ETAS Installation and Configuration
2.2 Master/Slave Configuration
To extend the I/O capacity of the ES5340.2-M (master), a slave card (ES5340.1-
S) can be installed. This makes it possible to increase the number of analog and
digital outputs by six each.
For this purpose, you have to decide whether you are going to work with an
FPGA model or a model on the Real-Time PC.
Using an FPGA Model on the Master
By connecting the master and slave card of what is referred to as a Gigabit Link,
all the slave card outputs can be addressed by the FPGA model with the typically
low latencies (< 1 μs) (see "Connecting Master and Slave via Gigabit Link"
on page 25).
Using a Model on the Real-Time PC
In this case, the ES5340.1-S can simply be inserted into a PCI-Express slot – once
configured in LABCAR-RTC, the outputs of the ES5340.1-S can be addressed via
the LABCAR-OPERATOR Connection Manager.
2.2.1 Connecting Master and Slave via Gigabit Link
The following figure shows the connection of an ES5340.2-M with an ES5340.1-
S via Gigabit Link.
The bridge for the Gigabit Link is a small board with two connectors supplied
with an ES5340.1-S. The slave card has to be installed to the right of the master.
First connect master and slave with the bridge (see figure) and then insert them
into two neighboring PCI-Express slots.
