8.5. RS-232 Pin Assignments (DB-9)
RS232 Pin Assignments (DB-9)
Pin Assignment Signal Description
1 CD - Carrier Detect Output Used to show an RF connection between radios.
2 TX - Transmit Data Output Used to transmit data bits serially from the radios to
the system device.
3 RX - Receive Data Input Used to receive data bits serially from the system
device connected to the radios.
4 DTR - Data Terminal
Ready
Input Used only in radios in Point-to-Point Slave/Master
switchable mode or for DTR Connect.
5 GND - Ground Signal return for all signal lines shared with Pin 9.
6 DSR - Data Set Ready Output Always high when the radio is powered from the 2.5
mm power connector. Indicates power is on to the
radio. Also, this pin can be used for +12.0 Volts when
powering the radios directly through the RS232 port.
Important!: This is not used on the OEM
module.
7 RTS - Request to Send Input The radio does not recognize RTS for flow control.
RTS is used as a control line in RTS/CTS mode.
8 CTS - Clear to Send Output This signal is used to tell the system device connected
to the radio that the radio is ready to receive data.
l When asserted, the radio accepts data, when de-
asserted the radio does not accept data.
l This should always be used for data rates above
38.4KB or a risk of lost data may occur if an RF
link is not very robust.
9 GND - Ground Signal return for all signal lines shared with Pin 5.
