This device complies with parts 15 and 90 of the FCC rules along with IC RSS-210 and SRSP-501. 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 XETA4 has a maximum transmitted output power of 2000mW in the 406.1 to 430 and 450 to 512 MHz bands. It is recommended that the transmit antenna be kept at least 97.
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. Introduction The Xeta Radio family is a small form-factor data radio designed for transmitting low to moderate speed data across distances of up to 100 miles. Thus, this radio family has a much longer range than Wi-Fi or other short distance radios, but at a lower data rate capacity.
Any antenna from a reputable manufacturer with desired bandwidth, gain/pattern coverage, and have an input surge impedance of approximately 50 ohms can be used with the Xeta4. Since professional installation is required, standard RF connectors are used. Adapters or custom coaxial cables may be required to connect the radio output connector to the desired antenna, provided the appropriate requirements are met. US/FCC antenna compliance FCC Antenna Parameters vs.
Canada, in SRSP-501, requires a minimum of 9 dBd or 11.15 dBi antenna gain and a maximum of 125W ERP. Table 2 summarizes the power settings for the antenna examples listed. Table 1.

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, 4.5-7.5V DC must be applied across pins 7 and 10.

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. The baud rate for the data port can be changed by selecting “0” and the various speeds will be displayed: Data Serial Bit Rate This parameter specifies the serial bit rate in bits/second for the data port.
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”.
separation can result in higher error rates. Important: this parameter must be the same for all radios in a given network. Maximum Separation This parameter specifies the maximum distance in km between radios. Larger values result in lower throughput due to time allocated for propagation delay.
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.
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. Set the data block size sent downstream and upstream 3) Set the RF data rate speed and modulation method 4) Set the transmit power 5) Set the distance between the radios for worst case propagation delay.
