The main reason for not using flash in production is cost We need to have two prototypes ready for the end of the week so was given the task to check both prototype PCB boards making sure there are no broken tracks This was achieved using multimeter in buzzer mode using schematic as a guild checked every connection Next after it has been confirmed that the PCB are correct started to populate both boards with all their components hence getting some much needed soldering practice After the boards had been finished tested them Connected to 12V power supply connect RX and RX to TX and TX of the Access 4000 and switched on noticed straight away that a view LED s where constantly on using mulitmeter it was discovered that a couple of BS170 transistor BEng Hons Electronic Systems Page 43 98425145 Sunday 20 July 2003 Industrial Placement Logbook Colin K McCord where dead Always a circuit between collector and emitter Replaced faulty transistors and tested again both prototype SCI Annunciation where working There was a slight worry the voltage regulator will over heating mounted to small heat sink a high voltages left the SCI Annuciator running on 28 Volts for 6 hours to seek how hot this voltage regulator got After 6 hours there was a small amount of heat but the heat sink seamed to be doing a good job in displacing the heat and the tested was seen as a success Next using AutoCAD R14 design label strip

28. 32MB of RAM S19 files worked fine but had a problem with the text files At about 50 the communication slowed and the Access 4000 control panel timeout and load failed At frist did not understand why this was happening but then discoved that was incrementing the process bar after every byte hence creating a delay between the bytes The reason why the S19 files works was because there is a delay between blocks when waiting for the ACK hence the processor was able to catch up Once it was discovered what was causing the problem the problem was easily fixed The solution was to change to step size of the processor bar to 50 and step it every 50 bytes instead of every one This solution worked fine Although there was no problem with the S19 files it is bad and wasteful programming to increment the process bar after every byte The process bar was updated after every block hence no delay between bytes within a block Before the changes where made loading S19 files on my computer PIII Windows NT used 10 of the processor it now uses 2 of the processor Before the changes where made loading TXT file on my computer PIII Windows NT used 45 of the processor it now uses 4 These values where taken from the Window NT Task Manager Created a small help file using Help workshop describing how to operated the program After a couple more hours of testing passed the program file to another team member who will test it
