The external power supply
- ZT - 244 is a RS - 232 / RS - 485 / RS - 485 serial fiber MODEM, USES the industry standard design, the wall design support - rail DIN standards guide installation, installation is simple. At present, many users are using the RS - 232 / RS - 485 / RS - 485 serial fiber MODEM to solve the electromagnetic interference problem in engineering, and delay the RS - 232 / RS - 485 / RS - 485 serial port transmission distance to several kilometers or even dozens of kilometers. ZT - 244 is able to provide the user with the RS - 232 / RS - 485 / RS - 485 serial port end-to-end transparent transmission, because of using optical fiber transmission, in the optical fiber transmission signal light, there is no electrical conductivity, and thus has a strong anti-interference ability, will not be affected by high voltage and lightning.
