Programming the Second Character
The second character comes programmed as the ASCII STX
character (decimal 2). You can change this to any 8-bit character
you wish by reprogramming dipswitch “SW2”. “SW2” is an eight-
position switch with each position equal to a certain weight. Refer to
“Setup” for instructions on removing the cover to access “SW2”.
Table 4 shows the weight chart for “SW2”.
*
Factory Default -- ASCII “STX” character
(decimal 2), SW2 position 2 is only one ON.
If you wish to use the letter "U" as the second character, which
has a decimal value of 85, you would turn on switches 1, 3, 5, and 7
(1 + 4 + 16 + 64 = 85). Caution should be used when selecting the
second character, so that by itself, or with the ESC character in front
of it, it is not a valid command to any of the devices on the port. For
instance, on some printers ESC @ is the reset command. If you
tried to use the @ symbol (decimal 64) for the second character you
could reset your printer every time the preamble code was sent.
Also, if your communication configuration is set for 7 data bits you
cannot use the eighth bit of SW2. For a list of the ASCII character
codes and their decimal values, refer to Appendix A.
Binary File Transfer
A simple method of using the Mini Smart Switch to transfer
binary files without the concern of it accidentally disconnecting, is to
set the file transfer at a different baud rate from the rate of the Mini
Smart Switch. When transferring files at a different baud rate, the
Mini Smart Switch will stay connected from the last preamble code.
