1. 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. The RangeLAN2 791x can support several data rates and uses the same patented 2.4 GHz frequency hopping spread spectrum (FHSS) technology as found within Proxim’s aw

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 RS-232 port on another device. The Product Package Each RangeLAN2 791x Serial Ada

2. 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. ❑ 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. Follow the steps below to install two RangeLAN2 791x Serial Adapters: 1. Firmly screw the antenna onto its connector in a clock- wise rotation. The ant

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. Perform this step with both Serial Adapters. 3. Each RangeLAN2 791x Serial Adapter is preconfigured to operate as a Station. Therefore, before two Serial Adapters will communicate, one must be set as a Mas- ter. Using the Station/Master rotary switch on the undersi

4. 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. If you decide to use Domain 8, refer to Chapter 5 for information concerning this switch setting’s role in the Pairing Dom

3. 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. Figure 3

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. Since this topology establishes a one-to-one, Master- Station relationship between two Serial Adapters, it acts as a wireless substitute for an RS-232 cable in a wide variety of applications. Using the TCP/IP protocol as the transport mech

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. The Packetized

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. Two Serial Adapters which are positioned out of range of one another, can be set as Stations so that each will synchronize to a RangeLAN2 Access Point. Then, the Access Point(
