eliminating table wires

[Casey]

how does one with auto scoring eliminate the table wires? We don't have many problems with them but when one does break internally it can kinda be a headache. Is it a fairly simple modification?

Re: eliminating table wires

It's very easy. Pull all the wires off your cells and remove the entire table cable assembly from the machine. You will be going into the front wireway so be sure to disconnect the main power to the machine. Inside the front wireway you will see a small terminal board that the table cable goes to. Disconnect only the table cable terminals. Now you will be left with only the wires going from the terminal board to the chassis. Remove one of the wires from the numbered terminals and attach it to the ground terminal on the board. If you choose to remove your GP switch, then make sure both yellow wires are connected to the same terminal on the board. Hope this helps and doesn't confuse.

Re: eliminating table wires

Before you do this, what kind of scoring do you have? Do you have "smart" chassis, (mp's, omega tech expanders, XOP's?) If you don't this will not work, it will leave you with a mess and reinstalling the wires. Otherwise, Pete is right on the mark about how to remove the wiring. I would also remove the GPS as it is really not needed.

Re: eliminating table wires

If you have VanTech scoring, you can remove your table cable and continue to use 5-board chassis or single-board conversion without expander. A set of contacts on the curtain wall simulates the RS circuit.
Accuscore doesn't do this, and Magic Triangle pindication will not work with any setup other than wires on each respot cell.
Hope this helps!

We're running amf accuscore with solid state chassis upgraded with omega tek mk-70 boards. Will this work for us?

Re: eliminating table wires

how would you do this if you had 82-70 with the qubica scoring and ss chasis with the omega-tech board

<font size="2" face="Verdana, Helvetica, sans-serif">We have Accuscore +, and Omega-Tek Boards. You will need the expander board if you don't have it already. All my machines have the plug
Disconnected from the machine. Only 4 of my machines have the wire's and GP switch's removed from the table, I am removing them as I rebuild the tables. Best thing we have ever done.

<font size="2" face="Verdana, Helvetica, sans-serif">That's our setup exactly... you can remove the wiring... it's not needed for the scoring (and actually causes problems by overriding the short strike if a wire is grounded out)

See the post above for removal instructions.

<font size="2" face="Verdana, Helvetica, sans-serif">Hmm. OK.
I just ass-u-med based on 1) My experience with putting a very old Creative 1-board where 5 boards had been and finding no pin lights lit, and 2) Coors' Carzy pictures here , here and here .
Because clearly , Coors is a man of good taste.
If he's got Qubica, he's got no use for table cables, except to light the triangles!
It takes a proud individual to go to all that trouble to light the triangles even when it's no longer necessary except for pride!
Or am I mistaken?

Re: eliminating table wires

So basically this expander board converts a SS chassis already equiped with a mk-70 board to a MP chassis with a scoring interface? I'm not much of a chassis person, but how does the chassis communicate with the scoring? I just thought the two were independent of each other. Is there more wiring involved to make the two parts communicate?

Re: eliminating table wires

Chad:
You can have pindication with expanders without table wiring.

Casey:
There is a wire that you must add that goes from the Scoring Plug to the Expander Board in the chassis. The scoring system tells the chassis which pins are standing (and the chassis lights them up if you have pindication masks).

Re: eliminating table wires

I should have been more specific... I figured that if you had Qubica scoring, you were already using the expanders for machine control. If you're running without expanders, the wiring needs to stay in place. You can simplify it a bit, but you will also eliminate pindication. You can run a single wire that links all the cells together on the table, then run just one wire up to the #1 pin connector in the wireway, instead of 13 wires going to the wireway. Has it's good and bad points... it eliminates the table cable, but if you get a grounded cell, it makes it a bit of a trick to find if it's not something obvious like a broken wire or a connector grounding out.

The board you need to interface with the scoring is an MK70EX... it goes into the chassis alongside the existing MK70 board, and has a wire harness that connects to the long connector on the back of the MK70 board (if your boards don't have this connector, you can send them back to Omega-Tek, and they'll upgrade them). At the top of the EX board, there is a 4-pin connector that interfaces with the scoring system. Being that you have Qubica scoring, the unit that connects the MK70EX board to the scoring system is called an XLMP. It's a little black box with an indicator and a terminal strip. You need one for each pair of lanes.

One correction... the MK70EX will NOT light the pinlamps off the scorer output. It has a set of indicators that show HOW MANY pins are standing (the 1-2-4-8 lights on the EX board), but it only holds the #1 pin or #5 pin circuit to control machine cycles. To continue using pindication, you have to keep the table cable on the machine and in good repair... and the pin mask will always show a 1 or 5 pin standing. The 1-ball, 2-ball, Strike, and Foul lights will continue to work normally.

It's better for the chassis if you remove the 1-10 pinbulbs anyway... the MK70 board runs a lot cooler when it doesn't have to drive all the mask lamps.

Re: eliminating table wires

hey g-man i am not sure i know if i have the expander boards since i dont know exactly what these are i have a omega tech board and it has the wireing going to another smaller board would the smaller board be my expander board? also we nolonger use the pindicators since we have the qubica system.

Re: eliminating table wires

some time ago about a year now i finished my auto sweep reverse for the off spot on the 82/70's
i spoke about my next mod, it was to interface with the accuscore to do every thing that the omega expander board does but with out one, as the prices here in australia, also to have a system that worked with any type of chassis for the 70's on the market, 5 boards and all. just like the sweep reverse, now at the stage of having a fancy led setup that shows me all the remaining pins feed straight off the CWC, and the interface with the m/c to adj cycle position etc. now just have to marry them together....
