Everything is wireless these days. So why not pumps? I have a pair of wireless RS-232 adapters here which I have spent some time testing. In the beginning with a single pump connected every thing seems to set up and connect. But once you have say 6 pumps and hit the Run button – the delay with the RS232 over wireless starts causing problems.
Commands sent to pumps don’t arrive at the time intended and neither do the replies. It’s like you and a friend taking a series of questions and answers and randomly shouting them across a paddock at each other. – If you have more than one pump, then think of more than one friend.
It can work – but it’s not reliable. There are some communications settings you can tune in SyringePumpPro designed to help make this work. Contact me and I will help you with those settings.
One pump seems possible, but I don’t want to encourage you to rush out and use these things.
I did have a customer attempt to wireless-ly connect with one of these Wireless RS232 devices. Her pump was in a sealed glove box that was filled with nitrogen – to stop the experiment bursting into flames. In the end the wireless connection sort of worked – but wasn’t considered reliable enough considering the possible fire danger caused by unpredictable pump operations, generating the need to constantly open and close the glove box.
Solution – a rubber gasket and a wired trapped under the closed glove box door. Reliable pump operations and safe operator.
