TELESCOPE OPERATIONS

Receiver and other important configuration (config) files are located in the directory: /home/gbt/etc/config/

These files have names like: RcvrPF_1.conf, Rcvr4_6.conf, etc.

They are all text type files that can be read with the commands "cat" or "more", and can be modified with any Unix text editor provided you have the proper permissions.

An example of the first few lines of the RcvrPF_1.conf file follows:

prospero::/home/gbt/etc/config : more RcvrPF_1.conf # Prime Focus Receiver

# 0 = OFF, 1 = ON, 2 == STANDBY managerStateDefault := 0

# 2 = parameterEnums::refrigCool  ( 0 = refrigOff, 1 = refrigHeat, 3 = refrigPump ) cryoStateDefault := 2

In the example above, the lines that start with # are comments. You can see that the manager defaults to OFF, and the refrigerator control defaults to COOL. The defaults are used whenever the single-board (in this case gbtaio1) is rebooted. To change, for example, the PF1 manager default state to STANDBY, the parameter will be changed to 2, by editing the third line like:

managerStateDefault := 2
