Dear All, Could you please take a look on my explanation to help me? Our system has 2 things:
Two devices are connected via TCP/IP protocol with following setup: Reader: IP address: 172.21.16.3; Port 10001 Subnet Mask: 255.255.255.0 Default gate: 127.21.16.254 PC: IP address: 172.21.16.4 Subnet Mask: 255.255.255.0 Default gate: 127.21.16.254
The first connection: RFID reader and PC are connected directly. On PC, we used Hyper Terminal to collect data from RFID reader with the setup in attached file.
The result: PC and RFID can communicate, PC received data from RFID reader. We used scan port soft to check IP and port. Both of them were informed to be alive. The second connection: RFID reader and PC are connected via network (the system has 1000PC). On PC, we used Hyper Terminal to collect data from RFID reader with the above setup: The result: PC and RFID can not communicate with warming “unable connect” We used scan port soft to check IP and port. Port 10001 was informed to be closed. Questions:
