For details on the use of the Galil extended I/O board, IOM-1964, please chick here.

Currently only output bit 33 is expected to be used:

Bit 33: Network/Hardware error. This signal is used to control the Net/Hardware Error LED on the front panel.

ADC Cell inputs:

Bit 49: Forward cell retract secondary limit. This signal goes high when in a limit
Bit 50: Forward cell deploy secondary limit. This signal goes high when in a limit
Bit 51: Aft cell retract secondary limit. This signal goes high when in a limit
Bit 52: Aft cell deploy secondary limit. This signal goes high when in a limit
Bit 53: Aft cell home fiducial. This signal goes high when homed

Cable connection sense inputs:

Bit 57: Motor connected. This signals goes high when the motor cable is disconnected
Bit 58: Motor encoder connected. This signals goes high when the motor encoder cable is disconnected
Bit 59: Load encoder connected. This signals goes high when the load encoder cable is disconnected
Bit 60: Forward cell limit cable connected. This signals goes high when the forward cell limit cable is disconnected
Bit 61: Aft cell limit cable connected. This signals goes high when the aft cell limit cable is disconnected
Bit 62: Manual paddle connected. This signals goes low when the Manual Paddle is connected
Bit 63: Main signal cable connected. This signals goes low when the main signal cable at the ADC cell interconnect panel is connected

Other inputs:

Bit 65: E-Stop input. This signals goes high when the observatory E-Stop is active.
Bit 66: Emergency Stop input. This signals goes high when the emergency stop button has been pushed.
Bit 67: Local/Remote switch input. This signals goes low when the switch is in the 'Remote' position.
Bit 68: Bypass mode switch. This signal goes low when the bypass mode is selected.

This page just shows that there are no connections made to the Hi-current outputs. It is here just for completeness.
