Page 8 of the attached PSR for G0001777 explains the Hopper Options. It sounds like you are looking at the Operator Menu, not the Key Chip Menu.
Pressing the reset button on the MPU enters Operator Mode.
To get to the Key Chip Menu, power off, replace the M0000526 chip with Key 17, power on, wait a few seconds for the purple screen and two lit LEDs. Power off, replace the Key 17 with the original Base M0000526 and power on again and wait for the initialization to complete. You should then be in Key Chip Mode. From there, you can change your Cashout Device settings. Also, check the Denomination settings, hopper/coin acceptor denomination (page 6).
