Set COM Configuration

Use the COM Configuration tab to view and change the communications parameters for a device selected in the IP Link® Tree window.

To view or change the COM configuration settings:

  1. In the IP Link Tree window, select a device port.

  2. Select the COM Configuration tab (see below).

  3. In the Serial Port Settings section, select a device.

  4. View or change the COM port settings as desired.

Note:  If a device driver has been associated with a port, only the Baud Rate field can be changed.  The other communications parameters are set by the device driver and cannot be changed.

Pass Through Configuration

Note:  The Pass Through Configuration option applies to the following products only:

  • IPL T SFI244

  • IPL T SF24

  • IPL T S2, S4, and S6

  • IPL 250

The Pass Through Configuration option allows you to install an IP Link device into an existing A/V network to remotely monitor and control the A/V devices within the network.

Example

You can connect an IPL T S4 between an MLC 206 and a projector, with the MLC 206 connected to serial port 1 and the projector connected to serial port 2.  This allows you to remotely control both the MLC 206 and the projector.  If you then connect serial port 1 and serial port 2 using the Pass Through drop-down list, a connection is established between the MLC 206 and the projector, so that the existing MLC 206 can continue to send control commands to the projector.

The Pass Through Configuration settings include:

  • Pass Through – This drop-down list allows you to select which pair of serial ports to connect using the pass-through option.

  • Timeout – Identifies the length of time the IP Link device waits for a response from the connected A/V device before it will stop waiting and looks to another port for communication signals.  If the Use Delimiters check box is not selected, response wait time will always be dependent on the timeout value.  If the Use Delimiters check box is selected, the IP Link device first waits for a delimited response, and if none arrives within the allotted timeout period, the IP Link device stops waiting and looks to another port for communication signals.  The timeout value is set in units of 10ms.  A value of 100 would be 100 x 10ms = 1 second.

  • Use Delimiters – Delimiters are characters that indicate the end of a command to or a response from a device.  There are two types of delimiters: character and length.  In this section, you are only concerned with the response delimiters from the A/V device that is connected to the IP Link device.  Here, you indicate whether the IP Link device should expect a character-delimited response, or a length-delimited response.  In the majority of configurations, the device driver sets the delimiter option, and you do not have to adjust it.

  • Character Delimiter – The end of a command or response is identified by a specific ASCII character, such as a carriage return (CR).

  • Length Delimiter – The end of a command or response is identified by a specific string length of characters, such as 8 bytes.

To configure the Pass Through option:

  1. In the IP Link Tree window, select a serial port.

  2. Select the COM Configuration tab (see below).

  3. From the Pass Through drop-down list, select a second serial port.

  4. Set the desired timeout value.

  5. Select delimiters, if desired.
