7.3 Serial connector configuration
The setting selected here becomes active whenever the RU is switched on. If the setting has been changed
by pressing the function button as described in chapter 5.6, this setting becomes active again when the
function button is pressed for less than a second. The configuration options are the following:
Radio unit with RS-232 interface with handshaking
Can be selected from a predefined list of:
–
MCU UARTs (Data and NMS) to SATBUS (normal setting when RU is permanently
operating with the CU).
–
Data UART to Radio D9 RD/TD (standard RS-232 interface, normal setting when
the RU is operating in transparent mode of data transfer).
–
Data UART to Radio D9 RD/TD – NMS to DTR/DSR (RS-232 data transfer using
handshaking, need to simultaneous monitoring using NMS).
–
Data UART to Radio D9 RD/TD – NMS to RTS/CTS (RS-232 data transfer without
handshaking, an alternative to the previous setting).
–
Data UART to Radio D9 RD/TD – NMS to SATBUS (standard RS-232 interface,
need to use the CU as a configuration tool).
–
MCU UARTs (Data and NMS) to SATBUS with CAN.
Radio unit with RS-422/-485/-232 interface without handshaking
Can be selected from a predefined list of:
–
RS-422
–
RS-485
–
RS-232 (RD, TD & SGND only)
In the latter model it is not possible to have simultaneous data and NMS. However, the serial connector
can be configured to accept offline NMS messages as explained in chapter 5.6.
