Cabling
Cable Types
There are many cable types. In a compact router system, cables differ primarily by connector type.
Miranda routers have BNC connectors for the most part.
Length limits are as follows:
• SD Belden 1694A, BNC, 350 m at 270 MB/s (1312 feet)
• HD Belden 1694A, BNC, 150 m at 1.485 GB/s (492 feet)
• 3Gig Belden 1694A, BNC, 100 m at 2.97 GB/s (328 feet)
• AVBelden 8281, BNC connectors, to 1000 feet.
• AABelden 8451, DB25 connectors (each supports 8 shielded twisted pairs), to 1000 feet. See
DB25 Connectors on page 71. Miranda’s WC0053 breakout cable can be useful with DB25
connectors.
• PortRJ-45 connectors, cable length to 100 m with high-quality cable. Port routers often connect
to machines (VTRs, for example) that have DE9 serial connectors. If that is your case, you will
have to fabricate a DE9-to-RJ45 cable. (Miranda’s BP-PORT-64 breakout panel can be of some
use here.) See
RJ-45 Connectors on page 71.
• EthernetRJ-45 connectors, cable length to 100 m with CAT5 or CAT6 cable. Beyond 100 m, you
will probably get some packet loss or degradation in speed.
Connectors
Serial Connector
The automation connector for all CR Series Compact Routers has this pinout:
The connector is RS-485, but can be used as RS-422. Most of the compact routers allow RS-485
multi-drop now and eventually all will support it.
Customers who want to operate the router through an automation system may contact Miranda
technical support for information.

Note On remote panel modules, the serial port is not active and will be removed
from future versions. Automation cannot use Remote Panel Modules.
