DNA Message
In response to the Access Level 1 DNA command, the relay sends names of the
Relay Word bits transmitted in the A5D1 message. The first name is associated with
the MSB and the last name with the LSB. The SEL-701 Relay DNA message is:
<STX>
"STARTING","RUNNING","STOPPED","JAMTRIP","LOSSALRM","LOSSTRIP","46UBA","46UBT","13C7"
"49A","49T","THERMLO","NOSLO","TBSLO","ABSLO","*","*","0BDE"

<ETX>
where:
 <STX> is the STX character (02).
 <ETX> is the ETX character (03).
 the last field in each line is the 4-byte ASCII hex representation
of the checksum for the line.
 "*" indicates an unused bit location.
BNA Message
In response to the BNA command, the relay sends names of the bits transmitted in
the Status Byte in the A5D1 message. The first name is the MSB and the last name is
the LSB. The BNA message is:
<STX>"*","*","*","STSET","*","*","*","*","yyyy"
<ETX>
where:
 "yyyy" is the 4-byte ASCII representation of the checksum.
 "*" indicates an unused bit location.
The BNA command is available from Access Level 1 and higher.
