Serial Solutions Port Settings
Clicking on the Serial Solutions tab will display:
Settings available in this window are:
FIFO Settings.
Enable FIFO - turns the selected ports FIFO buffer on or off. It is strongly
recommended that the FIFO for both ports is left enabled.
Extend FIFO - when checked, extends the selected ports FIFO buffer from 16
to 64 bytes.
Receive Buffer - These settings allow the selection of a receiver FIFO trigger
setting. Selecting a low value will allow the interrupt to be serviced quicker,
which is good for slow machines. If you have a fast machine, setting a high
value will give you more time for multi-tasking operations.
Transmit Buffer - These settings allow the selection of a transmitter FIFO trigger
setting. Selecting a low value will send fewer data-bytes per interrupt, and this is
recommended if you are communicating to a slower machine. Selecting a high
value will send more data-bytes per interrupt, and will give more time for multi-
tasking operations.
485 Mode offers the options:
Half Duplex / Full Duplex(default) - are used in conjunction with the RS485
Multiplex Jumper Settings.
