16. Reading 3M™ iD Markers
The operator can retrieve the data from the iD marker by pressing Read  [SK] on the 
Marker Locate display.
The receiver tip should be lowered to the ground to reach maximum read depth.
If more than one 3M
™ iD Marker of the same utility is detected, the receiver will read 
the first marker and display the data from the marker.
The fourth yellow command key will be labeled 
“Read Next”. Press this key to extract the data from 
the other marker.
All the information retrieved from the marker, including the date and time read, is 
saved into the ‘Read History’ file of the receiver. If a hand-held GPS device is used in 
conjunction with the receiver, coordinates will be saved into the "Read History" file also. 
(See  17. Reviewing Marker Read/Write History.)
17. Reviewing Marker Read/Write History
A. Read History
The Read History mode is a historical file of all information that has been read from 
targeted markers (100 memory locations).
Menu/OK [5:Toggle to MAIN MENU] + Data/Template [SK:2] + Read History [SK:a]
The Read History screen displays the date and 
time that each marker was read, and its unique 
identification (serial) number.
• Select the marker data to be viewed by pressing 
the up/down arrows [SK]
•  Press  Marker Details [SK] to view all data that 
was retrieved from the marker.
•  Press  Read History [SK] to return to list or  
press  Exit [SK] to return to Data/Template   
review display. 
						

							 56 78-9000-0192-2 Rev D
B. Write History [SK]
Menu/OK [5:Toggle to MAIN MENU] + Data Template [SK:2] + Write History [SK:b]
• Select the marker data to be viewed by pressing 
the up/down arrows [SK].
•  Press  Write Details [SK] to view all data that was 
sent to the marker.
•  Press  Write History [SK] to return to the list of 
written data.
•  Press  Exit [SK] to return to Data/Template   
review display.

18.  GPS Compatibility Operation
A. Capturing the GPS Coordinates (Capture Mode / Mode 1)
Menu/OK [5:Toggle to MAIN MENU] +  [SK:3] + NMEA
If the GPS device is not configured properly, there is an error communicating with the 
receiver, or the GPS device has not acquired enough satellites to pinpoint the location, 
the receiver will display the message “Insert External Device” .
When the receiver is communicating with a GPS 
device, the LAT and LONG coordinates received 
from the device will appear on the marker locate 
display.
Step 1.  Locate a marker (See 13.C.  Single Marker Locate)
Step 2.  Press Read [SK]
The information from the 3M
™ iD Marker, as well as the GPS coordinates, will display 
on the receiver display. This information is saved automatically in the Read Marker 
History. (See 17. Reviewing Marker Read/Write History.)
If the marker is a passive marker (rather than iD) the receiver will display “No iD 
Marker Found”. The GPS coordinates of the attempt to read the non-iD marker are 
stored in the Read Marker History as serial number # 0000-0000-0000. The marker 
details will indicate  “not an iD marker”, but will display the GPS coordinates.

B. Sending 3M™ iD Marker Data to GPS                                 
(Capture-Transmit Mode / Mode 2)
Menu/OK [5:Toggle to MAIN MENU] +  [SK:3] + GIS
Receivers that have marker locating capability (indicated by ‘iD’ in the model number) 
can be configured to send 3M
™ iD Marker data directly to some GPS devices. When 
an iD marker is located and read, the information read from the iD marker with feature 
and attribute data is sent to the GPS device and is stamped with latitude, longitude and 
date/time data. The data acquired during this logging process can be uploaded to GIS 
mapping software. For more information and detailed instructions pertaining to specific 
GPS devices, refer to www.3M.com/dynatel  for GPS instruction sheet.
C. Path Mapping with GPS
The 3M Dynatel™ Cable and Pipe Locators 2500 Series are compatible with hand-
held GPS devices and now have the ability to map the path of underground target 
facilities. While measuring the depth to the target, the technician can automatically log 
the coordinates of the path to the GPS device. These logged points contain the Trace 
template that can have valuable information regarding the facility (owner, utility, size, 
etc.) and the method used to find the path (frequency, current, and measured depth).
In order to transmit the path information to a GPS device, the GPS device has to have 
the ability to accept information on one of its com ports at 4800 Baud. Using the manual 
supplied with the GPS device, configure the com port of the GPS device to communicate 
with the receiver.

1. Creating Trace Templates
The easiest way to create a Trace template is using the 3M™ Dynatel™ PC 
Tools Software. (Software available for no charge at www.3M.com/dynatel  - 
2550/2573/2250M/2273M/1420 Locator PC Tools xx.x.x (EXE xx.xMB).
•  Create a TRACE template.
•  Save and download the template to the receiver.
Up to four Trace Templates can be stored on the Receiver.
Each Trace template is limited to 132 user editable characters.
The trace template appears in table format: two columns with six lines.
The first column is limited to 8 characters and the second column is lim\
ited to 14 
characters. In addition to the 132 character table, the receiver will se\
nd a sequence number, 
the frequency, the measured depth of the conductor, and the current to the GPS device.
2. Select Com Port Setting
Menu/OK [5:Toggle to MAIN MENU] +  [SK:3] + GIS [SK] (or PDA [SK])
If the GPS device has the ability to send NMEA coordinates on its com port and has the 
ability to receive information at 4800 baud, set the receiver’s com port to GIS.
If the GPS device only has the ability to receive information, set the com port of the 
receiver to PDA mode.
Log Prompt = On: Before the receiver returns to locate mode, a verification display 
will pop up on the receiver with the trace template information that will be sent to the 
GPS device. This information can be modified and confirmed. Press Menu/OK  [5] to 
send to GPS device.
Log Prompt = Off: When the receiver returns to locate mode, the trace template and 
locate information will be sent automatically to the GPS device.
3. Sending Path Information to GPS Device
Step 1.  Establish communication with the GPS device.
Step 2.  Set COM port on receiver.
Step 3.  Locate target utility.
Step 4.  Measure depth to target utility.
 
− If Log prompt is activated, when the TRACE button is pressed (or after a 
five second delay), a display will appear that displays the path information.
Step 5.  Press Menu/OK [5] to send the information to the GPS device, or Exit  to 
prevent the exchange.
For more information refer to the software release notes at www.3M.com/dynatel.
