MT2000-0200-1 Rev f (10-2007)
DCN0160 21
6.2 Operating Modes
The MT2000 transmitter with DE option can be operated in two ways, selectable using the setup menu of the instru-
ment:
1. DE Digital Mode: In this mode the transmitter output is strictly digital and uses the Honeywell DE Protocol,
which modulates the loop current On and Off to transmit digital information per above Class Conformance defini-
tion.
2. Analog Output Mode: In this mode the Honeywell DE Digital Output is disabled and the transmitter is in a stan-
dard 4-20 mA output mode. In this mode no digital communications are available.
NOTE: The current MT2000 Honeywell DE does not support database information. Ensure that the DB parameter
in the DE menu is set to OFF.
7. HART PROTOCOL INTERFACE OPTION
The MT2000 transmitter is available with a HART Protocol Option. In order to obtain proper communications a mini-
mum 250 ohm load in series with the loop wiring is required. The HART protocol option allows for the use of the fol-
lowing communicators. Other communicators and HART protocol interfaces can also be used, subject to their capa-
bilities of supporting the GENERIC mode.
7.1 HART Communicator
The MT2000 is not a known product with a HART DEVICE DESCRIPTION. The communicator will come up in GE-
NERIC mode. This mode allows a limited number of commands. The main commands available are:
READ OR WRITE OUTPUT UPPER RANGE & LOWER RANGE VALUES
READ OR WRITE OUTPUT DAMPING VALUE
READ OR WRITE TRANSMITTER TAG, DESCRIPTION, MSG, DATE
PERFORM OUTPUT DIGITAL TRIM
TEST LOOP OUTPUT
SET POLLING ADDRESS
7.2 HART AMS
7.2.1 Compatibility
Software: The supporting software (“Resource Files”) for AMS was designed for release with AMS 6.0.
Device: Since all K-TEK’s HART compatible devices are based on the Universal (Generic) Model, all versions of the
MT2000 (assuming it is equipped with the HART option) will operate under AMS, even those shipped before the re-
lease of AMS Version 6.0.
Note for Users with AMS Versions Prior to 6.0: If you do not have AMS version 6.0, the MT2000 will still function as
a Generic device, with all of the functionality normally available from a HART perspective.
7.2.2 Resource Files
Availability: The Resource Files necessary for the MT2000 to be recognized as an AMS aware are located on AMS
Software CDs beginning with version 6.0. AMS customers with “Foundation” support should automatically receive
version 6.0 if they purchased a previous version.
Installation: To install the necessary Resource Files for use with the MT2000, follow the instructions provided with
your version of AMS to “Add Device Type”. The device will be found as MT2000 under Manufacturer/K-TEK.
Once the Resource Files for the MT are successfully installed (you may have to restart AMS), the device should ap-
pear under “Device Connections”, or equivalent, depending on your version of AMS.
