6.5 Connect to LAN
TFIR-31LAN series image reader has a RJ-45 connector. Please use a UTP cable of
category 3 or greater. The reader is equipped with automatic negotiation function for
both transfer speed (10Mbps) and communication mode (Full Duplex, Half Duplex).
Ensure to set the host PC’s LAN settings (transfer speed and communication mode)
to automatic if the reader is connected to the PC through a cross-over cable
(peer-to-peer communication).
6.6 Manage communication status
The TFIR-31LAN series image reader supports the TCP/IP and the UDP/IP (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.)
(Command)
→
discon 27110
(Responce) → disconnected
[UDP/IP connection]
The reader also works as an UDP/IP server whose port number is always 49460.
Multiple units can be connected to a host by UDP/IP protocol.
By using a broadcast address, it is possible to send packets to all units in the
local network at the sametime. Broadcast address can make the followings
