2. INSTALLATION
This Chapter explains the procedures for installing your Lx1553-5. There are five
steps to installation:
Step 1: Set the Hardware Configuration
Step 2: Insert the Card into the Computer
Step 3: Install the Driver Software
Step 4: Set the Card Number and Test the Installation
Step 5: Connect to the MIL-STD-1553 Databus(es)
After the installation steps are completed, the Lx1553-5 device is ready to
communicate on the MIL-STD-1553 databus(es).
2.1 Step 1: Set the Hardware Configuration
In an ESD safe environment, set the jumpers appropriately for your installation.
The Lx1553-5 contains on-board 75 ohm terminating resistors that may be used
with direct coupling. A second bus terminator must still be used at the other end
of the bus. By having the jumpers in place, the termination resistors are selected.
Figure 2.1 shows the terminating resistor jumpers. The on-board terminating
resistors should not be selected with transformer coupling. For more information,
refer to Appendix A: Coupling and Termination.

WARNING
Static Discharge
As with most electronic devices, static discharge may damage or degrade
components on a circuit card. When handling a circuit card, the user
should be grounded (e.g., through a wrist strap). Each circuit card is
shipped in an anti-static bag, and should be stored in a similar container
when not installed in the computer.
