  • Page 8: Unpacking

    MA1048 MAQ20-FREQ Hardware User Manual 3.0 Unpacking Each MAQ20 Data Acquisition System component is shipped in electro-static discharge (ESD) protective packaging. Use appropriate ESD protection measures while unpacking. Check visually for physical damage. If physical damage is noted, file a claim with the shipping carrier.
  • Page 9 MA1048 MAQ20-FREQ Hardware User Manual The rugged inputs of the MAQ20-FREQ module have a high-level protection against overload and transient events and are also configured for a high level of sensitivity. A 50mV hysteresis band allows measurement of signals as low as 75mVp-p. While this is beneficial when interfacing to low level signals, the high sensitivity can cause false triggering if there is a large amount of noise riding on input signals.

The following diagram shows connection to a relay or dry contact sensor using the module excitation. A pullup resistor or direction connection between EXC and +IN can be used.

    MA1048 MAQ20-FREQ Hardware User Manual Figure 3: Possible System Configurations 6.0 Building a System An automated I/O module registration process reduces system setup to three basic steps: STANDARD SETUP PROCESS 1.) Install a MAQ20-BKPLx backbone in a DIN rail then insert a MAQ20-COMx module in the left- most position and apply power.

  • Page 13: Maintaining A System

    The system does not identify I/O modules by physical position on a backbone, only by registration sequence. MAQ20-940 - ReDAQ Shape Software for MAQ20 provided by Dataforth shows a graphical representation of a system based on registration sequence and not by physical position. Tools within this software package allow the user to reassign Registration Numbers thereby making graphical representations match physical location for a single, local backbone.

    Module identification including model number, serial number, date code and firmware revision are stored in registers at addresses 0 – 41. I/O modules in a system are identified in general by their model number (MAQ20-FREQ, MAQ20- VDN, etc.) and uniquely by their Serial Number printed on the side label (1234567-89). When I/O modules are installed in the system, only a general identifier is visible on the front of the module (FREQ, V, etc.).
