Refer to the Specifications section of this manual or contact Wohler Sales for more information. The iAM-SUM is compact and simple to operate, with straightforward controls. It has a very wide format touch screen LCD display providing up to 8, 16, or 32 high resolution level meters, depending upon the model.

Important: By design, the supplied AC mains power cord will only plug into a three-prong grounded outlet for your safety. If the plug does not fit into the outlet, contact an electrician to replace the obsolete outlet. 7. Protect the power cord from being walked on or pinched, particularly at plug connection on the equipment and at the socket.

Page 65: Preset Management
Preset Management Presets are monitoring configurations that can be composed of channels from multiple sources and displayed on the meters in any order. Presets should be set up to allow operators to quickly shift between setups for monitoring. The Preset Management screen contains selections of all of the details for a Preset, and is largely arranged in a matrix format connecting input channels to monitoring channels.

Page 77: Preset Replication
Preset Replication Preset Replication allows you to copy presets from a master unit to multiple iAM- SUM units. This can save a lot of setup time if multiple units all need basically the same setup. To start Preset Replication, click on the Preset Replication tab on the master unit. This will start the unit discovery process and will list all the iAM-SUM units that you currently have on your network.
Page 78 Figure 4-22: Preset Replication Target Selection Screen Click either From Master Unit or Select Preset File. This determines the source of the Presets to be copied. Preset Files would be files that you have previously stored in the computer running the Web GUI. You may add a descriptive name or version to the Presets being copied.
Page 79: Import/Export Presets
Import/Export Presets Use the Import / Export Presets page to manage the Preset database in the iAM- SUM. You may export the Preset database onto the computer hard drive for security backup purposes or as a means to transfer it to another iAM-SUM. Likewise, it can be used to import a Preset database from the computer hard drive into the iAM- SUM.
Page 80: Import Configuration

If you have any doubt as to whether you should perform a Factory Reset, do not click the Initiate Factory Reset button. Contact Wohler Technical Service for advice. Factory Reset will also reset your IP address to the default one. After a Note: Factory Reset, the IP Settings will need to be updated.
Page 86: Reboot System
System page is shown in Figure 4-27. This function is normally only used upon request from Wohler Technical Service to troubleshoot or correct an issue. The Reboot System function should be used with a bit of caution. It puts the iAM- SUM out of service for several minutes while it is rebooting, and this may unexpectedly interfere with the use of the product by the remote operator.

Page 97: Appendix B: Dante Network Setup
On iAM-SUM, the AoIP source can be selected through the Source Select option. The iAM-SUM is set up at the Wohler factory to be used as a slave rather than a master within the Dante network. Other devices or software, such as a Dante Controller, are expected to be responsible for most device configurations and all audio routing.
Page 98 Card ID will be shown in red, e.g. Wohler-xxxxxx where xxxxxx is the last 6 hex digits of the card MAC address as shown in B-1. This usually indicates that the IP address of the card is not in the same subnet as the Dante Controller host.
Page 99: Dante Tm Device Setup
Dante Device Setup The iAM1-SUM default Dante Device Name is “Wohler- …” followed by the last 6 digits of the Dante port MAC address, as shown in Figure B-2. This name can be changed by the Dante Controller to appear that way on the network, but that will not change the iAM-SUM unit name appearing on GUI pages and iAM-SUM Remote Metering or Discovery pages.

Important: Only 44.1 kHz and 48 kHz audio sample rates are currently supported by the iAM-SUM. The Brooklyn II card would accept a Dante Controller command to operate at other rates, without giving an indication it will not be implemented.

AES67 The iAM-SUM Brooklyn II can be configured for AES67 operation. Refer to Figure B- 5. AES67 operation with Dante is limited to eight or less receive and transmit channels at 48 kHz sample rates. 24 bit linear (L24) encoding and 1 msec packet time are fixed default transmit parameters.

Page 105: Appendix D: Ravenna (Zman) Setup
APPENDIX D: Ravenna (ZMAN) Setup Introduction Installing the iAM-SUM into an existing and functioning Ravenna network using the Merging ZMAN Card is virtually plug and play. The iAM rear panel AoIP jack supports 1Gb/s and 100Mb/s Ethernet devices in Ravenna Audio over IP network configurations.
Page 106: Configuring The Aoip Merging Option Card
The Merging Ravenna card runs specific firmware from Merging and augmented by Wohler for use within the iAM-SUM. The card will not function correctly if the user downloads and installs firmware from any source besides Wohler. The Wohler augmentation includes the ability to support 64 channels.
Page 107: Getting Started | General Settings
on that line and select Web Services: Advanced (or Ravenna) to bring up the Merging Ravenna configuration page. Also, the ICON of the card will appear in the main part of the Aneman screen. Double Clicking on the ICON also will load the Configuration screen.
Page 108: Getting Started | Ptp
Getting Started | PTP This tab is shown in the following figure. This configuration page refers to how your Ravenna network is synchronized to clocks. Figure D-2: Getting Started | PTP The elements of this tab are as follows: 1. Global Settings: The default value for PTP a.
Page 109: Getting Started | Session Sources
3. Status: a. Lock: This shows if the device is locked to PTP (Locked -Locking - Unlocked) b. Master: This is true or false for the current device. c. GMID: This is the current GrandMasterID (PTP Master) d. Delta (ns): This is the time delta between the device and the PTP master.
Page 110: Getting Started | Session Sinks
8. Payload type: RTP Payload type - This value should not be modified. 9. Codec: The possible bit rate values are L24, L16, DSD64, DSD64_32, DSD128, DSD128_32, and DSD256. Note that these values are sampling rate dependent. 10.Frame size (samples): This the frame size of the current source. 11.DSCP: The audio DSCP should be set to 34 for RTP AES67 or 46 for RTP Ravenna.
Page 111: Getting Started | Session Info
5. Manual: This allows manual entry of an SDP. 6. Delay (samples): This sets the playback delay. 0 is automatic delay. 7. Ignore RefClk GMID - accept source locked to any PTP master: This feature is useful when you want to connect a stream through Internet (for example with two PTP Masters (GPS) at each location.
Page 112: Getting Started | Ins/Outs
Getting Started | Ins/Outs This tab allows you to change the name of the specific Inputs and/or Outputs. Figure D-5: Getting Started | Ins/Outs Getting Started | I/O Router This page allows remapping of incoming channels to different internal channel assignments.
Page 113: Operation
Operation: Connecting Remote Source to Local Sink This instruction assumes another Ravenna device is active on the network and sourcing a multicast stream. The Merging Configuration section for Session Sink controls how to configure the card to receive the stream and provide it to the IAM interface for display on meters and speakers, etc.
Page 114 Figure D-7: Session Sinks Tab To avoid confusion if monitoring more than one Flow, especially if the various source Flows have overlapping channel numbers, use the matrix to direct Flows to higher channel ranges. For example, for monitoring 2 SDI sources (four 8 channel Flows), assign two flows to 1-8 and 9-16 and the next SDI signal to 17-24 and 25- 32.

Figure D-8: Session Sources Tab ZMAN Updating The Zman card is pre-initialized with the correct Wohler firmware load. In case of future upgrades, use the following steps: 1. In Aneman, right click the ZMAN entry on the bottom Devices section, and select Maintenance Mode.
Page 116: Appendix E: Api Documentation
APPENDIX E: API Documentation Introduction This appendix discusses ways to use the Application Program Interface (API) to allow third party equipment to remotely access options and settings of the iAM- SUM. It includes specific code examples for commonly used requests. The API uses JavaScript Object Notation (JSON) as its communication language.
