Dispose of used battery properly. Keep away from children. Do not disassemble and do not dispose of in fire. The CMN-91 can be operated by plugging in the external power supply that is shipped with every unit. However, the unit also can be powered by a customer-supplied lithium ion battery. In order to use the lithium ion battery, the optional battery mount must be ordered.
If the battery mount was not purchased with the unit, perform the following: 1. Remove the portable case from the CMN-91. Set all mounting hardware aside, as you will use it to reinstall the portable case. 2. Remove the cover from the CMN-91. Set all mounting hardware aside, as you will use it to reinstall the cover.
Rack Mounting the CMN-91 CAUTION The CMN-91 should not be installed in a DRC-1 case. If installed in a DRC-1 case, the unit will overheat. When selecting the permanent mounting location for the CMN-91, make sure that the flow of air to the ventilation holes on the top and sides of the chassis is not obstructed.
To mount the CMN-91 into a DRC-3 rack mount without rack extensions, follow these steps: 1. Slide the CMN-91 unit (ITEM 1) in the DRC-3 rack case (ITEM 2). 2. Using ¾-in. Phillips head screws (ITEM 3) and lock washers (ITEM 4), secure the CMN-91 unit to the front of the DRC-3 rack case.

To mount the CMN-91 into a DRC-2A rack mount case, follow these steps: 1. If the optional bracket kit is being used, install the bracket (ITEM 14) to the rear of the CMN-91 unit. 2. Install the extension bracket mounts (ITEM 2) to the unit (one on each side) using #8 kep nuts (ITEM 3.
6. Tighten all screws and nuts, securing the assembly. 7. Insert the CMN-91 into either front opening of the DRC-2A. Slide the unit into the DRC-2A until it seats fully against the back flanges of the DRC-2A, and the bezel of the CMN-91 is fully seated around the front of the DRC-2A.
Subnet Mask: 255.255.255.192 Gateway: 255.255.255.255 1. Prior to performing the CMN-91 network configuration, obtain TCP/IP addresses from the system administrator or the Internet service provider (ISP). These addresses are a static IP address (unless using Dynamic Host Configuration Protocol [DHCP]), a subnet mask, and an optional gateway IP.
The Imagine Communications Device IP Configuration Utility is used to set the IP network settings of your Imagine Communications device(s). This utility is used to set the network settings for the CMN-91 and the RCU-CMS. This utility is also used to manage the IP list in the RCU-CMS that directs the RCU connection to the CMN-91 and other compatible Imagine Communications products.
Once installed, the IP configuration utility is ready to use. 1. Locate the Imagine Communications Corporation group in the Windows program list. 2. Navigate to the Imagine Communications Device IP Configuration Utility group, and then select the Launch DevIPConfig.exe shortcut.

The CMN-91 can be used to set the gain amplification in the video signal using the GAIN button. The vertical gain setting appears in the upper left portion of the waveform display. The horizontal gain setting appears in the upper-right portion of the waveform display.
Gain is used to set the range of the amplification in the video signal. The standard gain in the vector is x1.0. The CMN-91 can be used to set the gain amplification in the video signal using the Gain button. The gain setting appears in the upper left portion of the vector display, as shown below.
Operation Audio Display The CMN-91 accepts one AES/EBU and up to four groups of embedded audio inputs. Any two input channels can be selected to be monitored on the headphone output. To access the audio display, press and release the AUD function button.
When the next alarm occurs, the previous alarm moves down one position. The CMN-91 unit has enough memory for 100 alarms per input. When 100 different alarm events have occurred, alarm number 100 is dropped and the most recent alarm is tagged as 01.
Time Code Source Setup Menu The Time Code Source setup menu is used to determine the Time Code Source for each format. The CMN-91 can read Longitudinal Time Code and Digital Vertical Interval Time Code based on the format selected.
The Import/Export Setup menu is used to allow import and export of display captures stored on a USB device. The File Navigation screen appears only when a USB drive is attached to the CMN-91 unit. See File Navigator (on page 123) for more information.
