CIU Emulation
Part No.: 4417589_Rev13 Protocol Manual - CIU Emulation
CIU 888 1 - 11
In MSU mode, requests are handled according to the diagram shown in
FIGURE 1-9.
FIGURE 1-9 Diagram for handling of requests in MSU mode (MSU mode enabled)
If, in Normal mode, a request is sent to a gauge connected to a
downlink CIU, and the address of the CIU or the address of the gauge
does not match, time-outs will occur and notifications of these time-outs
will be sent to the host system. In MSU mode, on the other hand, no
time-out replies will be sent.
1.4 CIU Emulation in a redundant setup
If two CIU 888s are configured as a redundant pair and CIU Emulation
is enabled, GPU requests sent to the secondary CIU 888 will be
ignored.
NOTE: Refer to the Configuration Manual CIU 888 (Part No. 4417584) for more
