| Attempted connection to the TV551 turbo pump through Varian/Agilent's software on spica. Successful connection established, and we are able to read out al the readings associated with the pump (status, temperature, etc) through the software, which is actually pretty extensive and well organized. Was able to stop and restart the pump with no issues. Serial communications seem to be working fine, and the current serial settings (baud rate 9600, serial type RS232) all match what the Iolan was expecting with the previous connection test. Also notable: the code used for the previous (failed) connection test is written using 'Letter protocol', which is the older of the two communications protocols supported by these kinds of pumps. This rules out the pump being too old to accept the newer communication format as the issue, since it's the older format being used anyway. Will continue trouble shooting to determine why previous connection test failed. |
