Powering Up the TimeProvider
To power up the TimeProvider, perform one of the following tasks, as appropriate:

Connect the power leads from the power supply (see 

Install the fuse in the fuse panel

Turn on the power supply

LED Indications on Power-up
The LEDs on the IMC, IOC, and TPIU (if present) illuminate in the following sequence:

The LEDs on the TPIU remain off until the Master shelf has completed its power-on 
testing and the GPS input has been enabled. The TPIU and Antenna Power LEDs 
light green and the Antenna Signal LED lights red. When the Master shelf 
completes its power-on testing, the Antenna Signal LED lights green, indicating that 
the TPIU is receiving a valid signal from the antenna.

To log in to the TimeProvider for the first time, you must create a username and 
password using the TL1 commands described below. Once you create a username 
and password, you can connect to the TimeProvider using the SynCraft application 
as described in 

, on page 102, or using the TL1 commands in this 

section.

1. Connect a straight-through DB-9-to-DB-9 serial cable to the local Craft port 

located on the front panel of the IMC or IMC/TPIU card. Connect the other end of 
the cable to a computer.

2. Start a terminal emulation program such as HyperTerminal or ProComm Plus. 

Configure the program for 9600 baud, 8 data bits, No parity, and 1 stop bit, which 
are the TimeProvider’s default communication parameter values.

3. Type 

;

 (semicolon). If the TimeProvider responds with a Deny response, you 

have established communications. If you do not receive the Deny response, 
check the connections, the cable, and the program settings.

Changing the Echo Mode
To view the keystrokes you enter in the terminal emulation program, you need to set 
the Echo mode to Enable. Issue the following command:

ED-EQPT::COML:TS1000::ECHO=ENABLE;

The TimeProvider responds with:
