About the Fiber Module

Use this module when a medium-distance (distances of 3000m/ 9843ft) fiber link is

required between two ControlNet products. This fiber link provides ground

isolation between nodes and is less susceptible to noisy environments than

traditional copper media.

The module provides:

•two fiber channels

•activity LED indicators for each fiber channel

Figure 1 Components of the Module

IMPORTANT The distance that can be supported is dependent on the quality

of the fiber, number of splices, and connectors. The total loss of

the fiber link must be less than 13.3 dB.

Publication 1786-IN011B-EN-P - October 2000

Mount the Fiber Module

To mount the module on the DIN rail:

1. Position the module on a 35 x 7.5mm DIN rail (Allen- Bradley part number

199- DR1; 46277- 3; EN 50022) at a 30oangle.

2. Hook the lip on the rear of the module onto the top of the DIN rail, and

rotate the module onto the rail.

Publication 1786-IN011B-EN-P - October 2000

3. Press the module down onto the DIN rail until flush.

The locking tab should snap into position and lock

the module to the DIN rail.

4. If the module does not snap into position, use a screwdriver or similar

device to move the locking tab down while pressing the module flush onto

the DIN rail. Release the locking tab to lock the module in place. If

necessary, push up on the locking tab to lock.

ControlNet Modular Repeater Medium Distance Fiber Module 9

Publication 1786-IN011B-EN-P - October 2000

5. Remove the protective backplane cap as shown in “Remove the Protective

Caps” on page 10.

6. Once attached to the DIN rail, slide modules to the left to mate with the

repeater adapter or another repeater module.

7. Connect the fiber cable as shown in “Connect the Fiber Cable” on page 13.

ATTENTION

Be certain that the adapter and repeater modules are secured

together with DIN rail anchors. Failure to do so may result in

the loss of communications and/ or cause damage to the

modules. The total number of modules that can be attached to

the repeater adapter can not exceed four or the total power

consumption of the modules can not exceed 1.6A @ 5VDC,

whichever comes first.

IMPORTANT

If you exceed the module or power limit, you may cause

damage to the repeater adapter and modules.

IMPORTANT

If this is the right–most module, a DIN rail latch must be used

on the right side of the fiber module.

Remove the Protective Caps

1. Remove the protective caps from the fiber ports that you are going to use.

2. Save the caps for future use.

Figure 2 Protective Caps

If you plan: Then:

not to use channel(s) keep the protective caps on the channels to protect

the unit from dust.

to place the module in storage keep the protective caps on the channels to protect

the unit from dust.

to connect another module to the right

backplane connector

remove the protective backplane cap and save cap

or future use.

not to connect to the right backplane connector leave the backplane cap on.
