Introduction
The base station operation can be modified by the use of links (see
Table 6.1) and programmable settings.
The base station can be configured for operation in the following basic
modes of operation:
■
Line-controlled base: The base station transmit audio and key is derived
via the system interface. Audio response is link-selectable.
■
Talk through repeater (voice): The receiver audio is directly connected
to the transmitter and the transmitter is keyed by the receiver gate.
Audio response in this mode is software-selectable.
■
RF modem: Data on the serial interface is connected to the transmitter
and the receiver.
■
Data repeater: The received data line is connected to the transmit data
line. receiver gate and transmitter key signals are not used.
