The Spectracom®Model 8177 TimeView 400, shown in
Figure 1-1, is a synchronized display clock. TimeView 400
features 4.0 inch LED digits which can be viewed from 150
feet away. The clock displays traceable time when con-
nected to a Spectracom NetClock®Master Clock. The
display is configurable for 12- or 24-hour time format and
time zone offsets.
TimeView 400 displays may also synchronize to a host
computer running a network timekeeping system, or
manually set for stand-alone operation.

MOUNTING INSTRUCTIONS
The ancillary kit includes screws and plastic anchors for
wall mounting the clock. Tools needed for mounting are
a Phillips screwdriver, a ruler, and a 1/4" drill.
TimeView is designed to mount over a duplex outlet to
conceal the power adapter and data cables. For instal-
lations where this is not possible, notches are provided
along the top and bottom edges for routing power and
data cables.
To install TimeView over a duplex outlet, lay a reference
line over the cover plate as shown in Figure 2-1.
To provide clearance for the PS00142 International Power
Supply, locate the left mounting hole 12 inches from the
center of the outlet. Locate the right mounting hole 4
inches from the center of the outlet.

Time Zone Offset
The time zone offset feature allows clocks synchronized
to a NetClock or computer to display time in alternate
time zones. The selected time zone offset value is
subtracted from the applied input data stream. DIP
switches 1 through 5 enter the binary equivalent of the
offset value of 0 to 23. Table 2-1 lists common offset
values from a Greenwich Mean Time (GMT) or Coordi-
nated Universal Time (UTC) source during periods of
Standard time and Daylight Saving Time. Table 2-2 lists
the DIP switch settings for the offset values shown in
Table 2-1. See Section 3.2.4 for a complete list of offset
and switch settings.

Termination
The ends of an RS-485 transmission line must be termi-
nated to preserve the signal waveform and prevent
reflections. The TimeView 400 termination switch, DIP
switch 10, terminates the RS-485 data bus into 120 ohms.
Place switch 10 in the ON position when the clock is
installed at the end of the RS-485 data bus. Otherwise,
place this switch in the OFF position. Refer to Section 2.4
for additional information on termination.

The standard clock is provided with a 115 VAC 50/60 Hz
wall mount adapter. Units ordered with PS00142, Inter-
national Power Supply, are equipped with a 90 to 240
VAC, 47/63 Hz power adapter mounted to the rear panel.
The international power adapter is shipped with a line
cord compatible with AC receptacles (NEMA 5-15R) com-
monly found in the United States and Canada.
Both adapters are terminated with a barrel type connec-
tor which plugs into the rear panel DC power jack. Secure
the power connector by installing the cable clamp in-
cluded in the ancillary kit as shown in Figure 2-2. Secure
the PS00142 power adapter ground lead to the clock
chassis using the supplied hardware.

BackgroundBackground
BackgroundBackground
Background: RS-485 is a balanced differential transmis-
sion that offers exceptional noise immunity and cable
lengths up to 4000 feet using twisted pair cable.
Cable selectionCable selection
Cable selectionCable selection
Cable selection: Low capacitance, shielded twisted pair
cable is recommended in installations where the RS-485
cable length is expected to exceed 1500 feet. Table 2-3
suggests some manufacturers and part numbers
for extended distance cables. These cables are specifi-
cally designed for RS-422 or RS-485 applications; they
have a braided copper shield, nominal impedance of 120
ohms, and a capacitance of 12 to 16 picofarads per foot.
RS-485 cable may be purchased from Spectracom. Specify
part number CW04xxx, where xxx equals the length in
feet.
