PowerStar™ IV
Connecting Link Cable to Host
Connect the AS/400, Sys36, or 5x94 remote controller host to
the PowerStar IV using either twisted pair, twinax or fiber cable.
NOTE: All cable lengths must be greater than 25 feet (7.6 meters).
Connecting Twisted Pair Link Cable
When installing twisted pair cable, attach a balun to the AS/400™ or
S/3x twinax port, then attach the twisted pair cable between the balun
and the RJ Link connector on the PowerStar IV.
CAUTION: Do NOT use a balun to connect twisted pair cable to
twinax cable. A mid-link media change may degrade the signal and
result in data loss.
NOTE: When twisted pair cable is used, compatible baluns must be
selected according to the chart on page 4, the RJ-11 or RJ-45
connector pin settings must be configured as shown on page 8, and
the polarity switch must be set as shown on page 18.
To connect link cable to PowerStar™ IV link connectors:
1. Locate or build twisted pair cables that conform to
specifications on page 23 and to conditions noted above, with
minimum length of 25 feet (7.6 meters) and with male RJ-11
or RJ-45 plug connectors installed at both cable ends.
2. Connect male RJ-11 or RJ-45 plug connector at one end of
cable to a Link port on the PowerStar™ IV RJ-11 or RJ-45 jack
connector.
3. Connect balun to the twinax port on the host computer.
4. Connect male RJ-11 or RJ-45 plug connector at other end of
cable to balun installed on the host in step 3.
