- DC input (2V - 40V)
- 15A blade(ATO automotive style) fuses
- 18 DC outputs (2 wire/2 channel Big W style)
- True isolated DMX input (2x RJ45 sockets for looping)
- Jumper for terminating DMX cable
- PCB size is 92mm x 95mm
- Supplied fully built and tested
- Upgrade-able firmware
- Integrated test mode
- Software selectable start address
The + terminals are positive and the - terminals are negative. There are no jumpers required when using different voltages or for any voltage withing the 20V to 40V range.
The DMX2-18 has a 10 Amp blade fuse installed at shipping time. For greater protection you can replace this with lower value types if the maximum current draw from that zone will be significantly less than 10 Amps or conversely if a higher current is required they can be replaced with a fuse up to 15A. The fuses used are conventional ATO automotive fuses.
There are 18 channel outputs; 9 2 wire/2 channel strings.
The maximum load per string is 2 Amps, but the overall limit is 15 Amps.
There are two RJ45 connectors for DMX input / passthrough. They are wired in parallel so it makes no difference which one is used as the input. The RJ45 connection is wired to ESTA standard wiring. See the user manual for details.
If there is only 1 connector in use the termination jumper for the DMX line should be installed as there should always be a termination at the end of DMX lines. If both connectors are in use then the jumper shouldn't be installed. See the user manual for details.
There are 3 small LEDs adjacent to the micro. Red led-Power, Blue led-Mode, Green led-Data -Red led 5V power to micro and electronics -(MODE) Blue led flashing slowly (1Hz ). (DATA) Green led off. Test mode -(MODE) Blue led flashing 10Hz. (DATA) Green led off. Address setting mode. No address yet -(MODE) Blue led flashing 10Hz. (DATA) Green led on. Address setting mode. Address set -(MODE) Blue led on solid. (DATA) Green led flashing 10 Hz. Normal run mode. Dmx packets being received -(MODE) Blue led on solid. (DATA) Green led off. Normal run mode. 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
When you receive your DMX18, it will be set to DMX start channel 1. That is, it will respond to channels 1 to 18. To change the start address use the procedure in the user manual.
There is no need to restart the DMX18 to use the new address. The address can be changed at any time time with power on.
9 Channel mode
There is a switch to allow both channels of each string to be dimmed at the same rate.
The firmware can be updated via the onboard ICSP header. Details of the procedure are in the user manual. A pickit2 or pickit3 is required.
