1.6 RF Exposure Information
READ THIS INFORMATION BEFORE INSTALLING THE TELEMETRY DEVICE
The OMNIDATA device contains a transmitter and a receiver. When it is turned on, it
receives and it may transmit radio frequency energy in the 900MHz band. During
transmission, the output power level at the antenna port varies over a range from 0.125
to 1 watt. The paging carrier service provider controls the output power level.

Document Number: 9400.01484-USG01 Revision 1.6 12/2/2002
The antenna used for this transmitter must be fixed mounted in a permanent structure
providing a separation distance of at least 20 cm from all persons during normal
operation. The OMNIDATA is provided without an external antenna. PerComm used
the Larsen quarter-wave dipole antenna model SPWH20918 with a 4-inchx4-inch
metallic ground plane during measurements for FCC certification. If another antenna is
used its maximum gain should not exceed the theoretical dipole gain of 2.15dBi.
The maximum radiated output power of the antenna satisfies the maximum permissible
exposure (MPE) limits as specified in §1.1310 of FCC regulations for general
population/uncontrolled exposure as long as the minimum separation distance of 20cm
between the radiating element and the person is maintained and the maximum gain is
less than 2.15dBi.

4.2 Installation Setting
The installation setting must observe the guidelines listed below. Failure to comply with
these guidelines may cause the OMNIDATA device to operate improperly.
• The external antenna must be mounted in a location such that no person will
ever come within 8 inches of the antenna. This is required to comply with FCC
RF hazard regulations.
• The antenna must be installed in such a way that the main radiation pattern
generates vertical polarization. The antenna must conform to guidelines given
in Section 4.5.
• The device should be installed far from any switch mode power supply or
digital switching circuitry.
• The power supply should conform to requirements identified in Section 3.4.
• The device should not be subject to permanent vibrations.
• The device should not be subject to high magnetic fields.
• The device should be mounted in such a way that it makes no contact, or it is
not very close to any metallic object even if that object is connected to the
ground. There should be no other electrical contact to anything other than the
antenna and the flat cable for the power supply and host interface.
4.3 Installation Procedure
Follow the procedure outlined below to install the OMNIDATA device.
1. Install the External Antenna
a. The external antenna assembly consists of the following:
i. Larsen quarter wave antenna – part number SPWH20918
ii. Pasternack Enterprises (PE) SMA male to SMA female
bulkhead cable – part number PE3956-60
iii. 4” x 4” ground plane, aluminum or brass, 0.063 inches thick
b. Select a high, horizontal mounting surface for optimal performance.
The mounting surface must be no thicker than 1/8” (3mm) or problems
with the connector assembly may result.

Document Number: 9400.01484-USG01 Revision 1.6 12/2/2002
plane.
d. Insert the SMA female bulkhead end of the PE cable through the hole
from below.
e. Secure the PE cable to the mounting surface and the ground plane with
a lockwasher and nut (supplied with the cable). Tighten the nut firmly
enough to solidly fix the connector, but take care not to overtighten.
f. Screw the Larsen antenna to the SMA female end of the cable just
installed. Firmly finger tighten. Do not attempt to use any tools to
tighten
2. Install the OMNIDATA Device
a. The OMNIDATA device consists of a single printed circuit board
assembly.
b. Install the OMNIDATA device using appropriate standoffs (e.g. Richco
part number LMSP-4-01).
c. Ensure that sufficient space is available to connect the antenna cabling,
host cabling and power supply cabling. Mechanical drawings of the
OMNIDATA device are shown in Section 3.5 to assist in this process.
d. Attach the SMA male end of the cable installed in step 1 above, to the
SMA female connector on the OMNIDATA device. Tighten the SMA
connector to 8-10 inch-pounds of torque. Over tightening can damage
the connector and reduce the performance of the OMNIDATA device.
3. Install the Host and Power Supply
a. Install the host and power supply. The host must conform to the
following guidelines:
i. The host supports the pin out specified in Table 5.
ii. The power supply must conform to the specifications identified
in Section 2.9.
iii. The host implements a supported host interface protocol (HCI
[2] or CLP [3].) Contact your service provider to determine
which protocol is enabled on your OMNIDATA device.
b. Connect the host and power supply to the OMNIDATA device’s host
interface header.
4. Turn on the Power Supply
a. Follow the instructions in Section 4.4.
4.4 Power-On Procedure
After power has been applied, follow the instructions listed here to verify operation of
the OMNIDATA device. Please refer to the appropriate host interface protocol
document (HCI [2] or CLP [3]) to determine how to execute these instructions.

Document Number: 9400.01484-USG01 Revision 1.6 12/2/2002
1. Query the OMNIDATA device with the host. Verify that the host is able to
communicate with the OMNIDATA device.
2. Periodically poll the OMNIDATA device until the device has registered on the
ReFLEX network for full two-way service.
3. Use the host and OMNIDATA device to send a message to the PIN or email
address associated with the OMNIDATA device being used. Verify that the
message is successfully accepted by the ReFLEX network. Verify that the
message is successfully received by the OMNIDATA device.
4.5 External Antenna Impedance
The OMNIDATA transmitter was designed for a 50 ohms external antenna. The same
antenna is used for transmit and receive, hence the antenna has to work from 901MHz
to 941MHz.
It is possible to connect the external antenna directly to the device or through a coaxial
cable. The external antenna should be mounted close enough to the OMNIDATA unit to
limit the length of the cable and the losses in it. The external antenna assembly must
have a standard male SMA connector.
If the load presented by the external antenna assembly at the SMA port is not 50 ohms,
the output power of the transmitter and the DC current consumption during transmit
time may vary from theirs nominal values. The VSWR of the external antenna assembly
in the transmit band 901 to 902 MHz should be less than 1.7. If the VSWR is greater than
1.7 the transmitter might be permanently damaged. The solution is to have the antenna
re-matched or to impose restrictions on the length of the cable between the external
antenna and the unit. Please contact PerComm for further details.
