The NI USB to mini-USB interface cable. This cable is necessary to connect the 16-bit CTI 5-BNC box to your computer. The USB-connector end plugs into a USB hub, or a USB port, and connects to the computer. The mini-USB connector end connects to the 16-bit CTI 5-BNC box. The cable is typically 3′ in length.

12″ RG-58 M-M BNC patch cable
This cable is necessary to use internal trigger option, and its use is described in the separate 24-bit analog interface document. Chesapeake supplies one with each NI USB-4431 unit sold. It has M-M type connectors (male ends).
F-M-F BNC tee connector
This Tee is necessary to use internal trigger option, and its use is described in the separate 24-bit analog interface document. Chesapeake supplies one with each NI USB-4431 unit sold. It has F-F type (female ends) connectors available after plugging it into AI 0, so that you can connect two things:
(1) The BNC patch cable connects it, so that AI 0 and AO 0 are connected, and the internal trigger you generate on AO 0 is received on AI 1.
(2) On the free F end of the Tee, you will probably connect your own BNC patch cable to your sonar equipment, so that the “internal” trigger drives the ping rate on your sonar equipment.
User-Supplied Equipment – Accessory Cables
Chesapeake Technology, Inc. does not sell BNC cables, other than the 12″ cable supplied with each NI USB-4431 unit. You must supply your own BNC connector cables to link the analog interface box data lines(s) and trigger, to your own equipment. Please purchase these cables elsewhere, as needed.
