The CFA-RS232 Level Translator is a small printed circuit assembly that can be mounted on a compatible Crystalfontz Intelligent LCD Module. Less than one inch high and a little over one inch wide, the CFA-RS232 is an easy way to change to "full swing" RS232 serial interface on compatible modules that have "logic level", inverted serial interface.
For detailed CFA-RS232 specifications and connection information, see the datasheet under the Datasheets & Files tab on this website page. Compatible Crystalfontz LCD Modules:CFA635 (all models). CFA735 (all models), CFA835 (all models)
