FOX3 T 201 Transmitter • Installation and Operation 15
RS-232 Insertion
A user can connect a control system to send and receive RS-232 data over the fiber and
the captive screw port of the transmitter and receiver.
Captive Screw Insertion
A user can connect an RS-232 signal from a control system to an endpoint and pass that
signal over the fiber to the connected endpoint. An RS-232 signal must be inserted in the
RS-232 port on the transmitter or receiver and bidirectional fiber must be used.
The RS-232 signal settings are:
• Baud rate: 9600 (default) to 115200 • Stop bits: 1 (default) to 2
• Data bits: 5 to 8 (default) • Parity: Odd, Even, or None (default)
The RS-232 insertion method must be set to Captive Screw Insertion via PCS (see the
FOX3 SR 201 Help File) on both endpoints passing the control signal.
Example of a bidirectional fiber system (see figure11):
• On the FOX3 transmitter and receiver, configure the RS-232 Insertion via PCS.
• The control system then sends a control command:
• Into the transmitter Control RS-232 port.
• Out of the transmitter SFP A port to the receiver SFP A IN port.
• To the receiver captive screw port.
• Into the display to take some action.
• The response from the display is sent back to the control system.
