 A signal name with a rule above it indicates an "L" active signal.
 Bidirectional communications cannot take place, unless all signal names for both sides
correspond to each other.
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.

Transmission distance
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.
