Description Description
Ground Signal and Chassis Ground
Transmitted Data Serial Data Input
Received Data Output for received serial data
Control line can be used as a backup method for entering
Command mode:
(0V) – Maintenance Mode; (3.3V) – Data Mode
Data Terminal Ready
An internal 100K pull-up enables Data Mode if this
signal is left unconnected. Maintenance Mode is also
accessible by transmitting an escape sequence.
Used to control transmit flow from the user to the radio:
Clear to Send (0V) – Transmit buffer not full, continue transmitting
(3.3V) – Transmit buffer full, stop transmitting
In sleep mode, all radio functions are disabled consuming
less than 50µA. An internal 10K pull-down wakes up the
radio if this signal is left unconnected. At wake up, any
Sleeps/wakes radio user programmed configuration settings are refreshed
Receive only from flash memory, clearing any temporary settings that
may have been set:
(3.3V) – Sleep Radio; (0V) – Wake Radio
As an option could be used as TTL Input Line 1.
Used by remotes to indicate that the remote has success-
fully acquired the signal from base station:
Data Carrier Detect
(0V) – Carrier detected (synchronized)
(3.3V) – No carrier detected (not synchronized)
pin 15
Gates the flow of receive data from the radio to the user
on or off. An internal 10K pull-down enables data receive
if this signal is left unconnected. In normal operation, this
Request to Send
signal should be asserted:
(0V) – Receive data (RxD) enabled
pin 1
(3.3V) – Receive data (RxD) disabled
Used to control transmit flow from the user to the radio:
Data Set Ready (0V) – Receive buffer has data to transfer;
(3.3V) – Receive buffer is empty
