TEXAS INSTRUMENTS SN65HVD96EVM 评估模块, 用于 SN65HVD96
The is an evaluation module for SN65HVD96 specifically designed to meet the requirements for a transceiver which operates with no errors if the twisted-pair signal wires are connected normally or reversed. This allows for error free operation in applications where the signal wires may become inadvertently reversed during installation or maintenance. This feature is corrected internally so no intervention from the controller or operator is required. The SN65HVD96 complies with the requirements of ANSI/A-4963, electrical characteristics of reversible balanced voltage digital interface circuits. Similar to RS 485, these transceivers can be used for point-to-point, multi-drop, or multi-point networks. Sympol devices are not backwards compatible with, but are an upgrade to, existing RS 485 networks. The pin out is identical to the industry-standard SN75176 transceiver, allowing direct upgrade from RS 485 to SymPol.
