10 EX7000-OEM Introduction
INTERACTIVE CONTROL
As an LXI-compliant device, the EX7000-OEM has an embedded web server running which
provides a JAVA applet for interactively configuring the box for its specific configuration as well
as allowing for the direct control of components. Configurations are stored on the EX7000-OEM’s
non-volatile memory to simplify the software development cycle.

RELAY DRIVE CONTROL
The EX7000-OEM has been designed to provide maximum flexibility for controlling virtually any
type of RF/microwave relay or component. The 72 high-current drivers are divided into twelve
sections of six lines. Each section consists of:
• six high-current drive lines
• six indicator/status bits
• one reset line
• four relay ID bits
• one relay power input
• one 5 V input
• one ground
Each driver board is capable of recognizing and controlling either latching or non-latching relays.
A programmable delay (per driver board) dictates the amount of time allocated to relay settling
times and current cutoffs (for latching relays).
