FEATURES • Send async data across short- and medium-range distances. • Use existing in-house twisted-pair wiring to transmit data. • Choose from a variety of data rates as high as 115.2 kbps with the high- speed SHM-B. • Most offered as cards for rackmounting. • Models for multipoint applications available. • Microdriver 9 can be ordered with surge protection. • Choose nonpowered models for simple installation. OVERVIEW If you want to transmit data from your computing equipment further than the 50-foot (15.2-m) RS-232 limit but don’t need a modem (which can transmit data worldwide), then order a Microdriver 9, Short-Haul Modem-B, or RS-232/RS-485 Multipoint Line Driver. These compact, easy-to-install datacommunication devices can exchange data within a building or across town. Higher data rates yield shorter distances. For details and distance/speed specifications for specific models, see the following pages. What should you consider when choosing the model that’s right for your application? First, determine whether you need a nonpowered or powered device. The nonpowered models plug into the connector at the communications port of your DTE and derive their power from the port’s interface (RS-232/ITU V.24) via one or more of the connector’s pins. All Microdriver 9 models are powered this way. Before choosing a specific nonpowered device, you’ll need to confirm that your computing equipment has the pins needed to run the device. Then determine the gender of your computer’s comm port connector and select a model with the proper connector gender. Choose a powered device if your computer can’t support nonpowered units and/or you prefer to rackmount equipment. Our Short-Haul Modem-B, High-Speed Short-Haul Modem-B, and RS-232/RS-485 Multipoint Line Drivers are all powered, requiring standard AC current to operate. They’re available in standalone and rackmount card models. When choosing your model, consider your available installation space, the total units needed, and your existing equipment. Next, determine if your system or software support is sending data in a point-to-point or multipoint installation. Except for the RS-232/RS-485 Multipoint Line Driver, all models featured here are designed to work point-to-point. If you have a point-to-point network, you’ll need a device that matches the type of wiring in your installation, whether it’s in-house wiring for on-site applications or a 4-wire twisted- pair Local Area Data Circuit (LADC) leased from your phone company to send data off-site. In-house wiring will be either 2-or 4-wire twisted-pair cable that exists in your building or that you will install. Lastly, determine the speed you want your data to travel, reviewing your computer’s limitations to see if it supports high speeds, and the distance it must travel. You’ll also need to consider how much room for error you can tolerate in data exchanges, what wire gauge(s) will be used, and how many splices will exist in the wire. Microdriver 9 • Nonpowered, point-to-point, 4-wire or 5-screw terminal block. • Saves space—plugs into your PC’s DB9 serial port. • Sends data up to 17 miles (27.4 km) at 1200 bps using 24 AWG gauge wire. • Models are available with RJ-11, RJ-45, or 5-screw terminal block connectors. This compact short-range, asynchronous, point-to-point, full-duplex line driver plugs directly into your computer or terminal port, and all power is drawn from the RS-232 interface. It‘s perfect for installations where there‘s no room to spare. Surface-mount technology makes the Microdriver 9’s small size possible. Used in pairs, the Microdriver 9 enables two asynchronous RS-232 devices with DB9 connectors to communicate at distances up to 17 miles (27.4 km) at 1200 bps over 24 AWG wiring. Models available include: • The Microdriver 9 RJ-11 (ME790A-M, ME790A-F, ME792A-MSP, ME792A-FSP) has a female RJ-11 connector to connect to the twisted-pair lines and a male or female DB9 connector to connect to your computer port. Surge- protected (SP) versions feature 600-watt power dissipation at 1 ms and a response time of 1.0 picoseconds. • The Microdriver 9 RJ-45 (ME794A-M, ME1794A-F) has a female RJ-45 to connect to the twisted-pair lines and a male or female DB9 connector to connect to your computer port. • The Microdriver 9 5-Screw Terminal Block (ME1791A-F) has a 5-screw terminal block to connect to the twisted- pair lines and a female DB9 connector to connect to your computer port. 724-746-5500 blackbox.com 2of 6 #11220 3 of 6 5/2/2007 #11220 Short-Haul Modem-B 2W-A (SHM-B 2W-A) • Powered, point-to-point, 2-wire. • A pair of these l...
