2−60 CM 4000 Installation and Operating Manual
CONNECTION TO THOMSON/PHILIPS DD SERIES (“DIAMOND”)
An example of hardware connections is shown in Figure 2−72.
• The “Diamond protocol” cable to one of the DD serial ports is required for display of routing switcher status on
the DD console. For cable pin−outs, see page 2−63.
• The “ASCII bus protocol” cable to the DD XBAR port is required if switch commands will be sent from the
DD to Jupiter; for example, when a Venus router is used to provide additional AUX outputs for the DD, or used
to provide Pre−Routing. For cable pin−outs, see Figure 2−73.
• If desired, an MPK control panel could be used for DD Pre−Routing. For cable pin−outs, see page 2−63.
“Diamond” and “ASCII” protocols are set on the Serial Protocol table (page 5−30); and the switcher is identified on the MPK
Devices table (page 5−123).
Installation of MPK panels was discussed on page 2−38.
Refer to the DD installation manual for information about the Diamond serial ports and operating instructions.
