2.2.2 12- or 24-Hour Display The TimeView 230 can display time in a 12- or 24-hour format. Place DIP switch 6 in the ON position for 12-hour display format and OFF for 24-hour time display. 2.2.3 Synchronization Source DIP switch number 7 selects the source of the synchronizing data stream.
Page 15: Synchronization Connection
Model 8186, TimeBridge, Wireless Time Link Model 8189, NetClock/NTP, GPS Network Time Provider The TimeView 230 connects to the RS-485 output port found on the NetClock Master Clocks and TimeBridge. These ports provide a continuous once-per-second time data stream. The TimeView 230 automatically detects the data format and baud rate of the synchronizing data stream.

TimeBridge All Spectracom GPS synchronized clocks and Model 8186 TimeBridge provide the RS-485 synchronizing data stream on a 3-position terminal block. Connect the TimeView 230 to the time source as shown in Figure 2-4. FIGURE 2-4 GPS MASTER CLOCK AND...
Page 17: Interconnection Information
The mating terminal blocks are provided in the equipment ancillary kits. NOTE: The TimeView 230 accepts only Format 0 or Format 1 data streams. Configure the RS-485 output port on the NetClock or TimeBridge to provide Format 0 or Format 1.
Page 18 TABLE 2-3 CABLE SOURCES FOR RS-485 LINES OVER 1500 FEET For cable runs less than 1500 feet, a lower-cost twisted pair cable may be used. Refer to Table 2-4 for possible sources. NOTE: CAT5 Network cable may also be used for cable runs less than 1500 feet.
Page 19 (Figure 2-6) terminate the devices installed on the extreme ends of the bus. The TimeView 230 includes a built-in termination switch that places a 120-ohm termination resistor across the RS-485 line. Place DIP switch number 10 in the ON position when the TimeView 400 is located at the end of the time data bus.

GROUND RS-422/485 INTERFACE FIGURE 2-9 COMPUTER CONNECTION Multiple TimeView 230 clocks can be synchronized by a single computer when connected as shown in Figure 2-10. Terminate the last clock in the line by placing DIP switch 10 in the ON position.
Page 26: Manual Set Procedure
The computer can synchronize up to 32 clocks over a total cable length of 4000 feet. MANUAL SET PROCEDURE The TimeView 230 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.
Page 27 Hours are entered in a 24-hour format, even if the 12-hour display format is selected. For example, when setting the TimeView 230 for 2:00 PM, enter 14 for the hours value. To set hours, depress and release the MODE switch. The hours digits blink and show the current hours value.
Page 28 2.6.1.3 Set Seconds The seconds digits blink and display the current seconds value. If the value is appropriate, depress the MODE switch to exit from the Manual Set procedure. Seconds are not selected like the hours and minutes values. Depressing the SET button resets the seconds to "00"...
Page 29: Section 3 Operation
OPERATION INTRODUCTION This section describes the TimeView 230 display, rear panel functions, and computer setting information. DISPLAY TimeView 230 Display, shown in Figure 3-1, features green 2.3 inch digits for the hours and minutes, and 1.0 inch digits for the seconds. Display brightness is adjustable to suit various lighting conditions.
Page 30: Fault Indications
RS-485 driver/receiver failure. The display will continue to flash until the data stream is restored. Computer Fault Indications The display seconds flash when the TimeView 230 has not received a synchronizing data stream from the computer within four hours. The seconds remain flashing until the computer updates the clock.

2 and 3 of the terminal block. Connect the non-inverted RS-485 data line to Pin 1, the inverted data line to Pin 2, and the cable shield to Pin 3. TimeView 230 accepts either Data Format 0 or 1 at baud rates from 300 to 9600 from a NetClock or 9600 baud from a computer.
Page 33: Manual Set Switches
3.2.3 Power The TimeView 230 is powered by the supplied 115 VAC to 16.5 VAC power adapter. The power jack accepts a barrel- type plug with a 5.5 mm O.D. and a 2.1 mm I.D. Replacement adapters are available from Spectracom. Specify Part Num- ber T00054.
Page 34 Switches 1 through 5 Time Zone Offset The TimeView 230 can offset the time received from a NetClock or computer to display time in other time zones. DIP switches 1 through 5 enter the binary equi-valent of the offset value between 0 and 23.
