Re v 1 .5 0 (3 /1 3/2 00 5 ) Page 63
Step Procedure Description
# Step 1 Select the serial port you want to
configure.
Click on a port number to select that
port. The selections on the screen are
automatically populated with any
existing parameters for the selected port.
# Step 2
Click on the Auto TCP Operating Mode
selector.
Auto TCP allows an SDS device to act as
a client and to connect to the server when
DSR is active or when data is received.
You will find directions for configuring
ports in Normal, Tunneling, and Raw
TCP modes in the preceding sections.
Directions for Raw UDP mode are in the
following section.
# Step 3a
Configure the Operating mode.
Click on the desired data Rate Multiplier.
Your choices are:
! Auto (Recommended)
! Force X2 mode
! Force X4 mode
! Force X8 mode
The auto setting has no effect on the
baud rate you set. However, if you select
X2, X4, or X8, the baud rate of the serial
port will be the baud rate that you set
multiplied by 2, 4, or 8, respectively.
Note: Forcing a change in the data rate may
cause communication problems with some
serial devices. If this is the case, change the
setting back to Auto (Recommended).
# Step 3b Click on the desired Performance
Selector.
Choose balanced mode except in those
cases where the serial device cannot
tolerate the slight delays inherent in
normal TCP/IP operation.
Balanced mode offers excellent
performance for most applications.
Low Latency mode heavily favors
responsiveness over throughput.
# 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.
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.
# Step 3d Set the Baud Rate. The SDS and the serial device(s) to
which it is attached must use the same
serial connection speed.
# Step 3e Set the Parity. Parity can be odd, even, or none.
# Step 3f Set the Data Bits. Data Bits can be 7 or 8.
# Step 3g Set the Stop Bits. Stop Bits can be 1 or 2.
