Backplane Bus Communication Velocity & Expansion Drivers
The IC697BEM713J module interfaces directly with the Series 90-70 high-speed backplane bus, extending local CPU rack signals to multi-rack expansion architectures. Backplane bus communication velocity and bus driver latency are optimized via high-bandwidth parallel buffer logic, maintaining deterministic scan synchronization across remote expansion chassis. Firmware flash compatibility and revision matching ensure signal integrity across multi-rack topologies up to maximum physical cable limits without introducing excessive backplane bus contention.
Frequently Asked Questions
Q: Can the IC697BEM713J bus transmitter module be removed or inserted into the backplane while the system is powered on?
A: No. The Series 90-70 backplane does not support hot-swapping for bus transmitter modules. The chassis must be powered down prior to physical installation or removal to prevent electrical damage to the CPU backplane drivers and interface buffers.
Q: What is the maximum physical cable distance allowed between the IC697BEM713J transmitter and its corresponding receiver module?
A: The maximum total cable length supported by the IC697 parallel expansion bus architecture is 15 meters (50 feet). Exceeding this physical limit induces signal attenuation and backplane timing violations.
Field Installation Guidelines
Ensure the rack main power supply is completely isolated before inserting the IC697BEM713J into the designated CPU or expansion slot. Secure the module in place using the top and bottom rack retaining screws to establish solid chassis ground continuity through the mounting frame. Interconnecting expansion cables must be routed in dedicated, grounded metallic conduits away from high-voltage AC lines to prevent capacitive coupling and EMI interference on high-speed data traces. Both ends of the expansion bus cable shield must be grounded in accordance with standard industrial grounding practices.
