Remote Operation
The 25-pin rear-panel REMOTE connector is a subminiature
D -type connector. It accepts the input for RGB/YRGB stair-
case, external horizontal, remote sync external blanking, time
code, and Left and Right audio. TTL signal or ground clo-
sure to designated pins will enable Staircase, External Hori-
zontal, or Remote Sync displays.
When Remote Sync is enabled, the on-screen TIME/DIV. read-
out is not present. When Remote Sync or External Horizon-
tal is enabled with timing cursors, “
UNCAL ” is displayed in
place of a quantitative readout.
The REMOTE connector is configured for Staircase (RGB or
YRGB) or External Horizontal input through the CONFIGURE
menu, shown on page 3-18.
The user can store and recall up to eight front-panel setups
through the remote. Remote connector pin assignments and
an operational description begin on page B-1.
Using Presets through the Remote
The 1740A/ 1750A--Series has 10 presets capable of storing
front-panel setups. Presets one through eight are accessible
through the rear-panel
REMOTE connector. A TTL low or
ground closure on one of the PRESET pins selects the front-
panel setup stored at that preset location.
When STORE (pin 25) is grounded along with one of the pre-
set pins, the current front-panel setup is stored at the selected
preset location.
