(C/R) Returns list of valid keywords.
Entering the keyword “Status” results in the DA-422-IRIG-2X4 displaying the current
status including output faults, and power supply voltages.
If a fault is detected, the DA-422-IRIG-2X4 will output a fault message identifying the
fault. Every two minutes, the message will be repeated unless the fault is cleared. When
the fault clears, the DA-422-IRIG-2X4 will output a message stating the fault has cleared.
If two minute fault reminders are not desired, typing the command MASK will cause the
DA-422-IRIG-2X4 to mask all current faults and stop reporting every two minutes. If a
fault that was masked is cleared, the fault clear message will be sent. If the fault re-
occurs, the masking for that port will not be set and the fault will be reported every 2
minutes.
Typing the command “Unmask” will remove all fault reporting masking.
Ethernet Port:
The Ethernet port may be used in exactly the same way as the RS-232 port by using a
Telnet program to connect to the IP address of the DA-422-IRIG-2X4. The IP address of
the port may be set to a fixed address or be dynamically set through DHCP. The factory
default is DHCP mode. The default telnet port is 10001. The default XPORT control port
is 9999.
The Ethernet port module is a Lantronix XPort module. It is recommended that the
Lantronix web site
WWW.lantronix.com
be consulted to understand how to use the
interface. A utility program from Lantronix called Device Installer (current version
4.1.0.9) should be downloaded and used to set up the IP address. This utility program
makes it easy to set up the parameters of the XPort device to customize it for the
particular network application.
Note that the XPort must be configured to provide a Modem Ctrl Out (DCD) signal on
configurable pin (CP) #1 (input, active low). This is necessary for the DA-422-IRIG-
2X4to switch control ports from the RS-232 to the Ethernet port when a telnet session is
established.
When the IP address is properly configured, a telnet session may be started to
communicate with the DA-422-IRIG-2X4. To do so on a typical windows based
computer, select “start”, “run” then enter “CMD”, and “OK”. A cmd.exe window will
open. In the window type “telnet 192.168.1.140 10001”. The actual IP address will of
course have to be used (instead of 192.168.1.140) The telnet program will notify you of a
successful connection. Pressing the “enter” key a few times should return the unit id from
the DA-422-IRIG-2X4.
