See the previous page's "emulating special keys in the preamble" section.
A final use of the Preamble/Postamble is to enter a minimum/maximum length check for bar code data read. Use the Preamble or Postamble by entering nnmm where "" is ASCII 124, "nn" is the two digit minimum to be read and "mm" is the two digit maximum to be read.

Timing does not apply to Mac ADB or any USB attachment.
Before trying this, try the "learned timing" discussed on page 12.
For Computer Interfaces 0,1,and 2, the WDP Reader can transmit bar code data at five different rates. Most computers work at the fastest speed ("None"), but some systems require slower rates. Try the "None" setting, and (when you're done configuring it) try reading some codes. If you get partial or garbled reads, try other timing settings to solve the problem. (The Mac needs no timing adjustments.) Try each timing rate (fast to slow); don't assume that if the slowest and fastest don't work, the intermediate settings won't either. After each failing attempt at timing setting, type "12" in the upper keyboard row to be sure the keyboard has not been locked or confused; if the "12" doesn't type correctly, reboot before trying a new timing setting.
Reset
Don't scan Reset unless you're sure you want to restore the WDP Reader to its default settings (as described on page 7), erasing all changes you've made, because that's exactly what Reset will do.
