The AUX tab is used to specify communication settings for your auxilliary serial port. Serial devices, such as bar code readers and APRS radios, can interface with ArcPad through this port via applets and extensions. The settings should match the output settings of your serial device.
Choose the COM port that your serial device is connected to on your PC or mobile device. The drop-down list only displays the active serial ports on your PC or mobile device.
The default is COM1.
Choose the baud rate of your serial device’s output.
The default is 4800.
Tap Advanced to specify additional communication settings for your auxiliary serial port. For most serial devices, it is not necessary to specify these additional serial communication settings.
The advanced serial port parameters are described under topic Advanced Serial Port Parameters in section GPS and Rangefinder Preferences.
