bbConfigureIO

Configure the two I/O ports on a device
bbStatus bbConfigureIO(int device, unsigned int port1, unsigned int port2);
Parameters
device
port1
port2
Description
NOTE: This function can only be called when the device is idle (not operating in any mode). To ensure
the device is idle, call
bbAbort().
There are two configurable BNC connector ports available on the device. Both ports functionality are
changed with this function. For both ports, '0' is the default and can be supplied through this function to
return the ports to their default values. Specifying a '0' on port 1 returns the device to an internal time
base and outputs the time base AC coupled. Specifying '0' on port 2 emits a DC coupled logic low.
For external 10 MHz timebases, best phase noise is achieved by using a low jitter 3.3V CMOS input.

Handle to the device being configured.
The first BNC port may be used to input or output a 10 MHz time base
(AC or DC coupled), or to generate a general purpose logic high/low
output. Please refer to the example below. All possible values for this
port are found in the header file and are prefixed with "BB_PORT1"
Port 2 is capable of accepting an external trigger or generating a logic
output. Port 2 is always DC coupled. All possible values for this port are
found in the header file and are prefixed with "BB_PORT2."
For port 1 only a coupled value must be 'OR'ed
.
