HN-2010 Repeater HN-2010 Repeater Introduction The HopNet Repeater (HN-2010) provides extended range capability between two HopNet networks. This repeater capability allows HopNet networks to be “daisy- chained” in series to send and receive data from remote locations that would otherwise be outside the coverage area of a single network. -

Page 16: Power
Power Connector Proper placement of the external antenna is important since two modems inside the HN-2010 will be operating simultaneously. Be sure to physically separate the antennas from each other because the output transmission of one side of the repeater may interfere with the reception of the other. -

Page 23: Modem Commands
Configuring the Network Modem Commands The HopNet is configured and controlled through a series of commands. These commands are sent to the modem directly when the modem is in Control Mode or when the modem is in Data Mode if the escape sequence is enabled. The command syntax is the same for either method, a one- or two-letter command followed by one or more parameters. -
Page 24: Serial Commands
Configuring the Network Serial Commands These commands affect the serial interface between the modem and the host. The default settings are 9600 bps and protocol mode 0. Command Description sd[?|00..FF] Set Data Rate Divisor Data Rate Divisor (hex) 1200 bps = 2400 bps = 9600 bps = 14400 bps =... -
Page 25: Set Protocol Mode
Configuring the Network Set Protocol Mode Enables the base station to operate in a multipoint network. Depending on the user application, more or less acknowledgment may be desired by the application. Remotes can operate in transparent mode even though the base station is operating in one of the nontransparent modes. -
Page 26: Network Commands
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[?|0|1] Set Transceiver Mode 0 = remote (default) 1 = base station wd[?|1-3f] (base Set Default Handle only) Used to override automatic handle assignment by the base station 30 = default... -
Page 27: Enable Global Network Mode
Configuring the Network Enable Global Network Mode For networks with multiple base stations, remotes are ordinarily only able to link to one base station, set by the hopping pattern. Mode 1 enables the global mode that allows remotes to link to any base station they can hear, acquiring whatever hop pattern is required. -
Page 28: Set Range Optimization
Configuring the Network Set Range Optimization This command applies an adjustment factor to the over-the-air timing of remotes to compensate for the effects of propagation delay at long ranges. The default setting of 00H is suitable for ranges of 0 to 0.8 miles (1287 m), with optimal performance at 0.1 miles (162m). -
Page 29: Protocol Commands
Configuring the Network Protocol Commands These commands can be used to tune the transceiver for optimum transmission of data across the RF link. For most applications, the default values are adequate. Command Description pe[?|0-4] Set Alternative Frequency Band 0 = FCC/ETSI operation. (~2401 – 2471MHz) (default) 1 = France (~2448 –... -
Page 30: Set Alternative Frequency Band
Configuring the Network Set Alternative Frequency Band When set to 1, limits the operating RF channel set to the 2448 to 2473MHz frequency band for compliance with French regulatory standards. When set to 2, sets appropriate operation for Spain. When set to 3, sets appropriate operation for Japan. This setting should be set to 0, for FCC-compliant operation in the US (this is the default). -
Page 31: Set Maximum Number Of Remotes (Base Only)
Configuring the Network Set Maximum Number of Remotes (base only) This parameter limits the number of remotes that can register with a given base. The default is 62 remotes which is the maximum number of remotes that can be registered with a base at one time. -
Page 32: Set Base Slot Size (Base Station Only)
Configuring the Network Set Base Slot Size (base station only) Sets the amount of time allocated for transmission on each hop for the base station time slot in 69.4µs increments, corresponding to 4 bytes per unit. Maximum value is 34H which corresponds to 208 bytes. If using a protocol mode, attempting to send a packet with a length longer than this setting will cause the packet to be discarded. -
Page 33: Status Commands
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) zc[?|0..2] Set Escape Sequence Mode 0 = disabled 1 = once after reset (default) 2 = unlimited times Read factory serial number high byte. -
Page 34: Read Factory Serial Number High, Middle And Low Bytes
Configuring the Network Read Factory Serial Number High, Middle and Low Bytes. These read only commands return one of the three bytes of the unique factory-set serial number, which are also visible in the startup banner. Set Duty Cycle Allows reduced power consumption by having a remote wake up only every 2 hops to receive and transmit. -
Page 35: Memory Commands
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. -

Page 37: Guidelines For Installation
Configuring the Network Guidelines for Installation When installing your system, always consider the following points: • Directional antennas are best for remote unit sites. They may increase the cost, but they confine the transmission path to a narrow lobe and minimize the interference from nearby stations. -
Page 39: Typical Hopnet Applications
This common application consists of a central host and remote terminal units or other data collection devices. The automatic repeat requests (ARQ) and acknowledgments inside the radio are transparent to the computer system.

Page 40: Troubleshooting
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. -
Page 41: Common System Problems
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. Problem System Checks Unit is inoperative 1. Check for proper DC voltage at the power connector. -
Page 42: Guidelines For Reducing Interference
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. -
Page 43: Guidelines For Avoiding Terrain Obstructions
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. -
