7.2.6 Data

Bits

7

or 8

This parameter sets the number of data bits for each word used by the protocol.
All devices communicating through this port must use the same number of data
bits.

7.2.7 Stop

Bits

1 or 2

Stop bits signal the end of a character in the data stream. For most applications,
use one stop bit. For slower devices that require more time to re-synchronize,
use two stop bits.

All devices communicating through this port must use the same number of stop
bits.

7.2.8 RTS

On

0 to 65535 milliseconds

This parameter sets the number of milliseconds to delay after Ready To Send
(RTS) is asserted before data will be transmitted.

7.2.9 RTS

Off

0 to 65535 milliseconds

This parameter sets the number of milliseconds to delay after the last byte of
data is sent before the RTS modem signal will be set low.

7.2.10 Minimum Response Delay

0

TO

65535

This parameter is used only when the port is configured as a slave. It sets the
number of milliseconds to wait before responding to a command received on the
port from a remote Master. This delay is sometimes required to accommodate
slower Master devices.
