Labeling Requirements

CFR 47, FCC part 15, Sections 15, 19, 109.
A device shall bear the following label in a conspicuous location on the Antenna
Controller.

OTi GMS

FCC ID: JNX-OTI-GMS-V1
Manufacturer: On Track Innovations Ltd.
This device complies with Part 15of the FCC Rules.
Operation is subject to the following two conditions:

This device may not cause harmful interference, and

1.

this device must accept any interference received, including

2.

interference that may cause undesired operation.

NOTE: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particu lar inst allat ion. I f this
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:

••••

Reorient or relocate the receiving antenna.

••••

Increase the separation between the equipment and receiver.

••••

Connect the equipment into an outlet on a circuit different from that to which

this receiver is connected.

••••

Consult the dealer or an experienced radio/TV technician for help

Changes or modifications in this equipment, not expressly approved by the party
responsible for compliance (On Track Innovations Ltd,) could void the user’s
authority to operate the equipment.

6.1 Power connections

Incoming AC power is applied to terminals L, N and GND, connected to a class 2, UL certified
transformer. This transformer converts the incoming voltage to 12VAC supplying power to the
GBI2.0 Site Controller board and the antenna controller units in the field. Please refer to
Power Supply section for transformer and fuse ratings.

connected in parallel.
Note: Use a shielded twisted pair cable.

Figure 6-5:RS422 Serial connection to

Antenna Controller Network

A single Site Controller supplies power to a limited network of Antenna Controllers.
Power supply to all system elements should take into consideration the total and
distributed current loads according to the routing topology of the supply lines with
the associated voltage drops. Class 2 limits the maximum allowed current via field
wiring to 8A. This actually means a maximum rating of about 5A for the fuse on the
transformers secondary circuit.

6.3 Transformer

The Site Controllers transformer is intended to convert the incoming AC power
(115/230) to 12VAC @ 3.3A used to power the Site Controller GBI 2.0 board and a
limited number of Antenna Controller units.

6.4 Fuses

The Site Controller’s AC supply system is protected by three fuses, one on the
transformer’s primary circuit and two (in series) on the transformer’s secondary
circuit.

To comply with class 2 requirements, the 5A slow blow fuse on the transformer’s
secondary circuit is non-replaceable. The 3A fuse placed in series with this 5A
fuse is replaceable and is intended to blow before the 5A fuse.
