Yes. To connect the HDL300 system with Cisco Telepresence® SX80 Codec, two custom cables are needed to accommodate the standard 3.5mm jack connector on the HDL300 system's connect module with the standard Euroblock connectors on the Cisco I/O panel.
Creating custom cables
Cable 1: Prepare a 3.5mm jack cable with the three pins positive (+), negative (–) and ground (), wired to an appropriate Euroblock 4-conductor terminal block per the SX80 User Manual microphone inputs. Leave the microphone Mute pin unused.
Cable 2: Prepare a 3.5mm jack cable with the three pins positive (+), negative (–) and ground (), wired to accommodate the SX80 speaker Output Left & Right terminal connections by tying the two negative (–) and two ground () lines together.
On the connect module
- Plug Cable 1 into the Aux out port
- Plug Cable 2 into the Aux in port
- Connect the PoE cable (provided) to the RJ45-1 port on the connect module to the rear RJ45 port on the HDL300 system
- Plug in the 54VDC power supply
On the Cisco Codec
- Plug Cable 1 Euroblock connector into Microphone Input Channel 1 on the rear SX80 I/O panel
- Plug Cable 2 Euroblock dual terminal connectors into Speaker Output Channel L & R
- Connect the Cisco Codec to the network via the LAN port
- Plug in the 110/240VAC power source
In the SX80 CODEC control software
- Set "Audio Input Mic Type" to Line
- Set Microphone controls "Echo Control", "Noise Reduction" and "Dereverberation" to OFF
NOTE: The Nureva® Aux In / Out connections are single-ended, unbalanced signals with default maximum output signals as given in the table below. Any equipment requiring voltages below these levels may result in clipping, distortion and, in extreme cases, damage to connected systems. Equipment requiring voltages above these levels will not be adequately driven by the HDL300 system’s output signal and may result in quiet / no audio on the channel. Before connecting to the Nureva Connect Module, make sure the third-party device voltage levels are adequate or adjusted properly by additional interfacing hardware.
