1. 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. ONLINE Commands examples
>ante 8 20 12 8 15 3 23 29 27 // or ALLANT
cp 0;defs 0;subar 0 // OR ANY SUBARRAY
# init GAB System, settime : This command set-time for the Rabbit card and reset GAB settings.
>cp 9; initgab
# To SET GAB through runfile
$use cdset0 or cdset<X> x= user number to edit setupnew.txt for GAB settings at the end
> run set0gab // or set<X>gab X=1,2,3,4,5 user numbers
# to set LO
>stgablo('1400000','1400000') // LO values from 600000to 1500000 KHz
# to setgab attn
>stgabattn('10.0','10.0') // Attenuation values in the range of 0 to 31.5 insteps of 0.5
# to set custom 32 bit DIGITAL MASK -- For test purpose
>stgabconf('XXXXXXXX') D0 to D7 HEX word (total lenght 8)
# to equalize GAB antenna total power
>run gwblev

Two new window introduced in ondisplay.5
(1) GAB Configuration Status :
To get this window type 'gabs'
This window will show only the configured GAB antennas.
IF command given to non-configured antennas, "Invalid Antenna" message will occurs.
(2) GAB System Monitoring :
To get this window type 'gabm' and 'sela <x>', 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.
