Notice, Cautions and Warnings

Notice The Cardinal module is not a sealed “stand alone” BreadCrumb® and is not meant to be installed in any way exposed to the outside elements. The Cardinal module requires installation inside a protected enclosure, drone, UGV, robot, or cabinet as the  module is not sealed from ingress of dust, dirt, or water.

Caution When considering a wearable deployment, care should be taken that Cardinal is not in direct contact with the body, as it can become warm to the touch during increased operation.

Notice The Cardinal module should be installed in an enclosure with sufficient heat dissipation or airflow, as the device will generate heat during times of high-level data processing. The module should be installed in an enclosure with sufficient metal contact  with a thermal conductive path to dissipate the heat of the device in operation. A fan is recommended if the ambient air around the module is at or near the limits of the device during operation.

Notice All cables should be secured properly along with the Cardinal module to provide adequate strain relief to protect the sensitive connectors and pins.
Notice Be sure to terminate any unused or disabled RF Ports using a 50 Ohm load to prevent dam- age to transceivers

Notice Cardinal should not be mounted in close proximity to other RF- generating devices. If other RF-generating devices are adjacent, care should be taken to isolate to a minimum of 10 times the wavelength of the transmitted frequencies to reduce  interference potentials.

Notice As per FCC Part 15 178919 D01 Permissive Change Policy v06 “Equivalent antennas must be of the same type (e.g., yagi, dish, etc.), must be of equal or less gain than an antenna previously authorized under the same grant of certification (FCC ID),  and must have similar in-band and out-of- band characteristics (consult specification sheet for cutoff frequencies). Any new antenna type, or higher gain antenna, approved under Part 15 requires a Class II permissive change, and the requirements of § 15.203  must be met”.
Caution Do not connect the AG1 Cardinal module to a live power supply
Notice Do not attach energized power connectors to Cardinal module. De- energize all power sources before connecting to Cardinal module to prevent damage to electronics. After connections are made, then apply power.
Notice To avoid possible damage to the Cardinal radio(s), always turn off power to the module before connecting or disconnecting external antennas.
Notice Antennas should not be directly mounted.
Notice While the Cardinal module is not tested for high shock or vibration, care should be taken when mounting the module, its enclosure, and accessories to protect them from unintended high forces.

Antennas
Professional Installation Is Required
Professional installation is required for this device and will be performed only by someoneknowledgeable of its use. Rajant Corporation will ensure that the device is only marketed andsold to professionals. The device is not sold to the general public and is sold only for industrialor commercial use by professional installers.
Notice Antenna Installation
The installer should configure the conducted output power level according to country regulations and the applicable EIRP limit. Professional installation of equipment is required to ensurecompliance with health and safety issues.

Caution Exposure to Radio Frequency Radiation
To satisfy RF exposure requirements a minimum safe distance must be maintained between thisdevice’s antennas and all persons while the device is operating. The minimum distance for thismodel is stated in the FCC chapter of this guide.
Required Antenna Separation
AG1 antennas may not be co-located. To satisfy this requirement, each antenna must be installedwith a minimum separation distance of 20 cm from the antenna of any other radio frequencytransmitter. For installations that will experience vibration or shock, all antennas should beexternally mounted and attached using cables. Low loss RF cable is recommended for cableattached antennas. If a radio port is not required for a given application, the port should bedisabled in software using BC|Commander, and a 50 Ohm terminator should be installed.

Notice Interference
To reduce potential radio interference to other users, the antenna type and its gain should bechosen so that the equivalent isotopically radiated power (EIRP) is not more than that permittedfor successful communication.

Mounting Guidelines

Notice The Cardinal module is not a sealed “stand-alone” BreadCrumb and is not meant to be installed in any way exposed to the outside elements. The Cardinal module requires installation inside a protected enclosure, drone, UGV, robot, or cabinet as the  module is not sealed from ingress of dust, dirt, or water.

• The Cardinal module should be mounted securely in an enclosure with sufficient metal contact with a thermal conductive path for heat dissipation and/or provide ample airflow as the device will generate heat during times of high-level data processing. A  fan is recommended if the ambient air around the module is at or near the limits of the device during operation. All cables (RF and Power) should be secured with strain relief.
• Cardinal should not be mounted in close proximity to other RF-generating devices. If other RF-gen- erating devices are adjacent, care should be taken to isolate to a minimum of 10 times the wave- length of the transmitted frequencies to reduce  interference potentials.
• Cardinal may be used indoors in open air with as much surface exposed as possible to maximize airflow.

