Appendix F: RS-485/422 Options
You may order the DFlex-4/104 adapter with RS-485/422 Serial
Line Interfaces Modules. The RS-485/422 electrical interface is a
reliable high-speed serial link that offers superior noise immunity
and multi-drop network connectivity. The RS-485/422 electrical
interface is also a superset of the RS-422 electrical interface.
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.
Installation
The DFlex-4/104 adapter has two SLIM sockets that accept Serial
Line Interface Modules. SLIM 1 socket interfaces ports 1 and 2.
SLIM 2 socket interfaces ports 3 and 4. Please refer to
Chapter
2: Hardware Installation for the location of the SLIM sockets
and to Appendix D: SLIM Insertion/Removal for the proper
procedures to installing and removing SLIMs.
Your DFlex-4/104 adapter and Serial Line Interface Module
(SLIM) are very sensitive to static electricity. Make sure that
before you remove them from the anti-static shipping bag, you
wear an anti-static wristband. When you remove them from the
anti-static bag, handle them only by the edges and place them on
the anti-static bag or an anti-static mat.
