AUX Port Connection
The AUX port provides ignition sense connection to the MW810 Mobile Workstation.
The AUX port can also used as power supply of 5 to 27 VDC (pr-programmed Voltage) at
The AUX port can also used as power supply of 5 to 27 VDC (pr-programmed Voltage) at
maximum current of 1.5A to any auxiliary equipment inside the vehicle.
The AUX port provides four predefined GPIO (the port can be set as input or output) and two
The AUX port provides four predefined GPIO (the port can be set as input or output) and two
GPO (output only) ports. The output Voltage can be pr-programmed to 5 to 27 VDC at
maximum current of 150mA.
To set the GPIO ports and power supply output in the CPU Codeplug, refer to Motorola
To set the GPIO ports and power supply output in the CPU Codeplug, refer to Motorola
Solutions MW810 Mobile Workstation, R2.0, Administrator Guide (P.N: 6802988C42).
The Low “0” input signal range is 0 to 0.2V and the High “1” input signal range is 3.3 to 33V.
The Low “0” input signal range is 0 to 0.2V and the High “1” input signal range is 3.3 to 33V.
For complete pin assignment of the AUX port, refer to Table 4.
Ignition Sense Connection
To install the ignition-sense cable between the AUX connector and the vehicle ignition line,
carry out the following steps:
Step 1. Connect one end of the ignition-sense wire to pin 8 of the AUX connector, and the
Step 1. Connect one end of the ignition-sense wire to pin 8 of the AUX connector, and the
other end to the vehicle ignition switch.
Step 2. Connect pin 7 to the vehicle Ground.
