Connect to LAN
Use a dedicated LP-ABR series LAN cable to connect. Auto-negotiation function

cable. Therefore, configure the LAN setting (communication speed and
communucation mode) of your computer to auto-setting at a one-to-one

Manage Commnunication Status
The LP-ABR series supports 4 types of communication method:
-
TCP server communication (for all commands)
-
TCP client communication (for reading result transmission)
-
TCP client communication (for image data transmission)
-
UDP communicatoin (for administration)
[TCP/IP connection]
The reader works as a TCP/IP server whose port number can be set to any value.
Only one client can be connected at a time.
The reader will disconnect in the following situations:
-
Receive close request from the client
-
Detect transmission error
In the following cases, the reader cannot detect disconnect state:
-
A UTP cable was removed before the client sent close request.
-
The client aborted the system without sending close request.
To recover the connection, send the command
“discon” through RS232C
interface for forced termination, and then retry the connection.
e.g.)
