The transient recorders in one rack share a parallel bus and are identified by their address. For a proper functioning rack all addresses should be unique.

The addresses range from 0 to 15. In order to change the transient recorder address you need to unmount the transient recorder first (see the for mounting instructions).

Then open the side panel.

for new TR 40-16bit-3U-opt the address switch is in the lower middle of the board. address swithc location

For older boards on the right side of the board a black (red before Oct. 2009) switch should be visible. The switch position 1 to 4 encode binary the address. The switch positions 6 to 8 define on the black switch the memory length (see there)

The ON position corresponds to a binary 1.

before Oct. 2009since Oct. 2009 
Address 0 Address 0 All switches are off, the resulting address is 0. This is the factory default for the left most transient recorder in a Rack-8 or the topmost in a Rack-2.
Address 1 Address 1 The lowest switch is on (20), the resulting address is 1
Address 5 Address 5 The lowest switch is on (20), the switch corresponding to four is also on (22), the resulting address is 5
