DATALOGIC PROPRIETARY INFORMATIONS
Introduction
The StarModuleSLC910 is an FSK RF half-duplex transceiver working at 910MHz, made to be
installed on fixed or mobile devices.
Digital interface
Digital Interface with host system:
Data communication with host is implemented using a UART @38400, N, 8, 1
Control is implemented using IDLE/RX line and receiving Carrier Detect indication .

RF interface
StarModuleSLC910 has 50 Ohm impedance on RF out in TX and RX mode, therefore impedance
matching is required for antenna system of host.
Care must be taken for the proximity of conductive materials or the user’s hand that will cause a
mismatch of the antenna, decreasing the transceiver RF characteristics.
Moreover, care must be taken to ensure that the host system doesn’t have spurious emissions in the
range 910MHz+/-100kHz, that could cripple receiver sensitivity: it is advised to put a ground plane
under the RF module and to filter the power supply.
Noisy parts, like system buses, must be shielded in order not to irradiate spurious fields.
