6.2 Addressing of Plugins

6.2.1 Plugin in Subrack

The Monitor terminal connects through the ACU to a serial bus on the subrack backplane which is

accessible by all plugins.

At any time, only one of the plugins in the subrack can be logically connected to the Monitor inter-

face. The appropriate plugin interface is addressed (i.e. selected) according to its physical position

in the subrack, starting with the leftmost slot number 01 and ascending rightwards to number 12. To

select a plugin in slot number nn just type %nn in the terminal, e.g. to select the plugin in slot 7

type %07.

Figure 6-1: Plugin Addressing Scheme

To see which units in a rack are available, you can use the ECHO command. Each unit will respond

with its associated slot number (%SN).

The response could be: %01 %03 %08 %10 %11

Notes:

! The ECHO command is not echoed on the terminal

! The selection command (%nn) is not echoed on the terminal

! Each command must be terminated by a carriage return.

rectly.
