Review: Useless - wrong pin-out - Completely pointless - they use non-standard (wrong) 9-way pin-out. This is only stated if you find the manual on the manufacturer web-site here: http://sgcdn.startech.com/005329/media/sets/DB92422_manual/DB92422_Manual.pdf They use pins 1-5 of the 9-way D, whereas most common RS422 pin-out conventions use pins 1,2,3,7,8.

nella descrizione sembra essere un convertitore da 485 a 232 invece è semplicemente una morsettiera. Non c'e' nessuna documentazione assente
