Using SmartLinc Probes with HomeVision
The HomeVision (and HomeVision-Pro) input ports can interface with the various sensor probes made by SmartLinc.
Setup
Requires: A cable with a 3.5mm stereo jack on one end and wires on the other end.
Connections: Plug the probe's 3.5mm plug into the cable's jack. Connect the
cable's bare wires into HomeVision's port B or C terminal block as follows:
 | Red wire (the plug's tip) to the 5V position. |
| Ground wire (the plug's body) to the ground position. |
| Gray wire (the plug's center ring) to one of the eight input positions. NOTE: If the wire colors don't match these descriptions, use an ohmmeter to determine which wires connect to the terminal block. One HomeVision owner recently reported that his SmarLinc video probe used the following wiring scheme: |
| White wire (the plug's tip) to the 5V position. |
| Ground wire (the plug's body) to the ground position. |
| Red wire (the plug's center ring) to one of the eight input positions. |
Notes
| The TV Sniffer Probe usually has a several second delay after the TV goes off
before the probe's output changes. The probe is usually faster on HomeVision port B than
on port C. If you're using the Multifunction Expansion Board, port 1 will be faster than
ports 2 or 3. | ||||||
| If you choose to cut the probe's plug off and wire it directly to HomeVision, you
will have to identify which wire is which. On one probe we tested, the wires were as
follows:
We found these wires to be difficult to work with. We had to solder another short wire onto each wire before we got electrical continuity. Therefore, we recommend using a separate cable with a jack. |
