Slide-in-Module Media
Converter
RS485/422 Copper to Fiber
Transition Networks CRS4Fxxxx-
10x series media converters are
designed to be installed in the
PointSystem™
chassis and connect
RS485/422 copper cable to fiber-
optic cable at asynchronous data
rates up to 1.25 Mb/s.
The CRS4F31xx-10x media converters use a male DB-9 port for the copper link:
The CRS4F32xx-10x media converters use a 6-position terminal block for the copper
link:

Maximum cable distance is 1200m
(4000 ft)
@ <90 kb/s decreasing logarithmically to
92m
(300 ft)
@ 500 kb/s.
**Typical maximum cable distance. Actual
distance is dependent upon the physical
characteristics of the network installation.
