1. Introduction
The QTM-8000 Series of modules is comprised of analog and
digital I/O modules designed for a wide variety of data ac-
quisition and signal conditioning functions. These modules
are designed for an RS-485 communication network, and re-
quire an RS-485 to RS-232 converter in order to be accessed
through a standard PC serial port. The QTM-8520/8520R
module performs this function. Unlike many other convert-
ers, the versatile QTM-8520 contains a unique self-tuner ASIC
that allows it to process signals from multiple serial devices
operating at different baud rates and using different data for-
mats. This flexibility makes a QTM-8000 Series network an
extremely cost effective solution for remote signal monitoring
and control.
The QTM-8524 is a radio modem module that can implement
QTM-8000 Series modules as a wireless data acquisition and
signal conditioning network. The wireless communication
modules form RF communication between peer-to-peer or
multi-point structures, which eliminates the use of long cables.
Like the QTM-8520, the QTM-8524 functions as a RS-485 to
RS-232 converter. However, it does not contain the self-tuner
ASIC which means that all modules operating in a QTM-8524
wireless network must be functioning at the same baud rate
and using the same data format. To implement a wireless net-
work functioning at several different baud rates, a QTM-8520
module must be used in conjunction with multiple pairs of
QTM-8524 modules.
