DCP synchronize
,
which keeps several ServSwitch 4site devices in the same display mode.
Default setting is “off”, which prevents any external CONTROL.
Use a serial cable to connect a control unit to the RS 232 port (RJ 45) on the ServSwitch 4site rear panel.
To synchronize several devices, special Y cables are required.
Settings for the connection are:
Transfer rate 57600 baud, 8 data bits, no parity, 1 stop bit, no

DCP control
This mode allows direct control of a single ServSwitch
4site by means of a control device, e.g. a computer.
The control device can query and change the
mode of ServSwitch 4site.
The ServSwitch 4site 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 will reply by sending an error message.
