VM700A Option 01 (NTSC) & Option 11 (PAL) User Manual

Consider the following lines from a user-generated Timed Events file named

“daily_events”:

Timed Events File: daily_events

Time Channel Type Selected File Name

9:30 B function mid_morn

15:30 B report mid_pm

Timed Events files use a 24-hour clock to specify event occurrences. When this

file is the current Timed Events file, the following events are set to occur daily:

1. A function called “mid_morn” is executed at 9:30 a.m., and

2. A report is generated at 3:30 p.m., using the Video Source file named

“mid_pm.”

Two kinds of timed events can occur: a report can be generated (designated as

event type “report” in the Timed Events file), or a function can be executed

(designated as event type “function” in the Timed Events file). For “report”

events, the VM700A looks in the /nvram0/ConfigFiles/ Video_Source~Files

directory for the file named in the Timed Events file.

For “function” events, the VM700A looks for the function named in the Timed

Events file in directory /nvram0/FunctionKeys/Timed~Functions. The function

selected as a Timed function must reside in the Timed~Functions subdirectory

(displayed by the Function Keys soft key in the Configure menu). The

parameters for the Auto report (selected measurement limits, measurement

locations, etc.) are specified by the selected file in the Source_Selection~Video

file.

When a report time occurs, the VM700A screen shows the Timed Report display

(unless the VM700A is in remote mode; see note below). The Timed Report

display includes a status line showing the channel and the Selected Measure-

ments file in use, a soft key labeled Cancel Report, and the measurements being

made. Pressing the Cancel Report soft key halts the timed report execution.

Once the report is complete, the VM700A returns to the mode it was in when the

report began. The Copy button flashes until the report is either printed or

canceled with the Cancel Copy soft key in the initial Configure menu.

When a function time occurs, the VM700A executes the function. When the

function has been executed, the VM700A remains in the state specified by the

body of the function; it does not return to the state it was in when function

execution began.

NOTE. If the VM700A is in remote mode during a scheduled timed event, the

scheduled event is not performed.
