When integrating Suprema devices into Genetec Security Center, special care must be taken regarding Input configuration Due to the way the Suprema Plugin and SDK handle input mapping, misconfiguration can result in unexpected behavior or inoperative inputs, particularly in offline scenarios.
⚙️ 1. Input Configuration Limitation
In Suprema architecture, input types (e.g., REX, Door Contact) can only be configured after the device is mapped to a Door.
? Root Cause:
Suprema SDK requires inputs to be assigned at the Door level, not at the device level.
Therefore, there is no way to pre-configure input types before assigning the device to a Door in Genetec.
⚠️ Any input type changes made via:
Config Tool → Access Control → Cloud Link → Peripherals Tab will not apply to the Suprema device directly.
✅ Plugin’s Auto Assignment Logic:
| Input Number | Input Type Assigned by Plugin |
|---|---|
| Odd Numbers | NO (Normally Open) |
| Even Numbers | NC (Normally Closed) |
This automatic assignment helps ensure compatibility when mapping inputs post-Door configuration.
⚠️ 2. REX Behavior in Online and Offline Modes
Suprema devices only accept one REX input, and for it to work reliably in both online and offline modes, it must be:
Assigned to the same side as the Reader (usually the "IN" side)
? Root Cause:
In Genetec, devices are most commonly assigned to the same side of a Door.
If REX is mapped to the OUT side, and no device is assigned to that side, the Plugin cannot sync the input to the device.
This results in the REX not being recognized by the device, especially in offline mode.
✅ Working Case
REX input is configured on the same side as the Reader
→ Works in both online and offline modes
❌ Not Working Case
REX input is configured on the opposite side where no reader/device is attached
→ Works only in online mode (offline mode fails)
? Best Practices Summary
| Configuration Target | Recommended Setup |
|---|---|
| REX | Use an odd-numbered input and assign it to the same side as the reader (typically IN side) |
| Door Contact | Use an even-numbered input |
| Offline REX Operation | Ensure REX is mapped to the side where the Suprema device is physically assigned |
