Setting Description
Serial port function Terminal Use the pull-down menu to select a controllable device from the pull-down menu: Terminal, Transparent, or Pelco
Prot (protocol).
If the port must transmit data transparently, select Transparent. You can use Pelco Prot to send any kind of con-
trol data for a Spectra, Esprit, Genex, or a Pelco matrix.
Baud rate 19200 Use the pull-down menu to select a transmission rate from 600 to 115200 baud. Refer to Appendix A for settings.
Data bits 8 The number of data bits is set at 8 per character.
Stop bits 1 Use the pull-down menu to select the number of stop bits (1 or 2) per character. Refer to Appendix A for settings.
Parity check None Use the pull-down menu to select the type of parity check (None, Even, or Odd). Refer to Appendix A for settings.
Interface mode RS232 Use the pull-down menu to select the required protocol for the port (RS232 or RS422/485). Use RS-232 for two-wire
communication (TXD and RXD) and RS-422 for four-wire communication (TX+, TX-, RX+, RX-). (RS-485 is not normally
used except in advanced applications.)
Half-duplex mode Off This mode allows NET350 to receive data only and not transmit data. If you choose this RS-232 mode, by selecting
On, camera control data is transferred automatically to COM 1, which is a serial interface on the unit’s rear panel to
which you can connect a PC. This mode supports data flow control. (Refer to Table A.)
Buffered mode also transfers data input to COM 1.
Depending on the equipment used, the Serial Port Function field may have to be set to Transparent if sending any
control data.
Genex protocol ID N/A Enter the address of the Genex unit with which you want to communicate.
Spectra/Esprit
protocol ID
N/A Enter the address of the Spectra or Esprit unit with which you want to communicate. This must match the P-protocol
address of the Spectra or Esprit unit.
