Note 1: When using an RS485 bus of substantial length, do not forget to use 120 Ohm termination resistors on both ends of the bus.

  • Each Bus Probe has a detachable terminal block with four terminals: ground (GND), power (+V), as well as RS485+ and RS485- lines of the RS485 signal pair.

  • Communications parameters of the RS485 port are 38400-8-N-1.

  • When using an RS485 bus of substantial length, do not forget to add 120 Ohm termination resistors on both ends of the bus.

  • The MD button* has two uses:

  • Status LEDs display a number of device states and errors.

  • Mounting holes can be used to attach Probes to flat surfaces.

* Each Bus Probe comes with a metal pin that makes pushing and holding down the MD button easier.
