1-Wire COM Port Adapter DB-25
The DS9097U is a sophisticated RS232 to 1-Wire adapter, which performs RS232 level conversion and actively generates the 1-Wire communication signals. Together with an adequate TMEX software driver, it enables an IBM-compatible PC to directly communicate with any 1-Wire device connected to the adapter's RJ-11 port. The DS9097U-E25 reads and writes EPROM 1-Wire devices. To write to EPROM devices, an external power supply is required.

Notes
The external supply for the DS9097U-E25 must provide well-regulated 12V @ 10mA minimum, center = GND, outer ring = V+ (Newark Electronics Stock No. 84F2081, Allied Electronics Stock No. 928-9895, Stancor Model STA-300R, or equivalent).

The color of the DS9097U-E25 plastic case may vary.
