INSTRUMENT DESCRIPTION
2.1
DESCRIPTION
The OMD 202RS model series are 4/6 digit large panel programmable displays for the projection of data from data lines RS 232,
RS 485 in protocoles ASCII/MESSBUS/MODBUS/PROFIBUS. The instrument can be supplied with either a 3-colour LED display
(red/green/orange) or with hight intensity SMD LEDs (red or green with brightness of 1 300 mcd).
The instrument is based on an 8-bit microcontroller, which secures high accuracy, stability and easy operation of the
instrument.
