Hooking-Up the TMZ (TPRG)
Configuring the TMZ
One of the benefits of the TMZ is that there are no
internal or external controls to adjust or settings to
change. All operating parameters are set using a
PC and Moore Industries’ Intelligent PC Configuration
Software.
The software settings are downloaded to the
transmitter in the form of a Configuration File and
stored in the instrument’s memory. You can save a
backup copy of the file on your PC hard drive or disk.
The transmitter communicates with the PC through an
RS-232 connection to the PC’s serial port or through
the MODBUS output with a fixed baud rate at 19.2k.
