INSTALLATION
Optionally Modify Jumper Settings
Internal PSM-8E jumpers allow selection among
three RJ-45 pin configurations (4 & 5, 3 & 6, 1 & 2)
and the DB-25 connection. All PSM-8Es jumpers
are factory configured and the factory setting is
circled on an identification label located at the rear
of the PSM-8E. If required at the installation site,
these factory settings can be changed.
NOTE: The DB-25 and the RJ-45 jumper configurations are mutually
exclusive. If any of the three RJ-45 options is selected, the DB-25 option is
deselected. If the DB-25 option is selected, the RJ-45 options are deselected.
WARNING: Remove AC line cord from power source before modifying
jumper settings. Failure to observe this warning could result in personal
injury or death.
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when modifying jumper settings. Failure to observe this caution
could result in damage to, and subsequent failure of, the PSM-8E.
To modify the PSM-8E jumper settings:
1.
Remove PSM-8E top cover.
•
Remove and retain two (2) top cover screws located on rear
panel.
•
Gently slide top cover back one inch.
•
Carefully tilt top cover up.
2.
Locate eight (8) sets of jumpers positioned behind the eight (8) RJ-45
connectors.
3.
Using small screwdriver or similar device and referring to drawing
below, reconfigure jumpers as required.
NOTE: JUMPERS SETTINGS FOR ALL EIGHT (8) SETS OF JUMPERS
MUST BE IDENTICAL.
4.
Replace PSM-8E top cover:
•
Carefully tilt top cover down.
•
Slide top cover forward to align against bottom cover.
•
Install two (2) retained top cover screws.
5.
Do devices interfere with each other?
YES
•
Is there one and only one host-polling group per PSM-8E polling
group?
•
Do all devices on star segments have unique addresses?
•
Are all devices properly terminated?
•
Contact Technical Support: (800) 260-1312.
NO
•
Continue at step 6.
6.
Are devices able to operate in Express mode?
NO
Note that the controller may have down-shifted to 1 Mb/s due to
errors during installation. If this is the case, the controller will wait
approximately one hour and then retry the Express mode.
•
Are the host AND the device capable of Express mode?
•
Do all inter-connecting components support the Express mode?
•
Are all devices on the port Express ready?
•
Are all cable distances within the Express specification?
YES
•
Continue at step 7.
7.
Do Express LEDs flash?
YES
Note that if there are fewer than seven devices, the flashing Express
LED is normal.
NO
•
Continue at step 8.
8.
Are Express LEDs ON without data activity?
YES
Note that If the host is disconnected during an Express connection,
the Express LED remains on.
