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.
