ESE/SMPTE Master Clock
When shipped from the factory, the NetWave clock is set for autonomous operation running off an internal
time base. In this condition, the clock time must be set using the three recessed buttons next to the clock in
the console display. For many installations, the console clock is synchronized with an ESE TC-89, ESE TC-90,
or SMPTE master time code signal. A four-pin Molex connector (Figure 6-7), mounted on the console’s rear
panel, connects the time code signal to the console. The Molex connector is internally connected to J4 on the
meter-clock-timer board in the console display.

When a master clock signal is connected, you must set the multi-switch DS4, on the meter-clock-timer
board in the console display, to use the type of master clock signal being received. Setting the DS4 requires
removing the rear cover of the console display (held in place by two or three #1 Phillips screws). With an
ESE master clock, set DS4 switch 2 to ON. The circuit auto-detects which version, TC-89 or TC-90, is being
received.
With a SMPTE master clock connected, set DS4 switch 5 to ON, and leave switch 2 set to OFF. If both
switches 2 and 5 are set to ON, the clock defaults to detect ESE timecode.
Even though the ESE/SMPTE signal input is balanced, an unbalanced signal can also be connected. The
signal polarity must be connected with the + signal connected to pin 1 and ground, or the – signal,
connected to pin 2. Figure 6-8 shows connection details.

Quad A/D Converter
The Harris Broadcast PR&E 4X-A2D (PRE99-1430) can be used to convert four analog signals into four digital
signals to connect four analog signals to the NetWave digital inputs. The 4X-A2D converter, roughly the size
of two decks of cards, is typically mounted below the furniture near the console.
