Chapter 5 

Submetering end devices transmit meter and status information after ten 
pulses are received or after approximately sixty minutes since the last 
transmission, whichever comes first. Messages from security end-devices to 
the gateway adhere to the format defined following.

Note: The format of EchoStream messages will vary depending on the message type. 

Always check the message class byte before attempting to determine the 
contents of a message.

Note: A number in parentheses following a data signifier represents the number of bytes 

the item contains.  For example, unique ID (4) is a 4-byte field.

[0x72] – Header for inbound complete message.

[LEN] – Message length, excluding checksum.

[UID (4) originator] – Unique ID of device originating message.

[UID (4) first hop] – Unique ID of the device which received 

original message, as well as the signal level and margin. If the 

UID begins with 00, then the RF gateway is the first hop; if the 

UID begins with 01, then the repeater is the first hop.

[Trace count (1)] - Number of trace unique IDs that follow. The 

default is zero, indicating no trace data.
