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 6 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. Note also that 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 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 preamble code.
