The rear-panel REMOTE connector is a subminiature 15-pin D-type receptacle
with female contacts. All of the active remote control lines can be forced low by
remote ground closures or TTL levels.
The THREE Line or Field REMOTE input provides a Three Line/Field parade
display. No staircase signal is required to produce the parade display. One, two,
or three video signals can be input.
Pin assignments for the REMOTE connector are shown in Figure 1–2 and
Table 1–2.

/EXT Horizontal Enable Low = RGB Enable or EXT Horizontal Enable (EXT Horizontal selected by front-panel
MENU selection). Level sensitive, allowing instrument to recognize RGB or External
Horizontal display modes during power-up. Low level routes the signal on pin 10 to the
Horizontal amplifier, where it is added to the ramps from the Ramp Generator.
In RGB mode (selected by A3J6), ramp generator reduces the ramp to 1/3 or 1/4 size. If
External Horizontal is turned on (via the MENU), the ramp generators will not run at all.
This is the only difference between RGB and External Horizontal.
/ A slanted line before a control line name indicates an active low.
