top and bottom) hold the metal plates for wall mounting.
Juli 2016 VPNRouter Software Manual 14

4 Position of Connectors and Functions of VPNRouter iR5221 and VPNRouter iR 3220
The group of four in the middle is for the DIN Rail mounting clamp. This may be mounted in
standard orientation, or turned by 90 ° to provide for a (seldom used) horizontal xture on the DIN
Rail.
Figure 5a is a reference for the positions of front side connectors. It is for demonstration only.
Figure 5b shows the positions of screws for xing. Note, this is upside down with respect to the
front side. The two M3 screw positions in the middle allow to x an DIN Rail clamp. There is also
the position of a possible antenna socket near the Reset button.
4. Position of Connectors and Functions of VPNRouter iR 5221 and
VPNRouter iR 3220
First the connectors and functions located on the top side of VPNRouter iR 5221 and VPN-
Router iR 3220 are described. The next components are those on the front side, nally followed by
those on the bottom side.
4.1. Power
The VPNRouter device is powered by a single power supply in a wide range from 12 V to 50 V
DC. A suitable power supply adapter is available as add-on component, and part of the starter kit
package. Connect the cable to the power jack at the top side of VPNRouter, and plug the adapter
into the socket. The Power LED (red) on VPNRouter will light. You can connect a power supply
of your choice, providing the technical requirements are met.
Warning: disconnect the VPNRouter from power supply before performing installation or wiring.
The wire size must follow the maximum current specications. The maximum possible current in
the power wires as well as in the common wires must be taken under consideration. If the current
rises above the maximum ratings, the wiring can overheat, causing serious damage to your equip-
ment. When powered, the VPNRouter's internal components generate heat, and consequently
the outer case may feel warm to the touch.
4.1.1. Connection and Polarity
Power is connected via three clamps on a terminal block, located on the top side of VPNRouter iR 5221/VPNRouter iR 3220.
Warning: do not confuse the CAN connector at the bottom side for power input. Such may
damage the CAN bus port.
Clamp 3 2 1
Function PE V- V+
Table 4: Power Connector
V+ and V- are clamps for DC volt-
age supply. PE is the clamp to con-
nect the case and shields of con-
nection cables to Protective Earth.
PE is internally connected to logic
ground, which is on the level of V-
supply line. Figure 6: Power Connector

4 Position of Connectors and Functions of VPNRouter iR5221 and VPNRouter iR 3220
Attention: Never connect the Terminal block for power supply in reversed direction, i.e. turned
by 180 ° . This would connect the power between V- (logic ground) and case/protective ground.
High current is the result, causing damage inside the system.
4.1.2. Grounding
Grounding and wire routing help limit the eects of noise due to electromagnetic interference (EMI).
Run the ground connection from the ground screw to the grounding surface prior to connecting
devices.
In noisy environments the case of VPNRouter shall be directly connected to
Protective Earth. This is the purpose of the dedicated PE Screw on the case
top/rear side.
Figure 7: PE Screw
4.2. WLAN Switch
The WLAN switch on the top side is used to disable the WLAN function.
Provided the VPNRouter is equipped with a WLAN module. Otherwise
software may just read this switch for other purposes.
Figure 8: WLAN
Switch
4.3. Digital I/O
The functions of Digital Input and Output are located on the 13 clamp terminal block on the top
side of VPNRouter. Also available on this terminal block is the function of I ² C and an auxiliary
power output.

