C.3 RS-485 Communications using an MD485 RS-485

Interface

The HC2S3 can be interfaced to a CSI datalogger through an MD485 RS-485
Interface using the Rotronic E2-05XX-MOD RS485 cable as described below.
Settings for the RS485 port on the MD485 must be configured to match the
configuration of the HC2S3, which are 19200 baud, No Parity, 8 Data Bits, 1
Stop bit, and No Flow Control.

Device Configuration Utility (CSI software available as a free download) is
used to configure the MD485. Configuration settings for the MD485 are
shown below:

MD485 Tab: CS I/O AND RS-485

CS I/O Tab: SDC Address 7
