1. OUTPUT POWER AND CHANNEL SEPARATION OF A
RADIOFREQUENCY DEVICE
The operating mode doesn’t influence the ouput power and the chanel spacing. There is
only one transmitter which is driven by identical input parameters concerning these two
parameters.
Channels spacing: 500 kHz
Output power (max): 500mW
A pseudo randomly ordered list of hopping frequencies (50 channels) is defined:
1, 15, 17, 4, 10, 6, 2, 11, 13, 18, 7, 12, 3, 9, 14, 5, 8, 16, 19,
20, 24, 37, 32, 30, 36, 21, 25, 31, 34, 22, 27, 35, 28, 26, 23,
33, 29, 38, 39, 43, 46, 42, 40, 47, 41, 45, 49, 50, 48, 44
2. FREQUENCY RANGE OF A RADIOFREQUENCY DEVICE
Hereby we declare that the maximum frequency of this device is:
902,75 MHz - 927,25 MHz
This is according the Core Specification (+ critical errata) for devices which will be
operated in the USA.
This was checked during the Qualification tests.
Other frequency ranges (e.g. for Spain, France, Japan) which are allowed according the
Core Specification are not supported by this device.
3. SYSTEM DESCRIPTION
The Repeater/Supervisor has two different and functioning modes:
- Supervisor mode connected to a PC through a wired serial link
- Supervisor mode connected to a PC through a radio frequency link
3.1. SUPERVISOR MODE CONNECTED TO A PC THROUGH A WIRED
SERIAL LINK
The system consists of a master with one or more slave (1 to 200 slaves).
The master name is “Repeater/Supervisor”.
There are two types of slave devices, named “GPS-COM” or “CSP-COM”
The function of the Repeater/Supervisor device (master) is to communicate with slave
devices (GPS-COM or CSP-COM) to exchange data synchronously through a radio
