WARNING: take care not to exceed the voltage limits to the VCC, TTL SERIAL, and PIO pins.
0 negative voltage or voltage e xceeding 3.30VDC can permanently damage the device.
OPERATING MODES
0-Slave Mode - The default mode, other devices can discover and connect to the RN-24.
1 - Master Mode (SM,1<CR>) Enables outbound connections. To connect, use the “C” command.
2-Trigger Mode (SM,2<CR>) Automatically connects to stored address, when data is received on
local serial port of master.
3-Auto Master Mode (SM,3<CR>) Automatically connects to stored address on power up.
4-DTR Auto Master Mode (SM,4<CR>) Automatically connects/disconnects using PIO6 pin.
NOTE: In all master modes the device will not be discoverable or remote configurable.

modes.
The RN-24 can communicate via serial port using either TTL (0-3.3V DC) or RS-232 Levels.
Factory default enables the on-board RS232 chip. To Disable RS-232 and use TTL pins,
remove resistor R7 located on the bottom side of the module, near the tab of the power regulator.
PIO Pins
These settings can be overridden by commands and the PIO pins can be used as general purpose
Input and output pins.
