MCBH-6-FS pinout (RS-232) - RBRconcerto³, RBRmaestro³
The RBRconcerto3 variants with an elongated body and RBRmaestro3 instruments have MCBH-6-FS connectors with an serial pinout. This connector is intended for RBR sensors with an RS-232 output.
RBR properly installs all sensors included with your instruments. The MCBH-6-FS serial pinout will only be needed when an RBR sensor is shipped separately. If a spare connector may be required, it must be wired/activated at the time of purchase.
