2.12.1

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 instal­lations 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.

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 Coordi­nated 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.

The ends of an RS-485 transmission line must be termi­nated 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

The standard clock is provided with a 115 VAC 50/60 Hz
wall mount adapter. Units ordered with PS00142, Inter­national 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) com­monly found in the United States and Canada.

Both adapters are terminated with a barrel type connec­tor which plugs into the rear panel DC power jack. Secure
the power connector by installing the cable clamp in­cluded 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.

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 specifi­cally 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

As stated in the previous section, RS-485 Guidelines, a
NetClock or TimeBridge can drive up to 32 devices over
a maximum cable length of 4000 feet. The guidelines
also recommend the RS-485 transmission line be con­nected in a continuous daisy-chain configuration. A
branched or star configuration is not recommended, as
well as long stub lengths to the main transmission line.
If these guidelines present an installation problem, the
RS-485 Repeater output can be used. The Repeater
output regenerates the synchronizing data stream ap­plied to the RS-485 Input/Output terminal block connec­tions. The Repeater output can drive an additional 32
devices over cable lengths up to 4000 feet.

The Repeater output may be used to reduce and simplify
cable runs to devices located in different portions of the
building. Figure 2-8 shows an installation where the
backup dispatch consoles located in the basement re­quires synchronized time.

The TimeView 400 is configurable for computer set op­eration. The computer must have an RS-422/485 inter­face card installed, or an external RS-232 to RS-422/485
adapter to communicate with the clock. The computer
can resynchronize the display as often as every second or
a minimum of every four hours.

To Other Devices

Spectracom offers the TS-1Win program to set the
TimeView 230 and TimeView 400 display clocks from a
Windows 95, 98, NT, ME or 2000 computer.

To enable computer set operation, place DIP switch
number 7 in the ON position. Connect the clock terminal
block to the RS-485 adapter or interface board as shown
in Figure 2-10. If only one clock is connected to the
computer terminal, terminate the RS-485 data bus by
placing DIP switch 10 in the ON position.

The TimeView 400 can be manually set for operation as
a stand-alone display clock. Time is entered using the
rear panel MODE and SET switches. The MODE switch
advances the clock through the setting process and the
SET switch selects the time variables. Depressing and
releasing the SET switch causes the clock to increment
through the time variables. Depressing and holding this
button causes the display to scroll through the time
variables. The setting process sets the hours and min­utes. Seconds are reset to zero at the end of the setting
process.

TimeView 400 cannot be manually set when connected to
an RS-485 data bus. The presence of the RS-485 data
stream disables the MODE and SET switches.

failure could be due to a power failure or the time source

Sequentially flashing hours, minutes and seconds indi­cate that the TimeView 400 is no longer receiving the

Spectracom. Specify Part Number T00058.

The PS00142, International Power Supply, accepts a wide
voltage and line frequency range to allow operation
nearly anywhere in the world. The optional power
adapter is secured to the rear panel of the TimeView 400.
The supplied line cord is compatible with AC receptacles
