To change the Baud Rate:
To access the [Baud Rate] option list press
Move the cursor to the required baud rate by pressing
To store selection press . This moves the cursor to [Parity].
4.8.2 PARITY
Parity is a simple method to check the accuracy of an asynchronous serial data transfer. The parity
setting tells the meter how to format the data words it sends to an external device. Parity is usually an
additional bit added to each data word. For example, if you select [EVEN], the total sum of all the bits in
a single data word (including the parity bit) will always be an even number.
The [Parity] option list includes all the standard parity settings for asynchronous serial transmission. The
selected parity must match the parity setting of the receiving external device. Some devices ignore parity
entirely; therefore, the option list includes [None]. The factory setting is [None].
To edit the Parity Setting:
To access the [Parity] option list press
Move the cursor to the required parity setting by pressing
To store the data press . This moves the cursor to [Data Bits].
4.8.3 DATA BITS
You can specify how many data bits the flowmeter uses to format data words for serial transmissions.
The default setting is [7]. Note that the 996P portable printer requires a word length of [8].
To set the Data Word Length:
To access the [Data Bits] option list press
To move the asterisk to the required bit setting press
Press to store data. This moves the cursor to [Line Feed].
4.8.4 LINE FEED
Some serial devices (printers, terminals, etc.) insert a line feed automatically after they receive a car-
riage return character. When communicating with these device types, you should set the Line Feed to
[OFF]. This instructs the flowmeter to send a carriage return character without adding a line feed to avoid
creating an additional blank line after each carriage return. Setting the Line Feed to [ON] tells the flow
computer to insert a line
feed character after each carriage return that it transmits. This may be
necessary to avoid the constant “wrapping” of transmitted data onto a single line. The factory
setting is [NO] (line feed disabled). Note that the 996P portable printer requires [NO].
