NO RATINGS
"In the absence of pushbuttons on the LCP, we had to carry a handheld version of the TWC transmistter out to a particular inductive loop in order to enter a request. Considering the inconvenience of having to walk out to the yard with the handheld, we decided to add real control capability to the panel." I don't doubt this is the case, but I don't understand why suppliers do things like this. Seems like it ruins the good will between the supplier and the customer.

Galen, you seem to have found a good solution to your problem.  The only question I have in these instances is that of certification.  Is there an issue with that when field modifications are made to the control system?
