Compact 83-Key Layout for Space-Constrained

This Cherry G84-4420LPBEU-2 is a 14.5-inch UltraSlim PS/2 keyboard with an integrated optical trackball and two mouse buttons. Mechanical keyswitches with gold crosspoint contacts are rated for 20 million actuations. The unit weighs 1.24 lbs and measures 0.77 inches in height.

Suited for Rack, Kiosk and POS Installations

The 83-key layout omits Windows keys and a numeric keypad, fitting 15-inch wide mounting spaces in retail, medical, banking and industrial environments. Buyers who need a full numeric keypad or dedicated function key row should look at larger form factors.

PS/2 Dual-Port Interface

Connection requires two PS/2 ports on the host system for keyboard and trackball signals. USB-only or single-port PS/2 hosts cannot support both functions without an active adapter not supplied with this unit.

Questions about this item

Does the 83-key layout still provide all standard keyboard functions without dedicated Windows keys?

Yes, the 83-key layout includes all standard keyboard functions while omitting Windows keys, making it suitable for POS and embedded systems where those keys are not required.

Will the PS/2 connectors work with a legacy motherboard that only has a single PS/2 port?

The keyboard has two PS/2 connectors — one for the keyboard and one for the integrated trackball — so a system with only one PS/2 port cannot support both functions simultaneously.

How can I verify the optical trackball is functioning correctly after connecting the keyboard?

Move the trackball and observe cursor movement on screen; press the two adjacent mouse buttons to confirm left- and right-click actions register in the operating system.
