DS9097U-E25开发板套件编程器的配件规格书PDF中文资料

DESCRIPTION

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 adapters RJ-11 port. The DB-9 version reads and writes any non-EPROM 1-Wire device. To write to EPROM devices the DB-25 version with external power supply is required.

FEATURES

• True-ground interface to an RS232 COM Port for reading and writing 1-Wire devices

• Works with bipolar as well as unipolar logic signals

• Compatible to COM ports of (±)5V to (±)12V (DB-9 version only) or (±)6V to (±)12V (DB-25 version)

• Supports reading and writing at regular and Overdrive speeds

• Provides strong pull-up to 5V for Tempera ture-, Crypto- and EEPROM 1-Wire devices

• Programs 1-Wire EPROM devices (DB-25 version with external 12V power supply only)

• Communicates at data rates of 9.6 (default), 19.2, 57.6 and 115.2 kbits/s

• Standard DB-9 or DB-25 female connector and 6-lead RJ-11 connector for easy attach ment of standard 1-Wire cables and probes

• Includes DS2502 identification chip (DS9097U-009 only)
