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.
