light master xl

[joelstraman]

How do i use the analog outputs 8 pin with on a light master 12 xl. The manual does not reference them at all. awill they drive an \act 6 dimmer pack and a Pulsar 6 channel dimmer pack?

 

thanks dave @ apex studios

Hi Dave,

The analogue 8 pin DIN connectors on the back of the console will control 6 channels, using a 0 to +10v signal. 

This information can be found on Page 35 of the manual, attached to the article below...

I believe Strand ACT6 dimmers have the ability to switch between receiving a 0 to +10v signal or 0 to -10v signal, so ensure this is set to receive a positive voltage. You’ll then be able to connect the console and dimmer together, and have intensity control of the dimmer channels.

Pulsar dimmers are usually wired differently, so I would recommend consulting your Pulsar dimmer’s Manual to determine the control pinout.

Lightmaster consoles use the following Output pinout...

Pins 1-6 are channels 1-6

Pin 7 supply voltage from the dimmer  

Pin 8 is Ground

Hope this helps, if you have any queries let me know.

That is true of "newer" ACT6s however early Strand equipment (including ACT6 models from the 1980s to early 1990's) had a fixed 0 to -10V control signal. This requires an "inversion" circuit to change the 0 to +10V to 0 to -10V control voltage.

This link discusses such a circuit for Strand dimmers using 0 to -10V control voltage, if you are capable of some straightforward low-voltage electronics construction:

(The circuit shown is for 2 channels. Note the need for a power supply to provide +/- 15V too).

Also regards the pinout of the DIN8, Zero88 and Strand use the same pinout - pins 1-6 are channels 1-6, pin 7 is a desk supply (output on a dimmer, input on a desk), and pin 8 is 0V/GND. Don't connect pin 7 unless you know it's the correct voltage for the desk. For example Betapacks output +20V (switchable to -20V) but the ACT6 may output -15V which would be useful to power your inverter circuit above.
