Sell Industrial port-powered isolation RS-232/485 converter China (Mainland)
SW485WA is a converter that change RS232 signal to RS485 signal or
positive. It is no-power needed, It can supply optic-electrical
isolation only obtain power from RS-232 port, It is high delicacy,
function stabilization and so on. adopt DB9 pin currency serial
interface.
