secondary node.

8032 Microcontroller Port ConfigurationThe port configuration of the 8032 microcontroller is detailed under thefollowing headings:

� Port 0 configuration� Port 1 configuration� Port 2 configuration� Port 3 configuration.

Port 0 ConfigurationPort 0 is configured as the multiplexed low-order address/data bus for accessto external program and data memory, and to access the memory mapped I/Othat exists on the module.

Port 1 ConfigurationPort 1 is configured to drive four status LEDs on bits 0 to 3 (level 0 LEDs),three general purpose outputs on bits 4 to 6 and the TX_EN line forcontrolling the SDC transceivers on bit 7. The general purpose outputs, whichare used to drive indicators, are passed through an inverting buffer to providebetter source/sink characteristics.

Port 1 assignments, and their active level at the 8032, are as follows:

Port 2 ConfigurationPort 2 is configured as the high order address byte during access to externaldata/program memory and memory mapped I/O devices.

Function

1.0 High LED_1 Switches the level 0 LED on.




1.4 High IN_SERVICE- Turns the IN_SERVICE LED on.

1.5 High SUPERVISOR- Turns the SUPERVISOR LED on.

1.6 High ERROR- Turns the ERROR LED on.

1.7 Low TX_EN Enables serial data transmission from the 8032 to the SDC link.




Port 3 ConfigurationPort 3 is configured as follows:

Communications Interface ControlThe communications interface employed on the SDC secondary nodes is aserial multidrop link which facilitates the exchange of commands and databetween a master node and a number of secondary nodes.

Control SignalsThe control signals for the communications interface are as follows:

Data SignalsThe serial data is passed over the SDC link using the following signals:

LIQUID CRYSTAL DISPLAY PANELThe LCD panel, mounted on spacers above and connected to the interfaceboard, is capable of displaying 240 x 128 pixels. The LCD displays 16 lines of32 characters (7 x 8 font) which allows emulation of the front screen, in textmode.

The use of the LCD panel is software defined and can echo input from theoperator keyboard and be utilized as an output device for error reporting, SOHreports and operator prompts.

LineNo.

Active Level

SignalName

Function

3.0 N/A RXD Configured as 8032 serial data input (from SDC link).

3.1 N/A TXD Configured as 8032 serial data output (to SDC link)

3.2 High to Low

INTO- Keyboard controller interrupt input pin. When the keyboard controller detects a key press, a high to low transition occurs on this pin.

3.3 High to Low

BUZZER- Causes the on-board buzzer to emit a 100ms beep.

3.4 N/A MODE_SEL This input shows the state of the MODE_SEL signal.

3.5 Low COMMS_LED 0 = COMMS LED on.1 = COMMS LED off.

3.6 Low WR- External memory and memory mapped I/O write strobe.

3.7 Low RD- External memory and memory mapped I/O read strobe.

Signal DescriptionTX_EN Enables serial data transmission from the 8032 across the SDC link.

SYSTEM_RESET This signal is generated on the EOP module through an on-module switch, and controls the SDC RESET transceiver direction control. When this signal is low, the transceiver is monitoring the SDC link for a RESET condition on the link.When this signal is high, the transceiver direction is switched, and the EOP module broadcasts a RESET over the SDC link.

Signal DescriptionTXD Serial data output from the 8032 to the SDC link data transceiver.

RXD Serial data input from the SDC link data transceiver to the 8032.




The contrast of the LCD can be altered by adjusting the contrast controllocated on the front of the EOP.

LCD InterfaceThe LCD interface on the EOP module consists of the following:

� LCD controller� Display memory - 8K of SRAM� External character generator - 64K EPROM� 8-bit configuration port� Two 8-bit diagnostic ports.

The LCD controller is a general purpose dot matrix liquid crystal graphicdisplay controller which can control up to 512K pixel display and supportsboth graphics and text modes.

In text mode, the LCD controller can display characters from either itsinternal character set or the external character EPROM.

A full screen of graphics contains 240 x 128 pixels of information.Therefore, the 8K SRAM used for display memory can hold two full graphicscreens.

As the LCD controller can only access 4K of display memory at one time,the display swapping function is external to the controller's normal function.

An external 64K EPROM of character memory is used to allow for 15character sets and EPROM identification.

KEYBOARDSThe EOP module has the following keyboards:

� A 16-key keyboard� Two 1 x 4-key FDK keyboards.

16-Key KeyboardThe 16-key keyboard is mounted on spacers above and connected to theinterface board and has a 4 x 4 grid.

The key legends are configured by use of an overlay.

FDK KeyboardsThe FDK keyboards are two 1 x 4 keypads which allow selection of controloptions from the displayed screens.

The key legends are black arrows on a white background.

INDICATORSThe five LEDs, provided on the EOP, are mounted on the interface board andhave the following functions:

� IN SERVICE (Green) - Illuminated to indicate the terminal/ATM is readyfor transactions

� SUPERVISOR (Green) - Illuminated to indicate the terminal/ATM is insupervisor mode

� POWER (Green) - Illuminated to indicate the module is receiving a +5V dcsupply from the terminal/ATM

� ERROR (Amber) - Illuminated to indicate a fault has occurred requiringoperator intervention




� COMM (Amber) - Flashes to indicate communications polling. Can bedriven by either of the following sources:� An external signal (LED_SIG-) which emanates from a

communications board in the terminal/ATM� Under software control (COMMS_LED-) which is controlled by the on-

module microcontroller.

NOTE: The IN SERVICE, SUPERVISOR and ERROR LEDs are softwarecontrolled.

SWITCHES

On-module SwitchesThe two switches, provided on the EOP, are mounted on the interface boardand have the following functions:

� RESET - A biased spring-loaded switch which provides, when activated, areset condition to the terminal/ATM through the SDC interface

� MODE - A toggle switch which allows the operator to signal to theterminal/ATM that a change of state in the operating mode is required.The legends on the switch are:� NORMAL� SUPERVISOR.

Off-module SwitchesThe operational mode of the terminal/ATM can be controlled by one or moresingle pole, double throw switches external to the EOP.

When the off-module switches are fitted, the on-module mode switch isinoperative.

The off-module switches are daisy-chained together and connected to theEOP through connector J5 as follows:

The switch positions show the terminal/ATM is in normal mode. Whenany switch is activated the terminal/ATM is automatically put in supervisormode.

AUDIBLE INDICATORThe EOP module contains an audible indicator that is used to verify that akey on one of the keypads has been activated.

The audible indicator is under software control and is activated by theBUZZER- signal.

When the audible indicator is activated, an audible response is triggeredthat lasts for approximately 100 milliseconds. The circuit can be re-activated




at any time re-starting the 100 millisecond count.

NOTE: If the circuit is re-activated before the 100 millisecond count hasfinished the next 100 millisecond pulse will follow on and a continual beepwill be heard.
