can no longer make any changes. Conﬁguration changes can be re-enabled at any time

by moving the switch back to the ʻEnabledʼ position.

If you want to keep a hard copy printout of the current conﬁguration of the Br-ANA,

you should use the <ESC>ape key to redraw the screen while ʻsaving to ﬁleʼ in the mo-

dem program running on your computer. This ﬁle can be printed out at any time, or

spliced into the documentation package for your project.

A) First Address:

The front panel switches are always used for the RS-422 Serial Port Ad-

dress. This toggle selects whether the outputsʼ address is set from:

1) Address stored in the AutoDownload ﬁle. This is the Default.

2) Address from the Serial Port Address switches on the front of

the Br-ANA. This is the default if no AutoDownload ﬁle is

loaded.

3) Addressed at a location you specify.

If twelve bit resolution has been selected, then any ʻillegalʼ

twelve bit ad-

dress will be skipped.

B) Twelve Bit Resolution:

If using a v1.1 AutoDownload ﬁle generated with Pc•MACs version

2.02.212.xxx or later, this will be set automatically for you from data in the

AutoDownload ﬁle.

When toggled ON, the output resolution will be twelve bits. This works out

to a resolution of one part in 4096. With a 0-10 volt output, each step will be

.00244 volts. If you are using 12 bit resolution analogs, you must carefully

account for the locations and number of output channels you are using.

Each 12 bit resolution input takes 1-1/2 eight bit channels. The Br-ANA wonʼt

let you set the ﬁrst address for a 12 bit analog channel to any address that

can be evenly divided by three (0, 3, 6, 9, etc.). This is because it uses these

bytes for storing the least signiﬁcant four bits of the next two 12 bit resolution

channels. Any 12 bit resolution channel that is addressed at an address that

can be divided evenly by three plus one (addresses 1, 4, 7, 10, etc.) will

need to have the previous address sent (or burnt into the Flash Memory) so

that its lowest four bit nibble isnʼt lobbed off. Any 12 bit resolution channel

that is addressed at an address that can be divided evenly by three plus two
