Digital Interface -RJ45- Pin Out

[RandyChase]

Attached is the interface using standard CAT-5 cable or an RJ-45 connector.

NOTE- This is not a standard Ethernet. We just use a similar connector. Do not plug your network or computer into this port. Doing so will be very bad. As in smoke will come out of the unit.


Remote switch control is via the middle two pins. Pin 4 and pin 5. One is remote signal, the other is ground. Connecting these two pins together will be the same as pushing the button on the front panel. You can turn the unit on or off, start and stop recording, but using these two pins.

The next set of pins from the middle are pin 3 and pin 6. These drive the dual color LED (or can be used to drive two LEDs) the same as the LED on the front panel. Pin 6 drives the RED and pin 3 drives the GREEN. Both drive the ANODE of the LED which has the CATHODE connecting to GROUND (same as pin 4 or pin 1).

The next set of pins outward from the center is the RS-232 pins. Pin 2 is TRANSMIT and pin 7 is RECEIVE on the PDR.

Please do not use pin 8, this is for factory use only and should not be connected on your end to anything.

This may have been covered elsewhere, but I'm interested in using the RS-232 capabilities of the PDR100. I have a data system that can output to RS-232, and I'd like to use this to trigger recording of the PDR100. My question is what type of signal do I need to send to the PDR to trigger starting/stopping of recording?

[RandyChase]

Note we eventually added RS-232 control over the recorders

To control the recorder, means you want to control the recorder pin on the remote and pull it low momentarily for 40ms, that signals the CPU that there is a switch. Then apply logic. Note you can monitor the LED signal line status to get condition of the recorder also.

[JohnJL]

Do #4 and #5 need to be connected momentarily or for the duration of recording? I'm planning out my dash now and want to get the right switch...can I just use an on/off switch that is off in one position and on in the other?

[RandyC]

Our latest firmware will allow you to use an alternate switch. The standard setting on the PDR requires a momentary switch.

So you can go either way. But if you use the alternate switch where it is continually connected, you need to set that in the menu.

It also changes a few things. Power down by remote is disabled and is done via the keypad.

Thanks for the quick response Randy!

What are the current/voltage/other restrictions on the LED power #3 and #6? Any style LED?

THanks again

Could you please check this section of your description again:
"The next set of pins from the middle are pin 3 and pin 6. These drive the dual color LED (or can be used to drive two LEDs) the same as the LED on the front panel. Pin 6 drives the RED and pin 3 drives the GREEN. Both drive the ANODE of the LED which has the CATHODE connecting to GROUND (same as pin 4 or pin 1)."

I found the opposite to be true. The Orange striped wire wants the Cathode and the Green striped wire wants the Anode of the LED.

There is some confusion. The green striped wire is pin 1, which does indeed want to connect to the Cathode.

Okay, I just picked up a red/green LED at radioshack. It only has 2 leads. Power one way it's green, the other way it's red. Will this work or do I need two color leads and ground?

Russ,

This kind of led are not very brilliant, It's depend on your car but if there is a lot of sun it could be difficult to see if it's green or red !

Normaly it will work, but sorry I'm not sure. The PDR inboard led could be the same as yours.

If you look for a very small momentary swich, think that in an old PC case, you have it and also the leds.

Hope it's help you

I ended up using a separate red and green, as I also had those.

Hi, I have a situation where i have 2 recorders in a car, one records video out the front and the other records the occupants, is it possible to have one switch to control both recorders? i have had big problems with LAN-C in this situation when coupled to an extension so i no longer want to use the LAN-C (i need a long cable as the recorders are not close to the passenger compartment)
any help would be great

cheers

Mike

Hi Mike,

I had the same set-up for my car. A PDR for the front and a second one for the rear.
I built a single commande for the both using the RJ45 connection of the PDR.
It's worked without any problems.
Using an Ethernet wire for the RJ45, you have the choise for the longer.
Look at into this topic, you have all the images for the connection.

Hope it's help you

This looks to be a good bi-colr LED for this application. Any comments anyone?

Can this remote start/stop interface be used with a DM-10 module attached, or is a LAN-C controller needed? Does the DM-10 only communicate through pins #2 and #7 or are there other pins in use? Could lines 1,3,4,5, and 6 be tapped to make a remote start, or will bad things happen?

Thanks

[RandyChase]

The DM10 passes through the functionality of the RJ-45 interface (except the communication pins 2 and 7). So yes, it can be used. Or you can use the LAN-C.
