SDM-650B Satellite Modem Trojan Interface
Rev. 5 G–17
G.6.1.1.1 Start Character
A single character precedes all messages transmitted on the remote link. This character flags
the start of a message. This character is:
• “<” for commands
• “>” for responses
G.6.1.1.2 Device Address
The device address is the address of the one satellite modem which is designated to receive
a transmitted command, or which is responding to a command.
Valid device addresses are 1 to 3 characters long, and in the range of 1 to 255. Address 0 is
reserved as a global address which simultaneously addresses all devices on a given
communications link. Devices do not acknowledge global commands.
Each satellite modem which is connected to a common remote communications link must
be assigned its own unique address. Addresses are software selectable at the modem, and
must be in the range of 1 to 255.
