Turbo PMAC On-line Command Specification 273

$$$

Function: Full card reset.

Scope: Global

Syntax: $$$

This command causes Turbo PMAC to do a full card reset. The effect of $$$ is equivalent to that of

cycling power on Turbo PMAC, or taking the INIT/ line low, then high.

With the re-initialization jumper (E51 on a Turbo PMAC, E3 on a Turbo PMAC2) OFF, this command

does a standard reset of the Turbo PMAC. Turbo PMAC copies the contents of the flash memory into

active main memory during a normal reset cycle, overwriting any current contents. This means that

anything changed in Turbo PMAC's active main memory that was not saved to flash memory will be lost.

Contents of the Option 16 supplemental battery-backed parameter memory are not changed by the $$$

command.

With the re-initialization jumper ON, this command does a reset and re-initialization of the Turbo PMAC.

Instead of copying the last saved I-variable values from flash memory into active memory, Turbo PMAC

copies the factory default I-variable values into active memory.

Note:

Because this command immediately causes Turbo PMAC to enter its power-up/rest

cycle, there is no acknowledging character (<ACK> or <LF>) returned to the host.

Example:

I130=60000 ; Change #1 proportional gain

SAVE ; Copy active memory to non-volatile flash memory

I130=80000 ; Change gain again

$$$ ; Reset card

I130 ; Request value of parameter

60000 ; Turbo PMAC reports current value, which is saved value (Put E51 {E3} on)

$$$ ; Reset card

I130 ; Request value of parameter

2000 ; Turbo PMAC reports current value, which is default
