PRODUCT FEATURES & BENEFITS
The TCP/IP-220 is a network adaptor that can be fitted to any CRC220 or CRC221 door controller module to provide TCP/IP data communications between the door controller and the PC hosting the Norpass3 network management software. The interface can support the connection of a further 31 door controllers via an RS485 bus so that they can be served by the same TCP/IP port, thereby enabling flexible use of the available cabling infrastructure.
The fitting of a TCP/IP-220 adaptor is quick and simple and can be fitted to any of the door controllers on the system according to the availability of existing or planned data communications installations.

Leverage Existing Network Infrastructure for Access Control Communication
The TCP/IP-220 transforms how access control systems connect to management software, enabling CRC220 and CRC221 controllers to communicate over standard Ethernet networks instead of dedicated RS485 cabling.
For buildings with extensive IT infrastructure, this eliminates the need to run new communication cables—simply connect to the nearest network point and configure the IP address.Multi-building campuses and retrofit installations particularly benefit from the TCP/IP-220.
Universities can connect access controllers across campus via existing LAN infrastructure, while historic buildings avoid disruptive cable routing.
The adaptor's RS485 port allows up to 31 additional controllers to share the same Ethernet connection, creating hybrid networks that optimise cabling costs while maintaining system reliability.

Network Ready
Connect access controllers to Ethernet using existing IT infrastructure.
Hybrid Networking
Combine TCP/IP with RS485 to optimise cabling across large installations.
Easy Retrofit
Quick daughter-board installation to upgrade existing CRC220/CRC221 controllers.
Simple Config
Device software streamlines IP address assignment and network setup.
The TCP/IP-220 fits any CRC220 or CRC221 door controller PCB as a daughter board, effectively replacing the standard RS485 communications interface with TCP/IP capability.
One TCP/IP-220 can serve as the network gateway for up to 32 controllers total—the adaptor itself plus up to 31 additional controllers connected via RS485 daisy-chain.
No, the adaptor draws its 5V DC power directly from the host CRC220/CRC221 controller board. Typical current consumption is 230mA.
The adaptor uses standard Ethernet (RJ45) connection. The included device installation software simplifies IP address assignment and network parameters configuration.
Yes, this is a key benefit. TCP/IP-220 adaptors can be strategically placed at network access points, with RS485 serving controllers in areas without Ethernet drops.
