1 Contents Chapter 10.4 Basic SDC Operator Panel INTRODUCTION The Basic SDC Operator Panel module (operator panel) provides an interface to the 56XX range of terminals/atms to allow replenishment and diagnostic testing to be carried out. When mounted in the terminal/atm, the operator panel will be protected by a keylocked secure panel. The secure panel, part of the terminal/atm, will incorporate a transparent window to allow the operator panel to be viewed. The operator panel, a secondary node on the Serial Distributed Control (SDC) bus, supports State Of Health (SOH) reporting. There are two versions of the operator panel: Original - Part No Latest - Part No The basic difference between the two versions is the interface board. Throughout this chapter, the interface board Part No. (refer to General Description) will be used, where relevant, to distinguish between the two versions of operator panel

2 GENERAL DESCRIPTION The operator panel consists of the following: Interface board: (Original) (Latest) Liquid Crystal Display (LCD) panel Keyboard Indicators Switches Audible buer. INTERFACE BOARD The interface board is based on an 8032 microcontroller and carries the operator indicator LEDs and switches. The board is connected to the terminal/ ATM and operator panel components through seven connectors. LIQUID CRYSTAL DISPLAY PANEL The LCD panel, mounted on spacers above and connected to the interface board, is a 2 x 40 LCD display capable of displaying alphanumeric characters defined in a 5 x 7 matrix. The use of the LCD panel is software defined and can echo input from the operator keyboard and be utilied as an output device for error reporting, SOH reports and operator prompts. The contrast of the LCD can be altered by adjusting a variable resistor (VR1) which is located on the interface board. KEYBOARD The keyboard, mounted on spacers above and connected to the interface board, is a 5 x 4 keypad consisting of: All the hexadecimal characters (0 to 9 and A to F) AUX key - used to select diagnostic testing ENT key - used to action the function code keyed in CNL key - used to cancel the function code just keyed in CLR key - used to clear the buffer store in the keyboard controller and reenable it to accept new data. INDICATORS The five LEDs, provided on the operator panel, are mounted on the interface board and have the following functions: IN SERVICE (Green) - Illuminated to indicate the terminal/atm is ready for transactions SUPERVISOR (Green) - Illuminated to indicate the terminal/atm is in supervisor mode ERROR (Amber) - Illuminated to indicate a fault has occurred requiring operator intervention POWER (Green) - Illuminated to indicate the module is receiving a +5V dc supply from the terminal/atm

3 COMMS (Amber) - Flashes to indicate communications polling. Can be driven from either an external signal (LED_SIG-) or by the microprocessor on the interface board. SWITCHES NOTE: The IN SERVICE, SUPERVISOR and ERROR LEDs are software controlled. On-module Switches The two switches, provided on the operator panel, are mounted on the interface board and have the following functions: RESET - A biased spring-loaded switch which provides, when activated, a reset condition to the terminal/atm through the SDC interface MODE - A toggle switch which allows the operator to signal to the terminal/atm that a change of state in the operating mode is required. The legends on the switch are: NORMAL SUPERVISOR. Off-module Switches The operational mode of the terminal/atm can be controlled by one or more single-pole, double-throw switches external to the operator panel. When the off-module switches are fitted, the on-module mode switch is inoperative. NOTE: The off-board switches are daisy-chained together and connected to the operator panel through connector J5 as follows:. NOTE: The thick lines indicate the switches set for normal mode. AUDIBLE BUZZER The audible buer can be activated, under software control, to provide automatic echo feedback to keyboard input

4 FUNCTIONAL DESCRIPTION The operator panel service allows selective enabling for data entry of the 20 key keyboard and also supports the following features: Enabling/disabling of the entire keyboard Dynamic enabling/disabling of individual keys Automatic keyboard disable after key transmission Rub out to allow correction of entered data.
