CAUTION
Pins 10, 12, 18 and 21 of the controller's connector are specifically used for TPB connection. To avoid possible
accidents do not connect other inputs to these pins.
When using optional POPCOM software, make connections while referring to the POPCOM operation manual
since it shows the different connection specifications.
The personal computer may have its own connector specifications, so be sure to check the computer operation
manual to ensure the connections are correct.
