User manual: ASTRID serial device
Status:
The ASTRID serial device was original ment as a test device, but is currently being used permanent to access parameters on the old control system from ConSys. Most parameters has now been moved to the new control system, but the DAF controlled parameters are still on the old system. The stability of the serial connection is unfortunatly quite unreliable, but the device try to catch most communication errors.

Overview:
The ASTRID serial device is a temporal/test device used to access parameters on the old control system. The device acts like a console seen from the old control system. The communication operates serial RS422 line at 9600 baud. A console on the old system can have up to 32 active parameters registered. If more than 32 parameters are registered to the ASTRID serial device, only the first 32 is updated and can be controlled. ired value.

Parameter name | Data Type | Interpretation | Mode | Comment |
| 0 | free | Number of free parameters | Word | . | Read | Return number of free parameters on the device. 0-31. |
| 1 | Abort | Abort CCP | Bit | . | Write | Send and CCP abort to ASTRID. The connection restarted when Reconnect is called - or when the device internally does an device cleaning (this may happen when a client connects with new parameters). |
| 2 | Reconnect | Reconnect to ASTRID | Bit | Write | Start by sending Start Cpp. Thereafter an X-ON,Exit CPP, Start CPP to. Finish with reconnect of registered parameters. | |
| 3 | noCon | Number of automatic reconnets | Word | Read | Return the number of times the device has done an automatic reconnect to ASTRID. This is done |
G64 parameters:
The device emulates a G64 device, and all parameters are accessed like they where in a G64 crate. The addressing and data types is the as for the G64 device - excect that the softcode field is used instead of the G64 subadressing fields.
