I powered it up at about 10V, and it works.
The power led glows, and if I issue a reset the T/R led blink for about 2 secs then goes off.
I tried some quick example to test if it is able to transmit something, and it blinks when it should be.
Only concern is power consumption and smell.
There is a transformer inside (I don't know why, I should suppose it is used to regenerate the rs232 voltages), that is getting too hot. I tried to lower the DC level until the interface is not able to succesfully initialize (about 5V), but it is still way too warm. There is a smell of old thing powered up after being stored *many years*.
I don't have a multimeter I could trust about current reading, but it is in the .9A consumption range, too much I think.
Maybe this one is the only one interface that does not "support" the dc trick.
Tomorrow I will try to get a transformer with 8V AC output.
P.S: the power supply I am using actually is rated 30A peak, it deserves caution.
