It is strongly recommended that you use the same power supply for the board power and output loads to prevent any issues with the clamping diodes built into the board Ground is shared between the processor supply the output supply and RS 232 Common The power supply side is used to clamp inductive spikes on the outputs Host control programming RS 232 5 wire TXD RXD CTS RTS Ground or 3 wire TXD RXD Ground cable supplied Selectable Baud Rate 75 115200 Simple text commands allow use of any terminal emulator program for setup Afree terminal emulator program Cool Term for use with Windows OS X and Linux may be downloaded from our Support web page Your program timing script is created and edited using a standard text editor or any spreadsheet program 4000 program steps Program and settings memory maintained without power and may be changed at least 1 million times 1mS 0 001 Second timing resolution Multiple programs may be stored in memory you can switch between them with the RS 232 host Nested looping and conditional jumps allow easy control of complicated sequences Debug and manual operation commands to get your installation working quickly Easily controlled from any lighting control HVAC PLC or microcontroller that has an RS 232 output If not used while running the CTS and or RXD pins may be used for switch or logic inputs to control the program An example would be a push but2. Comment This may appear anywhere on a line including after a command This character and anything to its right will be ignored completely other than it counts towards the 250 maximum characters you may send in a single line Your comment will NOT be stored it is for your notes only Prints out a list of all of the above commands 22 Programming Commands All Programming Commands are preceded with an asterisk to let the sequencer know it s a program step Following the asterisk is the step number this is a fixed location in memory where the program command and data will be stored When a program starts from either power up or the RUN switch being thrown it will start at step 1 so you should always have something there After that steps are executed in order unless you have a Jump command For special applications you may have multiple programs loaded into memory and execute any of them by using the Run command followed by the step number that is the start of that particular program In this case you might want a default program start at step 1 that will execute when the RUN switch is thrown Or if you Erase step 1 then the RUN switch will have no effect as it will try to run that instruction and immediately halt Other than step 1 all other program locations are equal They all execute at the same speed and jumps between them take the same length of time Feel free to leave spare space in your program for future edits as long

5. as you remember to skip over this spare space with a Jump if you only have one or two you can also use a Delay of 1 for each You may change commands while the program is running and the new step will overwrite the old one in memory This may delay the next program step from starting by a fraction of a second if your change happens just as another step is about to execute Since the settings Title Speed Force etc are stored in program memory changing any of these may also cause a short pause Overwriting an instruction with a Delay of 1 will allow testing your code without that instruction Overwriting with a Jump will allow you to skip a whole section of code All commands have a delay from 1mS to 2 billion mS over 3 weeks 1 second is 1000mS so a delay of 1 1 4 seconds would be 1250 If a command doesn t allow you to set the delay then it is automatically 1mS Do NOT use spaces decimal points or commas in a number Each command below has to start with an asterisk and a step number so the Sequencer knows to store it in memory instead of trying to execute it D Delay This should always be followed by a number indicating how many mS the program is to pause J Jump In most cases this will simply be followed by a step number After a 1mS delay the program will continue executing at the step number given If there is a second number following the step number that isn t zero that is a conditional test The conditional test ch

9. up in step 2 If count is still above zero then the program jumps back to step 3 the step AFTER the L When the count is finally zero the program continues on to step 7 which simply jumps back to step 1 to start over The above program can be very useful but sometimes you might want to have a loop inside of a loop Never fear you can nest loops up to 4 deep inside each other Before viewing the steps you should understand what a Stack is Think of this as a stack of notes in a small box You can only see the top note and you may add a note by placing it on top of the stack or delete one by removing it from the top You may also change the information on the top note We call adding a note PUSHING and removing a note POPPING There s one additional limitation if you PUSH a fifth note on top of the stack the bottom note disappears so there is never more than 4 notes in the stack This stack is used to keep track of the loop count and the starting step for the loop Indented lines to make it easier to follow 115 PUSH count 5 amp start 2 for loop A 213 PUSH loop B inside of A 3 L 100 PUSH loop C inside of A B 4L6 PUSH loop D inside of A B C 5 S Ob1 55 turn on output 1 for 55mS 6S 01 all outputs off 7N Next D jump to step 5 or POP 8 S 0b10 12 turn on output 2 for 12 mS 9SsS 01 all outputs off 10 N Next C jump to step 4 or POP 11 S 0b100 100 turn on output 3 for 100mS
10. when using the debug command If for some reason you can t use RTS CTS handshaking on some computers it simply isn t there then set your terminal emulator program to either pause after sending each line for 100mS or to wait for the next prompt that would be the character gt If using end of line delay in CoolTerm you would also have to set the end of line characters to Od Oa zero D space zero A In CoolTerm under Connection Options there s a tick box to enable it to handle the backspace key that should be turned on Other terminal programs may have a similar option Notes for people writing code on their host controller to talk to the Sequencer e CR Vr is the end of a line not NL An unless you ve set it as an alternate line end character e Data is echoed as received you must receive this without setting CTS as busy Forgetting to flush a receive buffer is a common error e Any characters with errors are discarded and not echoed e The prompt is sent as r n gt but if there is an alert the alert name will inserted such as r nForcing gt this alert indicates that either a DIP switch is on or the Force bits are enabled in the settings The following section is to be used to reset the the baud rate to 9600 if you changed it and forgot what you changed it to BAUD Reset Turn off the power to the board 2 On the upper right of the board is a group of 10 holes with a box drawn around th

14. S in your terminal program Data transfer is full duplex in that received characters are echoed back to the host controller as soon as the firmware fetches them from the buffer If handshaking is ON and the CTS line is unconnected or inactive ground or negative the Sequencer does NOT send any characters to the host computer It stops receiving commands as it waits for permission to send the previous response If handshaking is set to OFF or CTS is tied high then responses are always sent regardless of if the HOST is ready Any White Space received before the first regular character of a command is discarded After this all characters up to about 250 are stored until a CR RETURN is received Corrections are made by using the backspace key this will not back over any leading White Space that was discarded Command processing starts when a Carriage Return RETURN ENTER CR or r is received There may be any amount combination of white space between portions of a command line as long as it all fits in 250 characters The following commands are all treated the same 1 s 5 100 yee te SB 100 yn 1 US 5 100 Almost all commands may be entered in UPPER or lower case the only time it makes any difference is with the Title and UPDATE commands There is an optional debug command that sends data to the host that can be handy for complex programs Note that if handshaking is ON and CTS is inactive or open your program will freeze