Input Low TTL level (0.0 to 0.8V)
Table 6: Digital Input: Electrical Characteristics
4.3.2. Digital Output
The VPNRouter provides four digital output channels. The signals OUT0 to OUT 3 are located on
clamps 7 to 10 of the terminal block, the reference GND is on clamp 6 and 11. The output ports
can source some milliAmpere output in High status, with decreasing voltage when the current rises.
In Low status they can sink signicant current, enough to drive small relays.
Output High Source 32mA@TTL (2.0 to 5.0V)
Output Low Sink 64mA@TTL (0.0 to 0.6V)
Table 7: Digital Output: Electrical Characteristics
4.3.3. I ² C Interface
The I ² C interface operates with a maximum frequency of 400 kHz (Fast Mode). The connector
for I ² C is located on the terminal digital I/O block and has three contacts: SCL, SDA and GND
(clamps 11 to 13). When required the I ² C device can be powered with the VCC auxiliary output
of the digital I/O terminal block.
4.3.4. Auxiliary Power
+5V is an auxiliary power output of 5V DC, for max. 500 milliAmpere. This may be used to drive
special driver circuits connected at Digital-I/O. For example +5V may drive a relay controlled by
the output signals, or power a small I ² C-controlled display. The GND for auxiliary power is on
clamps 6 and 11.
4.4. Antenna Locations
The VPNRouter is prepared for adding two antenna sockets of the usual SMA
type. These may be used for functions like WLAN, UMTS/LTE wireless or
GPS receivers. The positions are covered by plastic caps. Both antenna
positions are on the top side of VPNRouter iR5221/VPNRouter iR 3220.

4.5. LED
The front side starts with a group of four LEDs.
PWR (Red) lights when power is applied to the VPNRouter. System soft-
ware may generate short blinks for certain events.
3G (Yellow) is controlled by a UMTS/LTE modem card in the mini PCIe
expansion slot.
WIFI (Blue) signals operation status of WLAN function.
APP (Green) is free to use by customers application, e.g. as some ready
light.

4.6. LAN
The rst Ethernet port in VPNRouter is for 10/100 Mbps Fast
Ethernet. This connects to an internal Ethernet switch, with 2
(VPNRouter iR 3220) or 4 (VPNRouter iR 5221) external connec-
tors. Devices or systems connected to these ports can communicate
with each other, without involving the CPU of VPNRouter.
Each of the LAN ports are the usual RJ45. When the connect is
done the Link LED on RJ45 (right) will light. When data trac
occurs on the network, this LED will blink. It depends on your
network or devices whether a 100 Mbit or a 10Mbit connect will be
established. The Speed LED (left) lights for 100Mbps connections. Figure 12: LAN ports
4.7. WAN
The second Ethernet port in VPNRouter is for 10/100/1000 Mbps
Gigabit Ethernet. The connector is the usual RJ45, integrated
with USB ports.
When the connect is done the Link LED on RJ45 (green, left)
will light. When data trac occurs on the network, this LED will
blink. It depends on your network or devices whether a 1000Mbit,
a 100 Mbit or a 10 Mbit connect will be established. The Speed
LED (yellow, right) lights for 10 and 100 Mbps connections.
This Ethernet interfaces supports Auto-MDI(X) feature.

4.8. USB
The VPNRouter provides two USB 2.0 Host interfaces. They can be used for Mass Storage Devices,
like Flash- or Hard Drive, Bluetooth and WLAN adapters etc.
The ports are integrated with the Gigabit Ethernet WAN port, see gure 13.

4.9. Serial
VPNRouter iR 5221 and VPNRouter iR 3220 provide two DSub-9 male connectors. All three modes
of operating RS232, RS422 or RS485 are entirely congurable by software. For the pinout refer to
the Table 8. If the conguration by software is not used, the default operation mode of each port
is congured by a DIP switch. The DIP switch may be overridden by software, if the user chooses
to do so. Check section ?? on page ?? for details.

Ports
Please note the function of the GND signal in RS422 and RS485 modes: this signal must also be
connected between the serial devices. So in reality a 2-wire and a 4-wire connection need 3 wire
and 5 wire respectively. With the exception of very special congurations, a serial connection in
RS422/RS485 mode without GND connection violates the specications for RS422 and RS485
standards.
4.9.1. DIP Conguration for Serial Ports
The right side of the case has a small opening slit. This is provided to access
the DIP switches for serial conguration. With a small pen or screw driver
the conguration can be changed without opening the case.
The current setting of the switches is readable by software. If the user or
software decides to do this, the software can override the active conguration,
i.e. change the operation mode. Please check section ?? on page ?? for details
about this function.

4.10. SD-Slot
The VPNRouter provides an SD-Slot on the front side of the case, for cards
in standard size. The slot supports cards as SD 2.0 or SDHC type, to allow
up to 32 GB of capacity. Class 10 cards are supported as well.
If an operating system is installed on the SD Card, the VPNRouter will boot
this software. Figure 16: SD and
