Introduction
SiteManagers are equipped with 2 x input- and 2 x 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 or SMS messages from the GateManager, or trigger an SMS sent from SiteManager itself
(SMS alerts are only applicable to xx39 models with integrated 3G modems).
Additionally an Input port can be used to control when remote access is possible.
The Output ports can be used to trigger a signal to e.g. a PLC or HMI, based
on manually toggling of a button in the SiteManager GUI. Additionally an
Output port can signal when remote access is made via the SiteManager, or
simply when the SiteManager is connected to the GateManager.
1.
About GND, 0V GND and Shield
On the SiteManager the power should be applied between GND and +V as
shown.
Models: 10xx, 14xx, 32xx, 34xx
Models: 11xx, 33xx
Voltage 12-48V
Voltage: 12-24V
On some industrial equipment, you will find that power should be supplied
between terminals marked -V or 0V and +V, and where -V/0V, GND and
Shield may have different potentials. The specifications for a USB port is that
GND and Shield should have the same potential, and since the SiteManager
has a USB port, the GND and Shield is per design short circuited internally.
It is also intentional that there are no separate -V/0V pins on the
SiteManager, since the presence of the USB port would make it extremely
difficult to protect the power regulation circuitry in the SiteManager, should
you by accident apply voltage between -V/0V and GND.
This would typically not be an issue even in cases where GND and Shield
are wired separately.

Digital Input Ports (ALL SiteManager models)
IMPORTANT: Examples in the following are only for illustration of the functionality. 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. 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 behavior for input voltages between 0.16 V and 2.34 V is undefined.
In the SiteManager there is an internal 10 Kohm pull-up resistor to 3.3 V, so
an unconnected input port is in the “OFF” state.
2.2. Digital Input ports default functionality
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 2.5 Changing Input 1 default functionality)
Input port 2 is not associated with anything as default.
2.3. Low-side Output switching equipment example
When a digital input port of the SiteManager 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).
A typical use is the following, where a mechanical single pole switch is connected between Input 1 and GND.
+24V
SM
+V
In1
GND
0V
This exploits the default use of Input 1, which is to control the remote access. Short circuit of Input 1 and GND will by default disable the
GateManager connection.

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).

2.5. Changing Input 1 default functionality
As mentioned previously, Input 1 by default controls remote access.
In the SiteManager menu System > I/O you can determine if the default action is enabled, which is the case in this screen shot:

Page 5 of 13
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.
2.6. Defining Input port Alerts
Alerts resulting from triggering Input ports can be sent locally from a
SiteManager as SMS (xx39 models only), or via the GateManager as Email
or SMS (all models).
Refer to the separate guide “SiteManager Working with SMS and Email
Alerts” available in the support section on the Secomea web site.

Digital Output Ports
NOTE: This section applies to:
Output port 1 and 2 for models 10xx, 14xx, 32xx, 34xx
Output port 2 only for Models 11xx and 33xx
3.1. Digital Output ports - Electrical information
The digital output ports 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.
Do NOT apply voltage (e.g. 24V) directly to a SiteManager Digital Output port, as this could permanently damage the port.
In the “OFF” (inactive) state, the impedance is min 24 Mohm; in the “ON”
(active) state, the impedance is max 0.5 ohm.
Maximum sink current is 0.2A, which means the Output port is protected by
0.2A fuses mounted in extension to the FET transistors of the Output ports;
but it is still very important to dimension the external circuitry to not overload
the ports. At 24V you should therefore apply pull-up resistors at minimum
24V/0.2A = 120 ohm (24V*0.2A = 4.8W), but it is recommended to not exceed 3W, meaning a pull-up resistor of 220 ohm is recommended. These
pull-up resistors must be applied externally, unless you are using a relay
which has high enough impedance.
A 12V or 24V relay can be applied to an output port directly if the relay is
supplied with the corresponding working voltage (12V or 24V respectively)
and with a "trigger current" at max 0,2A. (A larger relay would require more
current, and subsequently would require an additional "assisting" relay for
the SiteManager output ports to trigger it)

3.2. Low-side Input switching equipment example.
When a digital output port of the SiteManager is connected to equipment
that has “low-side switching” conductor connections on the input, you can
use the SiteManager’s digital output ports directly without any external components (such as pull up resistors or relays).

With a “trigger current” of 0,2A, the digital ports of the SiteManager should
also be powerful enough to pull a relay directly (even an electromechanical
one).
You could also choose to control e.g. a 24V LED light tower up to 4.8 Watts:

3.3. High-side Input switching equipment example.
When a digital 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.
A safer setup will be to use a Relay.
The following example uses a 5V relay, which means you can use the Vout
of the SiteManager to pull the output high.

The Relay Output1 is a “dual pin” port where both pins are isolated when
OFF and short-circuited when ON.
Maximum sink current is 0.5 A. Maximum Voltage is 24V.

By default Output 1 is configured to go ON when Output port 1 is by default
configured to go active when e.g. a LinkManager is connected, and can be
used to turn on a signal that notifies the users that the device is being serviced. The signal could be a LED light tower up to 12 Watts.

Output ports default functionality
Output port 1 is by default set to go active when connecting to the
SiteManager or its Agents, using LinkManager, LinkManager Mobile or the
“Go To Device” buttons from GateManager. The purpose is to signal, e.g. by
turning on an external warning light, to the local service people that the machine is currently being serviced remotely.
Output port 2 is by default set to NO predefined action, but it can be configured to the same values as Output 1. I.e. if you want to use a digital Output
port 2 on a SiteManager 11xx or 33xx model to signal remote service, and
use the isolated Output ports 1a/1b for other purposes, you can change this
under GateManager > General > [More>>].

When an Output port function is selected for an Output port under
GateManager Settings, the active state will be displayed as follows under
System > I/O.
5.1. Manual toggling of Output port state
Both Output ports can be manually set ON or OFF via the toggle button in
the SiteManager web GUI under System > I/O.
Note that an Output that is triggered ON by a value defined under
GateManager Settings as mentioned above cannot be forced OFF.
