Description
DS512 Combined Alarm/Tracking System - AUX Module
'Allows timed control of Vehicle Convenience Features using Smartphone'
The DS512 AUX is an additional module for controlling vehicle accessories through the Digital Systems DS 512 Smartphone App. After wiring and selection of desired settings, the DS512 Aux Module can be remotely controlled, for example, independent heater (Webeasto, etc), heated seats, lights, etc. You can set functions such as "Coming Home" and "Leaving home" that enable Automatic lights of the vehicle for a short time when unlocking or locking the vehicle with the remote control. The module can also be used as an additional input for monitoring the status of another electrical circuit or device in a vehicle. The screen Icon on the App can be changed to suit the application required and timings required for time outputs.
DS 512 AUX function module:
- ON/OFF control of electrical devices in the vehicle with additional output
- Adjustment functions "Coming home" or "Leaving Home" lights system or both
- Ability to monitor status of electrical devices in the vehicle
Overview of Aux Module and Fuctionality
DS512 may be equipped with programmable AUX module for additional output / channel.
The main purpose of this module is to enable and disable any object using SMS commands or TytanGPS mobile app. An object can be, for example: auxiliary heater, lights or open the vehicle trunk release. Additional AUX channel can be switched on permanently or for a specified period of time (up to 999 minutes). If the additional channel operation is programmed, the DS512 transmits ‘AUX
output status’ in each SMS with the status of the device. The module has several programmable configuration modes dedicated to specific applications - auxiliary heater control, trunk release, lights control for coming home and leaving home functions, etc.
AUX Module Inputs/Outputs
AUX module must be connected to the RF module socket on wire harness, that is to 3 pole white connector. If there is a need to use both modules: AUX and RF at the same time – then the RF module must be connected to the socket on AUX module.
AUX module has one OC type output, coming on black wire in 2 pole connector. White wire is internally connected to the power supply. The connector fits the NO/NC relay included in AUX module set.
AUX module has two inputs, they are used in mode 2 and 7 to control the switch state of device. White-yellow input senses +12V, brown-yellow senses GND (ground).
Mode 1 – input switched constantly or for programmed time
Basic operating mode for switching on and off any device, for example to control auxiliary heater without built in timer or controller.
After receiving a switch on command the relay is switched on, accordingly permanently or for certain time (from 1 second to 999 minutes).
The relay is being switched off either when the time goes out of a switch off command is received by DS512.
In this operation mode ‘State of additional AUX output’ is status information sent by DS512 responds to relay switch on or switch off state. White-yellow and brown-yellow inputs are ignored.
Mode 2 – control or auxiliary heater switch
Mode for devices that turns on and off with consecutive presses of single switch, that is by pulses on single wire. Mode designed to control auxiliary heaters, either OEM heaters of aftermarket heaters (like Webasto or Eberspaecher), equipped with internal timers/controllers or control switches with indicator lamp.
AUX module relay circuit must be connected parallel to the auxiliary heater control switch.
To make the mode operational a proper signal (+12V or ground) must appear during activation of auxiliary heater. It this case it may be a signal of auxiliary heater control lamp or OEM timer signal that switches the heating unit. To control the heater only one of the wires must be connected, if the control signal is +12V – use white-yellow wire, if control signal is ground use brown-yellow wire.
From the user side the operation of mode 1 is similar to mode 2. The heater is turned on after receiving a switch on command: permanently or for certain time (from 1 second to 999 minutes). The device is turned off after receiving switch off command or when the time goes out.
Operation of relay - switch on command
After receiving a switch on command DS512 checks AUX module status lines if the controlled device is turned on or off.
- If the device is off, AUX module sends a pulse signal on relay control output. Relay enables the device switch and auxiliary heater is switched on.
- If the controlled device is turned on during receiving switch on command, AUX module does not send any pulse to the relay in order not to turn the auxiliary heater off.
Operation of relay - switch off command
After receiving a switch off command or the operation time goes out the DS512 checks AUX module status lines if the controlled device is turned on or off.
- If the device is on, AUX module sends a pulse signal on relay control output. Relay disables the device switch and auxiliary heater is switched off.
- If the controlled device is turned off during receiving switch off command of the turn off command is received after programmed operation time is out, AUX module does not send any pulse to the relay in order not to turn the auxiliary heater on.
In mode 2 the ‘state of AUX output’ sent to the user corresponds the checked AUX module status lines and informs if the controlled device is turned on or off.
Mode 3 – trunk release control
In mode 3 the AUX module input operates as output for trunk release. It operates only if DS512 is equipped with RF module and additional remote transmitters and DS512 is configured in MODE 3 – SILENT ALARM or MODE 4 – FULL ALARM. Pushing the trunk release button on additional DS512 remote transmitter results in turning the relay on for 1 second.
In mode 3 the AUX module relay cannot be controlled by SMS or TytanGPS mobile application commands.
Mode 4, 5, 6 – vehicle lights control
In mode 4, 5 and 6 the AUX module output can control chosen vehicle lights circuit in order to use functions:
- mode 4 – coming home – enables vehicle lights during arming of DS512
- mode 5 – leaving home – enables vehicle lights during disarming of DS512
- mode 6 – coming and leaving home - enables vehicle lights during arming and disarming of
DS512
The AUX module output is enabled automatically for 30 seconds. The functions operate with OEM remote transmitters and Tytan remote transmitters. The lights go off 30 seconds after disarming of the DS512 or after opening of vehicle doors. In these modes the vehicles lights can be turned on or off remotely in any moment for certain time or constantly by SMS or TytanGPS mobile application. However during arming and disarming of the system automatic control has higher priority than remote control by SMS or TytanGPS app thus takes control of the output.
The coming home and leaving home functions are available only if DS512 operates in MODE 2 – OEM PAGER, MODE 3 – SILENT ALARM or MODE 4 – FULL ALARM.
Mode 7 – additional input
In mode 7 the AUX module output is not used thus there is no way to control it. In this mode it operates as additional input that uses one of the wires: white-yellow or brown-yellow to monitor the state of any device or electric circuit in car.
Module implements the sum of both inputs: that means the AUX module sends an input trigger information if any of the above mentioned inputs is triggered. Either +12V appears on white-yellow or ground appears on brown-yellow wire.
State of the inputs is sent in every SMS or TytanGPS vehicle status.
