The NIRC/LWS Test Station

How to configure itThe test station in the Kohala Lab in Waimea is used to test software and electronics for both NIRC and LWS (and to some extent NIRSPEC). In order to use the test station it must first be configured for the appropriate instrument. In general there is a workstation that represents the instrument computer, a "crate" or other computer which represents the low-level control computer, and the electronics which are located in a rack in the Lab.NIRC
Make sure that the LWS 10BaseT line is disconnected from the bottom of the "SPARC CPU-5CE/16" board in the orange electronics rack (lower left). Plug the kaimu "100Base-FX" transceiver into the 26-pin connector on the "SPARC SBUS" card in the rack. Currently the TIP serial line only reaches to kaimu. Eventually a longer line leading to kolekole will be installed into an A/B switch, that will let you select NIRC or LWS. For now, check to make sure that the 26-pin micro-D serial cable is connected to "Serial A" on the "SPARC CPU-5CE/16" board in the rack. On kaimu, look in the file "/etc/ethers" for an entry "0:80:42:b:ea". For NIRC it should have "taz" after it. ("0:80:42:b:ea bugs" indicates it is set up for LWS.) If you need to change the file, type cd /usr/yp
Type "~#" in the tip window to get an "ok" prompt. (You may need to try this several times before you can get the computer’s attention.) Type "devalias". If there is no "hme" in the left hand column, follow this link to fix it. Once you see a line starting "hme" type "boot hme" at an "ok" prompt.
Currently we do not have enough 16-bit coadder boards. For many purposes you do not need to change these boards. It is necessary to change a keyword however. What is this keyword? You do not need to change the widget board. LWS
Make sure that the Ethernet is connected to kolekole (the LWS instrument computer). On kolekole the fiber connector plugs into the CPU board. If desired, switch the serial line for the tip connection. (Alternatively you can simply remote logon to the other computer and bring up the tip window that way.) Reboot kolekole. Change router information. Need more details here! Normally you do not need to change the coadder boards, as the LWS 12-bit boards will be installed. You do not need to change the widget board. |
