USR 4204 Physical Features

USR4204 Physical Features

USR4204 Physical Features

1. Terminal Port – RS-232 port for connection to modem or computer serial port to configure and manage the USR4204 and connected devices. The terminal port supports an RS-232 asynchronous serial DTE connection via an RJ45 jack. See appendix A for pinout details. Terminal port activity can be monitored using the two adjacent LEDs. Both LEDs light when the terminal or modem connected to this port signals that it’s ready to receive or transmit data. For a terminal it is the DTR signal, for a modem it is the DCD signal. The left LED flickers when data is transmitted from the terminal port, the right LED flickers when data is received by the terminal port.
2. Serial Ports – Connect RS-232 network devices with RJ45 cables for device management.
The four serial ports are RS-232 asynchronous serial DCEs presented on RJ45 jacks. See appendix A for pinout details. Each serial port is represented by two adjacent LEDs, which light when the port is selected. The left LED flickers when data is transmitted from the serial port, the right LED flickers when data is received by the serial port.
3. Mains Input Port – Connect a C13 power cord from a nearby power outlet to the mains input port to provide power to additional network devices. The mains power input port is an IEC C14 fused inlet, rated for 8 amps maximum.
4. Power Output Ports – Connect power cords from up to two network devices (rated for a total of 8 amps combined) for individual power management. The power out ports are IEC C13 outlets, individually rated for 8 amps maximum.
5. External Power Supply Input – Connect the included Versa Power Kit to power the USR4204. The external power supply input delivers operating power to the USR4204 from the external low voltage power supply that is included with the product.
