Cable Management 
 
The following provisions are made for communication and power lines: 
 

• 

Polarization and locking of cable connectors 

• 

Strain relief of cables 

• 

Wire routing functionality 

• 

RJ series connectors for main and auxiliary RS-232 interfaces.   

• 

Power is brought to the unit through the main RS-232 cable 

• 

Power-pack is away from the unit and will attach to the main RS-232 cable 

 
Jam Clearance – Ejector Rod 
 
For easy removal of a jammed card, an ejector rod is accessible at the rear of the unit.  To clear a 
jam, the ejector rod is removed from the rear of the unit and inserted into an access hole on the 
back panel of the reader to push a card out of the front slot of the unit. 
 
Access to Optional SAMs 
 
The unit provides quick and easy access to the optional SAM ranch (a PCB with 6 optional SAM 
modules) through an access hatch at the base of the unit.  Contact MagTek for further 
information regarding optional SAM module.   
 
Tamper Resistant Security Module (TRSM), Optional 
 
The unit provides mechanical and electromechanical features that allow the enclosure to be used 
within a TRSM environment per ISO 9564.  Mechanical features visually indicate intrusion into 
the enclosure, and electromechanical switches on the Main PCB signal that the mechanical 
enclosure had been opened.  This allows the electronics to erase the keys in its memory area 
whether the unit is powered or not.  Contact MagTek for further information regarding optional 
TRSM.  
 
Electronics and PCBs 
 
The core electronic functions of the unit reside on a single PCB referred to as the Main PCB.  As 
an option, a second PCB referred to as the SAM Ranch may be plugged into the Main PCB. 
 
Main PCB Components 
 
The Main PCB Components are the microcontroller, RAM space, and ROM space.   
 

Microcontroller:  The main PCB is based upon a Philips XAS3 microcontroller.  This 
controller was used on previous MagTek products with previously developed firmware.
