Revision C
System Interconnects
All I/O connections are made through the back of the VersaMux-4000. Pin-outs
and connector identifications are provided in
.
NOTE:
Copper communications cables that attach to DNE products should be shielded
and the drain wire tied to the metal shell of the connector body (if applicable). If
required, place a split-core Fair-Rite, part number 0444167281 or equivalent, on
the NRZ cable, close to the EUT to be compliant with FCC Part 15, Subpart B, Class
A, 2004.
NRZ
The NRZ interface of the VersaMux-4000 accepts and generates RS-422 (Balanced)
signals using an EIA-530 DB-25 connector (the pin numbers are EIA-530, DCE).
provides a pin diagrams for the DCE NRZ connector with EIA-530
signal nomenclature.
provides a pin diagrams for the DTE NRZ
connector with EIA-530 signal nomenclature.
