1. Connect a DB9 cable to the RS232/422/485 port on the NET300 receiver. (In the Interface Mode field on the configuration page for the
interface settings, select RS-422/485.) The data format should be 9600 baud, 8 data bits, odd parity, and 1 stop bit.
NOTE: If you set all your cameras to Standard Coaxitron for better control on the browser, you will lose most of the KBD4000 keyboard
functions. If you set your cameras to Extended Coaxitron, you will have all the keyboard functions but the PTZ functions on the NET300 will
be very slow.
