Extron Crosspoint TTL Output Conversion

[Xer Xian]

I'm actually using 13 outputs right now (8 monitors, 3 converters which I loop back into the Extron Crosspoint Ultra 1616 HVA, OSSC/XRGB-mini, 1 test output line, and plans to use ~2 more for some other converters), but not all use BNC to SCART cables like you linked to. Right now I would need 4 of those: OSSC, XRGB-mini, ShinyBow SB-2840, and need one for the test line as well.

Holy cow Doc

But..

Spoiler

Does sunlight still reach that far into the rabbit hole?

I will probably just open up the SCART head and put in a 470 ohm resistor - I believe that's on pin #19??? on these BNC to SCART cables running off the output side of the Extron.

for BNC to male Scart it's pin 20, for BNC to female Scart it's Pin 19. For Scart to BNC this reverses.

You should see my diagram I had to made to keep all this crap straight with the converters looping back and forth - that is definitely down a deep hole (simple to me now, but figuring it all out logically took a bit). I'm just happy my Extron Crosspoint keeps it's presets for me so I only have to set it up once.

If you're talking about the sheer number of monitors, I've slimmed down my collection majorly the last couple months! Going down to a 20" monitor for Player 1, Player 2, and a TATE; then a bunch of little 8" ones so I can display every system I own on a different monitor at the same time for a little fun conversation piece when I have people over.

for BNC to male Scart it's pin 20, for BNC to female Scart it's Pin 19. For Scart to BNC this reverses.

Still always confuses me... (think I had to switch pins for audio too...)

Luckily in your case, the cables are already built, so just add the resistor to the sync pin that has a wire connected. It's much more of a pain for people making their own cable that have to guess which pin the first time, then go back and move the wire if they got it wrong.

Also, keep in mind some equipment works fine with TTL (most PVM's and BVMs'...check the service manual to be sure) and some equipment actually require TTL, such as some Extron boxes. Maybe in your case you can skip adding it to some of the outputs.

Just added a 470 ohm resistor to my output side BNC to SCART cables - very easy and my Shinybow SB-2840, OSSC and XRGB-mini are now protected! I don't have equipment to measure the output so but those devices seem to work normally so that's all I can ask for.

What about those BNC attenuators I linked to above? If those, from a technical standpoint (far above my paygrade lol would work on the Extron Crosspoint on the output sync line...that would be a SUPER easy, non-solder solution which EVERYBODY using an Extron Crosspoint would love to have. Simply put it on the sync line for those sensitive devices which need 75 ohm and you would be set. No soldering, no opening SCART heads, no reading pinouts (which is more than many of us know how to do). Literally plug and play. Anybody have any comments on those?

I can say I would very much like a few of these, assuming they do what we need them to do, and I agree that they'd be super easy to use. That said, which one would be appropriate in this application? Are we going to need to buy them, crack them open, and then insert our own 470Ohm resistors?

Hey guys, I'm outputting from a Crosspoint 128 to both a PVM 20M2MDU and a Ikegami HTM-2005r.

Here is the cutout from the 20M2MDU manual:

EXT SYNC IN
BNC connector (×1)
4 Vp-p, ±6 dB, sync negative

From what I understand, that means it should be fine?

Also, from the Ikegami, this is from a similar model, but not exactly mine:



I'm confused about the "HDTV" portion - is the manual stating that it will accept a lower voltage on the sync line for HDTV images than for SDTV? Also, is the Ikegami ok with the Extron output in SD too?

Sorry guys, I don't know too much about this and would appreciate the help.
