Serial Line Interface Modules (SLIM)

The DFlex-4/104 adapter accepts interchangeable electrical line

interfaces. These Serial Line Interface Modules (SLIM) provide

the electrical interface for two asynchronous communication

ports. If you order RS-232 or RS-232/Fast modules please refer

to Appendix E: RS-232 Option for more technical information.

If you order RS-485/422 modules please refer to Appendix F:

RS-485/422 Option for more technical information. If you order

RS-423 modules please refer to Appendix G: RS-423 Option for

more technical information. If you order 20mA current loop

modules please refer to Appendix H: 20mA Current Loop

Option for more technical information.

SLIM Installation

The DFlex-4/104 adapter has two sockets that accept Serial Line

Interface Modules (SLIM). Each SLIM provides the RS-232 or

RS-485/422 or RS-423 or 20mA current loop receivers and

transmitters to condition two serial ports. SLIM socket 1

interfaces ports 1 and 2. SLIM socket 2 interfaces ports 3 and 4.

Please refer to Figure 7 for the SLIM socket to serial port

relationship.

WARNING

You must insert Serial Line Interface Modules into all of the SLIM

sockets to attain the communications functionality of your

DFlex-4/104 adapter.
