All RBR loggers and recorders are supplied with a USB-C data cable that is used for downloading the data from the internal port on the RBR logger to a PC or a Mac. Sometimes data and power connections are required on the external part of the logger to allow for longer deployments or real time data access.
RBR recognizes that users may not want to pay extra for features that aren’t required. Therefore we offer the choice of external data and/or power connectors as an optional extra at the time of initial instrument manufacture. MCBH-6MP bulkhead plugs are used for all external data and power connections.
RS-232 and RS-485
Patch cables are intended for connections between an instrument and a computer. Underwater extension cables may be used for serial output instrument to increase the distance between computer and instrument. RS-232 can be used up to 50m (longer with lower baud rates). RS-485 is the long-distance choice.
Interconnect cables may be used for RS-232 and power, or general analogue signals, typically between two underwater devices.

For our legacy products, Impulse IE55(w) wet-pluggable are usually used for Single & Twin channel loggers and the XR series. Impulse MCBH are used for the XRX range. A Serial-USB adapter is required for legacy products.
Older RBR instruments typically use RS-232 protocol for data download. Since many of the latest computers are no longer equipped for RS-232 input, a USB adapter is necessary. There are many types on the market and some function better than others. We can supply one that has been tested and proven to work with our instruments.
Contact us to discuss your connector requirements at the time of order placement. In some cases, it may be possible to retro-fit connectors.
Contact RBR for delivery time on custom order cables. Note: there is a practical performance limit on the length of a cable used for RS-232 serial transmission. Typically, RS-485 transmission should be considered for cable lengths in excess of 50m at data rates of 19.2Kbaud and higher.
