General help (setting up a Wells Gardner PD279400)

[Rikrok]

I have my first arcade monitor which I'm looking forward to using but I'm quite ignorant on how to get it connected, both power and video. I plan to get some arcade boards but initially it'll just be with my consoles. I have a lot of questions, if you can just answer 1 or 2 please do, or all of them course would be great!

Power is my first challenge.

1. Can someone tell me what the name of this connector type is? It looks like I need to get a 5pin version (and ignore the 2 either side of the middle) and wire that up to an IEC connector so I can use it with a standard power cable.



2. This is probably stupidly obvious but I want to be totally certain, looking at D9400_schem.pdf I found online, it says what they are (hot, ground, neutral) as pins 1 2 3, I can assume pin 1 is on the left and 3 is on the right?



3. I'm in the US so it's safe to assume it's expecting 120V, but when I move back to the UK will it be happy with 240V?


Onto video..

4. It looks like I have two ways to connect video. The one on the left (with the same style connector as power just a different number of pins) says TTL, which as I understand it is a higher voltage standard that I won't be using until I'm connecting arcade boards. I plan to get a transparent acrylic case made for this monitor and want to provide a connecting port out the back of it for when that time comes. What would be a good standard connector to use, I'm thinking db15? Is that vga connector on the right the same but just consumer level voltage instead of TTL?



5. There's a jumper switch round to side which as it say is for selecting interlaced or standard. I assume there's nothing wrong with wiring that up to a SPDT switch? No pitfalls to watch out for?

6. I have all my consoles hooked up through a couple of gscartsw's using CSYNC scart cables (I think maybe one console is using sync on green). Is one of these:
https://www.retrorgb.com/syncslayer-ii-scart-to-vga-adapter.html
what I want to connect that to the vga port? It says it's for 15kHz signals (240p/480i), do I need something else for the Dreamcast, PS2 and original Xbox which can do 480p?

Some other questions:

7. Especially as I plan to put it in a transparent case I'd like to get it as clean as possible. I watched a couple of youtube videos showing spraying them with Simple Green (someone in the comments says Fantastic Mr Bubbles is better as it doesn't leave a residue but I can't find a trace of that online) then hosing them down. It makes me quite nervous the idea of drenching electronics but apparently it must be fine. One thing though - there's a bunch of tape on the yoke and it must be there for a reason, I worry the water will make it come off. What would be your advice? I'm also curious about the three arrow shapes under tape on the tube, does anyone know what that is? Am I better off taking it someone (I found P&L Inc monitor repair here in LA) who knows what they're doing?



8. Finally... I think I remember hearing on a podcast someone say the cooler/more ventilated your monitor the better. When I come to someone making a case for it should I bother having a fan built into it or is that overkill? If it is a good idea, Noctua make 12V, 24V, and 5V fans, is there anywhere I could happily steal that voltage from to power it?


That's a lot of questions so thank you in advance anyone who can help me out with any of it. Also please let me know anything you think I should know but haven't asked about (I do know the big one about discharging it before doing anything).

I found at least the answer to my first question, I think it's a Molex KK 396. Annoyingly the crimpers are really expensive. I guess I can get the solder type connectors though people seem to recommend crimping over soldering.

I'm not super familiar with these newer monitors, but let me give it a shot.
Found this manual:

and this:

1) you answered it
2) Easiest way would probably to find the pin that is connected to the nearby fuse. That would be the hot side.
3) I'm not an electrician, There's probably a ton of info on using US electronics in the UK the manual says it takes 240v, so there's that.
4) The header labeled TTL is where you would get video output from a JAMMA harness (CGA) this is most arcade PCBs. The VGA port is for games that support this output. According to the specs, this monitor should work with damn near anything.
5) I don't think so, it's just a jumper. I'm not sure if the board is designed to have that changed when powered up. My guess would be probably not since it's a jumper and not a switch.
6) I think the SCART adapter would work; definately not my area of expertise, not sure.
7) In my experience, as long as you're GENTLE with water pressure and simple green, the stickers should be fine. YMMV. Obviously you need to read up on how to safely discharge the tube and remove the chassis. This monitor is newer so it SHOULD have a discharge circuit, but I personally would not bet my life on it. Make sure everything is 100% dry before power up. I like to dry my monitors in the sun for a long time, turning them in multiple positions to make sure no water is trapped anywhere.
8 ) There are so many ways to put a fan on it, probably the easiest way is just to use a A/C fan. Monitors are designed to run all day, but not in a small enclosure. Definitely make sure you have vents and cooling if you do that.

Also: You don't have to spend a lot on molex crimpers, checkout: https://www.greatplainselectronics.com/ they have everything you need.

duffcon thank you so much! That's a huge amount of help, I'm in a lot better position now. And that final link- they have the crimpers (including the connectors) cheaper than loads of googling ever found. Thank you thank you

I noticed in the manual:

"Universal AC Input Voltage.
Power supply operates on 90-240 VAC at 60/50Hz for use all over the world."

Also note that the rule of thumb is if earth ground is on the input on the chassis, then you don't need a Isolation transformer. This is generally the case for newer monitors; I believe most multisync monitors are newer and this also applies.

Good to know, thanks

Those arrows under the tape are magnetics, don't remove them. I have exactly the same monitor and it works with pretty much everything. About using it in UK just make sure the voltage frequency in UK is covered by the monitor spec.
