- ART-M request data for a job.
- LMS responds with data for both eyes
- ART-M will upload SVAL, AVAL, KPRVA, KPRVM, PIND, GRPVA, GPRVM, _BLKDM, _BLKRD and _BLKCEHI. The data for the RIGHT eye is what was actually blocked; the data for the left eye is a mirror of what was received from the LMS.
- ART-M will request data for the same job a second time; this is used for the left eye blocking. Therefore, the data uploaded for the right eye must be re-sent to the blocker, but the left eye data should be that as calculated by the LMS
- ART-M will upload SVAL, AVAL, KPRVA, KPRVM, PIND, GPRVA, GPRVM, _BLKDM, _BLKRD, and _BLKCEHI with data for the LEFT eye; the right eye data is also present, and is a mirror of what was received from the LMS in step 4.
In Rx-Universe, the device session for the ART-M should be set up with 2.00 degrees of prism to be sent to the generator (with the remainder blocked), and a maximum blocker prism of 4.00. (Note that the generator prism is a guideline; the ART-M will calculate the actual amount of prism to be both blocked and generated). The checkbox indicating the device is an ART blocker must also be checked.
...
If the total amount of prism required for a job exceeds that allowed in the generator prism field + maximum blocker prism field (assuming both are >0), then an error is raised when the job is requested by the ART-M (rather than the error being raised when the job is requested by a generator as with other devices).
Settings on the blocker itself
The ART blocker has two connections to Rx-Universe - one to request job information, in which case it acts as a SBK device, and a second session to upload data - this second session needs to be an UPL session.
Settings for the generator interface
If you are running Rx-Universe version 7.35.00 or earlier, and using an ART-M, the blocker does not upload BLKD and RNGH information. If the lab uses ONLY ART blocking, you will need to configure the generator interface to set these values. Do this, on the generator configuration, VCA Over-rides tab, as follows:
Note this is NOT necessary for Rx-Universe version 7.36.00 and later.
