We have an autosampler (G1313A) on our 1100 HPLC with tray chiller installed; however, there is not option in OpenLab to set the tray temperature. We are using OpenLab server 3.2.0. What are we missing?

You should be using the "close connection" button in the ribbon of the control panel on that instrument to disconnect as you suggest you have done. You should always do this before attempting to connect another workstation to your instrument.
I wish I could, but close connection does not seem to work anymore even after reboot of the OpenLab server. If anyone is able to make sense of the error message posted above, please let me know.
I was finally was able to connect with Lab Advisor. The Sample Thermostat shows up as a G1330B under the autosampler module.
Hi sassman,
After verifying that the thermostat is seen by the hardware are you able to configure it in the data system? Typically auto configuration should do this for you, but you can verify that it is enabled in the configuration options. This is also where, in later versions of the software, you can set the temperature to either be controlled by the method or to be an instrument parameter that does not change method to method. This is an example from a wellplate sampler so it has more options, but I believe a G1329x would still have the Thermostat option.
We opened the instrument configuration, and "thermostat installed" is checked. "Thermostat controlled by method" was not checked. We selected it, and press OK. Re-open configuration, and "thermostat controlled by method is still selected". Closed configuration and launch the instrument. There are no options to control sampler temperature. Go back to configuration, and now "thermostat controlled by method" is not checked again. So for some reason, launching the instrument causes that box to become unchecked.
We finally got it working. Turns out, it wasn't plugged in all the way! It was hard to diagnose because there is no power light on the front of the unit, and it is very difficult to see behind the instrument since it is backed up to a wall. We still cannot control it from the method, but at least we have manual control and that's enough for now. Thanks everyone (especially Howard) for your efforts!
