Unit ID Number
The Unit ID Number is used strictly for communication purposes; it can take any value from 1 to 247.
Note: Do not duplicate the Unit ID number in a single communication loop!
This situation will lead to response collisions and inhibit communications
to units with duplicate ID numbers.
Only one master can exist in each loop.
Flow Computer Ports
Port #1 (RS-485) Modbus Type
Note: this parameter must be set the same for both the PC and the SFC332L
Flow Computer for communication to occur.
The Modbus Communication Specification is either Binary RTU or ASCII.
Port #1 (RS-485) Parity
Note: this parameter must be set the same for both the PC and the SFC332L
Flow Computer for communication to occur.
RTU - NONE
ASCII - EVEN or ODD
Set the parity to match the
Modbus Type
.
Port #1 (RS-485) Baud Rate
Note: this parameter must be set the same for both the PC and the SFC332L
Flow Computer for communication to occur.
Baud rate is defined as number of bits per second. The available selections are 1200, 2400, 4800, 9600, or
19200.
Port #1(RS-485) RTS Delay
This function allows modem delay time before transmission. The SFC332L Flow Computer will turn the
RTS line high before transmission for the entered time delay period.
Port #2 (RS-232) Baud Rate
Baud rate is defined as number of bits per second. The available selections are 1200, 2400, 4800, 9600, or
19200.
Port #2 (RS-232) Modbus Type
Note: this parameter must be set the same for both the PC and the SFC332L
Flow Computer for communication to occur.
The Modbus Communication Specification is either Binary RTU or ASCII.
Port #2 (RS-232) Parity
RTU - NONE
ASCII - EVEN or ODD
Set the parity to match the
Modbus Type
.
