Initial Power On
And Checkout
3.1 Overview
The Ka-Band TWTA is normally operated in the REMOTE mode via the serial interface. The
remote control device can be an optional CPI Remote Control Unit (
01032300
), an IBM compatible
computer with an RS-232 or RS-422/485 serial port or an Ethernet connection. In the LOCAL
mode, three push button switches control the amplifier and its state is monitored by five LEDs.
Once the amplifier has been manually set for REMOTE operation, all of the amplifier monitor and
control functions can be used. This chapter describes:
•
LOCAL controls and indicators
(Section 3.2)
•
The optional Remote Control Unit controls and indicators
(Section 3.3)
•
Operation with P.C. computer and remote control software
(Section 3.4)
•

NOTE: Some of the LEDs on the front panel blink for one condition and
remain lit but do not blink for other conditions. In the text of this manual,
LEDs that blink for a particular operation are flagged (LED blinking) in the
text. If the LED is lighted and does not blink, the text indicates that the
LED is lit.
