(Analog):
(4)
RJ-45 Shielded version
Analog Pin 4,5 – Balanced, transformer coupled
Status Port RS-232:
RS-232 Pin 2=T, Pin 3=R, Pin 5=Gnd.
Ethernet port.
AC INPUT
:
AC mains voltage is applied through the IEC connector.
90– 265 VAC 47-470 Hz.
Power Supply:
The distribution amplifier uses a “Universal Input” switching power supply for cool and
reliable operation. The power supply accepts any common voltage between 90 and 265
VAC or 100 to 370 Volts DC without any adjustment. A separate line filter is built into
the DA-422-IRIG-2X4 for an additional measure of EMI suppression. The Power supply
used is UL listed and approved by several other agencies.
Remote Status:
Connecting a computer running a terminal program such as Hyperterminal set up as
9600-N-8-1 allows control and status information to be passed from or to the distribution
amplifier. Connections for RS-232 are described in the section above.
Hitting Enter (C/R) will cause the DA-422-IRIG-2X4 to respond with: DA-422-IRIG-
2X4 #XXXX> Where XXXX is the serial number of the unit.
KEYWORDS:
The following are keywords or words that are used by the DA-422-IRIG-2X4 to receive
status or issue commands to the unit. The keywords may be upper or lower case.
Incorrect typing or misunderstood words are returned as typed followed by a question
mark.
STATUS
(C/R) Returns the status of the distribution amplifier.
MASK
(C/R) Masks current alarms from being reported every 2 minutes
UNMASK
(C/R) Unmasks all alarms.
