Overview V3R-FX IC444:

V3R-FX IC444 was developed to enable direct interfacing between the Optocore open transmission and Intercom platforms allowing for a flexible audio based intercom transport solution and GPIOs. It is now possible to take advantage of all Optocore system features and benefits when transport four-wire and GPIO signals. Based on the well known V3R-FX series architecture, with 1U height, the device is equipped with D-SUB 37pin interfaces, making cabling simple and cost-efficient. 

Optocore's intercom device is seamlessly integrated into the OPTOCORE® OPTICAL DIGITAL NETWORK SYSTEM. Each single intercom channel can be routed to every device in the network by the OPTOCORE CONTROL software.
