Section 5 – Electrical Interfaces
5.0 DVB3030 Connections
All DVB3030 connections are made to labeled connectors located on the rear of the unit: The
connector definitions below are those on the DVB3030 unit. Any connection interfacing to the
DVB3030 must be the appropriate mating connector. Refer to Figure 5-1a and 5-1b for connector
locations.

5.1 AC Power
The unit is powered from a 100 – 200 VAC, 50 – 60 Hz source. Maximum unit power
consumption is 25 W. The switch turns power on and off to the unit. A chassis ground
connection can be made to the stud located to the lower right of the AC Power Connector.
5.2 Ethernet Interface (I/O)
The Ethernet Interface (J11 for DVB3030, J8 for DVB3030L) can be used for the monitor &
control functions of the unit. The physical interface is a standard RJ-45 Connector. Refer to
Ethernet Port User Interface (Section 4.4) for programming details.
5.3 External Reference (Input)
The External Reference Input (J5 for DVB3030, J3 for DVB3030L) is supplied to allow the
customer to phase-lock the modulator’s internal oscillator to an external reference.
This female BNC Connector accepts a 1.5 – 5 Vp-p @ 50 Ohms. The frequency range of the
external reference is 1 -–10 MHz in 8 KHz steps.
5.4 Remote Port (I/O)
The Remote Port Interface (J4 for DVB3030, J7 for DVB3030L) can be used for the monitor and
control functions of the unit. The physical interface is a female 9-Pin D-Sub Connector. This bi-
directional port complies with RS-485 Electrical Specifications. Refer to Remote Port User
Interface (Section 4.3) for protocol and programming details. Pinouts are listed in Table 5-1.
