Step
Activity
1.
With the power to the FIREBERD 4000 turned off, insert the RS-449/530/MIL Data Interface in the designated
rear-panel slot.
2.
Press the POWER switch to apply power to the FIREBERD 4000.
RESULT:
The SETUP display shows the units current configuration.
If the FIREBERD 4000 is in Self-Loop mode after power-up, disengage the SELF LOOP switch.
3.
Set the SETUP CATEGORY switch to the INTERFACE category.
4.
Using the SETUP SELECT switch and the softkeys underneath the SETUP display, configure the INTERFACE
SETUP menu as follows:
NOTE:
Unless indicated, press the right half of the SETUP SELECT switch once between selections.
Select:
1.
MIL449 to select the RS-449/530/MIL Interface.
2.
188C to select the type of interface.
3.
DTE to select DTE emulation.
4.
ASYNC to select asynchronous timing.
5.
DATA BITS as required (5, 6, 7, or 8).
6.
PARITY as required (ODD, EVEN, or NONE).
7.
STOP BITS as required (1, 1.5, or 2).
8.
Select LL (Local Loop) or RL (Remote Loop) ON or OFF depending on the test.
9.
ON to select Signaling positive.
5.
Set the SETUP CATEGORY switch to the GENERATOR CLOCK category.
6.
Set the GENERATOR CLOCK to INTRNL position.
7.
Using the SETUP SELECT switch and the appropriate softkey, set the INTERNAL FREQ to 1.2 k.
8.
Set the SETUP CATEGORY switch to the PATTERN category.
9.
Using the MORE key and the appropriate softkey, select the FOX data pattern.
10.
If hard copy test results are desired, set the PRINTER switch to print on a time interval (15 MIN or 1 HR) or on
the occurrence of any error condition (ERROR).

Both error and time print events can be customized using the AUX PRINT EVENT auxiliary function.
See Section 3 of the FIREBERD 4000 Reference Manual for detailed instructions.
11.
Press the RTS and DTR switches (located to the right of the VOLUME control) to set both signaling leads HIGH.
Both switches will illuminated.
12.
Using the appropriate cables, connect the FIREBERD 4000 to the equipment under test.
13.
If performing a looopback test, establish a loop by performing the procedures which are appropriate for you DCE.
14.
Check that the PATTERN SYNC and CLOCK PRES LEDs located at the upper right-hand corner of the
FIREBERD 4000 are illuminated.
RESULT:
The FIREBERD 4000 has achieved pattern synchronization, and is gathering test results.
