Sirius24 Chili dimmer prob

[CHIPS]

I have an elderly and loved Sirius 24 which works fine via DEmux48 and Betapack 2.

 

In a recently fitted school system fedding into Chili dimmers via Pulsar DMX splitter there is not a trace of a signal. The School Jester 48ML works . Has there been a change of DMX spec or (no names no pack drill but happened in a nearby school) is it possible for the Jester to work with an incorrectly fitted dimmer system ??

From experience - are you using the same cable to connect your Sirius as the Jester?

 

We've come across some installations in the past where there's been a 'special' cable which was pin inverted or non-standard wiring... Some Pulsar installations use the shield of the XLR's as ground too but this might indicate a 'special' cable involved.

 

It would also be worth checking the Chilli's to see if there's any patching going on as well - some installations use it with multiple spaces to do channel allocations 'correctly'

 

Without being next to it, DMX problem solving is going to be long winded...

I tried all combinations of leads available - certainly my lead with the jester - I'll double check with their lead to my board. Will check patching today but the Pulsar LEDs were not even lighting to show activity. I can run this show from their board but am not happy that the installation is correct. The contractors were general electricians; solid citizens but clueless re DMX. I also intend to test with the demux48 starting the chain in case it's my system that is unique! Thank you. A lot of rigging to do today so testing will happen when there is time.
