Vend Duration:
This is used to program the length of time that the HTK turns on its vend relays. The
vend relays are turned on to signal the receiving equipment as if an operator was pressing a button on a
keypad. The length of time these relays should be held depends on the requirements of the receiving
equipment. It should be the same amount of time a person would take to press and hold the button.
*Refer to the your equipment manual before programming these settings
