The CB127 adapter cable bridges the gap between 5-pin and 4-pin connector systems, letting you connect a 5-pin device to a 4-pin Verity system (or vice versa) without needing to replace or rewire your existing hardware. Unlike the CB125, this version has no jumper wire, for use where a direct pin-to-pin connection is required.
This compact 30cm cable is a practical solution for installers working with mixed Verity hardware generations or configurations, simplifying integration without complicated rewiring.
