5.2.
Buzzer
There is a built-in buzzer that can be used for audible notifications. The buzzer is software
controllable with configurable volume and frequency.
For buzzer location see Figure 3. See chapter 4.4 for buzzer notification events. Refer to the
CCpilot
VS 12” Software guide
for details about controlling the buzzer from user applications.
5.3.
Analog video input
There is a video input for connecting an analog video source such as a rear-view camera. Displaying
of analog video is handled in hardware with minimum impact on CPU load.
The analog video input supports a wide range of commonly used composite video formats (both
PAL and NTSC).
See
c
hapter 7.1 for details.
For proper video performance and to ensure electromagnetic compatibility, 75 Ω coaxial cable shall
be used for connecting the video source. Preferably use coaxial cables of type M17/94-RG179. Refer
to chapter 3.3.1 for recommendations about connecting video coaxial cable.
It is important to supply the analog video source with a stable well-filtered supply voltage. Note
that video input grounds are internally connected with main supply ground. Precautions should be
made to avoid ground-loops between the video source and main supply ground which could affect
video quality. One way of avoiding ground-loop is to add video isolators or use a video source with
galvanic isolation between supply and signal ground.
5.4.
CAN
CCpilot VS 12”
has four CAN ports, supporting ISO 11898 CAN 2.0B protocol (29-bit extended
identifier) and bit rates up to 1 Mbps.
CCpilot VS 12"
is compliant with AEF ISO 11783.
Note that Internal EMI filters on CAN High/Low signals have a capacitance of 100 pF (typ) which
deviates from the ISO 11898 standard and implies some limitations on the CAN bus topology
(maximum bus length, number of CAN nodes etc.) when running at high bit-rates, i.e. above 250
kbps.
The ports feature highly protected CAN transceivers which are tolerant for bus short-circuits to
main supply voltage and ground.
CAN shield connections are according to J1939-11 with capacitive coupling to ground. There is no
device-internal CAN bus termination, therefore bus termination must be applied externally.
5.5.
Ethernet
CCpilot VS 12”
has an Ethernet interface supporting 10BASE-T/100-BASE-TX/1000-BASE-T and
Auto-MDIX.
The Ethernet interface is galvanic isolated with 1.0 kV
AC
insulation voltage.
Shielded cables shall be used to ensure reliable communication and electromagnetic compliance.
As with all Ethernet enabled devices, connecting the device to a public network environment may
impose an IT security threat.
