2100 in 1 - Isolation Transformers?

(1/2) > >>

TNHANK:
Greetings, My first post
I just built (or finishing) my 2nd Cab
I have built a 4 player cab and I am using the 2100 in 1 Games Family PCB
It has a link to use players 3 & 4.  I assume i just hook another Jamma harness to the "linking unit" chip board and wire player 3 and 4 in addition to the +5, +12, and Ground power cords.
I read on some forum that an isolation transformer should be used.  I have one on my 1st cab but set this one up without one.
If I am using a LED Monitor are Isolation Transformers needed?
Also anyone hook up one of these 4 player Games Family units before?
Do I need 2 differnt Power supplies (1 for player 1 and 2 and 1 for player 3,4) (in addition to the ATX running the CPU)
It works fine as 2 player trying to get the 3 and 4 up.
-Hank

Malenko:
Isolation transformer has nothing to do with the PCB you are running. Its required to isolate the voltages for the monitor. Some monitors need them , some don't. LCD monitors do not.

Can't answer the player 3 and 4 question, I dont use low quality bootleg PCBs (cept the 1 time my friend wanted one in his bartop)

From the description :


--- Quote --- It can support up to 4 players via a remote 3/4P Interfacing card (which connects into another JAMMA cabinet so TWO cabinets are LINKED TOGETHER!).

You will need an extra ATX power supply for this PCB (not inclued).

ANd from another site selling them :


--- Quote ---It can Support up to 4 Players via 4 player Connection Cable, which are able to link up together with TWO Cabinet.
--- End quote ---

SO if I'm reading it correctly it can not be used for a single arcade setup but is designed to play players 3 and 4 on a separate cabinet (like the Nintendo VS. 4 player) where the display is mirrored and players 1 and 2 play on one setup and players 3 and 4 ply on a separate setup. So it needs a second Jamma connection to wire players 3 and 4 - not sure how it connects them but evidently it includes an interface card that probably runs from the second Jamma connector to the first ( ie. players 3 and 4 buttons are connected to a second jamma connector which then connects to the adapter that connects to the 2100 in 1 PCB.   :dunno

From this pic :
Removed Pic per rule 5 - Since it had watermark listing website selling it !

You can see the second jamma connector on the adapter PCB - so looks like players 3 and 4 are wired    into that Jamma Connector and then the adapter hooks to the 2100 in 1 PCB with the 2 wires running from the adapter back to the 2100 in 1

PL1:
OP PM'd that his system is up and running now despite the crappy documentation on these  :censored:  things.

He confirmed that to rig a single XXXX-in-1 for 4-player operation:

  * The computer board is powered by an ATX power supply 20 pin.

  * The main JAMMA board connector (P1/P2) gets wired exactly like a normal JAMMA harness with +5v/12v/Gnd from an arcade power supply.

  * The P3/P4 daughterboard connects to a JAMMA harness (P3/P4 controls wired same as P1/P2 controls) and with +5v/12v/Gnd power from the arcade power supply. (One supply powers both the main JAMMA board and the daughterboard)

Connecting power to the P3/P4 JAMMA isn't in the documentation, but is mentioned in one vendor's video.

Sorry, but no link to the video because of Rule 5. (The account is named after the vendor)
