Master port configurations support up to 100 user-defined commands per port with optimized polling logic for nodes experiencing communication delays. Optical isolation rated at 500 V is implemented between the serial application ports and the backplane to eliminate ground loops in heavy industrial environments. Full hardware handshaking control on PRT1 and PRT2 allows direct integration with radio telemetry, modems, and multi-drop RS-485\/RS-422 topologies.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x MVI56-MCMR Communication Module\u003c\/li\u003e\n\u003cli\u003e2 x RJ45 to DB-9M serial adapter cables\u003c\/li\u003e\n\u003cli\u003e1 x 6-foot RS-232 configuration cable\u003c\/li\u003e\n\u003cli\u003e1 x Product documentation and resource CD\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis Placement:\u003c\/strong\u003e Install the module into any available slot of the ControlLogix chassis.
