NavCom NCT-2030M Rev.C - Manual (Page 22)

NCT-2030M User Guide - Rev. C
- 50 Ohm, TTL level.
- Pulse width, default 100mS, range 10 – 999mS
- Pulse delay, default 0mS, range 0 – 999mS.
- Rising or Falling Edge Synchronization.
Connecting the 1 PPS output requires a cable with a BNC
male connector, NavCom P/N 94-310050-3003 0.9m (3ft)
long, BNC male to BNC male cable can be obtained by
contacting NavCom at [email protected].
CAN Bus/Event
The NCT-2030M also employs a balanced (differential) 2-
wire
CAN Bus technology interface, ISO11898 -24V
compliant. The CAN interface uses an asynchronous
transmission scheme employing serial binary interchange
and is widely used in the automotive industry. The data rate
is defined as 250K
bps maximum with Termination resistors
used at each end of the cable. This port/connector is shared
with the
Even t Input.
‡
As CAN Bus specifications are diverse, drivers for the existing
hardware must be tailored to the specific manufacturer’s
equipment being interfaced to. For further information, e-
mail NavCom Customer Support at

Event
The NCT-2030M also can utilize an event input pulse to
synchronize any external incident that requires precise
GPS
time tagging, such as aerial photography. In this case, the
action of a camera’s aperture would output a pulse to the
Event port and have the receiver output position and time
information relative to when the photograph was taken.
