Meriam 4150X ATEX I.S. Certified HART Communicator - Manual (Page 28)

24
In general, the Generic HART mode operates similarly to its device specific DOF counterpart (see HART
Communication section of this manual for more details). However, the 4150 / 4150X does not display Device
Specific related communication menus or options when in the Generic communication mode. For example, the
Zero and Sensor trim menu options (normally executed by Device Specific commands) are not displayed for
pressure transmitters without DOF support. Please see the Download Site section of this manual for
information on downloading the latest Device Specific DOF files to your 4150 / 4150X.
Updating the 4150 / 4150X Firmware and DOFs
Overview
Firmware upgrades and new DOFs can be downloaded via the Internet in either of two ways. The first way is
to use the DPC Manager utility (shipped with each 4150 / 4150X or downloaded from the DOF Download
Site) on a PC with Internet access to download files from the DOF Download Site automatically and then
update the 4150 / 4150X. The second way is to use the DOF Download Site to download the needed files to
the host PC and then use the DPC Manager utility to coordinate the update of the 4150 / 4150X. The
Download Site enables users to stay current as new DOF’s or revisions of existing ones are posted.
Automatic email notices of new DOF postings are sent to all users who have logged on to the Download Site
and registered their email address under “Subscriber Options.” Firmware updates are free of charge. DOFs
are available by subscription.
A list of currently available DOF’s for HART device communication can be viewed at the

Who has access to the Download Site?
All 4150 / 4150X customers can purchase a subscription to the DOF Download Site. These
customers may download any published file from the site to their host PC upon entry of the proper
authenticating codes (User Name and Password shipped with each unit). Contact Meriam at 216-
281-1100 or [email protected] for more information and to purchase subscriptions.
PC Requirements for Download Operations
Meriam recommends IBM compatible Pentium I PCs or higher for download operations. The PC
should have an available RS-232 port, minimum modem speed of 28K and access to Internet service.
USB ports can be used with USB to serial adapters as well. The RS-232 port must not be shared with
other software applications during update operations.
Preparing the 4150 / 4150X
All models come ready to connect to an IBM compatible PC. Connect the supplied Communication /
AC Adapter Dongle (P/N Z4150-10A) to the unit. Connect the Dongle to the PC using the supplied
six-foot male DB-9 to female DB-9 cable (P/N ZA90047-00052). Similar cables are acceptable.
Provide power to the Dongle using the supplied AC Adapter (P/N Z9B000007). The unit is ready for
download operations.
Warning: To avoid damage to a PC serial port, do not connect the Unit’s HART leads to an AC powered
HART device while the 4150 / 4150X is on AC power and a serial cable is connected to a PC. Meriam
recommends disconnecting the HART leads from the 4150 / 4150X prior to any communication activity.
