Greetings guys; I hope everyone has arrived back home without incidents involving bent sheet metal or worse.
1. someone said the 7i92H needs its own dedicated ethernet port, presumably because udp patckets are not subject to any attempts at error correction resends if other traffic walks on a udp packet. So that means I'd need to find an Orange Pi with 2 ethernet sockets so two independant paths/addresses can be setup. None of these low power use cards have that, none that I've found have a 2nd port. Is this a case of just waiting till it does happen? Space considerations for the rj45 socket says it not going to be at all likely. Comments anybody? 2. In playing with this phony vfd today after I got everything bolted down again, I find the lack of docs a good sized problem. My test code loop to exercise it has a direct reversal in it at one point and I'd like to decelerate it to about 25 hertz in 5 to 7.5 seconds from whatever speed its turning, switching on the dc brakes at that point to bring it to a smooth halt. Then accelerate smoothly in the other direction. It acts like that is what its doing for a straight stop from either direction. and the booklet says in can go directly from one to the other. However, in trying to speed up the changes, if I just switch directions, it gets down to about 25 hz, then jumps off the table about an inch, and is then running the other direction at the set speed even if the set speed is 120 hz! No accelleration softening ramp at all. This controller has about 8 registers that can be set for various speeds where they are in effect, but zero discussion about what they effect in this little booklet. So how to go about optimizing those settings? If anyone has any wisdom to share, I'd sure appreciate it. Thanks everybody.
