RS-232 to RS-485/422 Media converter Feature Highlights Maximum Communication Speed: 500Kbps Industrial Grade Temperature: -40~85°C ESD Protection (IEC 61000-4-2: ESD level 3 protection) External power not required (When RTS/DTR signal line is enabled) Compact size Hardware-based Auto Toggling RS422/RS485 mode selectable by external switch Built-in 120Ω termination resistors, selected by external switch 3kV isolation LED port power indicator Port Power over RS232 The RS-232 port of the SS100/SS100SiS is a DB9 female socket that can connect directly to the host PC, using the RTS/DTR lines to receive the power needed to run. Regardless of whether the signal is high, the can obtain enough power from the data line. SS100-SiS, the version with isolation, still requires an external power supply. When there are many devices connected to RS422 or RS485 signal lines, we recommend that external power supply is necessary. LED Port Power Indicator It is easy to let the SS100 test the device for you. Simply connect the SS100 to the device’s RS-232 port and set the RS485 Echo mode. If the power port LED indicator of PWR/Tx/RX lights up, then SS100 is receiving enough power and data communication is working properly. Application RS422/485-4 wire Wiring (Master-Slave System) The termination resistors should be enabled at the both ends of the cables; the master and the last salve. RS485-2 wire Wiring The termination resistors should be enabled at the both ends of the cables; the master and the last salve.
