Binary File Transfer
A simple method of using the Smart Switch to transfer binary
files without the concern of it accidentally disconnecting, is to set the
file transfer at a baud rate different from the baud rate of the Smart
Switch. When transferring files at a different baud rate, the Smart
Switch will stay connected from the last command control string.
Port Select Test
The 232XSSD4 has a built-in port select test. Placing DIP
switch 1 (SW1) position 8 in the on position and powering up the
232XSSD4 starts this test. Refer to Figure 2. It will test the port
selection, port expansion, and address circuits for all sixty-eight
ports. When the test is started each port will be individually turned
on for one second, starting with port A on the 232XSSD4 and ending
with port D at address fifteen for a total test time of sixty-eight
seconds. Once the last port has been turned off the test will start
over and continue looping until SW1 position 8 is placed in the off
position, at which time the Smart Switch will begin normal operation.
This test is can be used to verify address settings of the port
expander modules.
