Classification of LED Transmitter Device Important: The optical transmitter contains an LED system and is classified “CLASS 1 LED PRODUCT” per EN60825-1 (+A11), Safety of Laser Products. Contact NLynx Technologies for repair if your GEMINI EXPRESS MULTIPLEXER ever requires maintenance.
• • • • • • • • • Verify that the host work station controller’s (WSC) capacity has not been exceeded. Verify that the device is properly terminated. A peripheral is terminated when its twiaxial port has two 54.9 ohm resistors located between the “A” phase pin & earth ground and the “B” phase pin & earth ground. Termination is provided by a “Y” or “T” cable assembly or by a terminating balun (i.e. ASFT series). Verify that there are no polarity reversals in the cable.
UNPACKING PROBLEM SOLVING Remove the packing material and check for the items below: If problems are encountered with the GEMINI EXPRESS MULTIPLEXER, the following guideline is intended to provide a quick resolution. GEMINI EXPRESS MULTIPLEXER A (100-240 VAC) input external power supply is attached on the rear panel. USER'S MANUAL AC POWER CORD 1.) Collect all information relevant to this application. • GEMINI EXPRESS MULTIPLEXER serial numbers • Host type and operating system software level.
1. The external power supply is mounted on the rear panel of the GEMINI EXPRESS MULTIPLEXER. The AC power cord must be firmly inserted into the external power supply and strained relieved. 2. Insert the male end of the AC power cord into a properly wired receptacle. All data & mode LED’s on the GEMINI EXPRESS MULTIPLEXER will activate for two seconds and fade off.
DESCRIPTION The GEMINI EXPRESS MULTIPLEXER’s indicators and connections are described below. MULTIPLEXER will activate for two seconds and fade off. The amber power LED on the front panel, the green power led on the top of the external power supply, and the TX LED will activate and remain on. At this time the data activity LEDs will flash at the host’s polling rate. The RX LED will be off until the remote Multiplexer is installed. Device side Multiplexer installation.
INSTALLATION CONFIGURATION Host side Multiplexer installation. The configuration switch settings are shown below. 1. Set the configuration switches on the rear panel of the host side GEMINI EXPRESS MULTIPLEXER as follows: ON SWITCH 1 ON SWITCH 2 ON for a point to point application or SWITCH 1 ON SWITCH 2 OFF for a ring application. 2. The GEMINI EXPRESS MULTIPLEXER is designed for a 19” rack. The unit should be properly installed using all four mounting holes. Rack hardware is not provided.
MODE DESCRIPTION A “POINT TO POINT” link is comprised of two Multiplexer s connected by a single backbone. A diagram of a “POINT TO POINT” link is provided below. 62.5 micron multimode fiber SYSTEM 3X GXM8 GXM8 UTP cabling STAR PATCH PANEL Mul tiple Multiplexers which are connected in series with fiber optic transmit to fiber optic receive constitute a “RING” topology. A diagram of a “RING”application is provided below.
62.5 micron multimode fiber Remote Controller GXM8 GXM8 GXM8 UTP cabling COLLAPSED RINGS The Ring mode is seldom implemented as depicted in the previous section. Typically, fiber optic cables star out from a central location. Therefore, a ring is created by interconnecting the fiber optic star segments at the central location. This technique is known as a collapsed ring.
