The DCP-485 is a compact RS-232-
to-RS-485 converter which features
a complete electrical isolation
barrier and heavy duty electrical
surge protectors. These devices
feature a DIN rail mountable
enclosure, for application to a
junction box, a panel, a relay rack,
the side of your computer, or
anywhere a DIN rail can be
mounted. Isolation is provided by
optical couplers and a transformer-isolated
dc-to-dc converter. The
RS-232 connection is made through
male or female EIA 9-pin D sub
connectors, or a 3-wire RS-232
connection can be made through
convenient pluggable screw
terminals. The RS-485 connections
are made through convenient
pluggable solderless screw terminals.
The DCP-485 series is designed for
full duplex operation over two-wire
pairs. Outputs are tri-state, allowing
multidropping of up to 32 units. Data
rates are up to 115.2 K bits per
second (baud). Four diagnostic LED indicators are provided
for installation guidance
and system troubleshooting. The
RS-232 interface includes Request
To Send (RTS) and Data Terminal
Ready (DTR), either of which can be
used via a DIP switch to enable the
RS-485 transmitter. Alternately, the
DCP-485 offers automatic line
switching: the RS-485 transmitter is
enabled automatically by each
character sent on the RS-232
Transmit Data (TD) line.
Additionally, the RS-485 transmitter
and receiver can be independently
enabled continuously or under
RS-232 control. A convenient null
modem switch is provided for the
data lines. Also, line termination
switches independently connect line
termination and line bias resistors to
the RS-485 lines. The units are
powered from wide-range voltages
of +10 to +30 Vdc through pluggable
solderless screw terminals.
