Data Acquisition and Signal Conditioning Network
QTM-8000 Series
Figure 5.2 above depicts QTM-8000 Series data acquisition and signal con-
ditioning modules integrated into a wireless network. The upstream QTM-
8524 connected to the PC should be set for RS-232 communication, the down-
stream QTM-8524 connected to the module network should be set for RS-
485. Both QTM-8524 modules must be configured for the same frequency,
channel and baud rate. The attached QTM-8000 Series I/O modules must
also be configured at that same baud rate. (Note that because of the speed
limitation imposed by the QTM-8524, communication over this network can
not exceed 19.2 kbps, even though QTM-8000 Series I/O Modules are them-
selves capable of speeds up to 115.2 kbps.) Up to 256 QTM-8000 I/O mod-
ules can be configured in a network using one pair of QTM-8524 modules.
