| Summary | Sets the device number to be controlled using the active axis. |
Note: This setting affects only the active axis. See the Set Active Axis Command #25 for instruction on how to select an axis.
Valid command data values for setting an axis device number range between 0 and 254. Once a axis device number is set, the setting is stored in non-volatile memory and will persist after power-down or reset.
To restore the joystick to its factory default settings, issue a Restore Settings Command #36. The factory default settings for axis control are as follows:
- Axis #1 controls Device #2
- Axis #2 controls Device #3
- Axis #3 controls Device #4
Example: Suppose you would like to assemble a 3-axis system where:
- Joystick axis 1 (right / left) controls device #3.
- Joystick axis 2 (up / down) controls device #4, but with the motion inverted.
- Joystick axis 3 (clockwise / counterclockwise) controls device #2.
First, connect the joystick and the three additional T-Series devices. For installation instructions please view the T-JOY installation section of the manual. In the figure below we illustrate three T-LS devices connected in a daisy-chain to the T-JOY device:
Issue the Renumber Command #2 from the computer. After renumbering (less than 1 second) the joystick will become device #1, and the remaining devices will become devices #2, #3, and #4. Now commands may be issued to the joystick to set the desired behavior. Please note that the device # will need to change for each joystick axis in order to achieve the desired behavior. The command sequence is as follows:
- Device:1 Cmd:25 Data:1 - Set Axis # 1 to be the active axis.
- Device:1 Cmd:26 Data:3 - Set the active axis (#1) to control device #3.
- Device:1 Cmd:25 Data:2 - Set Axis # 2 to be the active axis. (Settings for each axis need to be set individually)
- Device:1 Cmd:26 Data:4 - Set active axis (#2) to control device #4.
- Device:1 Cmd:27 Data:-1 - Set active axis (#2) to be inverted (positive and negative directions switch).
- Device:1 Cmd:25 Data:3 - Set Axis # 3 to be the active axis.
- Device:1 Cmd:26 Data:2 - Set the active axis (#3) to control device #2.
Note: All commands are being sent to device #1 (joystick). This is because the 3 T-series devices will be controlled by the joystick. Setting axis number and directions must be done by changing the joystick settings, not the individual device settings.
Special Note: It is possible to have one axis control 2 or more devices. All of the devices on this axis will move together. Follow the steps below to set more than one device on a single axis:
- For each device you wish to control on one axis, set the device alias number with Command #48. Selecting an alias number much larger than the device numbers in use will help to differentiate between aliases and devices (Ex: 99). The alias number must be the same for each device you wish to control with a single axis.
- Issue the Set Active Axis Command #25 with command data equal to the axis number you wish to use.
- Issue the Set Axis Device Number Command #26 with command data equal to the alias number you selected.
