The TimeView 400 is configurable for computer set op-
eration. The computer must have an RS-422/485 inter-
face 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.
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.
