7.1.8 Changing Communications Parameters
On occasion, you might need to change the parameters by which the PT878GC communicates with a PC over the
wireless infrared interface. To check or change these parameters:
1. From the Meter menu, scroll to the Communications entry and press [ENTER] . The Communications window
appears similar to Figure 108 below.
Figure 108: The Communications Window
2. The first prompt asks for the node identification number, which can be any number from 1 to 240.
IMPORTANT: Do NOT change the node ID unless instructed by Panametrics Sensing.
a.
Press
[ENTER]
to open the text box.
b. Use the numeric keys to enter the node ID.
c. Press [ENTER] to confirm the entry.
3. The next prompt asks you to select the communications interface from two options: IrDA (Infrared Data
Association) and the IR232 virtual interface. You must use IrDA when using an IR printer or transfer application
such as QuickBeam. Use the [

] and [

] keys to scroll to the desired selection, and press [ENTER] .
Note: For more information on loading software updates via the infrared interface, see Chapter 9, Servicing the
PT878GC .
If you have selected IrDA, you have completed entering data in this window. However, if you have selected IR232, the
PT878GC asks for four more parameters.
IMPORTANT: Using IR232 requires the following parameters:
• Baud Rate -- 9600
• Parity -- None
• Stop Bits -- 1
• Data Bits -- 8
4. The program now asks for the baud rate. The default rate is 9,600 bps.
a.
Press
[ENTER]
to open the drop-down menu.
b. Use the [

] or [

] arrow keys to scroll to the desired rate, from 300 to 115.2K bps.
c. Press [ENTER] to confirm the entry.
5. The next prompt asks for the parity from five options: None, Mark, Space, Even or Odd. The default parity is None.
