XStream‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v5.x00 [2006.02.24]
Configuration
Global Connection
AT Command Mode
AT command mode is used for all commands on base and remote modems. Binary command
mode is not available when MD = 1 or 2.
The base is in AT command mode when not engaged in an exclusive connection with a remote.
No AT Command Mode sequence is needed. When a base modem is connected to a remote
modem, the AT Command Mode sequence is used to enter AT command mode. The connection
with the remote is maintained. Care should be taken that the CE (Connection Inactivity) timeout
does not occur while in AT Command Mode.
The remote must use the AT command sequence to enter AT Command Mode. When a
connection exists with a base modem, the connection is maintained. Care must be taken that the
CB (Connection Duration) timeout does not occur while in AT Command Mode.
As of firmware version, 4.30, a faster method is available for entering AT Command Mode. If the
BT and AT parameters are set to 0, BT (Guard Time Before) and AT (Guard Time After) times are
set to 6 milliseconds.
Beware that this will also mean that AT Command Mode cannot be entered by manually typing
the AT command sequence (usually “+++”), because the AT time will occur faster than the
characters can be typed.
Auto Configuration
When enabling Multi-Streaming Modes (by setting the MD (RF Mode) parameter to 1 or 2), other
parameter values are automatically modified to support the mode. For example, when the MD
parameter is changed to 1 or 2, the RR parameter is changed to 0x0A (hex). The modification
only occurs if the RR parameter is 0 (its default) before the MD command was executed. If any
other value is found for the RR parameter, the RR parameter will not be changed. Auto
configuration occurs every time the modem is powered-up.

* The system requires that each remote have a unique address. The automatic address is based on the serial
number and is not guaranteed unique, although the chances for a duplicate address are 1 in 16,000. No method
currently exists for detecting & reassigning duplicate remote addresses.
The base modem can connect to all remote modems (to send a broadcast message) by
connecting with a DT address of 0xFFFF (hex). There will be no acknowledgements from the
remote radios and each packet from the base will be sent RR times. A remote cannot send
messages to a base during a global connect.
The CGP and DGP packets will be sent RR times to begin and end the global connection
respectively. The connection can be terminated by CE, CB timers, DI3 or ATDC Command as any
other connections.
