 Technical Specifications

Power supply

• The operating voltage, 12-30 Volts DC is connected via power connector that can be fastened with screws

• The power supply is optional accessory, Viola Systems order code 3020, with universal 100-240VAC IEC input

• The previous power supply model (order code 3010) with two-pin connector can also be used, the extra ground is left unconnected

FunctionSymbolPin

DIN rail attachment

• Arctic 3G has grooves for optional DIN rail mounting brackets.

• Mounting accessories include two DIN rail mounting brackets and four screws. (In picture product 2620, the 2622 mounting brackets are different)

• The brackets can be installed horisontally or vertically to the bottom of the Arctic 3G gateway. This allows wide variety of installation positions.

Accessories

• The following is a list of accessories currently available for Arctic 3G Gateway 2620

3221Accessory kit: Serial console adapter, Ethernet cables, power supply

3020Power supply: 12V/1,5A with universal 100...240VAC IEC input

SIM card insertion

SIM card removal• To remove the SIM card from

the slot, press the small lever in front of the SIM card ’s notched corner. Push from up to down; not from outwards to inwards

1. Turn off the unit2. Insert the SIM card into the slot so that the contacts are

facing down and the notched corner is facing out3. Gently push the card into the slot with pointy object, e.g.

with an unfolded paper clip4. The card is in place when the notch of the card is inside

the slot and behind the spring lever

Ethernet ports• There are four Ethernet ports in the device.

Ports are compatible with IEEE 802.3i (10BASE-T) and IEEE 802.3x (100BASE-TX)

• The WAN port is for connecting upstream towards gateway to internet. If Arctic is directly connected to a computer via WAN port, a cross cable is needed

• The LAN ports support MDI/MDIX detection, i.e. both cross connected and straight connected cables can be used

• WAN and LAN ports can be interchanged

Serial ports• There are three serial ports in the device.• RS1 port is for RS-232/RS-422/RS-485 connectivity• RS2 port is for RS-232 connectivity only• In addition to the two RS-ports, the console port is also

connected with RS-232. It is differentiated from the RS1/RS2-ports by the connector type, which is RJ-45.

Serial portsSlide 1/4

RS1 port• The RS1 port can be configured for multiple formats:

RS-232, RS-422 or RS-485• Pinout:
