4. Connect two video sources to the bus A and bus B inputs of the MKE-3901.
By selecting different sources on the program bus you should see the
program output toggle between the two sources.
Internal Router Control (NEO NSM)
1. Verify correct settings on the NSM modules.
• The “first” NSM, which is used for inputs 1-5, should be set to Level 0,
SrcOffset 1, DestOffset 0.
• The “second” NSM, which is used for inputs 6-12, should be set to XY
Level 1, SrcOffset 1, DestOffset 0.
2. Verify that external router control is not selected in the System Config
section of the ICU. Some versions may have a check box to select internal
routing, otherwise deselect external. Any changes need to be uploaded to
the frame.
3. Verify that LockStat 1 and LockStat 2 parameters on the NSM module are
set to Free.
External Router Control (Panacea, Platinum)
1. Verify jumpers on MKE-3901 module are set for RS-232 or RS-422 control.
2. Verify jumper pack on breakout module is set for RS-232 or RS-422.
3. Verify cable pinout is correct for RS-232 or RS-422 connection to the
router.
4. Verify the router serial port is correctly set for RS-232 or RS-422.
5. Verify that the router serial port is set to 38400 baud.
6. Verify that the serial cable to the router is connected to port E on the
breakout module.
7. Verify that the level, source, and destination setup in the System Config/
External Router Configuration of the ICU and wiring match.
Audio Overs
When using the breakout module the audio over jumpers on the MKE-3901
module must be set to balanced, even if unbalanced AES inputs are used.
Software/Firmware
All software and firmware components must be from the same release. If one
component is upgraded, the entire system must be upgraded.
