RS-232/485 CONVERTER
4. Installation
Once the Converter is properly configured, it is
ready to connect to your system. This section tells
you how to properly connect the Converter to the
twisted-pair and EIA/TIA-574 interfaces, and how
to operate the Converter.
4.1 Twisted-Pair Connection
The Converter supports 2-wire or 4-wire communi-
cation between two or more EIA/TIA-574 devices at
data rates up to 115.2 Kbps. There is one essential
requirement for installing the Converter:
To function properly, the Converter needs
one or two twisted pairs of metallic wire. These
pairs must be unconditioned dry metallic wire,
between 19 and 26 AWG solid copper core,
unshielded (the higher-number gauges may
limit distance). Standard dialup telephone
circuits that run through signal-equalization
equipment are not acceptable.
