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.
