To change the Baud Rate:
To access the [Baud Rate] option list press the <Right Arrow>.
Move the cursor to the required baud rate by pressing the <Up/Down Arrow>.
To store selection press ENTER>. This moves the cursor to [Parity].

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 the <Right Arrow>.
Move the cursor to the required parity setting by pressing the <Up/Down Arrow>.
To store the data press <ENTER>. This moves the cursor to [Data Bits].

Data Bits

You can specify how many data bits the meter 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 the <Right Arrow>.
To move the asterisk to the required bit setting press the <Up/Down Arrow>.
Press <ENTER> to store data. This moves the cursor to [Line Feed].

Line Feed

Some serial devices (printers, terminals, etc.) insert a line feed automatically after they receive a
carriage return character. When communicating with these device types, you should set the [Line
Feed] menu cell to [OFF]. This instructs the flow computer 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].
