configuration switches and jumpers set to their default positions. To start using
the evaluation kit, follow these steps:
DS90CR485/486 Evaluation Kit User Manual
Rev. 1.01
1) Connect one end of the D26-1 MDR cable to the transmitter output
2) Jumpers and switches have been configured at the factory for default
3) Connect the appropriate IDC cable from the incoming data and clock to
4) Power and ground for the board must be supplied externally through J13
connector (J4) and the other end to the receiver input connector (J5). If a
longer cable is desired, please contact 3M for more information (3M
contacts are included at the end of this document). Cables from other
manufacturers (e.g. Amphenol SKEWCLEAR) can be used and/or the
board can be modified to interface to custom cable or backplane
interconnect.
