Controlling the UDMR from external devices (control input terminals)
55
Designating phrase numbers using binary numbers (binary
playback)
Definition of binary playback
The binary playback operation enables phrase selection via
binary signal input to terminal nos. 1-9, and playback of
selected phrases via control signal input to the '10 START'
terminal. You can select and play back up to 500 phrases
(using two memory cards).
Binary playback can therefore be used to designate all
phrases using control signals (on/off for switches etc.) without
the need for personal computers or other complex devices.
To use the binary playback function, a control device capable
of generating a separate binary signal is required.
Please ensure that the input of binary signal designation is
completed within 50msec.
Terminals used for binary playback
1-8:
used for binary designation of phrases using a
combination of 0 (off)/ 1 (on) signals.
9:
used to select memory cards A or B using 0 (off)/
1 (on) signals.
10START (start): used to start phrase playback.
STP (stop):
used to terminate the phrase playback.
The STP terminal is turned 'ON' by creating a short circuit with
the above terminals and the COM (common) terminals.
Binary playback can still be performed even when all nine of
the control input terminals are not connected. The number of
phrases which can be designated is determined by
subtracting 1 from the nth power of 2, wherein n is the
number of connected terminals.
For example, when using a timer etc. with three outputs, the
equation becomes 2 to the 3rd power minus 1, which means
that seven phrases (001-007) can be designated.
Furthermore, where no connection is made to terminal no. 9
(card selection), this terminal is deemed to be 'OFF', and
memory card selection is limited to card A.
However, a separate connection is required for the start
signal (terminal no. 10).
