Software User’s Manual800 & 500 Series Reader Demo (.NET) 36Appendix4 Troubleshooting1 Serial Port Connection FailureCheck whether the COM port of the reader is connected with the corresponding port. The serial link baud rate of computer and reader must be identical with that of reader. Whether the serial port cable is correctly connected. Disconnection or loose connection may disable the instructions from the computer to the Reader;2 Network Port Connection FailureThe default IP address is 192.168.0.210. The connection between the Reader and PC can be established if the PC’s IP address and Reader’s IP address are in the same network, segment (e.g. 192.168.0.XXX), or of connected networks, The Reader IP can be set by using Demo software in a computer with RS-232 serial port if the IP address is missing.3 USB Port Connection FailureCheck whether the PC has identied such USB Device. If identication is failed, please install USB driver by referring to Section 3.2.Check whether the USB cable is correctly connected, as disconnection or loose connection may disable the instructions from the computer to the Reader.4 Unable to Read TagsCheck the serial port cable, USB cable or network cable is correctly connected. Disconnection or loose connection may disable the instructions from the computer to the Reader. Check whether the antenna’s SMA connector is tight, and whether the tag is damaged. Whether the Antenna number on the main interface is correctly selected and whether it is identical with port number of external antenna. Whether the ‘Number of Tags to be Read’ is correctly set. (It shall be approximate to the number of the tags within the antenna’s coverage)
Software User’s Manual800 & 500 Series Reader Demo (.NET) 37Appendix5 How to operate readers remotely? Reader is equivalent to a network terminal. Demo software can be connected with IP address port (For connecting XCRF-800 Series reader see IP connection of 3.2; for IP address settings, see 3.4 in reader parameter settings; for connecting XCRF-500 Series reader, see IP Settings of 4.2; IP address settings, see 4.4 IP settings; reader port number is xed at 7086); the reader can be operated when connection is established .6 Must IP address range be reserved for reader?Every reader needs an IP. IP address of reader can be set, ensuring that there is not |IP address conict between reader and other network devices. Reader does not automatically check the IP conict. 7 How to cancel configuration parameters operation, such as: access password, kill password, and EAS? For setting access password and kill password, see 4.3.9 and 4.3.10. Access password and kill password will be valid when Locking tag (4.3.11) is completed. For EAS conguration settings see 4.3.13, 4.3.14 and 6.1.14. Only one tag will set off alarm when EAS function. In other words, EAS is designed to set off on the alarm of the EAS tag with EAS.8 How to set the EPC matching?EPC matching is valid for the 12-byte EPC number. EPC matching instructions include three parameters; one to set or cancel the parameter, one to match EPC parameter, and one to match mask parameter. Matching is based on bit match. Matching a mask of which one bit is 1 will be effective. Matching a mask of which one bit is 0 will not be effective. For example, to read the EPC of which the rst 2 bytes is “1234”, set the parameters to match the EPC code as “12340000000000000000” (16 hex), and set the matching mask parameter as “ffff00000000000000000000” (16 hex). This conguration enables the acquisition of tags of “1234 ********************”. For additional information, contact your Invengo representative.
