8 Transport® Model PT878 Portable Liquid Flowmeter User’s Manual
2.1.3 Input/Output Connections (cont.)
2.1.4 The Infrared Wireless Interface
The PT878 comes equipped with an internal infrared transceiver (shown in
Figure 2 on page 6) that enables communication between the meter and
other IR devices, particularly the IR ports or dongles (IR to RS232 adapters)
of Windows
®
-based PCs. Users can send and receive site and log data.
They can also program the meter using the optional PanaView software
interface. The PT878 was designed for use with products that comply to the
IrDA protocol. For more information on establishing IR communications
between the PT878 and your PC, refer to Appendix F.
Note: The dongle connection is RS232. The configuration options are either
RS232 or IRDa. Selecting the RS232 does not
link the meter to the
dongle. IrDa must be selected for the link to work.
