Ok, this would be much easier if you could tell me the actual error but let's start troubleshooting. We can start with the hardware, the POG machine has to believe it has a printer so there is a cable mod they do where a modded cable is placed in ports 1 & 3 of the PC board. Do you have that cable in place ? Now on to the software, go into settings mode and select "Main Config" make sure "Maximum Cashout" "Maximum Ticket" "Maximum Credit" are all at $99,999. Make sure "Special Win" and "Minimum Cashout" are set at $0. Now exit "Main Config" and enter "Terminal Config" and follow these settings : "Coin In" at CC40/30, "Bill In" at No Bill, "Printer" at CTZN614. All other settings except Game Config should be at default. You can factory reset the board before doing these adjustments to be sure.
