6.1 Power Sources and Antennas

Power Supply

Note:

The RRL Gold Home Station and any Relay Station requires an external power supply.

RRL Stations come standard with six (6) 3.6V AA lithium batteries. The batteries must be installed for proper operation, even if you use an additional external power source. The life of the battery varies depending on the frequency of your Sample and Report Rates. The following are estimates based on the standard lithium batteries, with the Radio Power setting at 1 Watt. With the Radio Power set at 100 mW, the battery life increases by about 10% of the estimates below. RRL Gold Stations can also be powered by six (6) user-supplied 1.5V AA alkaline batteries. With alkaline batteries, the battery life will be about 40% of the estimates below.

Note:

Where possible, use lower Radio Power settings and/or longer Report intervals to conserve Remote Station Battery life.

Note:

The internal RRL Gold batteries are not rechargeable.

Note:

Rechargeable batteries can not be used inside any RRL Units (Home, Relay, Remote), as the voltage would be to low.

RRL Gold Home Stations and Relay Stations require an external power supply. Remote Stations may also require an external power supply, depending on your Sample and Report Rates and site needs. Solinst supplies a cable for connecting to an AC power source and a cable to connect to a user-supplied 12V battery or solar panel. Cables are connected to the RRL Gold Station beside the antenna connection (see Figure 6-2).

Note:

STS/RRL Gold Software Version 1.3.0 is compatible only with the latest RRL Gold Firmware 1.003. See Section 5.2 for firmware upgrade instructions.

The six (6) 3.6V AA batteries must be installed for proper operation, even if using an additional external power source.

  1. External AC (mains) power. Simply use the Solinst supplied adaptor cable (pt#109720 - North American) shown in Figure 6-3 to connect the RRL to an AC power source. The adaptor has input from 90 - 246VAC. See connection diagram in Figure 6-4.
