bits-per-second (bps) and must be set to one of the following speeds:
1200, 2400, 4800, 9600, or 19200.
The second parameter of the
block indicating how the data is encoded:
= Data bits (7 or 8)
a
= Parity (N for None, O for Odd, E for Even)
b
= Stop bits (1 or 2)
c
The factory default setting is 9600 baud, 8 data bits, no parity, 1 stop bit
(Example: ).
9600 8N1
NOTE: 7N1, 8O2, and 8E2 are invalid communication settings and are
not supported by the transceiver.

(stores) the data until enough bytes have arrived to cover worst-case
gaps in transmission. This mode of operation is required for protocols
such as MODBUS™ that do not allow gaps in their data transmission.

transmitter's baud rate is greater than or equal to the receiver's baud
rate. Enforcement of this rule is left to the user.
In some rare cases, the default timing parameters for Seamless Mode are
not optimal. In these cases, the user might need to specify an exact delay
time. To set a custom delay time, enter
