Signal Connections
The EQ-99-FC is controlled through the remote I/O connector.
Table 3 gives the pin assignments and functions for this interface. Connect to the user’s

Optionally, connect a model EQ-99-RC remote control module to the I/O connector using
the supplied cable
User I/O can be powered either by the EQ-99 internal isolated power supply, or an external
