. Now the user
will only see eight database entries for that chain. Note: If more
P2ZCIMs need to be added to the chain, the chain will need to be
resized.

What is the Refresh
Command? What does it
do? Why is it useful?

This command is issued to reset the Communication Addresses to the
factory default. The Master P2ZCIM then reassigns the Communication
Addresses sequentially. The communication address order will be
different after using this command. This can also be useful for fixing a
problem when all other methods fail. See the Specifications section to
see how this command is issued.
Example: Suppose a user has a P2ZCIM that appears as Channel 42 in
the Paragon User Station Channel view. The user disconnects this
P2ZCIM from the chain and wishes to add it to another chain. When
looking at the Channel view, the user notices that the P2ZCIM still
appears as Channel 42 on the new chain. The user then issues the
Refresh command so that the P2ZCIMs reorder sequentially.

How can I check the CIM
firmware version?

Switch to the CIM. Open up a text window (WordPad, Text Pad, Note
Pad, etc.). Press and hold “Left Control.” Then press “Num Lock.” The
Firmware version will be printed out. If it is a USB CIM, you will be able
to choose the keyboard type. To exit this mode press “ESC” (escape
key).

My P2ZCIM chain
disappeared when I turned
off a computer and it
reappeared 20 seconds
later. What happened?

The Master P2ZCIM may have been turned off. If this is the case then a
new P2ZCIM became the Master and the database had to be rebuilt.
This is normal operation.

I only see some of my
P2ZCIMs. What is going
on?

This can happen for a variety of reasons. Listed below are some of the
common techniques for fixing this issue.

1. Wait a couple of minutes. The Master P2ZCIM may be

temporarily confused due to Resizing, Communication Address
conflicts, Multiple Masters, etc.

2. Make sure that all the P2ZCIMs in the chain have power.
3. Check all the cables.
4. Make sure the terminator is in place.
5. Are there any P2ZCIMs in the chain that do not have

Communication Addresses? P2ZCIMs without Communication
addresses will beep once every minute. The LED will flash on
and off rapidly. If this is the case, check the Chain Size. Resize
if necessary.

If none of these techniques work, try refreshing the P2ZCIM chain.
