3.13 RS485 Parity Selection
This screen allows setting of the parity and number of stop bits of the RS485 Modbus/JC II port.
Where the transducer unit is separate from the display unit, the transducer has two Modbus
ports, one of which may be used for communicating with a display. The RS485 Parity Selection
option only sets the parity for a port that is not communicating with a display unit. The port
characteristics for communication with a display are preset.
If the JC NII protocol is to be used, this parameter must be set to No parity and One stop bit.
Press >> to accept the currently displayed value. The next Set-
up screen will then appear.
To change the parity press .
Use the key to scroll through the available values:
odd – odd parity with one stop bit
E – even parity with one stop bit
no 1 – no parity one stop bit,
no 2 – no parity two stop bits.
Select the required setting and press >> to confirm your
selection. The Confirmation screen will appear.
Press >> to accept the new setting. The next Set-up screen will
appear.
