Async Rs232 To Rs422/485 Interface Converter - Db9 To Terminal Block, Gsa, Taa IC821A
ASYNC RS232 TO RS422/485 INTERFACE CONVERTER - DB9 TO TERMINAL BLOCK, GSA, TAA
Manufacturer Part Number: IC821A
Convert async RS232 to RS422/485 at speeds up to 115.2 kbps with distances up to 4000 ft. over CATx cables. The BLACK BOX(r) Universal RS-232 to RS-422/485 Converter with Opto-Isolation isolates and converts RS-232 signals into RS-422/RS-485 signals and vice versa. Unlike other converters external software is not required to control data flow. The RS-232 input is wired for DCE through a DB9 female connector and RS-422/RS-485 signals are interfaced through a removable terminal block. To supply external power to the terminal block you need our 120-VAC/12-VDC Wallmount Power Supply (PS1003). For RS-232 the connection requires RD TD and Signal Ground. In RS-422 mode the driver is always enabled for full-duplex communications. A twisted pair is required for transmit and a twisted pair is also required to receive. A ground reference wire is also needed. Switch settings are Switch 1 RS-422 Switch 2 Echo On Switches 3 and 4 4 Wire. In both RS-485 modes the RS-485 driver is automatically enabled during each space state by the presence of an RS-232 signal. When the RS-232 data is in a mark or idle state the RS-485 driver is disabled and the RS-485 data lines are held in a mark state by the bias provided by a 4.7-ohm resistor the value of this resistor may need to be changed depending on the termination you use. To connect to several RS-485 devices with minimal wire select the unit's 2-wire half-duplex RS-485 mode. When data is requested the addressed device transmits and then reverts back to receive status. Switch settings for this mode are Switch 1 RS-485 Switch 2 Echo Off Switches 3 and 4 2 Wire. For 4-wire master/slave circuits select the unit's 4-wire full-duplex RS-485 mode. In this mode addressed devices can receive data while transmitting data from a previous request. When used as a master in a single-master system Switch 1 may be selected because the unit is the only transmitter in the system. When used as an RS-485 slave the RS-232 device must provide addressability. Biasing in a master/slave system is provided by the end-of-line slave. Switch settings for this mode are Switch 1 RS-485 Switch 2 Echo On Switches 3 and 4 4 Wire.

Switches, routers, and wireless access points
Switches, routers, and wireless access points perform very different functions in a network.
A computer network, or data network, is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections (data links) between nodes These data links are established over cable media such as wires or optic cables, or wireless media such as WiFi.Switches
Switches are the foundation of most business networks. A switch acts as a controller, connecting computers, printers, and servers to a network in a building or a campus.
Switches allow devices on your network to communicate with each other, as well as with other networks, creating a network of shared resources. Through information sharing and resource allocation, switches save money and increase productivity.
There are two basic types of switches to choose from as part of your networking basics: managed and unmanaged.
- An unmanaged switch works out of the box but can't be configured. Home-networking equipment typically offers unmanaged switches.
- A managed switch can be configured. You can monitor and adjust a managed switch locally or remotely, giving you greater control over network traffic and access.
Routers
Routers connect multiple networks together. They also connect computers on those networks to the Internet. Routers enable all networked computers to share a single Internet connection, which saves money.
A router acts a dispatcher. It analyzes data being sent across a network, chooses the best route for data to travel, and sends it on its way.
Routers connect your business to the world, protect information from security threats, and can even decide which computers receive priority over others.
Beyond those basic networking functions, routers come with additional features to make networking easier or more secure. Depending on your needs, for example, you can choose a router with a firewall, a virtual private network (VPN), or an Internet Protocol (IP) communications system.
Access points
An access point* allows devices to connect to the wireless network without cables. A wireless network makes it easy to bring new devices online and provides flexible support to mobile workers.
An access point acts like an amplifier for your network. While a router provides the bandwidth, an access point extends that bandwidth so that the network can support many devices, and those devices can access the network from farther away.
But an access point does more than simply extend Wi-Fi. It can also give useful data about the devices on the network, provide proactive security, and serve many other practical purposes.
*Access points support different IEEE standards. Each standard is an amendment that was ratified over time. The standards operate on varying frequencies, deliver different bandwidth, and support different numbers of channels.
Wireless networking
Wireless networking is a method by which homes, telecommunications networks and business installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.CompSource will educate and help make this process enjoyable and easy.
Whether you're planning on using your network for basic home tasks or enterprise level security. You can tell our trained sales professionals your needs, and we’ll make custom recommendations to suit your specifications and budget. Our reps have extensive knowledge and love to share. We educate, not sell, CompSource makes sure you buy what you need and not waste money on what you don't. As with every decision we never push, it's up to you when, and if you make a purchase.
