However, if you have the latest firmware and software, you'll notice that there's a 'Duration' setting on the IR window which contains Option Buttons for 'Default' or a specified time value. What you may want to try is to create keypad buttons 0-9 and use the Default duration, then create a second set of keypad buttons to use for the 1's digit where 10's digit follows. On each of these buttons, set the Duration to something like 0.5 seconds or whatever your equipment requires to do the job.
