In addition to unit status, unit timing, and active timer countdown to aid in intersection setup, monitoring, and troubleshooting, the CU monitors its own operation automatically and continually verifying memory and processor operation with additional capability to verify inputs, outputs, keypad, and display Unit To Printer The CU timing and operational data, preemption data, coordination program data, time base data, system data, and reports are individually transmitted to the printer. The printout is in a format easily understood by a trained traffic oriented person. The unit to printer transmissions shall not interrupt normal CU operation. The CU provides for asynchronous serial data communications with RS-232 signal levels, X-On/X-Off handshaking protocols, variable word structure, transmit and receive ASCII coded Bits Per Second serial data Unit To Unit The CU timing and operational data, preemption data, coordination program data, time base data, and system data are individually transmitted to/from another CU. The unit to unit transmissions will not interrupt normal CU operation except when Ring Structure data is changed. When the received Ring Structure data is different from that running, the receiving unit automatically reverts to the Start Flash interval. The receiving unit times the Start Flash time and resumes normal operation in the programmed Initialization interval. The CU provides for asynchronous serial data communications with RS-232 signal levels to transmit and receive Bits Per Second serial data Unit To Personal Computer The CU timing and operational data, preemption data, coordination program data, time base data, and system data are individually transmitted to/from a personal computer running the appropriate software. The transmissions will not interrupt normal CU operation except when Ring Structure data is changed. When the received Ring Structure data is different from that running, the receiving unit automatically reverts to the Start Flash interval. The receiving unit times the Start Flash time and resumes normal operation in the programmed Initialization interval. The CU active status (Ring Timers, Coordination Timers, Preempt Timers, and Time Base Current) are individually transmitted to a personal computer running the appropriate software. The CU report logs (Local Alarms, Communications Faults, Detector Faults, System Detector Log, MOE Report, and Speed Report) are individually transmitted to a personal computer running the appropriate software. The CU provides for asynchronous serial data communications with RS-232 signal levels to transmit and receive serial data. 1.3 PROGRAMMING The CU provides means to enter and view variable data, view current status, and view the event report. The CU prevents the alteration of keypad set unit variables prior to the user having entered a specific code. This "Access" code is also user programmable via the keypad. There is provision (user entered code) to disable the requirement of entering an access code before alteration of keypad set unit variables Entry The method of entering CU variables is by: 1. An integral keypad on the face of the unit, and/or 2. Via a RS-232 Interface and a Personal Computer Display The method provided to view CU variables, current status, and the event report shall be by: 1. Integral Indication on the face of the unit, and/or 2. Via a RS-232 Interface and a Personal Computer The method provided includes a simultaneous display of up to eight lines, 40 characters per line of ASCII text (HEX 20 through HEX 7A) Security The CU maintains user programmable variables in non-volatile memory to assure continued proper CU operation with return of power after power loss. The CU continuously monitors memory contents for errors. If an error is found, the CU immediately ceases outputting signals to the processor monitor and thereby reverts to flashing operation. Manual SEPAC Actuated Signal Control Software FEB 02

16 Page Backup The CU contains a reserve data base of all CU keypad set variables stored in Read Only Memory. It is possible for an operator to activate the reserve data base by loading it into memory through a simple procedure involving front panel controls.

17 FRONT PANEL - BASIC Page 5 2 FRONT PANEL - BASIC A Controller Unit with EPAC300 Firmware/Software (CU) may utilize an alpha-numeric Display and multi-position Keypad to provide an interface between the user and the CU. The CU Display becomes active on power-up and remains active as long as power is applied to the unit Front Panel Summary The CU Display provides true visibility into program entries, timers, and the instantaneous status of intersection operation. Related parameters are visible simultaneously making verification straight forward and eliminating the need to write the data down and/or scan back and forth in order to remember what the parameters are. PROGRAMMING via the front panel keypad and display is easy and error free due to the English Language Menus with easy 1 digit selection and automatic forward and backward progressions. Within a menu, each parameter may be viewed and a cursor movement to that parameter makes changes easy and error free. If an error is made during programming, the operator will see messages such as "ENTRY OUT OF RANGE" on the bottom line and the cursor remains at the entry parameter waiting for proper activity. Attempts to enter parameters outside acceptable ranges are rejected on occurrence without destroying the existing values. As a reminder, the upper left corner identifies the display and the lower line identifies cursor control and forward/backward menu selection. HELP is available in each screen! The "+" key has been designated as the 'HELP' key. Pressing the "HELP' key will open and close a HELP screen. A HELP screen provides information based on the field where the cursor is located when the HELP is called. Closing the HELP screen will return the user to the same field. HELP screens are available in all screens except ACCESS, ACTIVE STATUS and REPORT screens Front Panel Entry Data is entered or displayed by selection from menus. The menus are arranged in a hierarchy consisting of a top level menu made up of sub-menus which may or may not consist of more sub-menus. The following parts of this section are devoted to describing the key combination (input), the window display (output), and the purpose of each menu and sub-menu. This section discusses the highest level menus first and then discusses each sub-menu. The "Main" Menu represents the highest level menu from which the user can choose. Pressing the "F" key a number of times will always return the user back to the top level menu. Each menu and sub-menu's purpose is discussed along with the correct keypad selection. Front panel entered data is cross checked on a priority basis. To enable the check to have maximum value and to minimize error messages during entry, it is suggested data be entered in a Unit, Phase, Coordination, Time Base, Preempt, and System sequence Front Panel Timeout There are two different types of time-out associated with the front panel: Except when perpetual access is programmed, access is automatically turned off approximately ten (10) minutes after either: 1) Access was gained. 2) The last change was entered. The front panel back light is automatically turned off approximately ten (10) minutes after the last front panel activity Main Menu The following menu becomes active on application of power to the CU and is the basic starting point for all data/status review and/or entry.
