Ninco Digital Pit Lane connection to PC USB
Needed Material:
i)
ND 108 Power Base (See document: ConexionCentralND108aPC_en.doc).
ii)
Ninco Digital Multilane Sensor (Ref. 40206).
iii)
RichG Pit Lane to PC USB cable (TTL to USB).
iv)
PCLC RMS software (Tested with PCLC, RMS Race Management System).

108 Pit Lane system managed by PCLC (RMS).
Development:
1) We need to disassemble Ninco Digital’s multilane sensor track (ref. 40206).

2) Cut the sensor track, to have the desired detection track:

3) Now we’ve both sections needed for the Pit In / Pit Out detection. One of those
semi-tracks can’t be connected directly because the track clips will not match, so we
should “repair” it to match or we also could use the original Pit Lane track from ND
Pit Lane set: ref. 40203.

4) The connections from the track to the sensor board is as follows::
a. Signal cables to the sensor:

Fig1

Fig1
On the Tx OUT connector we will see that we already have a cable attached from the
original jack cable. This wire remains as it is.
On the GND connector we will se that it’s free, and we need to use the second wire “not
used” on the original jack cable (Fig1).

Now we have TX OUT and GND connected to the original jack cable.

b. Powering up the sensor:

We need to power up again the sensor, for that, we’ve GND y VCC connectors. We
only need to remind and follow the polarity when welding again the cables on it’s place.
So, take a look when desoldering to have everything clear (polarity) when soldering
again.
c. Pit In / Pit Out detection zones connection (S1 and S2 from the multilane
sensor).

The S2 connector of the multilane sensor will be connected to the Pit Lane entrance
dead strip (in our case, the dead strip of the ND original Pit Lane Set).
The S1 connector of the multilane sensor will be connected to the Pit Lane exit dead
strip (in our case, the dead strip of the ND multilane sensor Set).

5) Final Assemble:

6) PitLane to PC USB RichG cable connection:
a. We will use RichG socket cable version (jack socket to USB).

b. Connect the jack:

c. Connection Ready:

7) Configure your COM port to:
Bits per Second: 1200
Data Bits: 7
Parity: None
Stop Bits: 1
Flux Control: None

8) PCLC configuration. On the 108 interface Windows, select the port created by the
Pit In / Pit Out sensor. On the race, if a car crosses the Pit In sensor and the system
says Pit Out and when exiting the Pit it says Pit In, simply select the option “Invert
In/Out”.

Other combinations of this system:
Like always there exist variations of this system, improvements and adaptations for
each user and situation. On the next lines we will take a look into them:
A) On the point 3), there can be used both sensor tracks, the original Pit Lane Set
tracks or any other track containing a free dead strip. Also tracks reworked for
that purpose, we Only need a dead strip isolated from the rest of rails..
B) On the point 4.a) we can use the original jack cable or a cable omitting this jack
connection with 2 wires and directly USB on then other side. RichG offers us 2
options:
a. ND Pit Lane to PC USB cable with jack socket, 1m, 2m, 3m, 4m o
5meters.
b. ND Pit Lane to PC USB cable with 2 wires, 1m, 2m, 3m, 4m o 5meters.

C) At point 4.b) we could use an external power supply of 14Vdc to avoid track
problems, etc. For that purpose, we could use a regular ND trafo, any other
external power supply or direct power lines from the PB S/F.
D) At point 5 we can choose any other sensor location on the track itself, or
completely out of it avoiding possible track signal interferences, etc.
E) At point 6.b) this connection would be eliminated in case of using the cable
mentioned at B.b), but this could cut our flexibility on semi-permanent
circuits/tracks.

System Ready:

The End.
