OWNER INFORMATION

FCC REGULATIONS

LICENSING

The FCC requires you to obtain a station license for your DATAFLOW RT U system before using it, but does not require an
operation license or permit.

The station licensee is responsible for ensuring that the transmitter power, frequency and deviation are within the limits
specified by the station license. The licensee is also responsible for the proper operation and maintenance of the radio
equipment. This includes checking the transmitter frequency and deviation periodically, using appropriate methods.

You will need to obtain a FCC license to operate the DATAFLOW RT U. To get a FCC license for VHF or UHF frequencies,
submit FCC application Form 600.

SAFETY STANDARDS

The FCC (with its action in General Docket 79-144, March 13, 1985), has adopted a safety standard for human exposure to
radio frequency electromagnetic energy emitted by FCC regulated equipment. OMEGA observes these guidelines, and
recommends that you do also:

• DO NOT hold the DATAFLOW RTU so the antenna is very close to or touching exposed parts of the body,

especially the face or eyes, while transmitting.

• DO NOT operate radio equipment near electrical blasting caps or in an explosive atmosphere.

• DO NOT allow children to play with any radio equipment that contains a transmitting device.

REPAIR of OMEGA products should be performed only by OMEGA authorized personnel.

DATAFLOW RTU

1. INTRODUCTION

1.1 The DATAFLOW RTU from OMEGA is a complete wireless telemetry system designed to
deliver industrial instrumentation signals from a source to other instruments via radio frequency
communications. The DATAFLOW RTU allows you to access industrial measuring devices in
remote locations without running wires, installing microwave links or leasing a telephone line.
OMEGA DATAFLOW RTU and MODBUS radio communications equipment replaces these
methods.

1.2 Manual Part A is intended to provide information needed for the installation and operation of
DATAFLOW RTU systems. The intended readers are people familiar with industrial
instrumentation. A basic understanding of radio communications is helpful. The included
information is valid only for models listed on the cover.

12. HARDWARE CONFIGURATION

12.1 The DATAFLOW RTU has six hardware configurable jumpers. Jumper functions are described in the
following paragraphs 12.1.1 to 12.1.6. See Figure A2, page A-6, for location references.

12.1.1 PJ101 (Y 2.8 - X 2.0): This jumper setting determines whether configurable I/O 1 is an input or an analog
output. The jumper across pins 1 and 2 configures the pin to be an input. The jumper across pins 2 and 3
configures the pin to be an output, the default setting.

12.1.2 PJ102 (Y 2.8 - X 1.8): This jumper setting determines if configurable I/O 2 is an input or an analog
output. The jumper across pins 1 and 2 configures the pin to be an input. The jumper across pins 2 and 3
configures the pin to be an output, the default setting.

12.1.3 PJ103 (Y 2.8 - X 1.6): This jumper setting determines how the configurable analog outputs 1 and 2 are
powered. The jumper setting is valid only if PJ101 or PJ102 is set for output. The jumper across pins 2
and 3 configures the output to be powered by system power. The jumper across pins 1 and 2 configures
the output to be powered by regulated radio power, the default setting.

PJ104 (Y 2.9 - X 1.2): This jumper setting determines if configurable I/O 1 is set for voltage or current loop

analog output. This jumper setting is valid only if PJ101 is set for output. With one jumper across pins 1
and 2 and another jumper across pins 3 and 4, the output is configured for voltage, the default setting.
Only one jumper across pins 2 and 3 configures the output for current loop.

( A-11 )

Installation/Operation

12.1.5 PJ105 (Y 2.7 - X 1.2): This jumper setting determines if configurable I/O 2 is set for voltage or current
loop analog output. This jumper setting is valid only if PJ102 is set for output. With one jumper across
pins 1 and 2 and another jumper across pins 3 and 4, the output is configured for voltage, the default
setting. Only one jumper across pins 2 and 3 configures the output for current loop.

12.1.6

PJ106 (Y 0.2 - X 2.9): This jumper connects the internal battery power to the power input of the control
board. This jumper setting is valid only when using the internal battery power. With the jumper installed,
the default condition, the internal battery is always connected to control board power, meaning the unit is
always ON with the internal batteries installed.

13. SOFTWARE CONFIGURATION

13.1 All DATAFLOW RTUs contain identical hardware; the software configuration of a unit makes it perform a
particular task. This programmable configuration can be changed using any PC compatible computer,
DATAFLOW RTU Programming Software and a DATAFLOW RTU Programming Cable.

14. MOUNTING INFORMATION

14.1 To provide DATAFLOW RTU with an aluminum enclosure, it may be purchased with the small enclosure
(S). The S enclosure has four pilot holes drilled into the back corners of the case; the holes are tapped
with four (4) #6 - 32 x 3/8 thread-forming screws. The DATAFLOW RTU is shipped with these screws
installed in the case. A T-15 Torx© drive tool is required to remove the screws.

14.1.1 You can use the holes in the back of the enclosure to mount the DATAFLOW RTU directly to a surface,
using the recommended hole pattern shown in Figure A4. The four thread-forming screws can be used to
secure the case to the surface, if desired, by removing the screws and reusing them. Alternately, four #6 ­32 machine screws may be used; ensure they do not extend more than 5/16" into the case.

14.1.2 Optional mounting bracket OMEGA part number RTU-25104600 is available for DATAFLOW RTU. To
install this bracket to the case, remove and save the four thread-forming screws described in paragraph

14.1 to attach the mounting bracket to the case. Be sure the narrow portion of the keyhole is positioned
towards the top (UHF antenna connector) of the DATAFLOW RTU. Use the recommended hole pattern
for the optional mounting bracket shown in Figure A5.

14.2 Reassembling DATAFLOW RTU Cover/ Waterproofing the Antenna Connection

14.2.1 The DATAFLOW RTU is weather-resistant if it has been properly sealed. If you have opened or

disassembled the device, refer to the following instructions.

14.2.2 Sealing the Housing Cover: Inspect the seal and mating surfaces for flaws (tears, gaps, dents, etc.).

Repair the surface or replace the part as necessary. Purchase replacement cover gaskets through Omega: Part
No. RTU-25605100.

Insert the seal in the cover. Thread the four (4) screws through the cover, into the housing; do not tighten the
screws. Snug down the screws in an X sequence; i.e.: top left, then bottom right, then top right, then bottom
left. Then fully tighten the screws in this same sequence.

14.2.3 Replacing Connectors: OMEGA discourages the practice of removing and discarding the protective cap

from the connectors. Doing this may reduce the water-resistance of the unit. If you must remove a connector for
any reason, make sure it has been retightened properly  finger-tight connector nuts will not provide an
effective water barrier.

14.2.4 Connecting the Antenna: Seal screws are used to secure the antenna to the housing. Always replace

with a new seal screw, not a common screw.

Do not remove the antenna connector from the housing; doing so will destroy the silicone rubber seal in the

interface. The screw securing the ground strap inside the housing must be fully tight.

14.2.5 If this device is to be used in a wet environment, use seal tape around the antenna connection. Use

Archer Connector Sealant, Radio Shack Number 278-1645 or an equivalent. Wrap the connection with the
sealant tape and press it securely in place.
