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.
