Chapter 2. Quick start
M-2004/M-7004 is a digital temperature sensor module that
supports the DCON and Modbus RTU protocols. The host needs
to use some DCON or Modbus RTU commands to configure and
communicate with the M-2004/M-7004. ICP DAS provides the
DCON Utility Pro program that can configure and test
M-2004/M-7004 without understanding any DCON and Modbus
RTU command. Users can follow below steps to configure
M-2004/M-7004 and read temperature readings from
M-2004/M-7004.
Step 1: Install DCON Utility Pro on the host.
Note: DCON Utility pro supports M-2004/M-7004 for version 2.0.0.7
and later.
ICP DAS provides different versions of DCON Utility Pro for
different platforms that can be used to configure and test I/O
modules. The installation file locations for different platforms are as
follows:
