Compaq 380 manual External Auto-Ranging Power Pack, Firmware

Section 1. Features and Specifications

External Auto-Ranging Power Pack

The Reader/Encoder is powered from an external power-pack, which is located near the Host Computer System. Power is routed to the Reader/Encoder through the Host RS-232 cable.

Auto-Ranging Input

The external power pack features an Auto-ranging AC input that allows for direct connection to either a 100 VAC or 220 VAC, 50 to 60 Hz.

Output Rating

The power pack is rated at approximately +12 VDC @ 4 A ± 5%.

Firmware

The firmware for the Reader/Encoder is based upon existing MCP protocol and command set.

Memory Cards

The firmware supports smartcard interfaces to memory cards.

FLASH Download Protection

To prevent illegal applications from being downloaded into the Reader/Encoder, the firmware verifies that the downloaded FLASH program is provided (authorized) by MagTek. If the program cannot ID itself correctly, the boot loader program abandons the FLASH load sequence and returns a unique status code that identifies the situation to the Host.
