REMOTE INPUTS/REAR PANEL

TIMEWISE 798A
Remote PARK
The remote
PARK
function allows you to remotely stop counting transducer pulses.
Activating this input is the same as selecting
PARK
on the front panel. As with a front panel
activated park, (or reverse) the
ODOMETER
display will flash every other second when a
remote
PARK
is actuated. However, the beeper will not sound every ten seconds.
The remote
PARK
function is often used when running off-road rallies. During such rallies,
the navigator may use a factor that is a little on the “high” side. The 798A will then
accumulate mileage too fast. The navigator uses this “advance information” to warn the
driver about impending turns or obstacles. The navigator then activates the remote
PARK
input to freeze the odometers until the actual execution point is reached. Releasing remote
PARK
at that point re-aligns the 798A to official course values.
Remote SPLIT
The remote
SP L I T
input splits the clock, main odometer, and calculated time just as does the
front panel
SP L I T
function. The auxiliary odometer and auxiliary calculated time are also
split, and simultaneously reset to zero internally. When remote
SP L I T
is deactivated, all
displays update to current course values, with the auxiliary odometer and auxiliary calculated
time displaying the distance and driving time since the initial activation of remote
SP L I T
.
The remote
SP L I T
input is most often used during rallies that give incremental mileages
between instructions rather than accumulated overall course mileage. Activating the remote
SP L I T
allows you to confirm time and mileage at the execution point of an instruction, while
simultaneously resetting the auxiliary odometer.
Note: The remote
SP L I T
cannot be activated while a front panel
SPLIT
or
CAST
is actuated.
Remote CAST
The remote
CAST
input functions the same as the
CAST
function on the front panel.
Note: The remote
CAST
is inactive while the front panel
CAST
switch is actuated.
The Clock
SYNC input
The
SYNC
input connection allows you to transfer the time of day from a Timewise
checkpoint clock directly into the 798A.
The procedure to synchronize the clock in the 798A is discussed in the
O P E RA T I O N
section
of this manual. See
Automatically Setting the Clock
for details.
Other Rear
Panel
Connectors
The
ODOMETER
INPUT
1
,
ODOMETER
INPUT
2
, and
REMOTE
DISPLAY
modular
jacks are the connectors for the odometer transducers and driver’s module, respectively.
Note: You will not electrically damage either an odometer transducer or the driver’s module
if you accidentally connect them to the wrong modular jack. The 798A is designed to allow
for this mistake.
The
Freq Adj
opening is used when adjusting the 798A clock oscillator. Do not put anything
into this opening.
Appendix D
describes the technical procedure that must be followed to
recalibrate the oscillator in the 798A.
If your 798A is outfitted with option 7 (
Remote AUXILIARY Display Select
), an
additional stereo input jack will be present on the rear panel. This option allows you to
remotely select between two parameters in the driver’s auxiliary display. To alternate
between parameters, all you need to do is open or close an electrical connection between the
“ring” and “sleeve” contacts of the input jack.
