XTBA DALI Watch Manual Page 3 of 26Product # - 03/2013© XTBA 1986 – 2013Introduction:The XTBA DALI Watch is a tester which is designed to simplify DALIcommissioning and/or testing, identify faults, monitor commands and makelife a little simpler. So if none of the below makes any sense - don’t panic asthe XTBA DALI Watch will help you through muddy waters of DALI – it is not‘Rocket Surgery’.Welcome to the world of DALI. This lighting control protocol can becomplicated as well as confusing - and sometimes just plain bizarre. To add tothe ‘gaiety’ there are a lot of ‘reserved’ commands and a bunch of ‘applicationextended commands’ resulting in not enough command space to fit into 8 bitsso ‘special’ or high commands are needed. They tend to work in a completelydifferent way to other ‘low’ commands and to each other. There is a full list ofcommands and responses at the end of this manual.The terminology has been kept as close to the DALI standard as possible andwhere it can be ambiguous explanations provided.To simplify the commands, commands OFF (command 0) to APPLICATIONEXTENDED COMMANDS (command 255) are referred to low commands.Commands from TERMINATE (command 256) to ENABLE DEVICE TYPE(command 272) are referred to high commands.DALI also helpfully (as it uses less bits) has a channel/address range from 0to 63 rather than 1 to 64 and in order to keep as close as possible to the DALIstandard the XTBA DALI Watch sticks to this format. To simplify in day to dayuse, the default address loaded on a functions entry is 1 rather than 0, so youcan get to zero (if the mood takes you) by pressing the Down or Left keydepending on function type.DALI again triumphs when it comes to levels. The allowable range is 0 to 254,not 255 so in displays that show levels ‘max’ is displayed when the level is =254.DALI Data PolarityDali receivers will work out their own polarity – so you can attach the twocables either way.Advanced MenusThere is a lot the XTBA DALI Watch can do and a lot you might never want toknow about. So in user options you can select Advanced Menus on or off.With this set off some of the more esoteric functions are switched off in themenu system to keep them out of the way.Power OptionsDALI Buss Power - Unlike most other protocols the DALI line is continuallypowered from a D.C. power supply 9 to 22volts (normally 15volts) called ‘DALIbuss power’ across the data pair. The controller sends information byswitching the positive line low - effectively shorting out the line. The receivers |
