2-22 Configuring Your RS-232 ASCII Module
Setting Up the Transmit Character Buffer Length
The Transmit Character Buffer Length is the number of characters that
the 1734-232ASC module can receive in its transmit buffer from the
DeviceNet network. This size contributes to the I/O’s consume size.
This size can be found in the Parameter object.
Setting Up and Using the Transmit Delimiter
The Transmit Delimiter is an end-of-string character that determines
how many bytes to transmit over the serial link to your ASCII device.
The 1734-232ASC module will transmit up to and (optionally)
including the delimiter when the above condition is met. The Transmit
Delimiter can be set to any valid binary value. Be careful not to set the
delimiter to a value outside of the valid range for your data bits. (A
data bit size setting of 7 will only allow you a delimiter range of 0-127
dec., 00-7F
hex.)
If the length is 0 and if you do not have a valid delimiter in your
string, the module will send all data characters from the I/O field to
your serial device
.
IMPORTANT
This Transmit Delimiter will be used only if the
length is 0. If this length is not 0, the 1734-232ASC
module will ignore the transmit delimiter and will
send the define number of characters.
