ElitePad Dock Purpose

This expansion dock connects the ElitePad tablet to stationary retail peripherals through multiple legacy and USB interfaces. It is designed for point-of-sale environments that require serial and powered USB connections from a single mobile device.

Sustained Operation Behaviour

The dock provides dedicated power rails for continuous peripheral use: one 24 V port for a printer, two 12 V ports for complex character VFD and optional PIN pad, and four 5 V ports for scanners. Four DB9 serial ports are jumper selectable between 5 V and 12 V to match legacy equipment requirements.

Setup Verification Required

Confirm the tablet is an ElitePad model supported by this dock before ordering. Verify that each attached peripheral matches the voltage provided by its designated port and that serial devices are configured for the selected 5 V or 12 V jumper setting on the DB9 connectors.

Questions about this item

How much power does the dock draw when the ElitePad and all four serial peripherals are running continuously?

The dock supplies 5 V or 12 V to each of the four DB9 serial ports via jumper selection, so total draw depends on the connected legacy devices rather than a fixed dock figure.

Which cables or power adapters must I already have to connect the ElitePad to this dock?

The dock provides one 24 V USB port for a printer, two 12 V USB ports for a VFD or PIN pad, and four 5 V USB ports for scanners, so you need matching USB cables for each peripheral.

Will the four powered DB9 ports work with the 12 V serial barcode scanner I already use?

Yes, each DB9 port is jumper selectable for 5 V or 12 V, allowing you to set the correct voltage for your existing 12 V scanner.
