3. The descriptions of the signal contents
| • | BCD output Pin No.1 to 20 |
| Positive/negative logic change 5-digit parallel output Open collector output | |
| The bit switch 3 shown in the following figure <8> can change the logics, ON is for negative logic and OFF is for positive logic. |
| • | Polarity output Pin No. 25 (+ output), Pin No. 26 (- output) Open collector output | ||||||||||||
| ○ | When bit switch 3 is set to ON to select the negative polarity; | ||||||||||||
|
|||||||||||||
| ○ | When Bit switch 3 is set to OFF to select the positive logic, above Pin No. 25 and No. 26 polarity outputs ON/OFF are all reversed. | ||||||||||||
| • | Decimal point output | ||||||||||||
| Pin No. 27 (D.P 3, when selected the minimum measurement unit as 10 µm) | |||||||||||||
| Pin No. 28 (D.P 4, when selected the minimum measurement unit as 1 µm) | |||||||||||||
| Open collector output | |||||||||||||
| ○ | When Bit Switch 3 is set to ON to select the negative logic. | ||||||||||||
|
|||||||||||||
| ○ | When Bit switch 3 is OFF setting to select the positive logic, above Pin No. 27 and No. 28 polarity outputs ON/OFF are all reversed. |
||||||||||||
| • | Error output Pin No. 30 |
||||||||||||
| Open collector output | |||||||||||||
| When miscounting occurs in the counting circuit of the counter, the ON signal is output which is continued until reset. | |||||||||||||
| • | HOLD input Pin No. 31 | ||||||||||||
| When a low level voltage signal is input, the displayed value and BCD output data are held and the print command signal is output. While the low level signal is input, the HOLD state is continued. However, counting is still operated in the counting circuit according to the input signal from the gauge sensor while the HOLD state is retained. Therefore, when the HOLD state is released, the displayed value and BCD output data are changed to a value measured at that time. | |||||||||||||
| • | RESET input Pin No. 32 | ||||||||||||
| When a low level voltage signal is input, the displayed value BCD output, error indication, and error output are reset. While the low level signal is input, the RESET state is continued. | |||||||||||||
| • | BUSY input Pin No. 33 | ||||||||||||
| Same as HOLD input. Using for the timing when the external devices (printer or more) are in use. | |||||||||||||
| • | Print command output Pin No. 35 | ||||||||||||
| Open
collector output When the HOLD or BUSY signal is input to hold the displayed value and BCD output, the negative pulse print command signal is output. |
