Viper will not transmit until valid RX and TXfrequencies have been entered and this radio button has been deselected.There are 32 channels available. The radio button beside each channel will select that channel as the active channel. Eachchannel can operate in simplex (one frequency) or half duplex (pair of frequencies) mode. The transmit power output levelcan be set for each channel. The channel type can be selected for each channel. All Viper in the network must be set to thesame bandwidth.Refer to Appendix A – Specifications for available bandwidths and data rates by model. It is the installer’s responsibility tocheck the FCC license to determine the correct parameters and settings for channel frequencies, power level, and channeltype.4.3.4 SERIAL PORTSViper has two serial ports (SETUP/COM). Each port must be activated independently. Either port can be configured to senddata over the air, connect to the CLI (command line interface), report online diagnostics, or be custom configured tosend/receive data on a specific port to/from a specific IP address.Check the Enabled box at the top to activate.
