CHAPTER THREE
3.7.13 SELECTING ID (OR DAYS)
The Generator Outputs Menu, Figure 3.7.12.2, permits selection of the ID mode for the
Generator. This selection allows the user to utilize the Days portion of the display, and in the
Code Output, as a three digit ID (Identification Number). When ID has been set to ON, on will
be in upper case letters and off will be in lower case letters. With ID “ON”, days are not updated
at midnight rollover. Normally ID is OFF.
To enter an ID Number, use Inputting Time as described in paragraph 3.7.8 to enter the desired
ID Number in the Days portion.
3.7.14 SELECTING LS (LEAP SECONDS)
The Select Generator Outputs Menu provides a method of setting Leap Seconds as either ON or
OFF. Setting Leap Second (LS) “ON” any time within 24 hours prior to midnight will
automatically add 1 Second to the Day, at midnight, and will then set itself to “OFF”
“ON” or “OFF” being in upper case letters designates the current mode selection of the function.
3.7.15
SELECTING GENERATOR SPEED-UP (MULTI-CODE SERIAL ENCODER)
Selecting “SPEEDUP” from the Select Generator Outputs Menu, Figure 3.7.12.2, will allow the
generator speed-up rate to be selected as shown in Figure 3.7.15.1 below:
Select Generator Speed-Up Menu
Figure 3.7.15.1
Select Desired Generator Speed up
X1 X2 X4 X8 X16 X32 X64
The SPEED UP menu relates to the generator only. When sped up, most generator functions are
inhibited (including the parallel outputs, video time insertion and J10 & J11 serial code output).
START, STOP and time PRESET are preserved. If the unit is switched to Translate while the
Generator is sped up, the Generator speed is automatically switched to 1:1 (real time). The
allowable generator speed up is dependent on the time code being generated. IRIG G will
function up to a 4:1 increase, while all other codes will work properly from 1:1 up to 32:1. The
32:1 speed is about one percent fast. The generator speed must be manually returned to 1:1 in
order for the re/generate function to work correctly. Merely switching to the Translate mode will
not assure proper regenerate operation.
NOTE
Following a change in selected code output or speed up (greater than 1:1 only) up to 100 seconds
of code time may be required before the outputs are stable. Switching to a 1:1 (real time) speed
will produce correct outputs immediately.
