Title: RocGen plus & A1200 problem
Post by: Hinotori on December 10, 2011, 09:43:36 PM

Hi,

I recently got a rocgen plus genlock to use with my A1200 and am having problems getting it to work (with or without an external 12V psu)
When it is connected the amiga lights go crazy blinking on and off and it won't boot up. The power light on the genlock comes on though. I have tried with several different amiga power supplies (including a goliath) and have also plugged a 12V psu into the rocgen ... but sadly no luck :(

Does anyone here have any experience of the rocgen gunlocks that they might be willing to share ?

Many thanks for your time :)

Have you tried it on different Amiga if the problems are the same? This genlock should work on all Amiga models. Its possible that the genlock is causing problems.
I have 2 of those and I don't experience problems like you.

try to feed a stable video signal (like one from a camera) and see if your A1200 boots.

Some genlocks requires it.

hi
many thanks for your replies btu still no luck.
i have tried it with an A500, A500 plus and A1200. I also tried with 4 different amiga power supplies (2 heavy, one light, one goliath) for each amiga and tried with the accelerator removed in the A1200 and still the same problems. The RocGen Plus documentation says that it will operate without a stable incoming video signal by generating its own sync. Without a stable incoming video signal would some genlocks prevent an Amiga from boring ?
I may have a bad unit. I will try a few more combinations.
Thanks again for your help.

Amiga genlocks may be very tricky sometimes (different behaviours with different Amiga models) and yes they can prevent your system booting.

Are you sure that your A1200 and your genlock are of the same video standard? both PAL or NTSC?
