5.1.2.5
Operation Mode – UDP
If both the Remote Host Computer and the serial device are expected to initiate a data transfer, the operation mode for the
"Virtual COM" function on the router must be set to "UDP". In this mode, the UDP data can be transferred between the
router and multiple host computers from either peer, making this mode ideal for message display applications.
The remote host computer can directly send UDP data to the serial device via the gateway, and also receive UDP data from
the serial device via the router at the same time. The router supports up to 4 legal hosts to connect simultaneously to the
serial device via the router.
UDP (User Datagram Protocol) enables applications using UDP socket programs to communicate with the serial ports on the
serial server. The UDP mode provides connectionless communications, which enable you to multicast data from the serial
device to multiple host computers, and vice versa, making this mode ideal for message display applications.
