Powering a Hantarex monitor

[wmfms]

I've just got hold of a NeoGeo MVS 6 slot JAMMA cab, with a 25inch Hantarex MTC 9000 monitor. I'd like to set it up w/ my xbox for MAME (thanks to this forum I now know how to get the xbox RGB working on an arcade monitor - thanks for the great posts guys).

My question is, what sort of power supply should I use to power the monitor? (Unfortunately the original PSU is missing). I've taken a photo of the connectors at the bottom of the cab, the guy I bought it off mentioned that I could use any old PC psu... is that true? If not, what type should I be looking for? Is there a method to wiring it up, or is it literally plug and play? Any advice is much appreciated.

Thanks WMFMS

I'd check the manual from here

I'm guessing (YMMV/iam not responsible for your actions) that you'll need AC mains power routed through an isolation transformer -> but I don't really know... but maybe it;ll show you in the manual (RTM!)  or someone more knowledgeable than me will expound upon the details...

good luck! (lucky bastage! you going to sell/trade the neo geo 6 slot board?)

PS the bob roberts site has  a good overview of basic/standard cab wiring (including the iso transformer) *shrug*

Upon glancing at the manual I linked you to, you definitely need to use an isolation transformer...

Hey Rampy,

Thanks for the reply and the links! I've had another look at the insides of the machine. Of the three power cables I pictured in the last post, the bottom one with four wires (brown/yellow/orange/red) is coming straight from the monitor. I found this JAMMA power supply on ebay -



Which has the right connectors and would take all three power cables perfectly. Having looked at Bob's page I'm even more confused... Thing is, this cab must have had an isolation transformer in it at one point, but I haven't got a clue where it would have been placed inside, or how it would be wired to the JAMMA psu in the picture, because it looks like the monitor cable would plug straight into it! Any ideas?
 
Thanks for your patience with a total newb,

Your pics aren't showing up my friend...  probably because your host doesn't allow remote linking... If I go directly to the url

http://www22.brinkster.com/wmfms/i-1.jpg I can see them though...

I thought bobs diagram would make things clearer for you, cuz it did for me =P  oh well...

I'm not *that* experienced with arcade machines/monitors to feel very comfortable giving you advice... (where's mamefan, PaigeOliver, and Mr.Arcade when you need them =P )

The isolation transformer should be hard to miss in your cabinet if it is present... I assume you'd see it mounted near the bottom of your cabinet...  It's probably a good 4" by 3" rectangler cube...  give or take...

let me see if I can find a better illustrated guide for you and i'll edit my post later...

PS I'm a little confused by the powersupply you've found on ebay myself... does it have the iso transformer built in? i.e. an all in wonder type switching powersupply weird...

[rampy]

A few questions and a comment...

1. do you intend to preserve any use of the cabinet to ever go back to a NEO-GEO or other JAMMA arcade pcb game?

2. can you take a pic of the back of the monitor and the bottom of the cabinet?

If you aren't going to put a JAMMA game back in there ever, there's little point in putting another switching powersupply in the cabinet.

You *do* need an isolation transformer which you wire up between the AC 120volt mains (the stuff that comes out of the wall, assuming you are in the US) and the monitor (which takes 120 volts as well, BUT for safety sake REQUIRES an isolation transformer in the "middle".

You wouldn't/shouldn't have to deal with all those molex's/original wiring...

I'm gonna try and find some good illustrations for you.

Here's a very basic article but neglects to talk about iso transformers... (but it's good for lingo/background/familiarity)

you can of course buy an isolation transformer from the real bob roberts, or happ controls... you might be able to pick one up from a local TV repair place, or gasp evil radioshack... *shudder*  (working on finding a useful diagram for you... )

[rampy]

Note: this is really dumbed down... basically stripped out all the extras... you still might want to wire up the marquee light etc... but for simplicity sakes thought this would help...

One semi-important note:  it seems your monitor has a built in degaussing circuit (which is good...) but it seems to require 220volts to also be wired to your monitor to power that... usually a fancy isolation transformer can do both the isolation and "step up" the voltage to 220 on another set of leads, but you are really stretching the limits of my hands on knowledge of this stuff...  i.e. ymmv I am not responsible for your actions =P

I wonder if you can skip the 220v and just not have the auto degaussing circuit (although that is important/handy)

Hey Rampy...

Thanks again for the swift replies. My main interest is to get the xbox working on it, rather than keeping it for JAMMA PCB's or MVS cartridges (sad I know - but the cab only cost me

Sorry bud... I haven't got the six slot board or PSU, the seller literally gave me the cab and the monitor. I might be seeing him again soon though, so I'll ask if he's got one (This guy has over 80 cabs spread over 3 full garages and most of his house! Bet his wife goes crazy...)

That's ok nvr mind about my neo geo fixation, I don't *need* any more stuff, or so my wife says =P

I hope the above info gave you enough to work through your monitor issues.  I hope there isn't any drastic difference in UK wireing than US wiring that'll goof you up (be careful!)

If you end up using a PC with (instead of the x-box, or concurrently) be sure to check out the arcadeVGA card from ultimarc.com.  It really makes things easier.

Good luck!

Hi there and sorry to reply to old topic, but I have good reason (at least I think so

So I bought Jaleco Big Run Rally upright cabinet, which has Hantarex 9000 E display. Everything works, I 'm going to put mame computer inside the cabinet. I would like to maintain the ability to play the original game.

I was thinking of installing On-Off-On switch to the control panel, under the steering wheel. One side is for the original game, other side for the mame computer. Both sides of the switches would turn on the arcade monitor.

I'm going to order Ultimarcs video amplifier for connecting the arcade monitor to my mame pc (which will have GeForce 8400 GS) and install soft15Khz. I have done this with mille miglia cabinet, and it worked after tinkering with it

Question: Can I start the monitor and mame computer at the same time, or will it ruin the Hantarex 9000 E? With my mille miglia, it was not a problem, I powered both simultaneusly, and monitor showed garbage from about 30 seconds. After that, 15 khz display, but it did not damage the display unit. Can I do the same and not risk damaging the hantarex? If not, what is the proper way to power up the monitor? Somekind timed relay?

13 year old bump for this?  Why didnt you just start a new thread?
