RS-485 connections of COM2 for LP-8x2x/9x2x
This port provides
RS-485
serial communication functionality (DATA+ and DATA-) and is located on
the bottom-right corner on the LP-22xx, LP-52xx, LP-8x2x and LP-9x2x. This port allows a
connection to be made to modules that contain an RS-485 interface such as the I-7000 serial
modules (DCON Module), meaning that ICP DAS I/O series modules can be directly controlled via
this port with any converter. ICP DAS provides a very easy to use library of functions (libi8k.a) that
can use to easily communicate with I-7000, I-8000, I-9000, I-87k and I-97k series modules. Below
is an application example of the program code demo.
