18.2.1.7.

Modbus Baud Rate

Default is 9600 baud. Available communication speeds are



9600



19200



28800



38400

Note: Care must be taken to make sure the selected speed matches that of the
master or there will be communication problems.

18.2.1.8.

Modbus Parity

Default is Even. Available choices include Even, Odd and None.

Note: Care must be taken to make sure the selected parity matches that of the
master or there will be communication problems.

18.2.1.9.

Modbus Delay before Tx

Default is 100ms. This identifies the number of milliseconds to wait before
starting data transmission. This is useful if the device is connected to a radio
requires keying initialization before data transmission. The possible delay ranges
are 10ms – 2000ms.

18.2.1.10.

Modbus Delay after Tx

Default is 10ms. This identifies the number of milliseconds to wait after data
transmission. This is useful if the device is connected to a radio that requires a
hold-off time after data transmission has completed. The possible delay ranges
are 10ms – 2000ms.

18.3.
