Step Procedure
Step 3c Set the Heart Beat Time to a value from 1
to 65534 seconds. Default is 45 seconds.
Note: Use a value of 0 to disable the heartbeat
timer.
Step 3d Set the Baud Rate.
Step 3e Set the Parity.
Step 3f Set the Data Bits.
Step 3g Set the Stop Bits.
Step Procedure
Step 3h Set the Flow Control.
Step 3i Click on the desired Auto TCP Mode
selector.
Your choices are:
DSR – Initiate the TCP connection
when the SDS serial port's DSR
becomes active
Data – Initiate the TCP connection
when the SDS serial port receives data
Step 3j Set the Auto TCP timeout interval if you
selected Data as the Auto TCP Mode.
Note: This selection is only available if the
Auto TCP Mode selector is set to Data.
Otherwise, it is grayed out.
Step 3k Set the IP Address of the TCP host to
which the SDS will connect.
Step 3l Set the TCP Port number of the TCP host
to which the SDS will connect.
Step 4a Configure the serial port interface.

Steps 4a through 4d apply only to RS-232/422/485 (MEI) units

Configuring the SDS using a Web interface
Description
performance for most applications.
Low Latency mode heavily favors
responsiveness over throughput.
Heartbeat messages help detect when a
connection has been lost between the PC
driver and the SDS.
If you need quick notification that the
connection has been lost, set this timer to
a shorter value.
If you are more concerned about network
traffic, set this timer to a longer value.
The SDS and the serial device(s) to
which it is attached must use the same
serial connection speed.
Parity can be odd, even, or none.
Data Bits can be 7 or 8.
Stop Bits can be 1 or 2.
Description
Flow control determines the handshake
method used between the SDS and the
serial device(s) to stop the serial
input/output process
This selection determines whether the
SDS port will initiate a communications
link when DSR becomes active or when
data is received at the serial port.
Typically, the DTR output of the device
to which you are connecting drives the
DSR input on the SDS serial port.
Sets the number of seconds before the
TCP connection is dropped after data
stops.
This selection sets the IP address to be
used in Auto TCP mode.
This selection sets the TCP port for Auto
TCP modes.
This series of steps only applies to MEI
