1. Overview ADH-02 is a data acquisition module with IoT gateway functionality. It can be used as a standalone data harvester as well as a proxy, linking a cloud with IoT mesh. ADH-2 has onboard a range of industrial interfaces that can be extended thanks to modular device architecture. It can be powered via dual-source prioritized power supply input that enables battery back-up functionality. The board requires external LTE and GNSS antennas connected with u.FI connectors. 1.1. Cautions & Warnings TYMIQ provides all the documentation, design resources, web application and other resources...

5. Getting starting 5.1. Powering-up ADH-02 ADH-02 can be powered by connecting power source(s) to one of two or to both “EXT POWER” and “BATT POWER” connectors. Both power inputs are +-40V tolerant and have under- and overvoltage protection enabling device operation in 5-25V range. Both inputs have reverse polarity protection. The difference between “EXT POWER” and “BATT POWER” is in priority only - “EXT POWER” is of higher priority comparing to “BATT POWER”, and therefore even if battery, being connected to “BATT POWER”, provides higher voltage than power source connected to “EXT POWER”,...

5.2. Antennas connection ADH-02 is designed to work with external LTE and GPS antennas. External antennas can be connected directly to u.Fl connector or via u.Fl to SMA adapter. While connecting antennas, users should follow antenna connection rules described in a datasheet provided by antenna manufacture in order not to lower device RF performance. 5.3. SIM card installation ADH-02 supports micro-SIM cards which are to be inserted as shown in the picture above. SIM card socket is of Push-Push Eject type. __________________________________________________________________ User Manual Version...

5.4. Analog IOs ADH-02 contains a powerful on-the-fly reprogrammable 4-inputs-outputs subsystem. Each channel can be individually programmed to act as: ● ● ● ● ● ● 4-20 mA digital input 4-20 mA digital output 0-10V analog input 0-10V analog output Digital input RTD measurement __________________________________________________________________ User Manual Version 1.0 11 prylada core (ADH-02 rev1.0) Document Number: tymiq

5.5. Digital Inputs ADH-02 is equipped with three 20V digital inputs sharing one ground pin. 5.6. Digital Outputs ADH-02 contains 1 high-side and 1 low-side low-side switches. Pictures below depicts: ● low-side switch connection - the switch commutates LOAD connection to ground. __________________________________________________________________ User Manual Version 1.0 12 prylada core (ADH-02 rev1.0) Document Number: tymiqum0000120

High-side switch connection – the switch commutates LOAD to power source 5.8. Relay ADH-02 is equipped with bistable relay letting user to leave some device being powered even if ADH-02 is off __________________________________________________________________ User Manual Version 1.0 13 prylada core (ADH-02 rev1.0) Document Number: tymiqum000012

5.9. External sensors power supply In case sensors, connected to ADH-02, require to be powered from ADH-02 there is 3.3V output with 300mA current limit. It gets active as soon as the isolated power domain is on. __________________________________________________________________ User Manual Version 1.0 14 prylada core (ADH-02 rev1.0) Document Number: tymiqum0000120

6. Using the System 6.1 Connectors ADH-02 is equipped with miniature 2.5 pitch AVX connectors of 9276 series compliant with wires up to 1 mm diameter. Like any connector of this type, it imposes certain requirements on how the wires should be prepared, and how they should be removed. ● Wire strip length must be 4-5 mm ● Wire can be removed with use of special tool only provided by manufacturer or its equivalent provided by TYMIQ 6.2. Running ADH-02 The following steps are to be performed to make ADH-02 running: 1. Mount ADH-02 in housing if necessary 2. Attach power supply according to the...
