NOTE WHEN USING USB COMMUNICATION TO MULTIPLE SYSTEMS:
If multiple systems are connected using USB communications, the systems will be populated in the
software in the order that they are powered up. For example, the first system powered up would be
assigned as System 1 and the second as System 2. Thereafter, if the host computer power is cycled or
the MAQ
®
20 data acquisition system power is cycled, the software will re-discover the systems and again
generate the system images in the software. System number assignments may remain System 1 and
System 2 as previously assigned, or they may swap and become System 2 and System 1.
3.2 COM Module
To setup and configure the communications (COM) module, click on the COMx module graphic. The
COM module setting panel has three tabs [Setup Modules Slot, Set COM and SD Memory Card].
Setup Modules Slot Tab:
Basic information for all modules in the system is displayed at the top of the panel including
model number, serial number, date code, firmware revision, and Modbus start address in the
system map.
When power is applied for the first time to a system, the COM module automatically registers all
I/O modules in the system. The registration sequence by slot number is displayed in the COM
module configuration panel. This sequence may not match the actual physical sequence of the
I/O modules in the system. To change the slot number in the software which a module is
installed in, click on the row to select the module then use the [Up] and [Down] buttons to move
the module to the slot number which matches the actual physical location.
