DB9 connectors
RBR smart sensors use RS-232 patch cables (see Fig. 13) for connecting to your computer and power supplies. Depending on the ordered configuration, your patch cable may have an embedded converter and either a USB connector or a DB9-F connector. Refer to the RBR Cable Guide for available options. |
