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.
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.
RAM Space: 40 K bytes
ROM Space: ROM Flash:
Main Program Memory: 512 K Bytes
Boot Loader Memory: 24 K Bytes
Configuration Memory: 8 K Bytes
Host Serial Port
The RS-232 Host Serial Port provides serial communications between the Reader/Encoder and
the Host Computer. In addition, the Host Serial Port carries DC power from the remote power
pack to the Reader/Encoder. The Host Serial Port is capable of communication speeds of up to
115 K bits/sec.
USB Port
The Host USB 1.1 Port provides communications between the Reader/Encoder and the Host
Computer. The USB Cable, 5-pin mini B Plug, connects to host 4-pin USB Type A Plug, with
10-pin RJ45 and 12V/Ground connector for Power Supply.
Auxiliary Serial Port
The Auxiliary Serial Port provides serial communications and power between the
Reader/Encoder and an external device. The Auxiliary Serial Port is capable of communication
speeds of up to 19.2 Kbits/sec. The port is also capable of carrying +12 VDC at up to 1 A for a
device connected to this port.
