Digital inputs
- The jumper is located inside the unit on the base plate slightly below the centre and to the right of the 4 relays
- If digital inputs are used as S0/NPN then VikMote must be supplied with 24 VDC or 230 VAC
| Digital inputs | Terminal | Use | Note |
| Input 1 | DI1 |
If jumper JPDI1 is in position N, the signal on DI1 must be 8-40 VDC (PNP) If jumper JPDI1 is in position S, the signal must be between GND and DI1 (S0/NPN) |
Use PNP or NPN signal |
| Input 2 | DI2 |
If jumper JPDI2 is in position N, the signal on DI2 must be 8-40 VDC (PNP) If jumper JPDI2 is in position S, the signal must be between GND and DI2 (S0/NPN) |
|
| Input 3 | DI3 |
If jumper JPDI3 is in position N, the signal on DI3 must be 8-40 VDC (PNP) If jumper JPDI3 is in position S, the signal must be between GND and DI3 (S0/NPN) |
|
| Input 4 | DI4 |
If jumper JPDI4 is in position N, the signal on DI4 must be 8-40 VDC (PNP) If jumper JPDI4 is in position S, the signal must be between GND and DI4 (S0/NPN) |
|
| Input 5 | DI5 | The signal on DI5 must be 8-40 VDC (PNP) | Use only PNP signal |
| Ground | GND | Ground for inputs 1..5 | Must always be connected |

Analogue inputs
- The jumper is located inside the unit on the base plate slightly below the centre and to the right of the 4 relays
| Analogue inputs | Terminal | Use | Note |
| Input 1 | AI1 |
If jumper JPAI1 is not installed, a 0-10 V signal is used on AI1 If jumper JPAI1 is installed, a 4-20 mA signal is used on AI1 |
Connect the transmitter between AINx and AGND using 0-10 V or 4-20 mA |
| Input 2 | AI2 |
If jumper JPAI2 is not installed, a 0-10 V signal is used on AI2 If jumper JPAI2 is installed, a 4-20 mA signal is used on AI2 |
|
| Ground | AGND | Ground for analogue inputs | Must always be connected to the transmitter reference point (ground) |
