Digital inputs of Ethernet controllers are connected via

Testing and evaluation of GSM modules and controllers LevelManager demo of home automation Ethernet eHouse @ Home Automation eHouse.Pro
Smart home demonstration module midwest living eHouse4Ethernet allows testing and evaluation of all controllers. Evaluation Module is an intelligent building eHouse almost all hardware resources stored on one replacing the PCB production plant at home. Demonstration module connection to the controller is very simple and requires only a connection between midwest living the appropriate connectors and a microprocessor controller demo PCB. Ethernet controllers can be divided into two main variants of the hardware: large controllers midwest living - based on PCB CommManager / LevelManager controllers medium - based on EthernetRoomManager PCB In this post we will discuss the testing and evaluation of large controllers (based on CommManager / LevelManager) with Ehouse4Ethernet DEMO module.
To fully analyze the behavior of the controller should be connected to the LM / CM connector that between demo module and LM / CM: Unclip all the wires from the terminals to the "TEST" section 50 pin flat tape outputs (S18) connector "You Relay 1". And remove the jumper "ERM Power" in connection s18 50 pin flat tape outputs (S17) connector "Relay midwest living or 2". And remove the jumper "ERM Power" in connection S17 20 pin flat strip (J5) for Analog / Digital converters. Connect the power cord - connector "Power" between CM / LM and demo module next step is an appropriate combination of sensors connected to the inputs of the ADC. Remove jumper "Light", connecting light sensor ADC. The next step is to configure the remaining temperature sensors, connected to the required inputs. Look for 2x32pin, allowing people to connect sensors LM335 or MCP970x to any input of the LM / CM. You can choose one type of sensor. Activation of the sensor also provides connection LM335 "Pull Up" resistor 3V3 which provides power to the sensor. This is a much more secure connection to the sensor midwest living than full - powered sensor circuit, as the sensor pins are not touching midwest living power. But LM335 Detector for Ethernet controllers do not have the full - scale measurements and can measure temperatures up to about 56 degrees C. . In case of very low temperatures can also effect midwest living of heating midwest living itself by overcurrent, because these sensors are working optimally for 5V supply voltages. midwest living For example, connect the sensor D 'of LM335 No. 7, in the 32 - pin connectors remove midwest living the jumper in row 7 for MCP970x and short - circuit for LM335. Connect the sensor D 'MCP970x the No. 6 to 32 - pin connectors remove the jumper in row 7 for LM335 and close to MCP970x. Be aware that, depending on the type of controller (such as hardware and interconnection module) part of the inputs can be connected on a printed circuit midwest living board. Please refer to the detailed documentation of the controller, measuring sensors that are not physically connected to other resources. Failure to use the controller, which is all free as measuring inputs (EHM, ESM) should decrease the connection D 'is a free controller (3, 5, 6, 7, 8, 9, 10, 11, 12 , 13, 14, 15, 16). The next step is to connect the router or switch to a controller via Ethernet LAN RJ - 45. After checking and verifying that all cables are correctly connected and tightened 12VDC power supply can be connected to the module demo board which is also the power to the controller. Digital Out Expanded Testing
States of the digital outputs are displayed on the LEDs are under "Outputs" evaluation module. Which LED lights for its incorporation and the corresponding output is equivalent to the inclusion of a relay in the production system. Demonstration unit has two independent "Outputs" section that allows you to check all outputs simultaneously large controllers (CM, LM, etc.). It is opening jumpers "ERM Power" section of each of the "Outputs" as Large Ethernet controllers are derived by high voltage on these joints. Power connection in this way can cause major damage to the controller. They should eat a normal power cable as standard power connector controllers. Testing of Digital Inputs
Digital inputs of Ethernet controllers are connected via "Pull Up" resistors power controller (3V3). It is necessary to activate D 'shorted to ground control (for LM) and disconnected from the ground for (LM). Due to this, event control system that can be passed midwest living from a variety of sources, mono - stable (bell) switches are used. This prevents the performance of collision midwest living events midwest living when the switch forces such as the inclusion of an external panel on the output we get the event in the same output. Inputs (12) are connected directly to the Ethernet switch module demo ("micro midwest living switching") Does that
