CBA V Connections
(See Diagram on inside front cover)
USB Port
This is the connection to a PC for power and data. Make sure the PC is set to
never power down the USB port, so tests are not interrupted.
Accessory Port
This port is for future CBA modules or for the stand-alone temperature probe.
If using the remote voltage sense cable, it includes the temperature probe. Do
not use the stand-alone probe if using the remote sensing cable. With the
standard software, the temperature probe is used to abort a test if the battery
gets too hot. With Extended software the temperature can be graphed with the
voltage on the screen. Notice from the above diagram the two pins that need to
be used for the stand-alone probe
Remote Sense
This is an optional cable to separately detect the battery voltage. When running
a high current discharge test, there is a resistance across the cable. That
means the voltage at the battery is not the same as the voltage at the CBA. The
remote sense cable will allow the CBA to read the actual battery voltage. This
is important for the exact test termination time. The remote sense cable also
has a temperature sensor that can be attached to the outside of the battery to
terminate a test in case of over heat. The Extended software also allows for
charting the temperature.

Fuse blown. This can also happen if the remote sense cable is con-
nected to the battery, but the primary battery cable is not connected.

Internal self test error
Off
No power to CBA (check USB cable and port)
Fuse
To protect the CBA, use the smallest fuse necessary. This is a standard ATC
automotive fuse. A fuse puller was included with the CBA.
Battery Connector
The connector is a 45 amp Anderson Powerpole connector. A pigtail adaptor is
included with the CBA to help interfacing to a battery. The West Mountain Radio
website has numerous pre-made cables to go from this connector to other connector
types. This includes a laptop battery connector and adaptors for cylindrial cells. For
odd sized batteries, consider making an adaptor from an old charger.
