Delta DVP04DA-S2 User Manual

※ DVP04DA-S2 CR#32 communication format settings: for modules with firmware V4.14 or previous versions, b11~b8 data format
selection is not available. For ASCII mode, the format is fixed to 7, E, 1 (H’00XX) and for RTU mode, the format is fixed to 8, E, 1
(H’C0xx/H’80xx). For modules with firmware V4.15 or later, refer to the following table for setups. Note that the original code
H’C0XX/H’80XX will be seen as RTU, 8, E, 1 for modules with firmware V4.15 or later.
