Description for the ISO35TEVM
This document describes the ISO1176T/35T/3086T Evaluation Module (EVM). It is used to evaluate the ISO1176T PROFIBUS Transceiver, the ISO35T RS-485 transceiver, or ISO3086T RS-485 Transceiver. Because the devices are similar transceivers, and the printed-circuit board is the same for all three EVMs, this manual can be used for all three devices.
The EVM can be used to evaluate the device parameters while acting as a guide for the board layout. The board alllows for the connection of 50 ohm coaxial cables via QuiteZone connectors. It also provides easy connection points for oscilloscope probes. Banana jacks are provided for the connection of a dc power supply. These features provide the designer with a tool for evaluation and the successful design of an end-product.
