Chapter 3. Setting up the CMG-CD24R6EAM

3.1 Initial Installation

Note: Refer to Appendix E on page 31 for information on connector pinouts.

3.2 Connecting to the Lantronix WiPort NR

The Lantronix WiPort NR has been pre-configured so there should be no reason to change any of the settings. If however you wish to make any changes the following procedure for connecting to the Lantronix WiPort NR should be used:

If you are unable to locate the device or have problems connecting, further information is given at Appendix B on page 20.

3.3 Connecting to the CMG-EAM

The CMG-EAM has been pre-configured so there should be no reason to change any of the settings. If however you wish to make any changes to the Low Latency ports the following procedure for connecting to the CMG-EAM should be used:

If you are unable to locate the device or have problems connecting, further information is given in the EAM manual: MAN-EAM-0003.

Other menu items in the EAM allow for their control and configuration of the CMG-CD24 digitisers, ports and other connected devices.

Any changes made in the EAM to the CD24 settings will be reflected in the Lantronix WiPort NR data output.

3.4 Using the internal mass storage device

The acquisition module has an internal mass storage device which is accessible via the GPIO port (see section 2.2.1.3).

To write to the internal mass storage device:

When a USB host, such as a laptop or PC, is connected to the GPIO port, internal circuitry detects the USB power and automatically connects the Flash memory to the GPIO socket, causing it to behave identically to a standard USB memory stick.

When no power is detected at the GPIO port, the Flash memory is available to the system as if it were a standard removable mass storage device. All of the mass storage device recording options described in the CMG-EAM manual MAN-EAM-0003.

3.5 Warning and error reporting

Each component in the station has a predefined warning and error level. The status of the components are indicated on the EAM homepage.

Green indicators are shown when the level is above 70%

Amber warnings are displayed when the level falls below 70%

Red errors are displayed when the level falls below 40%

The status of all components can be monitored and if the level falls below a set percentage a selected output line can be switched from low to high for use by an external indication system.

To configure the status iolines using the web interface select:

To configure the status iolines from the command line, start gconfig and select “Status iolines assertion configuration” from the top level menu.

3.5.1 Configurable parameters in simple mode

The configurable parameters for recording data in simple mode are shown below:

Enable: Activates the status iolines assertion server.

Warning level: Set the level at which the warning signal is to be triggered.

Line to assert on warning: Select the output line from the dropdown list. All output lines are displayed so care should be taken to choose a suitable output line.

Error level: Set the level at which the warning signal is to be triggered. The error level must be less than the warning level.

Line to assert on error: Select the output line from the dropdown list. All output lines are displayed so care should be taken to choose a suitable output line.

3.5.2 Configurable parameters in expert mode

An additional field is displayed in expert mode:

Log level: The drop-down menu controls the level of detail present in log messages. Not all of the standard syslog logging levels are available. The menu offers a choice (in order of decreasing detail) of:
