Page 3: Introduction
Introduction The SiteManager models 1029, 1039, 1429, 1439, 3229, 3239, 3429 and 3439 are equipped with 2 x digital input and 2 x digital output ports that can be used to extend the primary functionality of the SiteManager. The Input ports can be used to trigger alerts sent as email messages from the GateManager, or trigger an SMS sent from SiteManager itself (SMS alerts are only applicable to models with integrated 3G modems). -
Page 4: Digital Input Ports
Digital Input Ports IMPORTANT: Examples in the following are only for illustration of the func- tionality. Always consult the specifications of the equipment you intend to connect. 2.1. Electrical information Input port toggling on the SiteManager would typically be controlled by a mechanical switch or a relay connected to the GND and Input terminals. -
Page 5: High-Side Output Switching Equipment Example
2.4. High-side Output switching equipment example When an input port of the SiteManager is connected to equipment that has “high-side switching” connections on the output, you must apply a circuitry to pull the output towards zero. The following example uses a 24V relay, which subsequently assumes the output of the equipment to support 24V operation (the coil voltage). -

If you want to use Input 1 for another purpose, you can disable the current action. Enter the menu GateManager > General and press the [More>>] button. The control of the "Input 1 Action" will be shown, and you can define it to trigger and alert instead. -

Page 8: Digital Output Ports
Digital Output Ports 3.1. Electrical information The output ports of the SiteManager are of the “open drain” kind, which means that (just like a switch) no voltage is output by the port itself, but must be controlled from a circuitry supplied by an external source (max 24V) or from the Vout (5V) pin. -
Page 9: Low-Side Input Switching Equipment Example
3.3. Low-side Input switching equipment example. When an output port of the SiteManager is connected to equipment that has “low-side switching” conductor connections on the input, you can use the SiteManager output ports directly without any external components (such as pull up resistors or relays). -
Page 10: High-Side Input Switching Equipment Example
3.4. High-side Input switching equipment example. When an output port of the SiteManager is connected to equipment that has “high-side switching” conductor connections on the input, you must apply additional circuitry to pull the output towards +. Be careful about just applying a resistor to pull the output high, as the effect and resistor value must be calculated based on the power consumption and switching voltage level of the attached equipment. -
Page 11: Changing Output 2 Default Functionality
3.5. Changing Output 2 default functionality As mentioned previously, Output 2 can be configured to signal when a GateManager connection is available. In the SiteManager menu GateManager > I/O you can determine if this ac- tion is enabled, which is not the case in this screen shot: If you want to enable Output 2 to go active when a GateManager connection is operational, you can enable this by entering the menu GateManager >... -
