    CAB 4n CobraNet Hardware Manual Audio input and output modules The CAB 4n supports a number of different input and output modules. These modules are factory fitted into the four-channel bays at the rear of the unit. Note: A CAB 4n may be ordered short loaded, that is, with some of the bays empty. In this case, blanking panels will be fitted.

    Chapter 3 - Introduction to CAB 4n Using a CAB 4n with a NION The CAB 4n is designed to work in conjunction with a NION. In the example below, a project is created in NWare, then deployed to a NION, so it can control the CAB 4ns on the network.

  • Page 18: Introduction

    CobraNet audio systems. In MediaMatrix, the minimum CobraNet network consists of a single NION, a CAB 4n audio bridge loaded with appropriate MM™ I/O 4 ch cards and a single Ethernet switch. Many systems will include more NIONs and CAB devices, but this is the most basic configuration.

  • Page 19: Connections

    CAB 4n CobraNet Hardware Manual Connections CobraNet network connection The first priority is the CobraNet™ network connection. The RJ-45 connectors on the CobraNet interface are designed to connect with standard, off-the-shelf Category 5, 5e or 6 cable for use with standard Ethernet network switches.

  • Page 20: Audio Connections

    Chapter 4 - Installing the CAB 4n Configuration 2 Instead of using a switch, you can connect the CAB CobraNet port directly to the CobraNet port on your NION. However, this type of direct connection requires a crossover cable. For more information, we recommend that you search the internet.
  • Page 21 CAB 4n CobraNet Hardware Manual If you want to connect an unbalanced audio source to the CAB or NION, make the connections as shown in the table below. Unbalanced input cable CAB or NION input connector Positive (+) Positive (+)
  • Page 22 Chapter 4 - Installing the CAB 4n Pin outs The RS-485 connector has two sets of terminations that are wired in parallel. This allows you to bus adjacent serial data connections at each network location. With this type of connection, there is no input or output.
  • Page 23 CAB 4n CobraNet Hardware Manual All cable types must be properly installed and terminated to meet specifications. The cable must not be kinked or bent too tightly (the bend radius should be at least four times the outer diameter of the cable). The wire pairs must not be untwisted and the outer jacket must not be stripped back more than 1/2 inch (1.27 cm).
  • Page 24 Chapter 4 - Installing the CAB 4n Link connections The CAB 4n features built-in Buddy Link functionality for creating backup I/O configurations in mission critical systems. Each CAB 4n features rear panel, dual BNC connectors labeled LINK IN and LINK OUT. These connectors enable you to connect adjacent CAB units for redundancy.

  • Page 25: Setting The Hardware Id

    CAB 4n CobraNet Hardware Manual For input audio, the secondary CAB 4n is prevented from transmitting onto the CobraNet network by the action of the Buddy Link. The fact that audio is present, but is muted by relays for output, and by the CobraNet transmission being turned off by the Buddy Link, means the quick response of the redundant CAB is greatly enhanced.

    Appendix A - Reference Information GPIO overview NION and CAB products include a versatile GPIO (General Purpose Input Output) system at the rear for terminating external logic, controls, relays and other external systems. Each control pin is supported by NWare for configuration, control and monitoring. Any combination of control pins may be used simultaneously, regardless of the configuration.
  • Page 29 CAB 4n CobraNet Hardware Manual Connection A 25-pin DSub connector (DB-25) is used for accessing the GPIO functions. Although you can terminate GPIO functions directly to the DB-25 connector, we recommend that you use the optional breakout accessory (GPIO-25: Peavey Part# 00510490).
