IP / LAN Settings

If you have the WF2IR then please read here for specific setup info.

Global Caché network-connected products currently support network connectivity through Ethernet or WiFi, depending on product line and model. By default, all devices are configured to automatically acquire their IP configuration via DHCP. However, if a DHCP server is not available, devices will assume a default static IP address as specified in each device’s documentation. Configuration of a device’s network and I/O settings can be managed through the product’s configuration web pages, or via API commands if supported by the product Global Caché Unified TCP API (see here).

For detailed information about configuration and operation of the various products from a user perspective, please refer to each product’s Quick Start or User Guide here.

Connect both an RJ45 (Ethernet) network cable and power supply to your iTach unit. If the iTach is PoE (Power over Ethernet) enabled, connecting a power supply is not necessary.

In its default configuration, the iTach TCP/IP models use DHCP to automatically obtain an IP address from your router. To determine the iTach’s IP address, download the iHelp application here.

Run iHelp on a Windows PC connected to your network. iHelp listens for Global Caché multicast beacons and displays the iTach IP address and other details within one minute. If a DHCP server is not present, defaulted iTach units will reside at IP


iTach configuration can be reset to factory defaults by inserting a large metal paper clip into the small opening located to the right of the power connector. Only insert the paper clip approximately 1/8” (3mm) in. The LEDs on the front of the iTach will rapidly blink in unison, indicating a reset. Use a light touch when resetting your iTach, as force may damage your iTach hardware irreparably.

Network Port Usage

Discovery Service9131 (UDP)The beacon is a UDP packet sent to the multicast IP address on UDP port
number 9131. Any system listening to this address and port will receive the periodic beacon message.
The message is sent 3 seconds after power on and then at random intervals of 10 to 60 seconds

Network Capacity: Notes on Simultaneous TCP Connections
The iTach Series of devices supports 8 simultaneous open TCP software connections.

Doorlock Sensor Crestron Home Driver Datasheet

Driver Functionality:

The 2N Driver Series allows sophisticated control of the 2N Intercom systems. Along with standard intercom functionality between the intercom panel and the gate/door control there is now the ability to lock/unlock, detect states of lock/unlock and set AutoLock functionality.

In addition to control from the Tile and UI this driver has Sequencing actions that can be used via a quick action that can be selected from the actions button when a SIP Call is received from the front gate station.

Door Lock Function:

We control Lock/Unlock state of the door lock.


We control either Switch 1 or Switch 2 in the 2N Relay. This is configurable in the admin setup along with the IP address of the 2N device.

The Driver calls on the 2N rest API to activate the Switch on the unit.

On the unit the Switch must be configured to control the desired output device.

Door Sense Function

Door sense functionality updates the status of the tile feedback when the door is opened without the lock being released by an action from the driver. It will also indicate if the door is opened when the lock is enabled. See Feedback states above.
