INTRODUCTION TO THE M SERIES DAC

The BayTech M Series Data Acquisition and Control (DAC) models are versatile

multifunction units used in data collection and process control. Typical applications

include security alarm monitoring, HVAC systems, medical data systems control,

manufacturing, and environmental data control. An M Series system consists of a

base unit, host communication module(s), and various I/O modules.

The base unit is comprised of 3, 4, 6, 9, or 16 card slots, activity LEDs, service port,

time-of-day clock (optional), power supply, and an internal high speed data bus. The

service port and optional service modem allow menu-driven configuration of the main

unit and installed modules from a local or remote terminal.

The host communication modules are the primary user interface to the M-Series DAC

system. These modules allow the user to connect to the main unit or I/O modules and

change configuration, send and receive data, and issue data commands. The host

modules include:

IMPORTANT: The first module slot of any unit equipped with LCD and

front panel controls must be occupied by a host module.

The I/O modules are used to interface directly to various peripheral devices such as

security/alarm systems, process control systems, medical data systems, and

environmental control systems. The I/O module types include:
