terminal matching for the M4 fastening bolt. After that, the washer and the nut
have to be tightened again.
Next, establish the external Ethernet connection by plugging an Ethernet cable
from your network to the "Ethernet" port (9) of the device.
If the basic network setup via serial interface (chapter 4.4.2.2) is required, and/or if
it is intended to control the device via the serial interface using Sandar Prosan pro-
tocol, Leitch protocol, or QEC protocol, a serial connection between a PC and the
serial connector labeled "RS 232" (8) is to be established using a 1:1 cable. The
configuration of the serial interface is described in chapter 4.4.1.
If it is intended to control the DEV 1951 via the digital interface (chapter 5.4),
connect a prepared cable to the connector labeled "DIG/In" (7); the pin assignment
of the digital interface connector is stated in chapter 7.
If required, connect a prepared cable to the connector labeled "Alarm" (6); the pin
assignment of the alarm connector is subject of chapter 7 as well.
