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.
