PRL-1600 Wireless Pulse Link
The PRL-1600 is SSI’s 4th Generation wireless pulse link and is a point-to-point system with one transmitter and one receiver for short-hop pulse applications like parking lots, fields, roads, railroad tracks or anywhere where it is difficult to get a KYZ pulse from the meter. Using Frequency Hopping Spread Spectrum (FHSS) technology allows excellent reliability and rejection of any other noise sources. There are 6 selectable channels. Each channel incorporates 50 of the 64 assigned frequencies within the 900 MHz band. The same channel is selected on both the transmitter and receiver. Other PRL-1600 systems within the same radio airspace (~2-4 mile radius) will need to be assigned a different channel number. The Transmitter and Receiver are “paired” such that the Receiver will only accept meter pulse data from its specified Transmitter.
The PRL-1600 can transmit either 2 Form C (3-wire) pulses or 4 Form A (2-Wire) pulses. Transmissions are sent once every 10 seconds with the number of pulses which have been received by the transmitter in the last 10 seconds. The receiver then re-creates the pulses over the next 10 seconds. In this way, pulses are always delayed by 10 seconds, and additional error-checking and transmission acknowledgement are used for high accuracy.
The PRL-1600 Wireless Pulse Link system consists of one PRT-1600 Transmitter and one PRR-1600 Receiver. The system operates in the 900MHz band and is FCC pre-certified, thus allowing unlicensed operation by the user. The PRL-1600 will transmit pulses up to 5,000 to feet in a line-of-sight (LOS) configuration. Distances vary with the terrain, obstacles and greater elevation above the ground.
PRT-1600 PULSE RADIO TRANSMITTER UNIT
The PRR-1600 can be configured as 2 Form C or 4 Form A output channels and acts as the system’s Receiver. The PRR-1600 consists of a PRR-16 Receiver Base Unit where all connections are made and a PRNR-1600 Receiver Radio/Antenna unit which contains the radio transceiver and antenna. The PRNR-1600 is intended to be mounted outdoors, in direct line-of-sight with the PRNT-1600 transmitter radio/antenna unit and should not be obstructed by trees, buildings or other objects. Each time a packet is received from the PRT-1600, the Receiver validates this packet and outputs it’s respective pulses on the PRR-16 Base unit. channel. An encoded FHSS communication scheme is used to ensure the accurate number of pulses are sent and received. The PRR-1600 consumes extremely low power and can be operated using 120V or 277V AC line power or a +12VDC voltage source. The pulse rate is up to 4pps (Form C).
*Both the Transmitter and Receiver units are capable of operating on supply voltages of 120, 208-277VAC, as well as +125VDC, +12VDC, and +15 to +48VDC by employing the special SSI DCS power supply options.
