Personal Greeting

The 9611B switch and distribution system is an intelligent switching, monitoring and distribution system, packaged in a 1U rack-mount chassis.
The 9611B can be set up to distribute a wide range of signal formats; low noise sine waves, IRIG timecodes or pulse formats from either one of two inputs to all twelve outputs. The 9611B allows the user to deploy one model type to support multiple signaling formats which lowers support and logistics costs.
The 9611B provides for both manual and auto-switching signal distribution. When in auto-switching mode, the 9611 will detect any input or output failure based on the signal type being propagated. In the Auto mode, any input failure causes the unit to switch from Primary to Secondary source. Alarms will be indicated by all user interfaces including the front panel and Command Line Interface

 User Interfaces 

The 9611B is controlled through two user interfaces: front panel controls and indicators, and a command line interface (CLI) over a RS-232 serial port connection. 

Front Panel Controls and Indicators 

The 9611B processes two signal inputs (A and B). Either input may be designated primary and the other as secondary. In auto mode, the unit will automatically switch from primary to secondary in the event that the primary input fails. There are three push buttons (input A, auto, and input B) that allow the input mode to be selected. Pressing input A or input B will force the selected input to be sent to all channels to use the selected input. Pressing auto will activate the automatic switchover mode. The twelve LEDs, numbered one through twelve, are either green to indicate that the channel signal is present and active or red to indicate that the channel signal has failed.

 When any alarm (A, B, or 1–12) is set, the alarm indicator turns from green (normal) to red (alarm). Once the failure is remedied, the alarm can be deactivated by pressing the alarm pushbutton, or issuing a command over the CLI. If the alarm is cleared, all alarm indicators return to the normal green color. 

Command Line Interface 

The 9611B instrument has a serial port interface. Communication between the instrument is achieved by running a communications program on a PC and connecting the RS-232 serial ports of the PC and 9611B through a serial cable.

 Certifications

Safety 

  • UL: 62368-1 
  • CSA C22.2 NO. 62368-1 
  • IEC/EN 62368-1 

 

 

Key Features

  • Supports multiple signal formats: IRIG time codes, pulse formats and low noise sine waves.
  • Enables redundant inputs: When in auto switching mode, it detects input failure and automatically switches to the redundant input without signal loss.
  • 12 outputs: Low noise, high isolation amplifiers allow for 12 copies of each input to be distributed without degradation of downstream equipment. This enables system designers to reliable distribute highly accurate RF time codes and 1pps signals.
  • Front panel controls: When one input fails an alarm will indicate such failure through the front panel controls and indicators.
  • Command line interface: The 9611B has a serial port interface that supports communication programs with a PC.
