Figure 2-2 RRL Station
A 900 MHz radio module is used in RRL Stations. RRL Stations come standard with six (6) 3.6V AA replaceable
lithium batteries and antenna. There is input for two dataloggers, with the option of using Splitters to allow
the connection of up to four dataloggers. There is a connection for an external power supply; the RS232
connection on each RRL Station is used for diagnostic, firmware updates and programming purposes.
Dataloggers, Direct Read Cables, Wellhead Cables and Reader Cables to be used with the System are purchased
separately. External power cables, RS232 cable, higher gain antenna and Splitters are optional extras. External
power sources (such as solar panels) are user supplied, as are other installation housings and requirements.
RRL Stations are designed to fit into 4.5" (115 mm) diameter wells for discrete placement. The case is rugged
and waterproof with an IP66 rating and has an operating temperature range between -20 to +50 degrees
Celsius.
RRL Stations have a non-volatile internal memory of 128 KB (13,000 sets of LT readings or 10,000 sets
of LTC readings). A Remote Station stores collected data in its memory until the Home Station has been
successfully contacted. The light on the RRL Station flashes with every transmission activity.
