Installation Instructions

10 ControlNet Daughtercards

Publication 1788-IN005B-EN-P - October 2005

To wire the module:

1. Hold down the latch and insert the Channel A zipcord connector into the duplex

socket until the pins and latch lock into place.

2. Make sure you insert the blue pin (receive) of the zipcord connector into the left Rx

and the black pin (transmit) into the right Tx socket.

ControlNet Network Topology Example

If Your Network Supports Connect the Fiber Cable

nonredundant media

(1788-CNF or -CNFR)

to the channel A connector on the module

(channel B on the 1788-CNFR is not used.)

Recommended when using channel A for non-redundant media.

redundant media

(1788-CNFR)

from trunk-cable A to channel A on the 1788-CNFR and from trunk-cable B

to channel B on the 1788-CNFR.

IMPORTANT

It is not necessary to install nodes on coax segments. If you are only

using the repeaters to extend, then install a 75-ohm terminator

(1786-XT) on the BNC coax connector on the fiber repeater adapter

(1786-RPA). Do this to all repeaters that are not connected to coax

segments.
