* 1. Digital input signals are 0 when open, and 1 when closed (running a jumper to short the signal
and common terminals).
Additionally, Selection switch S1 sets the input signal for 12 or 16 bit.
* 2. In BCD input, the most significant digit can be set from 0 to 15 (0 to 10 for VS-676VG3/VH3
series Inverters), while the other digits can be set from 0 to 9.
* 3. When TB1-10 is set to 0, the input signal is read as the digital reference. To accept the digital
reference signal, a jumper should be place to short TB1-10 and TB1-11 as shown in Fig. 4.
For applications that perform a continuous read, a jumper must be placed between TB1-10
and TB1-11.