Power Guidelines

The Cardinal module utilizes two possible power sources. Either by Passive PoE or direct DC Power.
The Direct DC Power connector is field installable.

Caution Do not connect the AG1 Cardinal module to a live power supply
Input Voltage Eth Port: 24v – 48v Passive PoE
It is important to note that Cardinal Module needs a Clean DC power source. Voltage spikes will damage the module. The use of a power conditioner will be needed to protect the module.

When connecting to a DC power source a 3-amp inline fuse should be installed near the power source.

Clean Direct DC Input Voltage Requirements:

• 10 to 53v VDC Absolute, 12/24/48 VDC Nominal
• Input Load Regulation < 5% (of nominal supply)
• Input Ripple and Noise < 1% (of nominal supply)
• Startup Delay based on minimal input voltage threshold of 10VDC
• Minimum Startup Load of 4W
• Input Isolation of 1500VDC typical
• DC Power Input is reverse bias protected but not reverse operational

Both Ethernet and DC power cables should be secured with strain relief near the Cardinal module to prevent damage from vibration or other movement.

Below are instructions for installing the 3-pin direct DC connector. The instructions below show how to setup a quick direct DC power using an AC/DC transformer. However, the instructions apply to other Direct DC connections.

DC Power Connector Assembly Instructions:

• Note the location of the Positive wire – The one with white-dashed line
• Add DF3-crimp pin to the Pos and Neg wires, using an appropriate crimp-tool (DF3-TA2428HC or equivalent) o If crimp tool is not available soldering on the pins and manually crimping them is acceptable
• Slide a 1-inch piece of 3/32 inch heat-shrink-tubing onto the power wire
• Insert the appropriate crimped wires into the DF2-3S-2C connector, noting where Pin-1 is (notch)
• See chart below (1-Pos, 2-NC, 3-Neg) (Connect the crimped-wire with white-dashed line to Pin-1 Pos)
• Slide heat-shrink tubing into place and apply appropriate heat to shrink it down

Antenna Guidelines

Notice As per FCC Part 15 178919 D01 Permissive Change Policy v06 “Equivalent antennas must be of the same type (e.g., yagi, dish, etc.), must be of equal or less gain than an antenna previously authorized under the same grant of certification (FCC ID),  and must have similar in-band and out-of- band characteristics (consult specification sheet for cutoff frequencies). Any new antenna type, or higher gain antenna, approved under Part 15 requires a Class II permissive change, and the requirements of § 15.203  must be met”.
Rajant has certified Cardinal under FCC part 15 with the following Rajant antennas, to permit maximum power high performance use, and minimal footprint dual-band dual-port MIMO use:
KMA-2400-5-NM — Vertically Polarized Dipole, Omni-Directional, 2.4-2.5GHz, 5dBi
KMA-5800-6-NM — Vertically Polarized Dipole, Omni-Directional, 5.7-5.9GHz, 6dBi
KMA-5250-7-NM — Vertically Polarized Dipole, Omni-Directional, 5.15-5.35GHz, 7dBi
RLP-2450-5-4-SM (PUCK-12) — Vertically Polarized, Omni- Directional, 2.4-2.5/5.0-7.2GHz, 5dBi
The maximum gain certified is 7db
If Cardinal is deployed with one of the antennas certified by Rajant or with an alternate Rajant approved antenna which is of the same type and equal or lesser gain, Rajant’s modular certification may be leveraged. With this approach, the final product should  only require FCC Digital emissions testing: Part 15B. Otherwise, you will have to complete radio certifications for every country you deploy Cardinal in.

Unlike most Rajant BreadCrumb products, the Cardinal module utilizes standard SMA female type antenna connectors rather than N type connectors. The Cardinal module does not use RP-SMA type connectors.
This needs to be taken into consideration during the installation of coax as these connectors are more susceptible to damage. Coax should be secured with strain relief near the Cardinal module to prevent damage from vibration or other movement.

Notice Be sure to terminate any unused or disabled RF Ports using a 50 Ohm load. See link below.
