3.4 MAG IDENTIFICATION SYSTEM

3.4.1 Mag ID

Each DX magazine bears its own identification (ID) determined by

the combination of magnets in receivers located above the drive

wheel on the throat of the mag. This identification is used by the

camera to recall the remaining footage of a mag removed from the

body unfinished. The XTRprod can differentiate seven magazines (A

through G) via electronic sensors located within the LCD control

panel and recall the memorized footage for each. By comparison, the

less sophisticated display of the XTRplus can identify only three ma-

gazines (A, B, C).

The chart to the right represents the seven IDs which can be read by

the XTRplus and XTRprod cameras, with the corresponding ma-

gnet in receiver combination for each.

3.4.2 Changing the ID of a Magazine

The Mag ID of a particular magazine can be easily changed by the

user. Determine the magnetic receiver(s) that need to be changed ac-

cording to the chart above. Locate the small silver spanner tool loca-

ted on the coaxial roller in the feed side of the mag. Using this tool,

loosen and remove these receiver(s). A spare receiver is located at the

base of the coaxial roller. Install the appropriate receivers as necessa-

ry. Remember to change the letter decal on the outside of the feed

side door to match the new ID. For spare decals, contact your Aaton

representative.

ID of Mags on XTRplus 

vs XTRprod

As mentioned, the XTRprod

can distinguish seven maga-

zines because its sensors can

read all three receivers.  The

XTRplus, however, can only

distinguish three magazines, as

its sensors will only detect the

two upper receivers.  Be aware

of this fact when renting addi-

tional magazines.  For

example, a mag which is read

as a G on an XTRprod will be

read as a C on an XTRplus

camera; as the lower receiver

will not be detected.
