(12-slot and 16-slot Universal Backplanes Only) Figure 2: LRE001 Whenever an application requires more modules than the selected Universal Backplane can accommodate, or whenever some modules must be installed in another location, an RX3i Serial Bus Transmitter Module, IC695LRE001 (Figure 2), must be installed in the last slot of the Universal Backplane. Note that only 12-slot and 16-slot Universal Backplanes accommodate the LRE001. The Bus Transmitter module (LRE001) is connected to the first Expansion or Remote backplane via a cable. Subsequent racks are daisy-chained together using cables (see Figure 5 through Figure 7). The D-connector (right side, Figure 3) is used to connect the Rx3i Serial Expansion backplane to the LRE001. Remote Backplanes may also be connected to the RX3i system in this manner. Figure 3: 5-Slot RX3i Serial Expansion Backplane IC694CHS398 Use of Expansion and Remote Backplanes is summarized on the following pages. For more information about the Serial Bus Transmitter module and cables, refer to Section 5:.

Refer to Chapter 4 for descriptions and specifications of the RX3i Power Supplies. For information about Series 90-30 Power Supplies the GEK-0898, Series 90-30 I/O Module Specifications Manual. n If the system includes only Expansion Backplanes, the total distance from the CPU to the last backplane cannot be more than 15 meters (50 feet) n If the system includes any Remote Backplanes, the total distance from the CPU to the last backplane cannot be more than 213 meters (700 feet). Remote Backplanes provide the same functionality as Expansion Backplanes over a much greater distance. Remote Backplanes have extra isolation circuitry that lessens the effect of unbalanced ground conditions that can occur when backplanes are located long distances from each other and do not share the same ground system. Communications between the CPU and a Remote Backplane may take slightly longer than communications between the CPU and an Expansion Backplane. This delay is usually small compared to the total CPU scan time. PACSystems* RX3i System Manual Section 2 GFK-2314T Sept. 2019 Introduction 17 1.5.1 Expansion System with One Expansion or Remote Backplane An Expansion system can consist of a Universal Backplane with just one Expansion or Remote Backplane. This example includes one Universal Backplane IC695CHS012 and one Expansion Backplane, IC694CHS392. Each Backplane in this example has a DC Power Supply. Together, they accommodate 19 discrete, analog, and specialfunction modules. These backplanes are located 15m (50 ft) apart. They are connected via an Expansion Cable IC693CBL302, which has a built-in terminating resistor. If it were necessary to locate the second backplane more than 15m (50 ft) from the Universal Backplane, a Series 90-30 Remote Backplane could be used with a custom-length cable and external terminating resistor.
