LSI-16(e) VTP Interface

Hardware Connection

To communicate with the LSI-16 a connection can be made using a TCP/IP socket on port 8050, or by connecting to the physical RS-232 connector on the back of the LSI-16.

Raw Socket (Ethernet)

• TCP

• Port 8050

• IP Address of the LSI-16/e

RS-232 Connection

• Serial

• Baud 57600

• Stop bits 1

• Parity None

• Data Bits 8

• Flow Control None

Pin 2 - RX Data Pin 3 -TX Data Pin 5 -Ground

The LSI-16 operates as a slave to the third party controller and as a result will only respond to commands sent to it.

The Vocia software is used to enable and configure the TCP or RS-232 connections to the LSI-16. Once the LSI-16 is placed in the configuration, settings can be configured in the LSI-16 General Settings tab.

LSI-16 External Control Configuration

• IP Address -This IP address is used by the third party control system to connect over IP. This port is on the CobraNet network. If control is required from a different network, a router port will need to be configured and the LSI-16 gateway would need to be specified to facilitate this.
• Security-User name and password will be used to authenticate a TCP session. The User Name and Password are case sensitive and must not contain any spaces. VTP Users are limited to a 16 character user name and password. Authentication is not required for a RS-232 session.
• Connection Type – the RS-232 and TCP connection method can be selected here.
• TCP Connections (appear if TCP is enabled as a connection type) Up to four connections can be specified. These connections can be enabled or disabled as required. The connection name is a customizable field that is used as the ‘connection id’ when using the H (Handshake) command.  Each connection name has to be unique and if the connection is enabled, the connection must have a name.
