Installation

Important: This module mounts on a special 1203 terminal base unit and should

not be used with any other flex base. You can remove and insert modules under power. However, removal may cause the attached SCANport device(s) to fault.

To mount this module, you need to:

FLEX I/O SCANportt Module Installation Instructions

1. Rotate keyswitch (2) on terminal base unit (3) clockwise to

position 1 as required for this type of module.

2. Make certain the flexbus connector (7) is pushed all the way to

the left to connect with the neighboring terminal base/adapter.

You cannot install the module unless the connector is fully extended.

3. Make sure that the pins on the bottom of the module are straight

so they will align properly with the connector in the terminal base unit.

4. Position the module (6) with its alignment bar (5) aligned with

the groove (4) on the terminal base.

5. Press firmly and evenly to seat the module in the terminal base

unit. The module is seated when the latching mechanism (1) is locked into the module.

6. Repeat the above steps to install the next module in its terminal

base unit.

ATTENTION: The 1203–FM1 may require up to twice the adapter

power supply current of standard flex modules. When installing flex

modules, you can use a maximum of four 1203–FM1 modules with any flex adapter. As a general rule, each 1203–FM1 requires the power capacity of two of the standard flex modules, so you cannot install as many standard modules as you normally would when using the 1203–FM1. Refer to the following chart to determine the number of 1203 and standard modules that may be installed together in your system.

Wiring

To wire the 1203 base used by this module, connect a SCANport cable from the SCANport device to the desired channel. SCANport cables are available in either Male–to–Male or Male–to–Female configurations. You can connect cables of up to 10 meters (33 feet) between a SCANport device and any SCANport peripheral.

If you use a port expander, you must subtract the cable length between any device

and the expander from the maximum cable length used to connect a peripheral.
