8. If the Geo MACRO Drive has been configured prior to this setup, then it may have been assigned a
station number and/or may have some enabled nodes. You would need to know what the station
number is in order to perform ASCII communication, or which nodes are enabled in order to issue
MS commands.
number is in order to perform ASCII communication, or which nodes are enabled in order to issue
MS commands.
The following commands can then be issued to reset the Geo MACRO Drive(s) back to its factory
default settings:
default settings:
MS$$$***15 will broadcast a global reset to stations associated with all enabled nodes
MSSAV15 will broadcast a Save to stations associated with all enabled nodes
MS$$$15 will broadcast a reset ($$$) to stations associated with all enabled nodes
9. Assuming that the Geo MACRO Drive(s) is or has been reset to factory default settings, we will now
try to establish MACRO ASCII communication by issuing:
MACSTA255
This command will establish MACRO ASCII (direct) communication with the first unassigned Geo
MACRO Drive (if more than one is in the ring) starting from the OUT/Transmit fiber or RJ45 out of
the Geo Brick Drive.
MACRO Drive (if more than one is in the ring) starting from the OUT/Transmit fiber or RJ45 out of
the Geo Brick Drive.
10. When in ASCII mode, download from the editor or issue the following commands in the terminal
window:
I995 = $4080
; MACRO IC ring configuration, typical slave setting
I996 = $0F4003 ; Node activation (servo nodes 0, 1) –User Input
11. Issue a Control^T in the terminal window to exit ASCII mode communication
Master Slave (MS) commands should now be available for nodes 0 and 1 (per this example).
12. Clock Settings
The phase frequency should be set the same as the master’s. Set the following:
MS0, I992 = Value of I7000 (or I6800)
MS0, I992 = Value of I7000 (or I6800)
; Max Phase Clock
MS0, I997 = Value of I7001 (or I6801)
; Phase Clock Divider
13. Ring Check Error
Enabling the ring check error function on the Geo MACRO drive requires computing and setting the
following parameters:
MS0,I8
following parameters:
MS0,I8
-> I80*(I6802+1)
MS0,I9
-> I81*(I6802+1)*(I8+1)
MS0,I10
-> I82*(I6802+1)*(I8+1)
Where I8, I80, I81, I82, and I6802 are masters’ parameters.
14. Station Number
The station number is used for ASCII communication.
MS0, I11 = 1
; Assign Station Number #1 –User Input
15. Issue MSSAV0 followed by MS$$$0 to maintain changes on the Geo MACRO Drive.
