Description
1 = enable port, 0 = disable port
1 = Modbus Slave Port
0 = Modbus RTU mode, 1 = Modbus ASCII mode
Sets the baud rate for the port. Valid values for this field are 110, 150,
300, 600, 1200, 2400, 4800, 9600, 19200, 384 or 3840 (for 38,400
baud), 576 or 5760 (for 57,600 baud) and 115,1152, or 11520 (for
115,200 baud)
0 = None, 1 = Odd, 2 = Even
8 = Modbus RTU mode, 8 or 7 = Modbus ASCII mode
Valid values are 1 or 2
0 to 65535 milliseconds to delay after RTS line is asserted on the port
before data message transmission begins. This delay can be used to
allow for radio keying or modem dialing before data transmission
begins.
0 to 65535 milliseconds to delay after data message is complete
before RTS line is dropped on the port.
N or Y
O ES
This parameter is used to enable or disable hardware handshaking.
The default setting is N hardware handshaking, CTS Line not used.
O
Set to N if the connected devices do not need hardware
O
handshaking. Set to Y if the device(s) connected to the port require
ES
hardware handshaking (most modern devices do not). If you set this
parameter to Y , be sure to pay attention to the pinout and wiring
ES
requirements to ensure that the hardware handshaking signal lines
are properly connected; otherwise communication will fail.
As a Slave, emulates Enron/Daniel style floats. See Floating Point
Data Handling for more information (page 84).
Register offset in message for floating data point. See Floating Point
Data Handling for more information (page 84).
