This pin is connected to ground.
This pin is the input to the DM2200-916VM on-board voltage regulator. The minimum input voltage to this pin is
3.3 V, and the maximum input to this pin is 14.0 V.
This pin is the enable input for the DM2200-916VM on-board regulator. To enable the on-board regulator, con-
nect this pin to J1-2. To disable the on-board regulator, connect this pin to ground.
This pin is connected to the DM2200-916VM positive power supply buss. When the module is powered from
the on-board regulator, this pin can provide up to 5 mA of current at 3.0 Vdc. Note this current adds to the re-
ceive, transmit and sleep currents listed in the specifications on Page 1. The external load must not impress
more than 10 mV peak -peak ripple on the supply buss. If the on-board regulator is disabled, the module can be
powered through this pin by an external 2.9 to 3.7 Vdc source (maximum ripple 10 mV peak-peak).
This pin is only used for factory programming. It must be left unconnected in normal operation.

This pin is an auxiliary digital I/O pin. The default configuration of this pin is a digital output.
This pin is an auxiliary digital I/O pin. The default configuration of this pin is a digital output.
This pin is an auxiliary digital I/O pin. The default configuration of this pin is a digital output.
This pin is a software reset pin. Logic high is normal operation. Logic low invokes software resets.
This pin is connected to ground.

This pin is the serial data input (CMOS).
This pin is the serial data output (CMOS).
This pin is a serial data flow control input (CMOS).
This pin is a serial data flow control output (CMOS).
This pin is an I/O pin dedicated to monitoring the RSSI circuit output. It is configured as an analog-to-digital
converter input. The RSSI signal can also be monitored externally at this pin.
This pin is an I/O pin. The default configuration of this pin is a digital input with optional pulse counting capabil-
ity. A 24-bit register is maintained within the DM2200 to accumulate pulse counts. This input can count up to
10 pulses/second. This input supports interrupts, allowing pulse counting or alarm monitoring while the DM2200
is operating in a low current “sleep” mode.
