Control Board
1
The control board is located on the presenter. It controls the main
functions of the dispenser and provides an interface to the PC core
of the terminal. The board controls the various sensors, solenoids
and motors for the sensing and presenting of bills. This includes
control for the divert mechanism and the transport drive. At power
up the board executes level 0 (firmware) diagnostics which report
using LEDs.
The control board is based around the Philips 80C562
microcontroller. There is addressing available for up to 64K of code
memory (EPROM) and 64K of Data memory (SRAM). This design
uses 64K EPROM and 32K of SRAM residing in the lower half of the
data area. The board will also accept 32K EPROMs requiring a
resistor jumper to be moved. The EPROM contains Level 0
diagnostics and executable code. The SRAM contains variables,
buffers and other data. SRAM is battery backed.
