869 RFID Reader Service Instruction Manual

Reader Module

The 869 reader module is comprised of the DSP engine, RF circuitry,

power regulation circuitry and other necessary components. The reader

module is constructed from a printed circuit board assembly, suitable RF

shielding, and incidental hardware. The 869 reader module is a sub-asĆ

sembly of the 869 Reader.

869 Serial Reader Module

An electrical block diagram of the reader module is shown in Figures 1 and

2. External connections may connect directly to the circuit card's connecĆ

tor, for items such as DC power, or RF signals, and the circuit board genĆ

erated/processes these signals. Additionally, it has external connectors for

data communications and GPIO signals.
