MIR 6000
Series User’s Manual
1.1 Overview
The MIR Series is a set of intelligent sensor-to-computer
interface modules containing built-in microprocessor. They are
remotely controlled through a simple set of commands format and
transmitted in RS-485 protocol. They provide signal conditioning,
isolation, ranging, A/D and D/A conversion, data comparison,
and digital communication functions. Some modules provide digital
I/O lines for controlling relays .
Software Configuration and Calibration
By merely issuing a command from the host computer, you can
change an analog input module to accept several ranges of voltage input,
or RTD input. All of the module’s configuration parameters including
I/O address, HI and LO alarm,calibration parameters settings may be
set remotely.Remote configuration can be done by using the provided
menu-based software and calibration commands.
By storing configuration and calibration parameters in a nonvolatile
EEPROM, modules are able to retain these parameters in case of power
failure.
Watchdog Timer
A watchdog timer supervisory function will automatically reset the
MIR modules in the event of system failure. Maintenance is thus
simplified.
Power Requirements
The modules are designed for supplies power within the range
of +15 to +2
5
V
DC
. The power supply
ripple must be limited to 5 V peak-to-peak, and the immediate ripple
voltage should be maintained b15 and +
25
V
DC
.
