Wireless Telemetry Figure 2 Multi camera configuration point to multi point telemetry Telemetry For telemetry systems that would usually require a dedicated cabled link to each camera e g as used with RS232 type telemetry or co axial telemetry with twisted pair adapters VITX5800SED and VRX5800SED units may be used to duplicate this in wireless form providing dedicated video and telemetry radio links to each camera This type of system requires a different Rf channel to be selected for each telemetry link For telemetry systems that have addressable cameras operating on an RS485 multi drop e g daisy chained twisted pair the VideoWave units may be configured as illustrated in figure 2 above A three camera system requires a VITX5800SED combined video transmitter and radio modem unit at each camera It will require three video receivers but only one radio modem that can broadcast the telemetry signal to all three cameras This can be achieved using one combined video and data unit VRX5800SED and two video only units VRX5800SE Please refer to the separate RDT data sheet for details of the VRX5800SE VideoWave units if required When used in this configuration all radio modems in the system should be set to the same channel This system configuration offers a cost effective solution to wireless telemetry transmission as only one radio modem is used at the base location VideoWave General Video Input Video Output Operat
