•90‐264 VAC, 50‐60 Hz via a Universal Input power supply

VFD DC Power Requirements

•10 VDC to 14VDC (0.8 A max. at 12VDC)

LCD AC Power Requirements

Operational Environment

System Configuration

The VFD communicates with the host via the parallel port or EIA‐232 serial port of the host. Both interfaces are active at the same time. The display does not need to know which cable it is connected to.

However, both interface cables cannot be connected to the unit at the same time.

The LCD communicates with the host via the serial port only.
