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.
