2 Pin configuration of P44 radio is shown in table 2.1 below
PIN No. Signal Name
1 GND Reference node for all receive transmit and power
signals. Proper grounding requires metal screws in the
four corners mounted to a common chassis.
2SW_B+ Transmit - Max 2A @ 7.5VDC @ 5 Watt
Receive - 47mA @ 7.5VDC
3 XMIT_B+ This signal is Asserted only during transmit time . 250
mA @ 7.5VDC
4 RX_5V Not Connected
5 TX_5V Asserted during Transmit - 40Ma @ 5VDC
6 MODE_IN Analog data in to the radio to be transmitted.
DC coupled with a nominal bias of 2.5VDC.
7 SQ_DET Output signal from the radio indicating that there is a
valid RF signal on the channel
8 Reset This pin in pulled up in the radio. In normal mode must
kept up. Used when programming the radio.
9 RSSI Output signal from the radio. The Volt level of this pin is
according to the RF level of the received signal.
10 Audio_Out Received analog data is transferred to the CPU via this
pin.
11 CH_SEL_B Channel select pin (1 out of 7)
12 CH_SEL_A Channel select pin (1 out of 7)
13 CH_SEL_C Channel select pin (1 out of 7)
14 CH_SEL_D Channel select pin (1 out of 7)

3.2 Channel Change
The radio can operate in multi channel mode and single channel mode and is
programmable via the RSS software of Mobat.
3.2.1 Single Channel
In this mode only channels 1, and 2 are operational.
CH_SEL_A is 0VDC Channel 1 is selected
CH_SEL_A is 5VDC Channel 2 is selected
When this signal is changed an interrupt is generated on the radio and the channel is changed.
