Acc-24E2 Clock Settings
The Phase Clock and Servo Clock must be configured on each Acc-24E2S. Each system can have only
one source for the servo and phase clocks and jumpers must be set appropriately to avoid a timing conflict
or a watchdog condition.
Starting in UMAC-Turbo firmware version 1.937, the firmware will set the clock settings automatically
for the Acc-24E2 cards in the UBUS. To enable this feature, set jumper E16 from 2 to 3 for all of the
Acc-24E2Ss plugged into the UMAC. At re-initialization (either
$$$***
command or power up with E3
jumpered on UMAC), the firmware will know that all of the cards are in the auto configuration setup and
will assign the card with the lowest base address setting (usually $78200) the task of sourcing the clocks
by setting variable I19 to the appropriate register. The clocks will be set initially to the factory default
servo update cycle and phase clock cycle. For a better understanding of this feature, refer to the
description of I19 in the Turbo Software Reference Manual.
For UMAC Turbo systems with firmware older than version 1.937, set one of the Acc-24E2s to transmit
(E16 set 2-3) the phase and servo clock (usually the card at the lowest base address setting) and set the
rest of the Acc-24E2s to receive (E16 set 1-2) the phase and servo clocks.
For MACRO systems, the clock select jumper should be set to receive servo and phase clocks. For the
Acc-24E2S, E16 should be set 1-2.
