Mode JODE a E Dmx start address table Connections Dmx Data There are 2 RJ45 dmx sockets on the board These are designed for loop in and loop out If the AAHMega60 15 the last dmx device on the dmx cable then the signal should be terminated with the termination jumper Basically if only 1 cable 1s plugged in Li i Ta to the dmx sockets then the termination jumper should be 5 dn installed If both sockets are used then the termination On jumper should be left off LE There are 2 sets of jumpers adjacent to the dmx sockets These allow for connection to either ESTA or Light O Rama LOR networks If the next device connected to a given socket is wired according to the ESTA standard then the 3 jumpers would be installed in the ESTA network position If the next device is a LOR device USB dongle CTB16PC etc then the 3 jumpers would be installed in the LOR position The relative positions for the 2 networks is marked on the pcb nw DC Power Input The 4 large 2 way green connectors are the DC inputs from your power supply Each of the 4 zones of I5channels can use a separate power supply or you can feed them all from one common power supply Separate wiring back to the power supply for each of the zones is recommended to minimise voltage drop The V terminals are positive and the V terminals are negative Any DC voltage in the range of 5V to h 42. received MODE Blue led on solid DATA Green led flashing at 1Hz Incomplete dmx packets being received At least the first dmx packet is received but there is a problem with the stream before all 60 channels have their data All outputs will be turned off This error has been disabled on firmware version 1 2 MODE Blue led on solid DATA Green led off No dmx data Test mode takes precedence over normal running so errors status message other than test mode won t be displayed if in test mode Start Channel DMX START The start channel is set via 9 dipswitches The channel is set in binary by turning on the relevant switches DMX addresses can be anywhere between 1 and 512 The address of the is af g k a AAHMega60 can be anywhere in the range of 1 to 453 a start address of 453 uses the EX 12345 addresses from 453 to the maximum 512 If the address is set outside of this range an error 15 Ear indicated via the 2 status leds See Status Leds The start channel can be changed at any time The start address can be calculated by adding up the totals for the switches that are on For example 64 16 1 would give a start address of 81 A table is provided later in the manual that lists the dmx start addresses f Nm i JM p B ws E Fi k Test Mode There is a switch on the same bank of switches which places the control into a test mode In this mode a test program runs and all 60 outputs are cycled through This mode a

4. 0V can be used The negative V terminals are commoned s between the 4 zones so this must be taken into account when wiring up to the power supply supplies Each of the 4 zones has a standard ATX automotive fuse adjacent to the power seal The AAHMega60 comes supplied with 10A fuses _ fitted Fuses up to 30A can be used It is recommended changing the fuse to the closest size for the total current that the E zone will be supplying It is recommended that the dmx cables not be connected when changing from LOR to ESTA as an accidental short circuit may Positive Terminal damage the dmx transmitter Negative terminal OC e Dimmer Outputs There are 60 channel outputs 30 per side with each side divided into 2 zones Each side can be run at the same or a different supply voltage Any DC voltage in the range of 5V to 40V can be used for each of the banks The maximum load per channel is 5 Amps but remember that the overall limit per bank zone of 15 outputs is 30 Amps This means that you can t turn on all 15 outputs of a zone with the maximum load In reality this should not be a problem as most loads will be less than 2 Amps There are 60 dimmer outputs which are in banks zones of 15 with each zone of 15 fused separately Each group of 3 outputs 15 grouped into 4 terminals These are the 3 outputs and a common positive RGB lights with a single common anode should have the common wire connected to the terminal

U 5v PSU Firmware Updates Firmware update can be loaded via the onboard USB socket or if necessary through the ICSP header with a Pickit3 pic programmer Pin 1 of the ICSP header is marked on the pcb and is shown to the right Ensure the pin 1 of the header is aligned with pin 1 of the programmer If the firmware is being updated it is recommended to remove the fuses of any channels that are dimmed down to less than 100 with the Zone Volts jumpers as there is a possibility that during the firmware update process the leds may be turned on with 10090 voltage Under normal circumstances all leds are turned off and should remain off during the firmware update process Power Input 6 Plug your PicKit 3 into a spare USB port then start MPLAB Once it has loaded click Configure Select Device to bring up the device selection window From the device drop down list select PIC18F4455 and click OK A dialog saying New firmware must be downloaded for PicKit 3 to work with the part selected may pop up at this stage If it does click OK and wait for MPLAB to download the programming firmware to the Pickit 3 You will see some activity in the PicKit 3 tab of the output window for up to a minute or so When MPLAB is ready you will see PicKit 3 Connected and possibly an error stating PK3Err0045 You must connect to a target device to use Pickit 3 This is not a problem and just a warning that the PicKit 3 cannot see the chip yet Then cl
