RS-449
C–21
RS-449
The RS-449 cable connects an HSD module to an
RS-449-compatible network or network device.
You can configure an HSD module through the software
as DCE or DTE. Use either the DCE or DTE version of an
RS-449 cable, depending on the configuration. Refer to
the Administration Guide to learn how to configure
modules.
The cables provide
❐
A 26-pin D-shell male that connects to the HSD
module
❐
A 37-pin D-shell male or female that connects to the
network or device
When building an RS-449 cable, use no more than
200 feet (61 meters) of Belden 9812/9813 computer cable,
or equivalent.
These tables list the pin assignments:
