Table shows pin number (remote number)
Note:
Remote 1 and Remote 3 are 26-way high-density D-Type female sockets. Frame
ground is pin 2 and +5V @500mA is pin 1 in each case.
Remote 2 and Remote 4 are 26-way high-density D-Type male plugs and frame
ground is pin 6 in each case and +5V @500mA is pin 15 on Remote 2.
Note: The +5V output is protected by self-resetting thermal fuses, which limit the
total output current available from Remotes 1-4 to approximately 1A.
