When all OE-2’s connected to the system are addressed, the next step is to poll the GPIB bus to
see that each
OE-2 is correctly addressed. This is done with the Optical Channel Assignment
dialog box. Clicking on the
Optical Channel Assignment tab will initiate the polling process.
Each correctly addressed OE-2 will be shown in the Optical Input window along with its GPIB
device address.
If a connected
OE-2 does not appear in the dialog box, its address may be incorrectly set.
Return to the
GPIB Address Assignments window to correct the address settings.
Dual-channel
OE-2’s will occupy two lines in the Optical Input window - one for each optical-
to-electrical channel path in the
OE-2. The left-hand OE-2 channel will be named “Port 1” and
the right-hand channel will be named “Port 2.”
Optical Configuration Dialog Box - Optical Channel Assignments
Finally, it is necessary to assign each OE-2 channel to a channel of the
WAVECREST
DTS or
SIA instrument by highlighting one line in the Optical Input field (corresponding to one channel
path) and selecting the DTS or
SIA input channel in the SIA Channel field. To activate this
channel, click the “Active” box.
For example, if you have an optical signal connected to the left hand input port of the
OE-2, and
the electrical output of this same channel connected to the channel 3 input on a
WAVECREST
SIA-3000, the Optical Channel Assignment should read:
OE-2, GPIB Device 6, Port 1 3 Active
Channel Ports left in the inactive state will still pass signals, but VISI software will not recognize
the channel port.
