RF Cables and Accessories Description RFCAB5M2 5.0m RG-213 type Antenna Feeder Cable terminated with N type Male Connectors Antenna Yagi 6 Element 9dBd Alum 850930MHz RFCAB10M 10.
O Series Data Radio – User Manual Part C – Applications Generic Connectivity Application Detail The O Series has been designed for SCADA and telemetry applications, and any other applications that use an ASCII communications protocol, and which connect physically using the RS-232 or RS-485 interface standard. SCADA Systems Any protocol that can be displayed using a PC based terminal program operating via a serial communications port is suitable for transmission by the O Series radio modems.

O Series Data Radio – User Manual Other Pins 13 Analogue RSSI O Synthesised average of RSSI (20dB/V absolute reference : -90dBm = 1.25v) [can also be used as a general purpose analogue output] 0-2.5v 24 PTT I Keys the radio at maximum TX/RX duty cycle using the current programmed channel selection and output power (Active Low).
O Series Data Radio – User Manual Part E – System Planning and Design Obstructed Radio Path Understanding RF Path Requirements This path has an obstruction that will seriously degrade the signal arriving at the field site. A radio modem needs a minimum amount of received RF signal to operate reliably and provide adequate data throughput.
O Series Data Radio – User Manual Effect of Earth Curvature on Long Paths This path requires greater mast height to offset the earth curvature experienced at such a distance (73km). Selecting Antennas Antennas There are basically two types of antennas – omni-directional and directional. Omnidirectional antennas are designed to radiate signal in a 360 degrees segment around the antenna.
O Series Data Radio – User Manual Antenna Placement RF Feeders and Protection When mounting the antenna, it is necessary to consider the following criteria: The antenna is connected to the radio modem by way of an RF feeder. In choosing the feeder type, one must compromise between the loss caused by the feeder, and the cost, flexibility, and bulk of lower loss feeders.
