Make sure you are using RJ12 and not RJ11 ends. The difference between RJ12 have 6pinout and 6contactor while RJ11 have only 4pinout and 4contactor please don't be confused RJ11’s are physically the same size as RJ12’s but will not work unless you are a Techie nerd geek.
pin 1 white / orange (GPS sync)
pin 2 white / green (Serial Tx 9600)
pin 3 white / blue (Serial Rx 9600)
ping 4 green (Default Jumper)
pin 5 blue (Audio /GPS Power sync)
pin 6 orange (Ground)
This override plug resets the LAN 1 IP address to 169.254.1.1. The plug allows the operator to access the module through the default configuration without changing the configuration. The operator can then view and reset any non-default values.
Acquiring the Override Plug
To fabricate an override plug:
1. Install an RJ12 6-pin connector onto a 6-inch length of CAT 5 cable.
2. Pin out all 6-pins.
3. Short (solder or twist together) Pins 4 and 6 on the other end. Do not connect any other wires to anything. The result should be as follows:
Pin 1 → white / orange ← Pin 1
Pin 2 → white / green ← Pin 2
Pin 3 → white / blue ← Pin 3
Pin 4 → green ← Pin 6
Pin 5 → blue ← Pin 5
Pin 6 → orange← Pin 4
Here's how you should number your RJ12 6pin socket.
Using the Override Plug
The operator can regain access to the module as follows:
1. Insert override plug into the RJ-12 GPS sync port of the module.
2. Apply power to the module through the Ethernet cable.
RESULT: The module reboots with the default IP address of 169.254.1.1, password fields blank, and all other configuration values as previously set.
3. Set passwords as desired.
4. Change configuration values if desired.
5. Save the settings.
6. Remove the override plug.
7. Power cycle the module.
