Configuring the Network Introduction The HopNet 10 Series family of products provides reliable wireless connectivity for point-to-point applications. HopNet products employ frequency hopping spread spectrum technology. This technology ensures: • Maximum resistance to noise • Maximum resistance to multipath fading • Robustness in the presence of interfering signals The HN-110 is NEMA 4X weatherproof versions of the HopNet product line.
Configuring the Network Flexible Power Management You can place the transceiver module in a power-save mode, which enables smart power management. Smart power management allows a remote unit to drop into a lower current standby mode during transmission or receiving gaps. This feature also allows Hopnet products to be used in various countries where the output power requirements may vary due to regulation.
Configuring the Network Getting Started A pair of HN-110s is set up by performing the following steps: • Install the HopNet Wizard configuration program on a PC • Connect the HN-110 to the PC • Run a communications test These steps are described in detail below. Other steps you may want to perform include: • Change the baud rate Refer to the Configuring the Network section of this manual for details on these steps. Install the HopNet Configuration Wizard on a PC.
Configuring the Network Connect the other end of the serial cable to the serial adapter box. Connect the end of the cable from the HN-110 to the small serial adapter box. Plug the RJ-45 type connector from the HN-110 into the serial adapter box. Connect power to the HN-110 by plugging one end of the wall-mount power supply into the serial adapter box and the other end into a wall outlet. A green LED on the serial adapter box will turn on indicating power is present. Green LED is on when power is applied.
Configuring the Network The Serial Adapter Box The HN-110 remote interfaces with the user’s hardware through a serial adapter box. The interface adapter supplies power and signal to the remote unit. The interface to the remote unit is a standard RS-232 DB-9 serial interface. To have all functions of the HN-110 available, including configuration and hardware flow control, the eight signal lines must be connected. The HN-110 serial connector is set up as a DCE device.
Configuring the Network Remote Pin-Out, RS-232 Pin Number Signal Type Description 1 DCD Output Data Carrier Detect. For remotes, DCD indicates that the remote has successfully acquired the hopping pattern. 2 RXD Output Output for received serial data. 3 TXD Input Input Serial Data to be transmitted 4 DTR Input Data Terminal Ready. Sleep/ wakes radio transceiver. 5 GND - Signal and Chassis Ground 6 DSR Output Data Set Ready. Response to DTR. 7 RTS Input Request to Send.
Configuring the Network Guidelines for Installation When installing your system, always consider the following points: For systems with constant interference present, you may need to change the polarity of the antenna system and reduce data streams. Groups of short data streams are more reliable and have a better chance of success in the presence of interference than do long data streams. Systems installed in rural areas are least likely to encounter urban interference.
Configuring the Network Configuring the Network WinCOM24 Window The program WinCOM24 window can be used to enter these other configuration commands. Please be aware that an improper commands or a wrong combination of configuration values can affect the radio’s performance. When the window is opened, the sign-on banner is displayed. The banner indicates the radio firmware version, whether the radio is operating as a base or a remote and the unique factory serial number of the radio module in the HN-110.
Configuring the Network Configuration parameters are sent to the radio by entering them in the WinCom window after the “>” prompt and pressing the Enter key. The radio will echo back the new parameter value indicating the parameter was successfully set. If an invalid command or value is enter, the radio will respond with “Error.” Until the command to save the parameters is issued, the new parameters will only be valid until power is cycled or DTR is toggled.
Configuring the Network Configuration Commands The HN-110 has a wide selection of configuration parameters that can be modified using one or more of the configuration commands. The commands can be grouped into five categories based on what they do. The five sections are: • Serial Interface Commands • Network Commands • Protocol Commands • Status Commands • Memory Commands Each command is described in detail below. In the descriptions, brackets ([,]) are used to denote a set of optional arguments.
Configuring the Network Network Commands Network commands are used to set up a HopNet network and to set radio addressing and configuration. Command Description wb[?] Set Transceiver Mode 0 = remote (default) 1 = base station wh Factory serial number high byte. wm Factory serial number middle byte. wl Factory serial number low byte. Set Transceiver Mode Read modem operation as either base station or remote. Default is remote. Read Factory Serial Number High, Middle and Low Bytes.
Configuring the Network Status Commands These commands deal with general interface aspects of the operation of the HopNet. Command Description zb[?|0|1] Banner Display Disable 0 = disabled 1 = enabled (default) zh? Read factory serial number high byte. zm? Read factory serial number middle byte. zl? Read factory serial number low byte.
Configuring the Network Memory Commands The user is able to store a configuration in nonvolatile memory, which is loaded during the initialization period every time the radio is powered up. Note that changes to the serial port baud rate- from recalling the factory defaults or recalling memory will not take effect until DTR is toggled or power to the radio is cycled. Command Description m0 Recall Factory Defaults m> Store Memory Recall Factory Defaults Resets the HopNet to its factory default state.
Troubleshooting Troubleshooting Overview Introduction Troubleshooting the HopNet products is not difficult, but it does require a logical approach. It is best to begin troubleshooting at the base station because the rest of the system synchronizes to it. If the base station has problems, the entire network will be compromised. This chapter provides troubleshooting information for your HopNet products.
Troubleshooting Common System Problems The following table offers suggestions for resolving some common system problems that the operator may experience from the radio system. If problems persist, contact the factory for further assistance. 20 Problem System Checks Unit is inoperative 1. Check for proper DC voltage at the power connector. 2. Momentarily remove and reapply power. No Carrier Detect at remote units or intermittent 1. Check for secure interface connections at the transceiver. 2.
Troubleshooting Guidelines for Reducing Interference Introduction The transceivers share the same frequency spectrum with other services and other Part 15 devices in the US. Because of this, you may not achieve 100 percent error free communications in a given location. You should also expect some level of interference.
Troubleshooting Guidelines for Avoiding Terrain Obstructions The HopNet transceivers operate in the 2.4 GHz frequency band. While this band offers many advantages over the VHF band for data transmission, it is also more prone to signal attenuation from obstructions such as terrain, foliage, buildings and anything else in the transmission path.
