Setup TSI-440 Frequently Asked Questions
Power requirements are approximately 6A @ 120 VAC 50/60Hz.
For communications, a TCP/IP connection via Ethernet is required - 10BaseT on the TSI-440 and 10/100BaseT on the TSI-880. On the TSI-880 a telephone line can also be wired to the integral modem to support direct PPP dial-in. If both Ethernet and telephone connections are impractical at the site an optional 420Mbyte Data Storage Module (DSM) supports off-grid operation via hot-swappable data collection from a remote TSI-880 system.
We highly recommend the use of a telephone line lightening protector, and some form of protection for the Ethernet lines, as an electrical storm can cause expensive damage to the instruments. YES sells a fiber-optic to Ethernet conversion kit that will isolate electrical surges.
Please see the TSI product data sheets for more information.
Both the TSI-440 and TSI-880 are supplied with a 10' AC power cord, and a 50 ft Ethernet connection 10Base-T RJ-45 cable for direct connection to your network hub. An internal surge protector helps to protect your hub However, many customers prefer to use fiber optic Ethernet isolators to help reduce the chance of lightning damaging their hub (we supply this as an optional kit or you can buy it locally).
Each TSI-880 system contains its own image processing system and can provide data in real time to any user with a web browser (that is, there is no client software like that used on the TSI-440 system). In addition, the TSI-880 integrates with the optional YESDAQ Data Visualization Engine software for collecting data from one or more TSI-880s into a database, or even by transferring up to 420 MB via a data storage module from a remote non-connected TSI-880 system. YESDAQ data can then be viewed with a simple web browser by any user on the Internet. TSI-440 data is viewable locally on the PC via the TSI Manager application that is provided with each TSI-440 system. It is the customer's responsibility to provide a network connection between a TSI-440 and the Windows NT PC that processes the data.
All TSI systems are pre-configured for AC line voltage prior to shipment based on the Purchase Order for 110/220, 50/60Hz
For mirror removal instructions, go to:
This is a MPEG video/audio 1 minute clip that explains how to replace the mirror. Your browser or media player should load this automatically and play it, and you need speakers and an audio card to hear the audio.
Additionally, you can download a MS-Word document of instructions here: http://www.yesinc.com/download/support/TSI/. Download the TSI_Mirror_Removal_and_Installation.doc file.
4. Does the TSI-440 and TSI-880 require a static IP address on the Ethernet LAN segment or can we use DHCP?
Yes, a static TCP/IP address is required, and your LAN administrator needs to assign this adddress prior to installation. During system setup you assign this static (i.e. non-DHCP) TCP/IP address, a "network mask" and also a "gateway address" if you plan to view data from outside your LAN. You also need to know your "DNS server" address. Your local system or network administrator can provide you with this information, which will be specific to your LAN.
This is governed by the rules of Ethernet: 100 meters with 10BaseT, but many hundreds of meters with fiber optics. See your local system administrator or refer to one of the many excellent references on Ethernet cabling located on the Internet.
YES. The mirror is heated; in extreme cases where winds can exceed 75 MPH you might want to add additional external IR radiant heating elements for wintertime mountain operation. Please contact YES technical support for help in planning your installation.
There are four 1/4-20 bolt holes in the electronics enclosure that are intended to mate to a flat, level surface. A strong table or frame can be built from "Unistrut" to hold the unit elevated, or it can be set directly on a flat roof.
Because you will need to periodically clean the mirror, access is important. If you mount it so the mirror is about 1.5m off the ground this will help to minimize image blocking when personnel are standing near the unit cleaning the mirror.
8. Does the TSI have to be mounted in a particular position? Can you rotate the mirror or configure the software to have it "point north"?
A TSI either has to point geographically north or south. The image processing and mirror rotation algorithms rely on this. The aiming precision required is about 1-2 degrees..
The TSI-440 and TSI-880 are packaged in metal NEMA enclosures with a heavy ground wire for customer attachment to a local ground rod or existing roof lightning rod system. We recommend that you do not connect this ground to the to AC power ground.
Simply aim the system either geographically north or south. Both theTSI-440 andTSI-880 have integral ephemeris-controlled mirror control servos with absolute encoders for continuous feedback. So you do not have to touch it once it is aligned north/south as it does this automatically
11. The TSI-440 won't report the time and azimuth after I plug in a "straight through" serial cable and verify all the comm settings are correct. Why?
Initiate a 'T' command on the comm software and set the LAT/LONG and TIME/DATE correctly. Additionally, verify that the PLATFORM HEADING value is set to ZERO.
Wind below 75 MPH should not affect the system. However, at sustained speeds in excess of 75 MPH (e.g. Antarctica), installing wind deflectors to dampen vibration modes. Be sure the system is well-grounded to eliminate static charge pickup that high winds create (e.g. hurricane strength in the 12 Beaufort range). The system needs to be properly anchored.
