NCR 7169 - User Datagram Protocol (UDP) Socket Communication

Communication 4-125
User Datagram Protocol (UDP) socket communication
The User Datagram Protocol (UDP)socket is used through sending and receiving of a
real time command. The communication is effective in UDPport 3000 and when the
Ethernet RTCProtocol setting is UDP. The communication procedure is as follows:
1. Client PCconnects to the UDPsocket through the defined port number of the
printer.
2. Client PCsends the status command and receives the status from the printer
throughUDPsocket.
Multiple connection
It is possible to connect with multiple clients at the same time. However, if the
transmission in the first connection is incomplete, the next connection cannot transmit
data to the printer during its session.
The maximum possible number of connections is six. More than seven connections will
be rejected.
