CONNECTION SCENARIO 2 – USING A KBD4000 FOR MULTIPLEXER CONTROL
Refer to Figure 46 and the instructions that follow.
NOTE: If you set all your cameras to Standard Coaxitron for better control on the browser, you will lose most of the KBD4000 keyboard
control functions. If you set your cameras to Extended Coaxitron, you will have all the keyboard functions but the PTZ functions on the
NET4001A will be very slow.

1.
Connect a PV130 converter to the COM1 port on the back of the NET4001A receiver unit. (For Interface Mode select RS232.) The
data format must be 9600 baud, 8 data bits, odd parity, and 1 stop bit.
