4 Connecting the modules → Connecting the base
1. Obtain another feed point for the supply voltage.
2. Operate the modules with two interfaces in order to increase
the data
throughput.
The modules situated on the right of
the extension socket are
supplied by the extension socket and the modules located to the
left must be supplied via the socket on the far left.
Crossing the UART lines is only nece
ssary in the second case. The
factory setting of the DIP switches is the 1:1 connection (i.e. with
the interface lines directly connected), but check the setting of
the DIP switches just to be sure.
Using more than 16 modules
The power supply must be routed via the socket situated on the
far left as well as via the extension socket. The pin assignment is
identical to the pin assignment for the side connection (Fig. 4-6,
page 29). The DIP switches should be se
t to the crossover mode.
You have four possible ways of c
onnecting the interfaces.
1. You can use the connection on the socket on the far left.
In this way you can connect both inte
rfaces if you interchange
(cross) the UART lines via the DIP switches on the extension
socket. This variant is, for example, suitable for the connec-
tion of a Q.pac Test Controller.
2. You can use a Q.gate Test Controller.
Plug the Q.gate Test Controller into the socket on the far left
or far righ
t and cross the UART lines using the DIP switches
on the extension socket. The Test Controller then uses both
UARTs for communication with the modules.
3. You connect the interface of UART 1 via a cable on the left
socket
and the interface of UART 2 on the Q.bloxx Extension
Soc
ket QES.
Also in this case you must cross t
he UART lines via the DIP
switches on the extension socket, because the modules only
use the lines of UART 1.
4. You connect both interfaces via cable to the Q.bloxx Exten-
sion Socket QES.
In this way you can connect both inte
rfaces if you interchange
(cross) the UART lines via the DIP switches on the extension
socket. This variant is, for example, suitable for the connec-
tion of a Q.pac Test Controller.
DIP switch settings
The extension socket is operated in one of two modes depending
on the application:
