Introduction

1.1 What is CYMOD?

CYMOD is a series of data acquisition modules. It provides a total solution of

the data acquisition network and control system. You can remotely control up to

256 CYMOD modules on RS-485 netowrk. All you need is to use a host

computer, like a liPC (Personal Computer), with one RS-232 serial port for

controlling the whole system. The maximum communication distance is 4000

feet from the host computer.

CYMOD is based on the RS-485 multi -drop network system, each module has

an unique address ID. Using simple ASCII command & response protocol

through standard RS-485 interface can control all the CYMOD modules in the

RS-485 network.

The CYMOD modules provide direct linkage to a wide variety of sensors and

perform all signal conditioning, scaling, linearization and conversion. The

modules can be used to measure temperature, pressure, flow, voltage, current

and numerous types of digital signals.
