Installing and Controlling Third-Party Devices
Nelson Interfaces: Installation

Hardware Installation

Device Connection:

For information about how to connect the Nelson Interfaces, refer to  Nelson Interfaces: Connections

Device Settings:

Type 901

Set DIP switches 6 and 7 to ON and all other DIP switches to OFF.

Type 941

For the type 941, only DIP switches 1, 2, 3, and 7 are relevant. They are set to OFF by default.

Restrictions:

With the Nelson Interface 902, only one channel is supported.

No drivers are available for the type 940, all previous types (with 700 or 800 numbers), and for the Perkin Elmer Analytical Interface.

 

Software Installation

Install the Device Driver in the Chromeleon Server Configuration. (For more information about the program, refer to Software Installation and Communication  The Server Configuration Program.)

  1. Start the Chromeleon server.

  2. Start the Server Configuration program.

  3. Add the Nelson Interface to the selected timebase.(Select Add Device on the Edit or context menu, and then select Nelson (or Perkin Elmer) from the Manufacturers list box and 941 Interface (or 950/960/970 Interface) from the Devices list box.

  4. The following settings are required:

On the General tab page, select the port address to which the interface is connected.

On the Remote Inject tab page, configure the integrated Remote Inject driver.

On the Signals tab page, you can make special settings for single signals.

 Note:  

The Nelson Box 901 is a single-channel version. Therefore, do not install the second channel that is provided by the driver!

On the Relays tab page, verify that the corresponding relays are selected by the check box.

 Note:  

As standard, the Nelson Box 901 has two relays only (Ready and Relay #1), but the Nelson 941 Interface driver also knows relays 2-7, which, however, are optionally available only.

The Error Levels tab page classifies the severity of any errors that occur. It is generally not necessary to change the default settings.

Application

Nothing particular known.
