Axon has an extensive technical product support department. Herewith a complete overview of frequently asked questions, subdivided per product. Please contact our support department if you need additional information.

• Can the SAV08 have black burst on green in RGB output mode?
  Close

  Can the SAV08 have black burst on green in RGB output mode?

  No the SAV08 can only have syncs on green in RGB output mode.
• Is it possible to change the preset by the GPI Contacts on an Aspect Ratio Converter (ARC)?
  Close

  Is it possible to change the preset by the GPI Contacts on an Aspect Ratio Converter (ARC)?

  Yes, on the ARC20, ARC2000 and ARC3000 you can change the presets of the ARC by the external GPI contacts.
• Is it possible to use a distribution amplifier in a DVB/ASI environment?
  Close

  Is it possible to use a distribution amplifier in a DVB/ASI environment?

  Yes, but some outputs are inverted. In SDI the polarity is not of importance. Different is DVB/ASI. There it is of importance that there is no inversion. When a inversion is required it can be achieved by adding a ST1-R or on special request a hardware upgrade is possible.
• Is the SAV10 able to process NTSC50Hz?
  Close

  Is the SAV10 able to process NTSC50Hz?

  No.
• Is your legalizer legalizing in chrominance or also in luminance domain?
  Close

  Is your legalizer legalizing in chrominance or also in luminance domain?

  The SDL3000 legalizer legalizes chrominance and chrominance + luminance
• On the DAC24 an AES/EBU input signal with 48 Khz, 0 ppm gives at the output + 600 ppm? How can this be avoided?
  Close

  On the DAC24 an AES/EBU input signal with 48 Khz, 0 ppm gives at the output + 600 ppm? How can this be avoided?

  The reason is that the sample rate converter is switched on. To avoid this the sample rate converter has to be switch to transparent.
• The Synapse network seems to perform poor. How can we find the source of our problem?
  Close

  The Synapse network seems to perform poor. How can we find the source of our problem?

  Often times the network is loaded with Announcements due to a misconfiguration of a card or due to problems in your signal chain. Statuses can toggle with high frequency. SynapseSetup has a debug window which will show these Announcements if you enable this. In SynapseSetup Goto Configuration -> Debug tab -> select Show Annoucements and press OK. Goto View -> Debug log and a white text window appears in the lower dock. Both the source IP address and slot numbers can be used to trace the source. The ObjGrp and ObjID numbers point to the originating menu items. An ObjGrp of 3 indicates a status change message. ObjGrp 4 is an event message. The ObjID is the menu item within a group. 0 is the first item, 1 the next one etc.
• We need to upgrade a card with an SPF file. The rack-controller has no SPFSx files.
  Close

  We need to upgrade a card with an SPF file. The rack-controller has no SPFSx files.

  The software version of the rack-controller must be greater than 0300 for *.spf file support. You can find this version under the 'Identity' items using SynapseSetup or in the 'About' items using the front panel menu. Contact Axon support if the software version is not higher than 0300.
• What are the mNM and mGW settings in the rack-controller for?
  Close

  What are the mNM and mGW settings in the rack-controller for?

  These are used when you assign a 'manual' IP address to your rack-controller. You MUST set the mNM, otherwise your frame might not be reachable or it cannot Announce status changes or events. mGW is required when you need to access your frame from outside the local network.
• What happens when the AES/EBU audio input bit stream is cut completely? What is the effect on the AES/EBU output?
  Close

  What happens when the AES/EBU audio input bit stream is cut completely? What is the effect on the AES/EBU output?

  Output is muted.
• What is an UES ERR, EDH ERR, EDA ERR, IDH ERR, IDA ERR (ERR= error)
  Close

  What is an UES ERR, EDH ERR, EDA ERR, IDH ERR, IDA ERR (ERR= error)

  According to SMPTE RP165 it is possible to have an error detection and handling system. This system includes several error statuses. UES ERR; unknown error status. It signifies that a serial signal was received from equipment not supporting this error detection practice. EDH ERR: error detected here. It signifies that a serial transmission data error was detected. In the case of ancillary data, this means that one or more ANC data blocks did not match its checksum. EDA ERR: error detected already. It signifies that a serial transmission data error has been detected somewhere upstream. If device B receives a signal from device A and device A has set the edh flag, when device B retransmits the data to device C, the eda flag will be set and the edh flag will be unset if there is no further error in the data. IDH ERR: internal error detected here: It signifies that a hardware error unrelated to serial transmission has been detected within a device. This is provided specifically for devic es which have internal data error checking facilities, as an error reporting mechanism. IDA ERR: internal error detected already. It signifies that an idh flag was received and there was a hardware device failure somewhere upstream. UES ERR: unknown error status. It signifies that a serial signal was received from equipment not supporting this error-detection practice.
• What is EDH?
  Close

  What is EDH?

  EDH is ERROR DETECTION HANDLING. According to SMPTE RP165 it is possible to have an error detection and handling system. In the SDI stream is a flag set (checksum). This flag is set in the SDI encoder and is transported through the whole SDI chain. At the last stage the checksum must be still intact. Otherwise an alarm status will be generated.
• What is the delay of ARC20?
  Close

  What is the delay of ARC20?

  Selectable between 1 frame and 1 frame - 7 lines.
• What is the function of the Announcements setting in a card?
  Close

  What is the function of the Announcements setting in a card?

  A card can generate several alarms like , lost of input etc. If it is set to zero all spontaneously generated messages from the card are disabled. When set greater than zero both status updates and events are sent from the card which owns the setting. The Annoucements setting can be used as 'emergency brake' to prevent that the network becomes flooded with unwanted Announcements.
• What is the procedure for upgrading our rack-controller?
  Close

  What is the procedure for upgrading our rack-controller?

  This procedure is described in the rack-controller manual in the 'Files' chapter. For rack-controllers shipped with a version below 0900 you should use an *.a90 file and SynapseSetup version 1.1 or 1.2. Rack-controllers shipped with 0900 software can be upgraded with the latest SynapseSetup using an *.spf file.
• What to do if the front panel LCD shows 'I2C_NAK' and the rack-controller locks up?
  Close

  What to do if the front panel LCD shows 'I2C_NAK' and the rack-controller locks up?

  This is a bug in the 0400 software of the RRC10. Contact Axon support to get the latest software.
• What use has the Broadcasts setting in the rack-controller?
  Close

  What use has the Broadcasts setting in the rack-controller?

  When set to 'On' Announcements are broadcast on the local network. This is used to synchronize multiple PCs on the local network monitoring the Synapse frame for status changes and events.
• What use has the Forwarding and FW settings in the rack-controller?
  Close

  What use has the Forwarding and FW settings in the rack-controller?

  When set to 'On' the FW IP address is used as an additional Annoucement destination inside or outside your local network. In SNMP enabled rack controllers this setting is used as trap destination.
