2 Connecting NEO to the World

NEO has a total of three different ports that are used to connect it to the world. Likely, the first port that will need to be connected is the RS-232 port.

2.1 RS-232 Port

The RS-232 port is used for initial setup purposes only. It is a standard DCE pinout allowing a straight through DB9 cable to connect it to a computer or other terminal device for setup. Default baud rate is 19200,N81.

2.2 Ethernet Port

The Ethernet Port is used for setup of the NEO as well as for its operation from the consoles. Control of its relays is handled through this port. The NEO sends multicast packets whenever status of one of its relays or inputs changes allow for all users of the device to see real time changes in parallel. The port supports both 10 and 100 Mbps operation of standard Cat 5 cable.

2.3 Relay/Input Ports

There are 10 RJ45 ports that are used to sense inputs and control external events. Each connector is connected to a DPDT relay. Both sets of poles are brought out

to the connector allowing for two separate	1 2 3 4 5 6 7 8	1)	Relay1 N/O
circuits to be controlled by a single relay. Figure		2)	Relay1 Common

relay and “Relay2” the other half. The relays are		6)	Relay2 N/C

is a diode blocked input that allows sensing of a		Connector View
logic signal. The input range is 0-18 volts.

Exceeding the limits of either the Input or the

Relays is a violation of the warranty. The

manuals of the various Vega VoIP consoles should be consulted for programming the user interface buttons to control the relays and sense the inputs of the NEO-10.
