Linksys SRW224G4P

Linksys SRW224G4P , 24-Port Managed Gigabit Switch with WebView and PoE .

24-Port Managed Gigabit Switch with WebView and PoE ,(24) 10/100 ports + (2) shared Gigabit combo ports + (2) Gigabit uplink ports

The Linksys WebView Managed switch allows you to expand your network securely. Configuration of the switch is secured using SSL for Web access. User control is secured using 802.1x security using a RADIUS authentication mechanism and can also be controlled using MAC filtering. Extensive QoS features makes the solution ideal for real-time applications like Voice and Video. The 4 priority queues together with the Weighted Round Robin and Strict Priority scheduling techniques facilitate efficient co-existence of real-time traffic with data traffic allowing them each to meet their QoS needs. Individual users or applications can be prioritized above others using various Class of Service options - by port, layer 2 priority (802.1p), and Layer 3 priority (TOS or DSCP). Intelligent Broadcast, and Multicast storm control minimizes and contain the effect of these types of traffic on regular traffic. IGMP Snooping limits bandwidth-intensive video traffic to only the requestors without flooding to all users. Incoming traffic can be policed and outgoing traffic can be shaped allowing you to control network access and traffic flow.

There are features that allow you to expand and grow your network of switches. Link aggregation allow multiple high-bandwidth trunks between switches to be setup. This also provides a level of reliability in that the system continues to operate if one of the links break. Spanning Tree (STP), Fast Spanning Tree, and Rapid Spanning Tree (RSTP) allow you to build a mesh of switches increasing the availability of the system.

The rich management functionality of the WebView switches includes SNMP, RMON, Telnet, and HTTP Management options, allowing you to flexibly integrate and manage these devices in your network.

Automatic Load Sensing - Power control circuitry automatically detects Power over Ethernet on access point before providing power. Power feeding of Ethernet limited for fixed 10/100 Base-T/TX ports. The solution can provide maximum output power per PoE port up to 15.4W on 24 ports simultaneously. Independent overload and short-circuit protection for each port.

SRF485 Ultrasonic range finder

The SRF485 is a single transducer ultrasonic ranger, based on our original SRF02 design. The SRF485 uses the RS485 standard for communications, for up to 127 modules on each RS485 bus. The SRF485 features an on-board 5v power regulator which can be supplied from 8vdc to 14vdc. Both power and RS485 signals are supplied to the module via a 10pin IDC connector, making cabling a large number of modules very easy. The Range of the SRF485 is 30cm to 5meters.

Specification

• Voltage - 12vdc (8vdc - 14vdc)
• Current - 10mA
• Range - 30cm - 5meters
• Temperature Compensation - -30 to +50 centigrade

• Mounting - 30.5mm x 30.5mm (1.2" x 1.2")
• Transducer - 16mm dia. centrally mounted.

SSC-32 servo controller

The SSC-32 (serial servo controller) is a small preassembled servo controller with some big features. It has high resolution (1uS) for accurate positioning, and extremely smooth moves. The range is 0.50mS to 2.50mS for a range of about 180°. The motion control can be immediate response, speed controlled, timed motion, or a combination. A unique "Group Move" allows any combination of servos to begin and end motion at the same time, even if the servos have to move different distances. This is a very powerful feature for creating complex walking gaits for multi servo walking robots. The servo's position or movement can be Queried to provide feedback to the host computer. There is even a 12 servo Hexapod sequencer built in. This allows complete control of all aspects of the alternating tripod gait simply by transferring a few values from the host controller. Any output can be used as a TTL level output. There are 4 digital inputs that are static or latched, so you don't have to worry about missing a short event. They can also be used as analog inputs. There are three terminal blocks for powering options. The DB9 input has true RS-232 levels for use with a PC.
