RF Board Level Pinout
The RF Board Level transceivers are available in both TTL and RS232 versions.
The TTL versions use reverse polarity from standard RS-232 at 0 to 5 Volt levels. All pin descriptions and
pin numbering are the same as the RS232 version. The RS232 versions use standard RS232 polarity and
voltage levels for all of the RS232 signal lines (DTR, Transmit Data, Receive Data, Carrier Detect, RTS,
and Clear to Send) and TTL standard polarity and voltage level for the Interrupt pin.
pin numbering are the same as the RS232 version. The RS232 versions use standard RS232 polarity and
voltage levels for all of the RS232 signal lines (DTR, Transmit Data, Receive Data, Carrier Detect, RTS,

Pin 1: B+ Power input.
Pin 2: Interrupt (INT) – Input – A 0 volt level on this pin will switch the radio into Setup mode.
