Above antennas are having GAB Rabbit M&C Control cards (Released GAB system for individual antenna will be informed by Analog-backend group). 2. gabserver program always run as a deamon on elab@loconf pc, make sure that the program is running. If gabserver is not up, please start using the following commands. ssh -Y elab@loconf >cd /home/elab/gab/ >./gabserver 3. start the ONLINE client >gabcli 4.

IF command given to non-configured antennas, "Invalid Antenna" message will occurs. (2) GAB System Monitoring : To get this window type 'gabm' and 'sela ', where x is antenna selected for monitoring. This window will show real-time GAB system set-point configurred using either ONLINE or individual browser program of Rabbit card. Detector Power is in Voltage at present. GAB Configure window show GAB status rather than command issued from the ONLINE. i.e. This ONLINE window interprete the data received from GAB System rather than command issued from ONLINE. ###################################################################################### NOTE : (i) To set GAB sub-systems, any sub-set of antennas can be configured/selected through any user. (i) If GAB command issued other than non-configured antenna or antenn mask contain non configured antenna(s), ONLINE GAB commands will respond by "Command Successful, INVALID Antenna" message. i.e. command to antennas which are communicating will go successful but along with it will display non-communicating antennas. (iii) If GAB attenuations are set directly without setting the GAB (i.e. stgablo and stgabconf), ONLINE will give information "ANTENNA NOT SET". This is precautionary message that GAB sub-system is un-set and need to SET first before setting the attenuations directly. (iv) GAB LO below 600 MHz can not set through the ONLINE. ######################################################################################
