Cabling and Termination
WARNING!
Connecting the module disrupts bus traffic!
Connect the module at a time when it is safe to do so.
Connect the QTS-CLX-APACS like any other IOBUS device.
Refer to the following Siemens document for details on cabling:
• "APACS+ / QUADLOG MODULRAC and Local Termination Panel
Installation and Service Instructions", SD39MODULRAC-1
Refer to section 2.10.2 of the manual shown above.
Place the QTS-CLX-APACS module at the beginning or end of the currently installed
MODULRAC racks:
1. Purchase a Siemens cable that fits the end of the MODULRAC rack that will
be used (left side of first rack or right side of last rack).
2. Cut off the end of the cable that will connect to the QTS-CLX-APACS
module and strip the cabling.
3. Wire the Bus A signals IOBUS (+) to I/O A+, IOBUS (-) to I/O A-, MRET
to MRET and MEN to MEN on the top Phoenix connector.
4. Set the shunt plug on the MODULRAC from terminate to the I/O bus
continue position and place a 120 ohm resistor between I/O A+ and I/O A-
signals on the top Phoenix connector.
Repeat steps 1 through 4 for IOBUS B cabling on the bottom Phoenix connector of the
QTS-CLX-APACS module.
Terminate both ends of the IOBUS A and B using termination provided by the
MODULRAC racks or a 120 ohm resistor attached to the physical ends of the bus, if the
QTS-CLX-APACS module is placed at the beginning or end of the bus. There should be
two and only two terminators on each bus.
The cabling is the same for monitor and master modes of the QTS-CLX-APACS.
