FCC REGULATIONS LICENSING The FCC requires you to obtain a station license for your DATAFLOW RTU system before using it, but does not require an operation license or permit The station licensee is responsible for ensuring that the transmrtter power, frequency and deviation are within the limits specified by the station license.

11.1.2 OPTIONAL INTERFACE CABLES, part numbers 06001123 and 06001124, may be purchased for use with the small (S) enclosure. These cables provide the user with 6-foot long, color-coded cables designed specifically for use with DATAFLOW RTU. 11.1.3 INTERFACE CABLE CONNECTIONS: COLOR CODE Ext.
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. At the time of printing this manual, the DATAFLOW RTU firmware supports this pin to be used only as an output.
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 dtilled into the back comers of the case; the holes are tapped with four ( 4) #6- 32 x 3/8 thread-fonning screws.

21.3 Meter excitation voltage may be provided by the DATAFLOW RTU using the Power Out pin of connector JJO I. If the Power Out pin is used as the excitation supply make sure that the maximum current drive of the pin is not exceeded and that your indicator will operate on a supply voltage ofVsupply-5.5Volts.
Using an adjustment tool, adjust RI31 for a deviation of2.80 kHz to 3.00 kHz. 23.2 Refer to the applicable RITRON DTX manual for alignment of the RF board. When using the DTX manual in support of the DATAFLOW RTU only the RF portion is valid. Disregard all references to the DTX control board.
