Optional Modules & Accessories
Select optional data capture modules, expansion features, and compatible accessories to match your deployment needs.
Brightness, M12 I/O, Battery and Mounting Configuration
The compact K181J build can vary by screen brightness, M12 data branch, CAN, video, NFC, battery, regulator and mounting kit. Assign one configuration identifier to the Android image, harness, antenna set and mechanical package.
Optional
Wi-Fi/GPS/4G antennas
The ordered K181J build names Wi-Fi/GPS/4G antennas, its connector and its mounting position rather than assuming a universal antenna.
