Indicator Display Color Meaning
PWR Lit Green The communications power supply is ON.
Not lit The communications power supply is OFF.
COMM Lit Yellow Normal communications
Not lit A communications error has occurred or the Module is in standby status.
ERR Lit Red A communications error has occurred.
Not lit Normal communications or the Module is in standby status.
0to15 Lit Yellow The corresponding I/O signal is ON.
Not lit The corresponding I/O signal is OFF.
3DIP SWITCH SETTINGS
Pins 1 and 2 are reserved. The
default setting is always OFF.
Baud Rate Setting
Mode Pin 3 Setting
