Figure 4-21. DCP synchronization example.

To synchronize, ServSwitch 4site Flex 1 sends every change in settings as a DCP message via the serial Y to the RX input of ServSwitch 4site Flex 2.

ServSwitch 4site Flex 2 adopts the settings and sends a DCP message via TX output over the Y cable to the RX input of ServSwitch 4site Flex 3.

The synchronization chain can be any length.

Do not connect the last device in the chain to the first device (that is, do not create a loop).

Security Levels

The security level settings in the OSD menu previously described also apply to control via DCP messages. Queries are possible up to Security Level 7.

Table 4-1 shows the maximum security levels for simple element settings. These settings may be changed via DCP up to the specified protection level.
