Commodore 1084s-d1 monitor and 130XE VBXE

[+joeatari]

I would like to connect my 130XE VBXE NTSC to a Commodore 1084s-d1 NTSC monitor.  I have a female DB-9 connector installed on the 130XE.  I currently use a GBS8219 RGB to VGA scan converter, and that is working great, but it must have a different pinout than the Commodore monitor because I get a black screen on the Commodore monitor when using that cable.  

Does anyone have the pinout for this monitor?  In my searching I have only found PAL information so far.  If you have already done this and have insight I would love to get your input.

Thanks!

You should be able to go straight from the VBXE to the 1084 with no converter.

 

i use this cable -

Thanks for the info.  I have DB-9 on both ends, so I don't need the HDA 15 VGA.  I use the scan converter I mentioned for a VGA monitor, and that works just fine.

 

I have tried some DB-9 cables I had lying around, but I don't even know if any of them are monitor cables.  They are probably serial cables, and I'm just getting a black screen.  If I can find the pinout for the monitor, I can make an appropriate cable.

I found the pinout for 1084s NTSC, so hopefully that also applies to 1084s-d1.  I'll answer back when I have built a cable and tested it.

I went back to look at the VBXE instructions, and they show CSYNC going to pin 8, not pin 7.  I guess I'll try 8 and then 7 if 8 does not work.

VGA converters will generate around 31 KHz HSync frequency - 1084 monitors only do broadcast HSync frequencies of around 16 KHz.

I'm not using any converters.  My understanding is that a DB9 cable with the right pins connected should be plug and play.

I had no luck in building a cable.  Perhaps the RGB input on the monitor is not working.

Most of the Commodore monitors that support RGB have a switch to change between analog RGB and Digital RGB. You most likely need it to be set to analog RGB.

Yes, I had it set to analog RGB, but no luck.  I tested the composite RCA input, and the monitor does function, but unfortunately there must be something wrong with the RGB input.  Thanks!

Bumping an old thread but this might help someone else out.

 

Csync is pin 7 on the 1084S-P1 ( Philips ), not sure about the Daewoo model that uses the same DB9 connector, they're Amiga spec monitors so they should both be the same. 

 

It's well worth getting RGB to work. Check the orientation of your cables. The PINS are orientated opposite to each other between the male and female end..    easy mistake to make when making these cables up at 3am in the morning. I had the top row reversed on one of the opposite ends
