Isolation performance: 1000V isolation9. Power consumption: 1.5W DC9~24V10. Maximum transmission distance: 1200m (4000ft) 19.2kbps11. Status indication: on-board transceiver indicator display in real time12. Working temperature: -20 ° C ~ 65 ° C13. Working humidity: 25%~85% (non-condensing)operating steps1. Connect the working power supplyAfter the positive and negative poles of the power supply are connected, the POWER lamp should be in the green steady state.Working power requirements: voltage in the range of 9 to 24V, current greater than 0.75A2.1 connection signal line(RS485 to4 portRS485)Connect the RS485 signal line of the main port and the slave port. If there is no communication, the module should be all red light off and the green light is always on.2.2 Connect the signal line(RS232to4 portRS485)Connect the mast port RS232 and the slave port RS485signal line. If there is no communication, the module's red lightshould be completely off and the green light is always on.3. Host and slave communicationWhen the corresponding channel has data input, the red light flashes.When the slave port fails, the red light is always on and the power light isflashing.
