Table 5.1. 1053 Device Address settings (shaded area
factory
setting)
5.3.1. Setting the address switches
The listen and talk addresses (Device Address) over which the 1053 can be contacted via
its IEEE interface are selected by the Address Switches on the rear panel. For each
switch, the upper position will give a logic 1 and the lower position will give a logic 0.
The most significant bit (MSB) of the address is given by AS (switch 4), while the least
significant bit (LSB) is given by A 1 (switch 8). Note that address 31 (Address Switch
setting 11111) should never be used as this corresponds to untalk/unlisten.
