ZKTeco Customer Pole Display ZK-VFD02

The ZKTeco ZK-VFD02 is a vacuum fluorescent customer pole display with a documented RS232 interface. It presents text from a compatible POS application on two rows of twenty characters. Its pole format provides a separate customer-facing text position while the host application remains responsible for the message or transaction detail.

The shared manufacturer profile specifies a blue-green display, a five-by-seven dot-matrix character font and a 200 cd/m² brightness rating. Each character is listed at 9 by 5.25 millimetres. These details describe the intended text format and physical legibility; the application determines the actual message and its formatting. The source does not establish how every POS application handles text longer than the display’s available rows.

The exact two-model datasheet distinguishes ZK-VFD02 from ZK-VFD01 by interface, so the correct connection is part of selecting the display rather than an interchangeable label. Its panel measures 224 by 85 by 40 millimetres, with a shared listed weight of 1.05 kilograms and a 5 V, 1 A supply requirement. The pole format places the text above the counter while the installation still needs an appropriate viewing position and cable route. Manufacturer-listed frame colours do not establish the colour currently supplied or its availability. Select the physical unit, supported command mode and receiving application together.
