Communication Interface T8151B
Issue 21 Apr 10 PD-T8151B 13
2. Installation
The Communication Interface can be installed in any I/O slot of a controller or expander chassis,
however, peer to peer communications is only supported from the processor chassis.
When installed in the chassis, the communication Interface connects to external systems via either a
Communication Interface Adaptor T8153 or a TC-305-01 Communications Cable with flying leads.
2.1. Module Insertion/Removal
CAUTION:
The module contains static sensitive parts. Static handling precautions must be observed. Specifically
ensure that exposed connector pins ARE NOT TOUCHED. Under no circumstances should the
module housing BE REMOVED.
Before installation, visually inspect the module for damage. Ensure that the module housing appears
undamaged and inspect the I/O connector at the back of the module for bent pins. If the module
appears damaged or any pins are bent, do not install the module. Do not try to straighten bent pins.
Return the module for replacement.
Ensure that the module is of the correct type.
Record the module type, revision and serial number of the module before installation.
To install the module:
1. Ensure that the field cable assembly is installed and correctly located.
2. Release the ejector tabs on the module using the release key. Ensure that the ejector tabs
are fully open.
3. Holding the ejectors, carefully insert the module into the intended slot.
4. Push the module fully home by pressing on the top and bottom of the module fascia.
5. Close the module ejectors, ensuring that they click into their locked position.
The module should mount into the chassis with a minimum of resistance. If the module does not
mount easily, do not force it. Remove the module and check it for bent or damaged pins. If the pins
have not been damaged, try reinstalling the module.
2.2. PCBs and Connectors
2.2.1. External I/O Connector
This connector provides a number of discrete input and outputs. These provide the Communication
Interface with the serial and Ethernet connections. The connector is a 78+2-way DIN 41612 M-type
connector. See Table 3 for connector pin-out details.
