VX User Options
VX consoles are shipped having standard configuration unless specified at time of order. These are ways that the console config-
uration may be varied after manufacture. The items listed are internal options selected by gold jumper links or pcb DIP switches.
DIP switch 'ON' position is down when reading the numbers on the switch body.
Jumper link default is marked with a line on the board and is usually pins 1&2 of the three pin header.
In addition there are links for module function assignment. Take care to not disturb these when using USER OPTION links.
