This test run mode is provided to support testing scenarios where using the GUI (user interface) on a PC or other device is impractical or undesired. A typical usage case is where the driver of a vehicle will also need to control test starts and stops with minimal effort and distractions. This is applicable to many vehicle tests, but is most common when running proving grounds tests on motorcycles, snowmobiles and other “single occupancy” vehicles.
See the technical note Long term unattended testing considerations for more information about start and stop of long term testing.
To use the Remote test control mode, the user must configure the SXR test to use the Remote control run mode. In Test configuration, select the Setup menu item in the Task pane. Under Test run mode options, select Remote Control from the drop down menu.
On the CX23-R
The user must also provide and connect a control switch to the CX23-R AUX port cable (1-KAB2108). A single pole-single throw switch is recommended, as shown in the wiring diagram below.
NOTE
On the CX23-R, if a switch is not connected to the AUX port, the system detects this as logic 0 and does not start a test as soon as remote control is enabled.
On the EXRCPU and the EXRLCPU (operating as the eDAQ does), if a switch is not connected to Input 1 on the power connector port, the system detects this as logic 1 and starts a test as soon as remote control is enabled.
Suspend mode
Unlike the Normal test run mode, the Remote control test mode requires that the SXR test be enabled (initialized) before any test run can be started. See Running a test for details on this. One topic not discussed in that section is suspending the remote control mode.
Once enabled, the Remote control test can be put into suspended mode at any time using the user interface (which of course requires a PC or other GUI supported device to be connected). On the CX23-R, the position of the AUX port switch is ignored in suspended mode.
The user may want to put the test in this mode when the test is enabled. For example, a short test can be interactively started and stopped to verify that everything is working as expected before resuming the switch controlled mode (i.e., taking the test out of suspended mode) and disconnecting the PC.
Note that the user interface can still be used to view run time display charts and download SIE files independent of whether the remote control test is in suspended mode or not.
