Many of the
models within the Integra product portfolio feature an
integral RS485 communication port, allowing direct
connection to SCADA systems via Modbus RTU or Johnson
Controls Metasys NII protocols. However, the SCADA systems
or PC based equipment used for remote monitoring of
electrical and power parameters often incorporate RS232
communication ports, therefore conversion to RS485 is
necessary. The 9D-485 module is a simple non-isolated two
wire half duplex RS485 converter which fits into any PC
based system.
This port powered two-channel module converts the TD and RD
RS232 lines to balanced half-duplex RS485 signals via a 9
way female D type connector on the RS232 side, and a screw
clamp terminal block connector on the RS-485 side. The
module has an internal connection to prevent data
transmitted from the RS232 port from being echoed back to
the RS232 port.
