CAUTION • Connect all signal lines using a twisted-pair cable. Connect the return side to the signal ground level. • Make sure the signals satisfy electrical characteristics. • Set the leading edge and trailing edge times to 0.5ms or less.
• Do not ignore Ack or BUSY signals during a data transfer. Ignoring such signals may result in data corruption. • Make the interface cables as short as possible. NFC Tag Transmission standard ISO14443 A Frequency 13.56 MHz Memory 144 byte Transmission distance Approximately 10 mm from the NFC installation location. When UB-R04 is installed, you cannot use the printer's built-in NFC. Install the NFC tag for the UB-R04 at a location that is remote from the printer's built-in NFC. • The transmission distance is an estimate that depends on our experiment conditions and is not a guaranteed value. • It varies based on the installation environment and target device.
