Introduction: A Q.brixx system essentially consist of the same Q.bloxx modules packaged in a portable orientation. The individual modules, including the Q.gate are housed in an aluminum casing. When the individual modules are attached together, a complete Q.brixx system is created.
A maximum of 16 modules can be connected to a Q.brixx gate. The Q.brixx gate can be placed on the far left or far right, by default a Q.brixx system is shipped with the Q.brixx gate on the far left (when facing the modules). In the example below, the Q.brixx gate is on the far left attached to 8 modules.
Powering the system requires unregulated direct voltage of 10-30 VDC. Below are the connector types available on a Q.brixx gate:
1 x USB 2.0 port – Used to attach an external USB thumb drive. Data can be logged directly to this USB port.
1 x Ethernet port – The host interface to the PC. Communications via industry standard protocols (i.e. TCP/IP, ASCII, etc.).
1 x 3.5 mm port – This is the RS232 interface that can be used to configure the Q.gate’s IP address or attach an external GPS device.
1 x GND connector – Standard banana jack.
2 x Sync connectors – Used to synchronize multiple Q.brixx systems. LEMO plug (part # FGG.00.302.CLAD30Z).
1 x Power connector – Provides power to entire Q.brixx system. LEMO plug (part # FGJ.1B.302.CLLD62). The connector has 2 PINS, the upper pin is (+) and the lower pin is (-). Each Q.brixx system is shipped with 1 x AC power adaptor that has the LEMO plug integrated.
Just like all the other Gantner Instruments test controllers, the Q.brixx gate ships from the factory with a default IP address of 192.168.1.28.
Unlike the Q.bloxx modules, the Q.brixx modules are shipped from the factory with their node address already configured via the base. Similar to the Q.socket, the address is set using DIP switches 1-6 (binary form, 1st switch is LSB). The Q.brixx gate starts with address 0 and the module immediately to its right will have address 1.
Just like the Q.bloxx gate, the Q.brixx gate also has 2 x UARTS available. To use the maximum allowed 16 modules in a Q.brixx system, it is recommended to connect the first 8 modules to UART 1 and the second 8 modules to UART 2. Setting which UART the module is connected to is done via the base. On each base is a group of 4 DIP switches. When PINS 1 and 2 are up, the module is connected to the first UART. When PINS 3 and 4 are up, the module is connected to the second UART.
The heart of a Q.brixx system is the Q.brixx gate. Each Q.brixx gate is shipped with the 2 x handles (left and right side). As mentioned above, each module including the Q.brixx gate sits on a base. The first base secures to the left side handle first, all other bases are secured moving left to right using the 2 x screws integrated into each base. Tighten these screws using an Allen Wrench (Hex Key). After the final base is secured, attach the right side handle to the right side of the last base.
Notice that the left most base (designated for Q.brixx gate) is secured using the screws attached to the handle. All other bases are secured using their own integrated screws.
When all bases are secured inbetween the 2 handles, it is time to attach the Q.brixx gate and all other modules (A101, A104, A109, etc.) to the system. Start from the left most base and attach the Q.brixx gate. Moving left to right, attach the remaining modules to the bases. Tighten the 2 screws on the bottom of each base to secure the modules to the base (shown below).
Special Terminal Blocks: The Q.brixx modules use the exact same special terminal blocks that the Q.bloxx modules use. For more details, please see the section above under “Q.bloxx Modules“.
Special Q.brixx Connectors: There are a few modules in the Q.brixx line up that utilize special connectors. These special connectors must be specified at the time of order (not field-swappable).
The A104 module is considered a thermocouple input module because it can accept 8 x thermocouple sensors. The regular terminal blocks is still available but we provide a version with mini TC sockets. These sockets can be specified to accept a specific type of thermocouple (i.e. J, K, E, etc.) or a universal version (copper leads, shown to the right). This version does not require an external CJC terminal block (CJC is built-in).
The A107 module accepts 4 x electrically isolated analog inputs. We offer the sensor inputs as DB9 connectors as shown below. With this version, the module power supply (+V and 0V) is available on the socket, GND identifies the measurement ground. All 4 x inputs are still electrically isolated within the module.
It is also important to note the new sensor connections when using the DB9 connectors:
The A108 has 8 x electrically isolated analog inputs. The alternative version to the terminal blocks are BNC sockets. The measurement ground (-) and the module supply voltage are electrically isolated in the module. With the BNC version, the digital input and output channels are not available. For the BNC connector, the inner pin is (+) and the outer conductor is (-). When measuring current, you must use a proper external shunt resistance (measure the current by knowning the voltage drop and value of the shunt).
