All ports are active at all times, however only one port may be used at a time.

  • Page 29: Fiber-Optic Serial Communication

    Model 100U1000 The RS-232 port is setup as a Data Circuit-terminating Equipment (DCE) port. When connecting to a Personal Computer (PC) a straight one-to-one cable should be used. A null modem is NOT needed. The settings and pinout diagram for this port can be found below. Table 2-1.

  • Page 30: Usb Communication

    This port can be used in conjunction with either an AR model IF7000 RS-232 to Fiber-Optic Interface (1200 to 9600 baud only) or an AR model IF7001 USB to Fiber-Optic Interface (19200 baud only). Note that these devices use SMA connectors so a fiber-optic cable is needed with ST connectors on one end and SMA connectors on the other.

  • Page 46: Troubleshooting

    Model 100U1000 TROUBLESHOOTING CAUTION: The transistors used in the Model 100U1000 amplifier are GaN HEMT transistor. These devices are very reliable when installed in a suitable circuit, but they can be easily damaged by improper troubleshooting or handling techniques. The gate junctions of the GaN HEMTs have a high input impedance and are susceptible to static damage or damage due to the use of an ungrounded soldering iron.

  • Page 47: General - Reading Faults

    Model 100U1000 4.3.1 General - Reading Faults The Model 100U1000 incorporates relatively simple fault detection circuitry, which makes use of the digital display panel to alert the user or technician which component(s) need service. Use of these indications can usually expedite troubleshooting of the amplifier. Most faults can be immediately determined down to the assembly level.
