Power-Up
To power the TimeSource 3000, follow the steps in Procedure F. Before starting this
procedure, be sure the antenna, shelf, and all connections appropriate for this installation
have been installed, and that the host computer is set to communicate with the TimeSource
3000.
Procedure F. Power-Up
Step Procedure
Test Equipment:
• Groundin g wrist strap
• Digital multimeter (Fluke 77 or equivalent)
• Laptop computer with communications software (e.g., Windows Hyperterminal, ProComm Plus,
CrossTalk)
1 On the computer connected to the TimeSource 3000, start a VT100 terminal mode session
via communication software that supports the Y-modem protocol (such as Hyperterminal, or
a commercial package such as PROCOMM PLUS or CrossTalk).
2 On the computer connected to the TimeSource 3000, set the communication software to
communicate with the port that is connected to the TimeSource3000.
3 On the computer connected to the TimeSource 3000, set the RS-232 communication
parameters to 8 data bits, no parity bit, 1 stop bit, and 9600 baud.
4 On the computer connected to the TimeSource 3000, connect the computer communication
p
ort to the COM1, COM2, or Craft port on the TimeSource 3000. A craft port-to-PC
communication cable is provided in the hardware kit for this purpose.
5 Ensure that the TimeSource 3000 plug-in card is not installed in the shelf.
6 Ensure that all fuses that supply power to the TimeSource 3000 Shelf are removed from the
fuse panel.
7 At the shelf end of the battery leads, use the multimeter to measure the voltage between the
following:
Test Point Test Point Result
–48V A lead –48V B lead 0 V
–48V A lead TB1: RTN A 0 V
–48V A lead TB1: FRM 0 V
–48V B lead TB2: RTN B 0 V
–48V B lead TB2: FRM 0 V
8 Attach a grounding wrist strap to the wrist, and plug the other end into the ground jack at the
upper-right corner of the front of the plug-in card.
9 Pull out the latching levers at each end of the front panel of the TimeSource 3000 card so
that the levers are pointing directly out from the front panel.
10 Push the card into the shelf until the latching levers begin to move in.
