The 17233 is a version of the SC32B intended for OEMs. It does not have a label, so the OEM can attach their own branding. This optically isolated RS-232 interface is used to connect a PC to the data logger's CS I/O port via an SC12 or SC12R-6 cable. Optical isolation protects against ground loop, normal static discharge, and noise by isolating the computer's electrical system from the data logger's electrical system. Baud rates up to 115 kbps are supported.
