DCP control

This mode allows direct control of a single ServSwitch 4site Flex by means of a control device, for example, a computer. The control device can query and change the mode of ServSwitch 4site Flex.

ServSwitch 4site Flex responds to each DCP message sent by the control device with a DCP reply.

This reply includes the values of all settings queried or set by means of the last message. If the message sent by the control unit contains errors, the ServSwitch 4site Flex will reply by sending an error message.
