This manual describes the basic information of OMC-183-ML signal conditioning unit, as well as how to connect, install and debug.
This manual provides installation instructions and technical details for the OMC-183-ML signal conditioning unit, designed for meteorological applications. It covers sensor connections including wind, temperature, humidity, and barometric pressure sensors. The unit converts multiple sensor inputs into a serial signal and includes configuration options via RS-232 for user settings like QNH/QFE pressure and baud rates. It is intended for qualified engineers with basic electronics knowledge.
| Inputs | 4 x 0-5Vdc, 3 x 0-24mA, 2 x NMEA |
|---|---|
| Outputs | NMEA OUT (RS422), NMEA Return (RS422), RS232 TX/RX |
| Maximum Simultaneous Inputs | 4 analogue inputs |
It can connect to wind sensors (OMC-160, OMC-116, OMC-118, OMC-150/158), temperature & humidity sensors (OMC-406, OMC-443, OIC-406), and barometric pressure sensors (OMC-506, OMC-9501).
Yes, use command 8 to change baud rates for NMEA inputs and RS-232 output. Changes require saving with the 'Q' command and rebooting the device.
