Raveon Technologies Corp.
7)
Broad RF Options.
Radio modems used within the TechSeries enclosure are
available from Raveon in VHF, 220MHz, UHF, 800MHz, 900MHz, and 3G
cellular bands.
8)
Wide DC input.
Most Tech Series modems will work off of any DC input
voltage from 10V to 30V DC, twice the range of most radios.
9)
Multiple Protocols.
Tech series radios support many different protocols, such
as 4800, 9600, 19200 baud data modems, Bell 202 legacy analog AFSK
modulation, POCSAG paging, and audio modulation. 3G cellular and LoRa
WAN are also available.
2.5. Power
The TechSeries products from Raveon utilize a 3-pin power connector. Coincidentally,
the industry name for this connector is “
M8
”. The three pins are:
1.
VIN.
DC input voltage. Refer to the specific model number data sheet for input
voltage range.
2.
GND.
Chassis ground and sometimes cable shield.
3.
GND
. Chassis and signal ground.
4.
Enable
. Input to enable/disable the product. Connect to ground to turn off the
radio. It has an internal pull-up resistor on it. It must be > 2V for the product to start
working.
2.6. Power Cable
The cable that connects to the M21 and all Tech Series products is typically wires as
shown here. This 2 meter cable is Raveon part number 4C850-1.
Pin 1 (VIN)
is a brown wire. Connect to + DC input voltage.
Pin 3 (Ground)
is a blue wire. Connect to Ground or negative input voltage.
