Introduction Congratulations on your purchase of the RangeLAN2 791x Serial Adapter, the radio module that replaces RS-232 serial cables with wireless RF (Radio Frequency) technology. By attaching a pair of RangeLAN2 Serial Adapters to the serial port of any two devices, you can transmit and receive data without the use of wires. • RangeLAN2 754x Extension Point extends the cover- age area of an existing RangeLAN2 network.
There are two models of the RangeLAN2 Serial Adapter, the 7910 and 7911. The 7910 has 100 mW of output power, while the 7911 has 500 mW of output power. • System Requirements To begin using your RangeLAN2 791x Serial Adapter, you need the following minimum system requirements: At least one (1) device with a free RS-232 (serial) port (terminal, PC, etc.). At least one (1) other RangeLAN2 product. If the Serial Adapters are acting as a replacement for a serial cable, this additional RangeLAN2 product must be a second 791x Serial Adapter which will attach to a free.
• Figure 1 RangeLAN2 791x Serial Adapter Components. Quick Installation You may follow the quick installation and configuration steps if all of the following conditions are true: You will use all of the software default values. Ih 2015 Loader Manual. You are using two (2) RangeLAN2 Serial Adapters as a replacement for an RS-232 cable. You are using no more than nine (9) pairs of Serial Adapters in one location. • Attachment of the RangeLAN2 Serial Adapter Antenna 2.
Attach one end of an RS-232 cable to the RangeLAN2 Serial Adapter and the other end to a free serial port of a communication device, such as a terminal or a com- puter. Each RangeLAN2 791x Serial Adapter is preconfigured to use Domain 0. If you have multiple pairs of Serial Adapters and each pair consists of one Master and one Station, set each pair to a unique Domain number. Using the Domain rotary switch on the underside of the RangeLAN2 Serial Adapter, set each pair to a unique Domain number from 0-8 to ensure minimal interfer- ence. Wireless Topologies The RangeLAN2 Serial Adapter supports numerous wireless topologies. The following sections describe four (4) basic wireless configurations supported by the RangeLAN2 Serial Adapter: Point-to-Point, Point-to-Multipoint, Point-to-Point using RangeLAN2 Infrastructure, and Point-to-Multipoint using a RangeLAN2 Access Point as a Base Unit.
Point-to-Point In this topology, a pair of RangeLAN2 Serial Adapters are configured to exclusively communicate with each other. • In Figure 3 above, Serial Adapters 1 and 2 can communicate with each other, as can Serial Adapters 3 and 4. Even though all four units may be in range of one another and may “hear” the others’ messages, each unit will filter out messages not intended for it. • Point-to-Multipoint The RangeLAN2 Serial Adapter may also operate in a Point-to- Multipoint topology. This configuration provides added flexibil- ity, allowing one centralized unit, operating in Packetized mode, to communicate with multiple units placed in remote locations. When operating in Packetized mode, a central Serial Adapter may be programmed to send either directed messages or broad- casts to other Serial Adapters, by specifying the appropriate IP address and send mode.
• Figure 4 Point-to-Multipoint. • Point-to-Point Using RangeLAN2 Infrastructure You may also use your existing RangeLAN2 infrastructure and network to increase the range and flexibility of communications between Serial Adapters. A Serial Adapter configured as a Station may synchronize to a RangeLAN2 Access Point which has the same Domain and Security ID.
• Figure 5 Point-to-Point Using RangeLAN2 Infrastructure. • Point-to-Multipoint Using a RangeLAN2 Access Point as a Base Unit A Serial Adapter may communicate directly with a workstation that has either a RangeLAN2 ISA card, a RangeLAN2 PC card, or is on the same Ethernet segment as a RangeLAN2 Access Point.
• Figure 6 above shows a simple configuration of this topology. Desktop 1 is on the same network as a RangeLAN2 Access Point.
Serial Adapters 1 and 2 are configured as Stations and are synchronized to the Access Point, which is configured as a Master. Pass-through and Packetized Modes The Serial Adapter’s serial interface can be set for two kinds of operating modes: Pass-through mode and Packetized mode.
The format of the information presented to the unit’s serial port is dramatically different depending on which of these modes is selected. Understanding the Hardware Rotary Switches The RangeLAN2 Serial Adapter is designed for easy config- uration by setting two rotary switches located on the bottom of the unit. The rotary switches are shown in Figure 7 below. Use the switch setting tool, enclosed in the product package, to change the position of the rotary switches.
• Domain Switch Station/Master Switch Figure 7 Rotary Switches The Pairing Domain There is an additional feature associated with Domain 8 on the Domain Switch called the Pairing Domain. When the Pairing Domain is not used, two Serial Adapters will each send out a series of handshaking messages and exchange IP addresses to enable communication during boot-up. • when the unit is reset. This allows the user to permanently configure a pair of Serial Adapters to communicate exclusively with one another.
Follow these steps to permanently bind a pair of Serial Adapters: 1. Ensure that both units are turned off. • To reset the unit back to the default setting, manually set the Destination Address to 0.0.0.0 or reset the unit to factory de- faults from within the software configuration menu.
When using this feature, have only two Serial Adapters config- ured to Domain 8 on the rotary switch at any point in time. • The Serial LED on the left side blinks green when the Serial Adapter is transmitting data over the serial connection. Status LED Serial LED Radio LED Figure 8 Top Panel LEDs. • There are also four LEDs on the back panel of the RangeLAN2 791x Serial Adapter: The green Master LED, located between the DC power jack and the serial interface, is on steady when the unit is set as a Master. The yellow Sync LED, located between the DC power jack and the serial interface, is on steady when the unit is set as a Station and is synchronized to a Master. • Override LED Master LED Sync LED Figure 9 Back Panel LEDs.
• Serial Port Specification Figure 10 and the table below provide the specification of the 9- pin serial port located on the RangeLAN2 Serial Adapter. The Serial Adapter is wired as a DCE (Data Communication Equip- ment), like a modem. The unit is designed to connect directly to a DTE (Data Terminal Equipment), such as a computer or dumb terminal, using a straight-through RS-232 cable. • Figure 10 Serial Port Specification.
• Antenna Options The Serial Adapter is shipped with a standard directly-connected antenna. To install the antenna, screw it clockwise onto the antenna connector. Proxim sells several antenna alternatives, including higher gain omnidirectional and directional antennas. Each of these antennas ship with installation and mounting instructions. • 2.75” 2.10” Figure 11 Mounting Holes.
• You need to configure the RangeLAN2 Serial Adapter using the software menus if any of the following conditions apply: You plan to operate a Serial Adapter in broadcast mode. You want to set Security IDs on your Serial Adapters. You want to operate in Packetized mode. You need to change the software default values, includ- ing IP addresses. • Apply power to the Serial Adapter. When the unit is ready for operation, the letter “U” will be displayed on the terminal screen. Let the unit sit idle for one second and type “$$$”.
