Activity LED #2 on bracket
The ACTIVITY LED #2 is dedicated to the activity of output ports
LED State | Meaning |
---|---|
Green | Normal mode - Flashing indicates activity on at least one output. |
Orange | Configuration mode |
Red | Error - The I/O module is not (yet) controlled by the frame grabber |
Off | The I/O module is not powered |
Status LED on board
The STATUS LED is dedicated to the activity of the I/O extension bus
LED State | Meaning |
---|---|
Solid green | Normal mode - No activity on the bus. |
Flashing green | Normal mode - Activity on the I/O extension bus. |
Flashing orange | Configuration mode - Activity on the I/O extension bus. |
Flashing red | Configuration mode - No activity on the I/O extension bus |
Off | The I/O module is not powered |

The 24 I/O ports are configurable by group. There are 10 groups:
□ | The groups #1 to #8 contain 2 single-ended I/O ports. |
□ | The groups #9 and #10 contain 4 single-ended I/O ports. |
Within a group, it is allowed to set all the I/O ports:
□ | for TTL input operation OR ... |
□ | for 5 V CMOS output operation. |
The configuration is saved into a non-volatile memory on the I/O module. The configuration is automatically restored after applying power.

The IOExtensionModule category of the Interface module provides a set of features to configure the 3617 I/O extension module:
□ | IOExtensionModuleConfiguration to enter/leave configuration mode |
□ | IOExtensionModuleLineSelector to select a MIO to configure |
□ | IOExtensionModuleLineFormat, IOExtensionModuleLineMode and IOExtensionModuleLineStatus to configure the selected MIO |
□ | IOExtensionModuleLineToRepair and IOExtensionModuleErrorCount to help troubleshoot an invalid current configuration. |
Configuration procedure
1. | Select an Interface module |
2. | Enter the configuration mode: set IOExtensionModuleConfiguration to Begin |
3. | Select the I/O line to configure: set IOExtensionModuleLineSelector to the desired value (MIO1 to MIO40) |
4. | Select the single-ended I/O line format |
□ | Set IOExtensionModuleLineFormat to TTL |
5. | Select the input or output I/O line mode: |
□ | For an input, set IOExtensionModuleLineMode to Input |
□ | For an output, set IOExtensionModuleLineMode to Output |
6. | Repeat from steps 3 for all I/O's to configure |
7. | Verify the validity of the configuration |
□ | Get the value of IOExtensionModuleErrorCount |
□ | If 0, the configuration is OK, proceed to next step |
□ | If greater than 0, the configuration is NOK, proceed to step 10 |
8. | Record the configuration |
□ | Set IOExtensionModuleConfiguration to Commit |
□ | The procedure is complete! |
9. | Repair the configuration |
□ | Get the value of IOExtensionModuleLineToRepair |
□ | Read I/O configuration capabilities and constraints to determine why the indicated MIO doesn’t satisfy the configuration constraints. |
□ | Adapt the configuration of one (or more) I/O's accordingly by proceeding from step 3 . |
