18. You should be able to see data flowing. And do an OPEN command, STA etc.
19. If everything is working, then you have two options for the following. You need to enable DHCP
addressing. You can log back in through your port 23 telnet session or use the monitor.exe program and
toggle it there.
20. At this point, you should be able to remove the cross over cable, plug in the Ethernet cable and then be
able to access the Aexeon device through either the port 23 telnet or port 4660 sessions from your laptop
over the network (after you switch back your laptop to DHCP enabled addressing)
21. You should be able to position the Aexeon and the 2 foot extension cord plug and the Ethernet all inside
the original CT-12K enclosure.
D. Connecting the CT-12K for on-site data storage
1. We wanted to be able to leave the CT-12K running and just be able to quickly stop data recording, get the
data, and continue.
2. 1 8”x8” electrical conduit box. ~$25 at hardware store. Drill out hole to fit 2 foot extension cord plug
through. Use Campbell Scientific type enclosure putty to make waterproof around cord.
3. $495. Acumen Instruments. DataBridge SDR2-CF starter kit.
https://www.acumeninstruments.com/store/Scripts/prodView.asp?idproduct=16. Includes reader and 4
GB storage card. Buy at least one more card (another ~$40 from them).
4. Length of 3-5 wire shielded cable to reach from ceilometer into conduit box with proper 9 pin serial
connectors on both ends (see instructions on soldering below)
5. Look over the Acumen doc from http://www.acumeninstruments.com/pdf/SDR2-CF_CG_10.pdf
6. Create a telnet session at 115k baud, 8N1 settings (typically the defaults).
7. Hit return a couple times to get the Acumen prompt. It should have a blue background like what shows up
in the Acument doc
8. Set data and time (option 1)
9. Configure the dataport (option 9)
a. B (2400)
b. D (701) 7 bit null
c. Handshaking off
10. File system functions (7)
a. Current file (like CEIL.dat)
b. Current directory (something like \DATA)
11. Recording parameters (6)
a. Overwrite on
b. Append on
c. Time stamping Y (this is important as the only way to have a time stamp is for it to be provided
by the Acumen device; there is no time stamp in the CT-12K data)
d. ASCII code 03 (this is at the end of the data stream)
e. Time stamp- use a complete one
12. Connect up the serial line from the ceilometer to the Acumen. Start recording
13. If your telnet session is still going and you’re connected to the acumen from your laptop, then you’ll see
the number of bits being recorded growing
14. Stop recording after a while, and pop out the flash drive, use the usb to flash drive device and check the
output files. You should see data followed by a time stamp.
