1. SiteManager 3134 I/O port overview
1.1. Digital Input Ports
INPUT PORT toggling on the SiteManager would typically be controlled by a
mechanical switch or a relay connected to the GND and Input terminals of
the INPUT port. The INPUT port is when not connected, in Open state (corresponds
to a connected mechanical switch is turned OFF).
Optionally you can control the input port by a digital output from another device.
To retain the Open state (switch is turned OFF), the output level from
the other device must be open-drain or between 3-12 V. To activate Closed
state (corresponds to mechanical switch is turned ON), the output level of
the other device must pull down the INPUT port to 0-1 V (pull down current is
0.35mA).
Input port 1 is default assigned to toggle GateManager Access. By connecting
a simple on/off switch you can control when remote service should be allowed
(see also section 3 Control GateManager access on Input1)
1.1.1. Low-side switching equipment.
When an input port of the SiteManager 3134 is connected to equipment that
has “low-side switching” conductor connections on the output, you can use
the SiteManager input ports directly without any external components (such
as pull up resistors or relays).
1.1.2. High-side switching equipment
When an input port of the SiteManager 3134 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 24 V relay, which subsequently assumes the
output of the equipment to support 24V operation (the coil voltage).

1.2. Relay Controlled Output Ports
The SiteManager 3134 output ports functions as relays that toggle by software
triggers set in the SiteManager GUI. (You can actually hear the relays
click when activated)
An open output port support a maximum of 30 V DC / 1 A or 42 V AC / 0.5 A.
Output port 1 is dedicated to go active when a LinkManager is connected,
and can be used to turn on a lamp that notifies the users that the device is
being serviced. (See example of use in section 4 Trigger Alert on LinkManager
connect)
1.2.1. Low-side and High-side switching equipment.
The 3134 has electromechanical relays with both NC and NO, so it can be
used for either high side or low side switching equipment without further peripheral
circuitry.
2. SiteManager 1029/3229 I/O port overview
WARNING: Do NOT under any circumstances apply voltage
(regardless of polarity) between the –V and GND pins on the
SiteManager. Doing so will permanently damage the power
regulators inside the SiteManager!
NOTE: Examples in the following are only for illustration of the functionality.
Always consult the specifications of the equipment you intend to connect.
2.1. Digital Input Ports
Input port toggling on the SiteManager would typically be controlled by a
mechanical switch or a relay connected to the GND and Input terminals. The
Input port is when not connected in “Open state” (inactive) that corresponds
to a connected mechanical switch is turned OFF. An input toggles to “Close
state” (ON) when pulled from 2.34 V or above to 0.16 V or below.
The behaviour for input voltages between 0.16 V and 2.34 V is undefined.
There is an internal 10 Kohms pull-up resistor to 3.3 V, so an unconnected
input port is in the “OFF” state.
Input port 1 is default assigned to toggle GateManager Access. By connecting
a simple on/off switch you can control when remote service should be allowed
(see also section 3 Control GateManager access on Input1)
2.1.1. Low-side switching equipment.
When an input port of the SiteManager 1029/3229 is connected to equipment
that has “low-side switching” conductor connections on the output, you
can use the SiteManager input ports directly without any external components
(such as pull up resistors or relays).

2.1.2. High-side switching equipment
When an input port of the SiteManager 1029/3229 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 24 V relay, which subsequently assumes the
output of the equipment to support 24V operation (the coil voltage).
2.2. Digital Output Ports
The output ports of the SiteManager 1029/3229 are of the “open drain” kind,
which means that (just like a switch) no voltage is output by the port itself,
but must be supplied either from an external source (max 24 V) or from the
Vout (5V) pin.
In the “OFF” (inactive) state, the impedance is min 24 Mohms; in the “ON”
(active) state, the impedance is max 0.5 ohms.
Output port 1 is dedicated to go active when a LinkManager is connected,
and can be used to turn on a lamp that notifies the users that the device is
being serviced. (See example of use in section 4 Trigger Alert on LinkManager
connect)
Maximum sink current is 0.2 A.
2.2.1. Low-side switching equipment.
When an output port of the SiteManager 1029/3229 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).
The ports of the SiteManager should be powerful enough to pull a relay directly
(even a electromechanical one).

2.2.2. High-side switching equipment.
When an output port of the SiteManager 1029/3229 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.
A safer setup will be to use a Relay.
The following example uses a 5 V relay, which means you can use the Vout
of the SiteManager to pull the output high.
In the following example a 24 V relay is used, which means an external
source must keep the level high. Note that –V and GND must be connected
when using an external source:

3. SiteManager I/O port State configuration
You can control in the SiteManager Web GUI how the I/O ports should work.
State is controlled in menu System I/O
The alert trigger is defined in the menu

4. Control GateManager access on Input1
Input port 1 of the SiteManager is per default assigned to toggle GateManager
access to the SiteManager.
Toggling this port ON, will prevent the SiteManager from connecting to the
GateManager and subsequently a LinkManager to connect to the SiteManager
or equipment connected to the SiteManager.
Toggling the port ON can be done by simply applying an analogue switch:
When activating the switch the port will toggle ON.
On the SiteManager 3134 the Active LED will enter yellow slow-blink mode.
On the SiteManager 1029/3229 the status LED will flash to short-blinks and
pause.

5. Trigger Alert on LinkManager connect
Setting up an alert on LinkManager connect may not be used in real life, but
is a good exercise in understanding both the IO ports and the Alert system.
You do not have to configure anything in the SiteManager web GUI. The below
example is based on the default settings.
The setup is simply to utilize the default output port 1 of the SiteManager that
toggles on LinkManager connect, and which is intended to connect to a
warning light so the machine operator will know that service is conducted on
the machine. Instead we connect this output port to Input port 2 of the Site-
Manager, and then associate a GateManager Alert to this port.

5.2. SiteManager IO setup.
In the SiteManager make sure that it is configured to trigger alert INPUT2 if
ON (this is the default value).

5.3. GateManager Alert setup
1. Enter the GateManager console, and switch the “Alert Rules” view. Right
click the domain, and select “Create Alert”.
2. Select “SiteManager” in the Appliance Product list.

3. Provide a meaning full name, and select Edit:
4. Scroll down the Parameters list to “Input 2 Active” and double-click it. This
will insert “INPUT2” above in the Alert expression field. Since this is a Boolean,
no further expressions are needed.
5. Click OK to return to the Alert rules view. Right click the new Alert rule and
select Share Alert rule.
6. Click Yes to accept to share with lower-level domains.

Alert Rules”:
8. In the Alert Rules section, tag the new Alert, and enter the email that should
receive the alert. Click OK to save.
