Front panel pushbuttons
[a]
[a] The ON/OFF status of the pushbutton LEDs indicates which cable wire or pin on the rear panel connector is grounded. As an example, if
ATTENUATOR X pushbutton 3 is illuminated, pin 10 of the ATTEN X connector (blue wire from cable) is grounded and pin 9 floats at a high
impedance. For solid state switches (P and U series switches), pin 3 is NC (No connected), pin 4 is connected to -5V, regardless of
whether pushbuttons 9 and 0 LEDs are ON or OFF.
Vcc will auto reset to 5V and TTL mode will automatically turn on for rear panel connector pins 5, 7, 9 and 11.
