Has anybody successfully connected an old 3130 genlock board to a Lenco sync generator/NTSC encoder? The Lenco generator has six outputs: BF, SY, HD, VD, BL, and SC.

Actually, all this other stuff is the NTSC signal broken into its various bits and peices, such as Horizontal Sync, Vertical Sync, Blanking, etc... So, hook Red on Iris to Red input on the Lenco, Red out on Lenco to the Red input on your monitor. Same for Green, Blue and Sync. On our CCE-850, inputs are the bottom row of 4 BNC connectors, outputs are the top row. Hook "Video Output" on the Lenco to Video input on a NTSC monitor, and it should work. Works on our 2400 & our 3130. >Eric Pepke INTERNET: pepke@gw.scri.fsu.edu -- Chris Shaw University of Alberta cdshaw@alberta.UUCP CatchPhrase: Bogus as HELL !

Works on our 2400 & our 3130. You misunderstand. I thought that my mention of the words "genlock" and "sync generator" should have made my problem clear. My problem is not in getting the RGB into the encoder and producing an NTSC signal. I can do that using the internal sync matching just fine, but the quality is low, and I intend to try the genlock method. My problem is getting the sync output from the sync generator into the IRIS. I only mentioned the outputs that are relevant to that problem. So, perhaps I can state the problem in a more detailed fashion. The Lenco PGE-843 is a combination sync generator and NTSC encoder, which means that it does two things--generate sync and encode RGB into NTSC. My problem is with that half of the box which generates sync and does not extend to the other half of the box, except inasmuch as there probably exists an internal connection to ensure the correctness of the phase of the chroma information. The sync generator has six sync outputs, which are sync components, and the IRIS Genlock board has two sync inputs, labeled J7 and J8, which are probably the same as what are in other places called HSYNC and VSYNC. I suspect that the solution is simple and merely involves wiring up a bridge to combine the six sync outputs of the generator into the two sync inputs to the IRIS Genlock board. However, I do not yet know the composition of said bridge, and my ignorance is compounded by the fact that my documentation to the Genlock board was lost during a move. Keith Seto, manager of the technical support group at SGI, has kindly agreed to send me a copy of some documentation, so I should be well on my way to solving this problem soon.
