Robust DataComm rdc485ic-sp Converter 仕様ガイド
Model: Rdc485ic-sp
Self-Powered RS-232 to 2-wire RS-485 Converter
The rdc485ic-sp provides excellent
versatility in a compact package.
Requiring no AC power or batteries
for operation, the converter supports
asynchronous RS-232 data rate to
115200 bps over one unconditioned
twisted pair in half duplex mode.

The RS-232 interface is factory
configured as DCE. It connects directly
to DTE such as a terminal or PC. If you
must use a cable to connect the DCE to
your DTE device, use a straight through
cable no longer than 50 feet (15.2m)

To function properly, the converter
must have one twisted pair of metallic
wire. This pair must be unconditioned
metallic wire, solid conductor, unshielded
twisted pair, between 19 and 26 AWG
(the higher numbered gauges may limit
distance somewhat). We recommend
using CAT 5 solid 24AWG cable.
