Software/ Programming
4.2.1 The AC Power Supply, RITRON part number RTC-PAS, converts 110 Volts AC to a DC
voltage for use by the
DATAFLOW
RTU.
The power supply provides power to the RTU
when RTU programming software is being used, and also provides power to the RTU, if it
is to be connected to a MODBUS PC controller.
CAUTION:
Plug the power supply only into a 110 VAC outlet.
AC Power Supply, RITRON
part number RPS-I is
intended
only for indoor use at nonnal room temperatures. It
is
not intended
to provide protection from water or any other contaminants; it is
not intended
to function over the full temperature range of the
DATAFLOW RTU.
To correctly use the power supply, plug the two-pronged end into a 110 V AC 50-
60 Hz wall outlet. Plug the 2.1 mm power jack into the 2.1 mm power receptacle of
the RTU-PCPC cable.
NOTE:
The AC Power Supply furnished with the programming kit is not guaranteed to
provide adequate current to the RTU in HIGH (SW) power mode. When the
transceiver is operating in the HIGH power mode, DC power supply of 12 Volts and
2.5 Amps minimum is required. For external power supply connection, mate the
coaxial power connector of the RTU-PCPC cable to a coaxial power connector,
Radio Shack part number 274-1569 or equivalent, having an outer diameter of
5.5 mm and an inner diameter of 2.1 mm.
4.2.2 The Computer Cable, RITRON part number 9/RTC-PAS, connects the 25-pin
PC-compatible COM port to the RTU-PCPC cable. Plug the 25-pin connector into the
computer port and the modular telephone jack into the RTU-PCPC.
CAUTION:
Computer Cable, RITRON part number RTC-PAS is
intended
to operate at nonnal
room temperatures; it is
not intended
to function over the full temperature range of
the
DATAFLOW RTU.
NOTE:
If the COM port has a 9-pin connector, a 9-pin to 25-pin serial port adapter is
required. The adapter is not included with the programming kit.
4.2.3
DATAFLOW RTU
Cable, RITRON part number RTU-PCPC is used to connect the RTU
to the power supply and the computer cable. Plug the 7-pin circular connector of the RTU
PCPC into the 7-pin connector of the R TU.
CAUTION:
DATAFWW RTU
Cable, RITRON part number RTU-PCPC is
intended
to operate at
normal room temperatures, it is
not intended
to function over the full temperature range
of the
DATAFLOW RTU.
