Abstract: An infrared LED of an IrDA transceiver module is usable to transmit IrDA signals as well as RC control signals. When making an IrDA transmission, the IrDA LED is driven with a lower amount of current. When making an RC transmission, the IrDA LED is driven with an increased amount of current such that infrared emissions received by an RC receiver are of adequate power to be received as RC control signals. A current-limiting circuit allows more LED current to flow the longer current is allowed to flow through the IrDA LED. By controlling the durations of infrared bursts in the RC transmission, the average LED current during infrared bursts of RC transmissions is controlled. Using this technique allows the IrDA module to be used to transmit RC signals at different transmission power settings. To reduce power consumption, the minimum transmission power necessary to engage in RC communications is used.

Abstract: The synchronization of trunk failover between two FC-AL switches when a primary trunk failure occurs is disclosed. If primary trunk T1 should fail, S1 bypasses the cascade port and sends a MaRK (MRK) ordered set out over duplicate trunk T2 to switch S2. In response, S2 sends an acknowledgement MRK ordered set over T2 back to S1. S1 then reconfigures the switch to establish T2 as the primary trunk, and acts as a masters in the failover process and initiates LIP ordered sets which are communicated to all devices in the system to initialize them. Note that when S2 receives the MRK ordered set and acknowledges it by sending an acknowledgement MRK back to S1, it acts as a slave in the failover process and does not attempt to initiate LIPs, thereby eliminating the possibility of multiple Loop Initialization cycles and reducing the time in which data cannot be transmitted.

The transmitter sets the remote controller in the first mode if a protrusion of the rotatable lever does not make contact with a mode selecting switch, and sets the remote controller in the second mode if the protrusion of the rotatable lever makes contact with the mode selecting switch due to the rotation of the rotatable lever, thereby simplifying components to set each mode using one hand or two hands.

Abstract: Light emitting diodes are placed side by side at a front end of the remote control transmitter in a manner that their maximum radiation directions, i.e. radiation directions each giving a maximum radiation intensity, are each inclined at an angle within a range no larger than 5 degrees outwardly of the remote control transmitter 1 and symmetrically with respect to a bisector of a line segment which connects center points of the light emitting diodes. The inclination, within a range no larger than 5 degrees, of each of the light emitting diodes used as light sources for remote control does not cause significant reduction in the radiation intensity. Accordingly, it is possible to widen the transmittable angle within a range no larger than 10 degrees without significantly reducing the radiation intensity at a central portion of the radiation range.

Abstract: A digital control circuit enables/disables the feedback of serial transmissions of an UART receive signal when the G-LINK output port is short circuited in a particular operational mode. In a conventional operational mode, the digital control circuit monitors the state of the UART's Tx output and during an UART transmission, the Rx line normally is used for statistics feedback to set to a high state and eliminate unnecessary or unwarranted UART interrupts generated by the G-LINK circuit. The digital control circuit thus enables the G-LINK signal feedback to the UART when required, thereby maintaining a functionality to identify the unit's operational mode and allows the serial ports of the G-LINK to be configured and utilized during conventional operational modes.
