Autoconfigure

A

command: no data required.

Setup

SE

command: The program prompts for a one-digit baud rate multiplier (1

and 2 are valid), then for a one-digit resistor value (1 to connect the line
termination resistor and 0 to disconnect). Just pressing the

Enter

key in

response to either of the first two prompts leaves the previous value
unchanged.

There is a third prompt, for debugging mode: a 1 disables the scanner’s
watchdog and any other value (including just the

Enter

key) re-enables it.

Scan list

SC

command: The program prompts for the length of the scan list and then

the scan list itself. You enter each adapter in the scan list as a one-digit
rack number (0–7) followed immediately by a one-digit starting group
number (0, 2, 4, or 6).

You may need to make several identical responses in a row. You can
compress this repetitive input by using a repeat count with an asterisk. For
instance,

3*14

would enter the adapter at rack 1, group 4, in the next 3

positions in the scan list.

link statulFault dependent group

F

command: The program asks you for the rack and starting group number

of each adapter in the current scan list. You reply with the fault dependent
group number (0 to 7, or N for no group).

As with the scan list command, you may need to make repetitive
responses. Again, use a repeat count with an asterisk. For instance,

6*N

is

equivalent to making the

N

response 6 times, leaving the next 6 adapters

out of any fault group.
