System Technical Specifications

This appendix describes the engineering specifications for the IT2200 Reader System 
components.

The reader logic card requires +5 VDC and +12 VDC power, which is supplied by the 
host computer or lane controller power supply.

Circuit breakers and disconnects are unnecessary with the reader logic card. Because 
all input and output signals have limited short circuit current drive, there is no need to 
include a circuit breaker. Lightning protection is achieved through the use of optically 
coupled signals between the reader logic card and the RF module. These two units are 
connected via copper wire with optical isolation on the reader logic card. The card 
provides all of the following interfaces: card edge, ISA, RS-232, optically isolated 
input/output interface, optional external power, background debugger mode (BDM), 
TDM, diagnostics, and IP daughterboard.

Table C-1 shows the electrical requirements for the IT2020 Reader Logic Card. 
Table C-2 shows the power consumption estimates for the card’s individual assem-
blies.
