2-4 Installing the Module
Multiple e-SAT/IN connections
In the multiple e-SAT/IN module system configuration, when several data
channels are needed, a network switch is required to multiplex the
communication between e-SAT/IN modules and the acquisition computer. The
Ethernet switch allows you to connect multiple e-SAT/IN modules to the
acquisition computer. The acquisition computer identifies each e-SAT/IN
module by its network address.
Connection hardware requires one standard 10 base-T Ethernet cable per
e-SAT/IN module, and a standard 10 base-T Ethernet cable to connect
between the network switch output port and the acquisition computer. Refer
to the figure “Multiple e-SAT/IN Ethernet connections” on page 2-5.
You must install the e-SAT/IN module software driver in the acquisition
computer before the computer will recognize the presence of the e-SAT/IN
module. Refer to the software installation instructions that accompanies the
Empower Software Instrument Driver Disk.
Network installation guidelines
Multiple e-SAT/IN module configurations use a local area network. This
dedicated LAN network requires a design based on the following guidelines:
• 10 base-T, 10 Mbps unshielded twisted-pair (UTP) cable
• A maximum distance of 100 meters (328 feet)
• An RJ45, eight-pin connector to terminate the 10 base-T twisted-pair
cable
• The use of a hub in this network configuration is not supported.
