Open or Closed. The Relay port specification is dry contact, 75mOhms, 2A @ 30VDC, 0.5A @ 125VAC. The mini stereo plug should be wired as shown in the following diagram.

Activity LED

The Activity LED behaves differently depending on the Part Number of the Main Board. On appliances where the Part Number ends in 2, the Activity LED blinks green when there is Ethernet activity. On appliances where the Part Number ends in 3 or higher, the appliance has a tri-color LED that shows different status activities as shown in the table. (To determine

part number, open IWS and go to Status: User Information > Main Board > Part Number.)

The tri-color Activity LED blinks at one-second intervals in the following sequential order:

Table 21. Tri-Color Activity LED

Clear

Off; no activity

 

 

Green

Ethernet activity

 

 

Red

If there is TX or RX activity on COM1

 

 

Orange

If there is TX or RX activity on COM2

 

 

Event Triggering

The VB6000 event triggering feature lets you use an external switch to control the function of the VBrick. This section provides some examples of how to use this feature. In all the examples, a high event is triggered when the switch is closed and a low event is triggered when the switch is opened. The event trigger inputs on the VBrick recognize a high voltage anywhere above +8 volts DC with an upper limit of +12 volts. A low voltage is anything at or below 0 volts DC with a lower limit of -12 volts. The event can also be configured to run a script on Pin 7 or Pin 8 depending on how the connection is configured. See "Configuration: Script Management" in the VBrick MPEG-2/4 Appliance Admin Guide for configuration details; see RS-232/422/485 COM Port Pinouts for pinout details.

Note You cannot execute a script either with the IR Remote Control or using an event trigger if IWS is currently running in Edit mode. If you run a script directly from IWS, it automatically exits Edit mode and terminates the active editing session.

Example 1

Connect an external power supply (+8V to +12V) and a switch directly to the ground pin and an event pin of the COM1 port on the VBrick.
