frogLink Message Mode/ASCII Mode <-> MOBOTIX

Application Note 1/2019 — connecting the frogLink Bluetooth LE USB stick to a MOBOTIX camera's serial interface to communicate with frogblue components.

Using the USB interface of the MOBOTIX camera, it is possible to connect the frogLink Bluetooth LE USB stick as a serial FTDI interface so as to establish communication with the frogblue components.

The first part of the instructions that follow describes correct connection of the frogLink and configuration of the serial interface.

In the second part, some scenarios are described using example configurations.

frogLink connected to a MOBOTIX camera — system overview

Admin Menu -> Hardware Configuration -> Manage Hardware Extensions

Hardware Configuration — Manage Hardware Extensions

USB Connector — connect frogLink as Ext IO (USB)

Do not connect frogLink to the USB cable of the MOBOTIX camera until instructed!

Notice dialog: insert USB stick and press OK

Connection successful ->

USB Connector — connection successful, Disconnect available

Save permanently and restart!

2. Serial interface configuration

Admin Menu -> Serial Interface

Serial Interface — Setup of serial interface, modem and weather station

Select “Data” operating mode

Serial Interface and Modem Setup — select Data operating mode

3. Serial Interface settings

| Setting | Value | | | | | Serial Interface | Data | | Transmission speed | 115200 bps | | Line end character | LF |

Permanent storage and restart

Serial Interface and Modem Setup — settings Data / 115200 bps / LF

4. Terminal

Admin Menu -> Serial Interface

Serial Interface — open Serial Terminal

Serial Terminal — $messages request listing parameterised messages

$ – Requests allow you to retrieve details of messages, rooms and project information available.

The request $message or $messages produces a list of all messages parameterised on the frogLink.

All listed messages can be executed by entering the message name.

Serial Terminal — executing the FrontDoorLight message

Messages with optional parameters (in parentheses) can also be executed ->

FrontDoorLight(time=15s,bright=85)

Serial Terminal — FrontDoorLight with time and bright parameters

Parameters available

| Parameter | Meaning | | | | | ON | Instead of switching the current state, the outputs are switched on. | | time | The outputs are switched on for this time. (s = seconds, m = minutes, h = hours) | | bright | Dimming value of the output (if possible) |

Example Scenarios

  1. Activate or deactivate recording using frogKey
  2. Recording at door opening using frogEntry2-3 and additional light input Switch with frogDim1-3
  3. Open door with pin on MX keypad and additionally with frogKey

A prerequisite for these scenarios is that the frogLink of the respective MOBOTIX camera is correctly parameterised and connected to the USB interface.

Scenario overview — camera, frogLink, contacts, bell wire 100m, door opened

Scenario 1: Activate and deactivate recording using frogKey

  1. Create two messages “RecordingEnable” and “RecordingDisable” and write the altered configuration to the frogLink.

New Message RecordingEnable

New Message RecordingDisable

frogProject configuration — write messages to the frogLink

  1. Parameterise frogKey

Parameterise frogKey — one click up/down

One click upwards -> recording is activated

One click downwards -> recording is deactivated

  1. MOBOTIX-camera configuration

Create two network messages ->

Admin Menu -> Transfer Profiles -> Profiles for Network Messages

Example Profile 8 (frogRecordingEnabled):

IP Notify Type      = Custom Configuration
Destination Address = 10.16.15.75:80  (Parallel send to all)
Data Protocol       = HTTP/1.0 Request
                      /control/control/
                      admin:meinsm
Data Type           = Plain text
                      ?set&action=recording&recording_active=enable

Network message frogRecordingEnabled — transfer profile

Example Profile 7 (frogRecordingDisabled) analogously with ?set&action=recording&recording_active=disable:

Network message frogRecordingDisabled — transfer profile

Create two message events ->

Setup Menu -> Event Control -> Event Overview -> Message Events

Message events frogRecordingEnabled / frogRecordingDisabled — Event Sensor Type COM In, String Compare

Create two action groups ->

Setup Menu -> Event Control -> Action Groups Overview

Action group frogRecordingEnabled — IP Notify

Action group frogRecordingDisabled — IP Notify

Save permanently and restart.

Recording is now activated with one click upwards, or deactivated by one click downwards.

Scenario 2: Recording at door opening using frogEntry2-3 and additional light input Switching with frogDim1-3

  1. Create two messages “DoorIsOpen” and “FrontDoorLight” in frogLink.

Door contact is connected to input 1 of frogEntry2-3.

Light input is connected to the output of frogDim1-3.

Messages DoorIsOpen and FrontDoorLight in the frogLink

Input In — DoorIsOpen

Output Out — FrontDoorLight

  1. MOBOTIX-camera configuration

Create message event ->

Setup Menu -> Event Control -> Event Overview -> Message Events

Message event frogDoorIsOpen — COM In, String Compare DoorIsOpen

Create network message ->

Admin Menu -> Transfer Profiles -> Profiles for Network Messages

CGI-path =

/control/rcontrol?action=PutRS232&rs232outtext=FrontDoorLight(time=10s;bright=75)

Network message FrontDoorLight — transfer profile with CGI path

Create action group ->

Setup Menu -> Event Control -> Action Groups Overview

Action group frogDoorIsOpen — IP Notify FrontDoorLight

Activate recording on door opening ->

Setup Menu -> Event control -> Recording

Recording (REC) — Event Recording on frogDoorIsOpen

If the entrance door is now opened, the camera recording and the light are switched on.

Scenario 3: Open door with a pin on the MX keypad and additionally with frogKey

  1. Parameterise frogKey and frogLink ->

Create message in frogKey

Parameterise frogKey — OpenDoor, RecordingEnabled, FrontDoorLight, RecordingDisabled

Create message in frogLink and write configuration

New Message OpenDoor in the frogLink

  1. MOBOTIX-camera configuration

Create message event ->

Setup Menu -> Event Control -> Event Overview -> Message Events

Message event frogOpenDoor — COM In, String Compare OpenDoor

Create action group ->

Setup Menu -> Event Control -> Action Groups Overview

Action group OpenDoor — Device Out ~Door

The door now opens when you click twice upwards.
