The SABRE
™
RANGER 5000 terminal incorporates an embedded serial device server (Serial to
IP). With the Serial to IP capability, the data collected from the RS232 serial device can be
retrieved locally through the local LAN or remotely through the Internet.
A serial device server can transfer the data between a computer serial (COM) port and an Ethernet
LAN port.
It is recommended for connecting your RS232 serial device to an IP-based Ethernet LAN. The
serial device server can support up to 4 simultaneous connections, which allows multiple clients to
collect data from the same serial device concurrently.
Navigate to
Menu > Settings > Terminal Settings> I/O Configurations
to enable the serial
device server.

TCP/IP Settings
1. Time Configuration
TCP alive check time
is the inactivity timeout (min) used to disconnect an idle TCP connection.
By default, it is configured as 10 minutes.
0 minute
:
TCP connection will not be disconnected due to an idle TCP connection.
1 to 99 minutes:
Based on the TCP alive check time, the terminal will deactivate the TCP
connection if no TCP activity within the configured period. After the
connection is closed, the terminal will be standby
for another host’s TCP
connection.
TCP keep alive time
is the time to keep the connection active in between the terminal and the
remote PC. By default, it is configured as 0 minute.
If the user sets the keep alive time as 1 minute, the terminal will send an empty packet every 1
minute to ensure that the connection of the remote PC is still active.
Inactivity time
is the reference idle time for a TCP connection to deactivate due to an idle serial
data connection. By default, it is set as 0 minute.
0 minute
:
TCP connection will not be
impacted
by an idle serial data connection.
1 to 99 minutes:
Based on the inactivity time, the terminal will deactivate the TCP connection
if no serial data activity within the configured period. After the connection is
closed, the terminal will be
standby for another host’s TCP connection.
