functions are not needed.
Note:
If you do not want to convert the binary numbers to hexadecimals
yourself, look up the values in
Table 6-7. Pack Control Options
in the Binary

Idle Time:
Idle time to "Force transmit" defines how long the unit should wait before
sending accumulated characters. This wait period is between characters. If there is
an idle period between characters equal to the force transmit set, then the SDS will
package up the serial data currently in the buffer and send it to the network.
Trailing Characters:
In some applications, CRC, Checksum, or other trailing
characters follow the end-of-sequence character; this option helps to adapt frame
transmission to the frame boundary.
Send Characters
: If 2-Byte Send Character Sequence is enabled, the unit interprets
the sendchars as a 2-byte sequence; if not set, they are interpreted independently.
If Send Immediately After Send Characters is not set, any characters already in the
serial buffer are included in the transmission after a "transmit" condition is found. If
set, the unit sends immediately after recognizing the transmit condition (sendchar or
timeout).
Note:
A transmission might occur if status information needs to be
exchanged or an acknowledgment needs to be sent.
DisConnTime (Inactivity Timeout)
Use this parameter to set an inactivity timeout. The connection is dropped if there is
no activity on the serial line before the set time expires. Enter time in the following
format:
mm:ss
, where
m
is the number of minutes and
s
is the number of seconds.
To disable the inactivity timeout, enter
00:00
.
Send Characters
You can enter up to two characters in hexadecimal representation in the parameters
"sendchar." If a character received on the serial line matches one of these
