“RAM DATA BREAK” is displayed
When the power is turned on, data check is automatically performed on the back-up
RAM.
If the data is damaged, the window with a message “RAM Data Break” is displayed on
the screen. In this case, either the factory data or user data is loaded to RAM. (User data
has higher priority)
If both of them are damaged, the RAM data is reset to the initial values. After the setting
is completed, press [OK]. You will see which data is loaded under “RAM Data Break”.
Note :
If this message is often displayed, the back-up RAM may be damaged.
10.5 Trouble During Firmware Update
If the power of MCP-300 is turned off during firmware update, perform the update
process again for MCP-300.
Reference:
Please refer to "9.1. MCP-300 Update" for the method to update MCP-300.
10.6 Trouble with Network Connection
In network operation, the connected devices may simultaneously experience a
malfunction. This is due to network failures, and therefore, the command control cannot
be performed normally. There are some possible causes for network failures.
࣭
W Wiring failure
Check coaxial cables, coaxial connectors, F connectors, and 75

terminators. Many
network failures are caused by these items.
The shield part of coaxial cables (coaxial connectors) used to connect to the network
is different from video signals (i.e. not GND but signal wire). If they are connected
to GND by mistake, this can cause a network failure due to loss in signal level.
࣭
Mistakes in network ID settings
If there are duplicates in ARC ID for ARCNET and IP Address for Ethernet, this can
cause a failure in a whole network, as well as, the devices with duplicates.
For the MCP-300, ARC ID and IP Address can be displayed on the information
screen. Make sure there are no duplicates in other devices.
࣭
Device failure
A network failure can be caused by a failure in a certain device. Each device must
be temporarily disconnected to find the device with the failure. The MCP-300 can be
disconnected from the network by pressing and holding the PM IND switch to
display the update screen. Press the PM IND switch again to return to the network
again. Similarly, the OCP-300 can be disconnected from the network by displaying
the update screen.
