CarNetix PSU-PC12 V1.1 Installation Manual
3.0 Using the Pulse Start Feature
The PSU-PC12 includes a new feature that allows you to remotely start and stop the PSU.
This feature is called “Pulse Start”. This feature would normally be used in conjunction
with a wireless device such as a car alarm with auxiliary inputs/outputs or a WiFi device
with Wake-On-LAN (WOL) features.
3.1 Pulse Start Connections
The Pulse Start input can either be an externally applied voltage (ie +5v or +12V) pulse,
or a momentary relay contact closure. The externally applied voltage pulse is connected
to Pin 1 of J1 using the Blue wire. The momentary relay contact closure is connected to
Pins 1&2 of JP1 (see Section 2.2 for location). You can use either or both of these
connections to start/stop the PSU.
3.2 Pulse Start Operation
3.2.1 What is a pulse?
Voltage Pulse on Pin 1 of J1
When connecting to Pin 1 of J2, the “pulse” must be a voltage that transitions from 0V to
+V,
and then transitions back to 0V . The SSC will wait (hang) if the voltage stays high
without going back to 0V after the initial transition from 0V to +V.
The value of the +V can be any voltage from approxi2V to +20V. Typical
voltages are +5V or +12V. The value of 0V must be below +.2V or open circuit (ie you
could drive this input with a relay that momentarily connects to a +12V source and then
provides an open circuit).
The current required to drive this input is very low (milliamps).
Contact Closure Pulse on Pins 1&2 of JP1
When connecting to Pins 1&2 of JP1, the “pulse” must be a low resistance metallic
contact closure (ie relay) that transitions from OPEN to CLOSED,
and then back to
OPEN . The SSC will wait (hang) if the contact closure remains CLOSED after the initial
transition from OPEN to CLOSED.
The current passing through this relay is very small (milliamps) so a low power relay can
be used.
Pulse Width
The pulse width can be any value from a minimum of approximately 100mSec to several
seconds. As mentioned above, if the pulse is very long the SSC will wait for the transition
back to the normal state before continuing.
