• For EN/IEC 60950-compliant grounding a size 18 AWG (12 mm) or larger copper wire and an appropriate user-
supplied ring terminal is used for the installation.
IMPORTANT NOTE:
iO Gateway must be grounded. NEVER remove the ground conductor or operate the equipment in the absence of
a suitably installed ground conductor. It may be necessary to contact the appropriate electrical inspection
authority or an electrician to ascertain that a suitable grounding is available.
Follow these steps to install the ground connection:
1. Strip one end of the ground wire to the length required for the ground lug or terminal.
2. Crimp the ground wire to the ground lug or ring terminal using a proper wire crimper of the appropriate
size.
3. Attach the ground lug or ring terminal to the chassis as shown in the figure below. Use the nut and lock
washer provided. Tighten the nut securely.
Figure 4 - Chassis Ground
1.3 DEVICES CONNECTION TO IO GATEWAY
Devices that are not manufactured by Multitel can be connected to iO Gateway. These devices are commercially
available and should be qualified before being installed by competent personnel. Each device carries its own
technical specifications that are not made available in this user guide. Please refer to the manufacturer’s technical
documentation for each equipment specifications.
Following are the technical limitations when connecting a device to the iO Gateway:
•The industry-standard Modbus TCP/IP and SNMP protocols are supported;

•Communication ports are available on Ethernet 1/Ethernet 2 and/or both RS-485 ports;
•Ethernet Speed can be adjusted from 10 Mbps, 100 Mbps or 1Gbps (only Ethernet 1). An Automatic
speed option can also be selected.
•Each Equipment Polling Rate and Time Out can be adjusted.
1.3.1 ETHERNET PORTS CONNECTION
iO Gateway comes with two separate Ethernet ports, a 10/100Mbps port is available on the front panel and a 1Gbps
port is available on the back panel. iO Gateway can support in up to 128x devices with Modbus TCP/IP and in up
to 128x devices with SNMP protocol. Please note that these numbers might not be achieved because of the
limitation of the device computing power. The actual limit will depend on the number of data points of each device,
and the polling rate.
Figure 5 - Front Ethernet Ports
Figure 6 - Back Ethernet Ports
Multitel recommends the use of a straight Cat-5 cable. Both Ethernet ports come with RJ45 connectors. Commercial
Cat-5 cable can be used or Cat-5 cable can be made using the following pinout.

RS-485 wiring can be complex when multiple devices are connected. When running wires for long distances, RS-
485 networks should always be wired in a bus (or daisy-chain) configuration. The bus should start at the iO
Gateway and then be run to each meter in turn. Branches and “home-run” wiring (i.e. each module is wired back
to iO Gateway individually) should be avoided. For best results, especially when running longer distances,
shielded twisted-pair cables should be used to prevent interference. NB: Shielded cable should be connected
to ground at one end only.
RS-485 connectors are found on the backplate of the iO Gateway module. There are two independent RS-485
connectors: COM A and COM B. The block used to connect to the COM ports needs to be a 3x position terminal
block header, male pins, shrouded (4 Side) 0.138" (3.50mm) 90°, right angle through holes.

Figure 8 – iO Gateway Power Input and Fail
2.1 WIRING POWER INPUT
iO Gateway is powered by a continuous -48Vdc power source. The module is equipped with A & B feed positions
for power redundancy. Power Input status can be found in the General Parameters – System Information.A
readily accessible disconnect device shall be incorporated within the power wiring in order to disconnect the
equipment from the 48Vdc supply for servicing.
Using a wire-stripping tool, strip each of the four wires coming from the DC-input power source to 0.25 inch (6.3
mm) + 0.02 inch (0.5 mm). Do not strip more than 0.29 inch (7.4 mm) of insulation from the wire. Stripping more
than the recommended amount of wire can leave exposed wire from the terminal block plug after the installation.
