IOP to Power Adapter connection

The IOP to Power Adapter connection is made using the standard model MU-KFTAxx (the suffix "xx"
represents the length of the cable in meters) IOP to FTA cable. The maximum allowable length is 50
meters (164 feet).
For CE Compliance applications, the model MU-KFTSxx IOP to FTA cable must be used. See the
Process Manager I/O Installation manual for detailed information.

Power Adapter to FTA connection

The Power Adapter connects to the FTA through a model MU-KLXxxx (internal cabinet use) or model
MU-KLO305 (external cabinet use) cable (one per FTA). The model MU-KLXxxx cable is limited to a
maximum length of 305 meters (1000 feet), while the model MU-KLO305 cable is 305 meters in length,
the cable type (Belden YC41926) can be used in lengths of up to 2000 meters (6560 feet).
Both types of cables have four conductors in a single-twist with a single braided shield. The shield must
be connected to ground at both the Power Adapter and FTA ends of the cable. See the Process Manager
I/O Installation manual for detailed information.

Power Adapter indicators

The Power Adapter assembly has two LEDs, one for each cable, that indicate a grounded or shorted
cable. Each FTA has an LED that indicates the FTA is receiving power.
Cabling information
For more detailed information on cable selection, see the Process Manager I/O Installation manual or
the High-Performance Process Manager Planning manual.

2.10 Serial Device Interface IOP (SDI)

Introduction

Figure 11 illustrates a typical Serial Device Interface configuration. One or two Serial Device Interface
FTAs can be connected to a single Serial Device Interface IOP through the Power Adapter.
The FTA is assigned a unique FTA model number identified by the FTA's assembly tab number on the
FTA. The firmware resident in the FTA plug-in module, M1, has been preprogrammed at the factory to
accommodate the associated IOP and the selected serial communications interface type (EIA-232 or
EIA-422/485).
The Serial Device Interface FTA has both EIA-232 (RS-232) and EIA-422/485 (RS-422/485)
asynchronous serial communications interfaces, one of which is active, using either a DB-25 or a 5-
terminal compression connector, respectively.
