DIP Switches 5 and 6 control the clock parity
| DIP | Polarity | Value | Comment |
| 5 | Clock | 1 = standard for SYNC applications | The Clock polarity switch determines whether the falling or rising edge appears on the SYNC clock output when a MIDI clock is received. Normally this setting is of no account as the clock pulse width (i.e. the time difference between the falling and rising edge) is very small (about 4 milliseconds in the 1:1 setting). If you have the impression that there is a small time difference between your device and MIDI clock you may change the setting of the clock polarity. |
| 6 | Start/Stop | 1 = standard for SYNC applications | The Start/Stop polarity switch is used only for special applications (e.g. for drum computers with inverse Start/Stop control: 0V=Start, +5V=Stop) |
