• The highlighted items on the display are the parameters that are currently
set.
• The PARITY parameter is flashing because it is selected.
4. Use the
K and L cursor keys to change the selected parameter on the display.
5. Use the
H and J cursor keys to change the highlighted setting of the
currently selected parameter.

About communications parameters...
Communications parameters make it possible for two communicating units to
understand each other. The following explanations are provided for your informa-
tion only. The only thing you need to remember is that the parameters of the send
unit and the receive unit must be identical. Otherwise you will not be able to
transfer data successfully.
PARITY
Parity is used for error detection during data exchanges. You can set the SF Unit
parity as even (E), odd (O), or none (N).
BIT LENGTH
The bit length parameter states how many bits are to be used for each character.
You can set the SF Unit bit length as 7 bits or 8 bits.
BPS
The letters “BPS” stand for “bits per second,” and this setting represents
the speed at which data is sent. The SF Unit lets you set a speed of either 4800
or 9600.
