Connecting to Terayon CherryPicker Re-multiplexer
We encourage you to use the DVB-ASI interface instead of DHEI for MDR/
CherryPicker interconnection due to the limited bandwidth and cabling
requirements associated with DHEI interface.
In the event where you choose CherryPicker equipped with DHEI inputs only, or no
spare ASI input is available, note that Terayon supplies a number of DHEI cables
with the CherryPicker. One is a double-headed Y-cable (part number 009-01139-01).
Depending upon whether it is an IRT or MDR, you must use a different fork of the
Y-cable to connect to the CherryPicker because the DHEI pinouts for the MDR are
different from the pinouts for the IRT. See the diagram below for cable connections
and part numbers.
CAUTION:
On the configuration menu, if the DHEI icon is red, it means that the output
has exceeded the 27 Mbps limit of the interface. You must reduce the number
of programs routed to this output. (See menu R21-G.)
If a lock level protects the current Preset, then it must be reset to lock level 0, before
any modifications to program routing will be allowed (see Chapter 2).
