Notes:
1. The initially released chassis is Tx only and does not support 1:1 operation. It does not support
1:N operation and is not upgradeable. This chassis is also not upgradeable to Rx only or duplex
operation.
2. The Rev. A and later chassis is required for 1:1 or 1:N operation. It supports Tx Only, Rx
Only, and Duplex operation
The European EMC Directive (EN55022, EN50082-1) requires using properly shielded cables for
DATA I/O. These cables are double-shielded from end-to-end, ensuring a continuous ground shield.
