Configuration
Mode:
Serial mode to be used with give daughter board, possible options are RS-232 and RS-485.
Baud Rate:
The baud rate setting, possible options are 1200, 2400, 4800, 9600, 19200, 38400, 57600,
115200. Default is 1200.
Data Bits:
This option configures the number of data bits in each serial frame, possible options are 5, 6,
7, 8, and 9. The default is 8.
The second or lower daughter board is limited to a data bit range of 7, 8, and 9.
Parity:
This option configures the type of parity check bits in each serial frame, possible options are
None, Even and Odd. The default is None.
Stop Bits:
This option configures the number of stop bits in each serial frame, possible options are 1 and
2. The default is 1.
Flow Control:
This option configures the flow control mode, possible options are None and Hardware. The
Hardware option uses RTS and CTS has hardware flow control lines. The default is None.
Protocol:
This is the protocol used by the iRIS via the given serial daughter board. The options are:
§
HyQuest – used with iLink, HydroTel and SODA.
§
Modbus RTU – this is binary format of Modbus (used over serial connections)
§
Modbus TCP – or Modbus TCP over Serial, to be used with Serial to Ethernet converters.
Leading Characters:
This option configures the number leading 0xFF characters applied to the beginning of each
HyQuest protocol packet. This can be used to provide a delay after initial transmission before
valid packet data is transmitted.
Trailing Characters:
This option configures the number trailing 0xFF characters applied to the end of each HyQuest
protocol packet. This can be used to provide a delay after transmission valid packet data to
ensure the radio channel is kept open and not truncating the end of the packet.
