*RS232 to RS485/RS42 convertor is specifically designed for extending the distance of RS232 and RS485/RS422 bus transmission. It owns a number of independent innovation technology, which including built in data anti-collision; charger and LED indicator light; TVS momentary voltage suppression. To adapt the numerical bus of RS485/RS422, there are many terminal, DB9, RJ45 interface which can satisfied the various wiring modal. The multidirectional bus can contact well and use expediently. The sand blasted aluminum shell can shield of foreign interference effectively and has great heat dissipation.
