Reference Guide
This chapter lays the groundwork for the communication protocol between client software running on a remote
computer and the V750 reader.
2.1 System Interface
2.1.1 Command I/F function
Via 10/100BaseT Ethernet or RS-232C, the host issues a command to control the R/W. As the control method,
V750 employs original procedures. Same commands are used for Ethernet and or RS-232C.
(1) Ethernet
Ethernet is connected with the host such as server computer with TCP/IP protocol.
IP address corresponds to variable IP address assigned by DHCP server. You can choose between static IP
(Default 192.168.1.200) and variable IP. Default setting is static IP. 使用する Port 番号は 7090。I P アドレスと
Port 番号は、設定コマンドまたは Web画面から変更可能。If the reader can’t detect DHCP server under
various IP address setting, it will indicate error occurrence and start up with changing various IP address
setting into the static IP. Under Safe Mode, IP address shall be always set static IP (192.168.1.200).
(2) RS-232C
The reader conforms to the RS-232C standard. It can connect with the host such as PLC. You can choose
following communication conditions.
