When issuing this command with the optional ‘,subset’ data field (without the square brackets), a one-line
response is provided. The subset field may be either CONF or GP. When CONF is specified for ‘subset’,
the following response is provided:
$>JSHOW,CONF,N,0.0,10.0,5,A,60W
This response is summarized in the following table:
Message Component
Description
$>JSHOW,CONF
Message header
N
‘N’ indicates no altitude aiding
0.0
‘0.0’ indicates the aiding value, if specified (either specified
height or PDOP threshold)
10.0
Residual limit for the $JLIMIT command, which is not supported
by the SXBlue II GPS.
5
Elevation mask cut-off angle, in degrees
A
AIR mode indication
60
Maximum acceptable age of correction data in seconds
W
Current differential mode, ‘W’ indicates WAAS mode.
When GP is specified for ‘subset’, the following is an example response provided:
$>JSHOW,GP,GGA,1.0
This response will provide the >$JSHOW,GP message header, followed by each message currently being
output through the current port and also the update rate for that message.

$JT
This command displays the revision of the receiver engine within the iSXBlue/SXBlue II GNSS:
$JT<CR><LF>
The receiver will return the following response, indicating that the receiver is an SX2g (‘g’ for global
differential operation) when in SBAS mode and SX2i when in Auto-Dif mode (‘i’ for internal differential
operation):
$>JT,SX2g
