FCC and IC: This device complies with parts 15 and 90 of the FCC rules. This device must be operated as supplied by Xetawave LLC. Any changes or modifications made to the device without the express written approval of Xetwave LLC may void the user’s authority to operate the device. Caution: The model number XETA1 has a maximum transmitted output power of 1500mW in the 150 to 174 MHz bands. It is recommended that the transmit antenna be kept at least 42.
WARNING These radio systems shall be installed by a RF/radio professional familiar with the applicable rules. Installation of all antennas shall be performed in a manner that will provide at least the MPE Distance from the direction of maximum radiation, to any physical space where humans may exist, and consistent with the settings in the applicable antenna installation compliance section.
reduce data rates, change modulation methods, increase power levels, change frequencies, or enact other modifications to maintain the best data link possible given the conditions iaw the licensee’s allowed conditions. The design of the radio also includes a physically small size, low weight and very low power consumption while maintaining a robust design over extremes in environmental conditions. XETA1 The XETA1 is the 100MHz version of the Xeta family.

The four mounting holes have a 0.093” diameter finished opening 0.100” from the edges designed for a #2-56 screw. The clearance height of the radio is 0.210” shield height, .103” PCB height, 0.070” back side height. (The connectors are on the side with the shield.) Heat Sink contact is on the opposite side of the connectors/shield at the lower left corner (back side as shown above).

The radio pin out may be connected to two DB9 connectors according to the following pin diagram: Depending upon configuration, before connecting to a computer, each serial port may need to pass through a 3.3V TTL to RS232 converter such as this SerialComm TTL-232-33P. The radio is either manufactured for a high speed 3.3V interface or for a conventional speed RS-232 interface. In order to power the radio, 7.5V DC must be applied across pins 7 and 10.

Option “2” is used only with the Ethernet option and should be left as “Raw” for normal radio operation. The diagnostic serial Baud rate is shown for reference but is not adjustable. Option “3” is selected to modify the output clock that is synchronous to the data serial port. The output clock may be used to synchronize the user hardware to the radio clock for ease of serial port interface but is not required.
RF Configuration This menu allows for the selection of the frequency characteristics of the radio and can be accessed from the main configuration menu by selecting menu option “1”.
The final RF input is the maximum distance between master/slave radios. This distance determines the propagation delay so that a short distance will have less delay and a higher throughput. The higher that this parameter is, the lower the data speed but setting this parameter to a smaller value than the actual separation can result in higher error rates. Important: this parameter must be the same for all radios in a given network.
Bit Rate and Modulation Configuration The various data rates may be chosen from the main menu by selecting option “2” from the main menu. Multiple rates may be selected so that the radio will attempt to operate at the highest data rate possible, but if the signal begins to drop too low, then the data rate will drop so that performance is improved. Alternatively, if only one rate is selected, then only that rate will be used and if the signal quality drops, the link between the radios may drop.
The selection of data rate and modulation should be made with knowledge of the expected signal level. Below are typical sensitivity values for different operating modes. Sensitivity (10-4BER) Uncorrected (No ECC) -111dB @ 8.0 kbps (12.5kHz BW) 2-level GFSK -104dB @ 16.0 kbps (12.5kHz BW) 4-level GFSK -112dB @ 12.0 kbps (12.5kHz BW) QPSK 1 -118dB @ 18.
Network Configuration The Network Configuration defines the radio personality as Master, Slave, or Repeater. There must be one Master on a network. For a point-to-point network, there must be one slave with optional repeaters. On a point-to-multipoint network, there must be at least one slave.
Maximum Payload Size for Master The Maximum Payload Size for Master/Slave parameters specify the maximum number of payload bytes per transmitted packet, separately for the Master and Slave radios. For example, in an application requiring greater throughput from the master to the slave, set the master parameter to the maximum value (1024) and the slave parameter to a lower value (minimum 16). The time saved transmitting smaller packets in one direction will increase throughput in the other direction.
a. Master, Repeater, or Slave (one master per network) b. Network operation of “point-to-point” or “point-to-multipoint” c. Network address that is shared by all radios on the network d. Radio address of this radio (“1” if master) e. Address of radio upstream (closer to the Master) f. Address of radio downstream (farther from the Master) g.
