FCC/ IC REQUIREMENTS FOR MODULAR APPROVAL In general, there are two agency classifications of wireless applications; portable and mobile. Portable – Portable is a classification of equipment where the user, in general, will be within 20 cm of the transmitting antenna. Portable equipment is further broken down into two classes; within 2.5 cm of human contact and beyond 2.5 cm. The LT2510P family is not agency approved for portable applications.
PAGE 3
ANTENNA REQUIREMENTS To reduce potential radio interference to other users, the antenna type and gain should be chosen so that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication. WARNING: This device has been tested with an U.FL connector and the above listed antennas. When integrated into the OEM’s product, these fixed antennas require professional installation preventing end-users from replacing them with non-approved antennas.

LT2510 Wireless Module HARDWARE INTERFACE PIN DESCRIPTIONS RXD and TXD The LT2510 accepts 3.3 VDC TTL level asynchronous serial data from the OEM Host via the RXD pin. Data is sent from the transceiver, at 3.3V levels, to the OEM Host via the TXD pin. Test Test Mode - When pulled logic Low before applying power or resetting, the transceiver’s serial interface is forced to 9600, 8-N-1 (8 data bits, No parity, 1 stop bit): regardless of actual EEPROM setting.
PAGE 10
LT2510 Wireless Module THEORY OF OPERATION SERVER/CLIENT ARCHITECTURE The LT2510 utilizes a server-client network architecture to synchronize the frequency hopping. Each network must have one radio configured as a Server and all other radios configured as Clients. When a radio is configured as a Server, it will transmit a beacon at the beginning of each hop.
