1.
Designate the Master controller by setting its OFAF ID to “1”. Generally, this is the
controller on the far end of the network from the LN2 supply.
2. Connect one end of the OFAF Master Cable to either Serial Port 1 or 2 of the Master
controller.
NOTE: Either Serial Port 1 or 2 can be used for OFAF as long as the COM
Types are in agreement.
3. Connect an RJ-45 splitter to the next controller in the network. Connect the free end
of the OFAF Master Cable to this splitter.
4. Set the OFAF ID of this second controller to
“2”.
5. Connect an RJ-45 splitter to the third controller in the network. Connect the splitters
on the second and third controllers with a standard CAT 5e cable.
6. Set the OFAF ID of the third controller to
“3”.
7. Continue this pattern until all controllers in the network are daisy chained and
assigned sequential OFAF IDs.
8. Each controller in the network should also have the following settings:
a. Auto Fill Control
“Enabled”
b.
COM Setup “9600 N81”
c. COM Type
“OFAF”
d.
OFAF Type “Sequential” or “Simultaneous”. All controllers in a network must
have the same OFAF Type.
e.
OFAF Units “# of controllers - 1”. The Master controller is not counted in the
number of OFAF Units. All controllers in a network must have the same
number of OFAF Units.
