Power requirements
The RIM 801D OEM Radio Modem must be provided with a clean, high
current power source. This can be provided by a plug-in power supply unit,
a rechargeable battery pack, or single use batteries. RIM has conducted
extensive research and has developed guidelines for integrators to follow
when designing the power supply system for the RIM 801D OEM Radio
Modem.
Care should be taken when supplying power to the RIM 801D. Connecting
with the wrong polarity will damage the radio. We recommend protecting
the radio from reverse polarity by attaching a Schottky diode in series with
the Radio Modem’s power cable if there is any danger of reverse
connection. A 1N5822 is suitable for this purpose.
Load specifications
The RIM 801D OEM Radio Modem draws its power in bursts; the power
required can change rapidly as it begins or ends a transmission. The load
profile is given on the following page. These specifications should be used
when choosing the battery or power supply system for your application.
They can be given directly to your power supply designer or battery
supplier. Please note that these specifications are subject to change without
notice.
