UDM Description
The UDM 35/40 series is a universal Digital Panel Meter that has been
developed to meet the most advanced application requirements. The UDM 35
offers:
• Quick assembly and maintenance using plug & play modules
• Quick & easy parameter programming and parameter cloning to
other UDMs by means of UDMSoft or PC HyperTerminal
• Powerful variable control by means of up to four (4) alarm outputs
• Alarms can be up-down functions with automatic reset, up-down
with manual reset, and down alarm with disable function at power-
up.
The UDM 40 offers the same features as the UDM 35, with the following
additional benefits:
• Display color adaptable to Green, Red and Amber
• Management of non-linear signals using the available 16-point
linearization capability
• “Alarm status at a glance” using a sequence of display colors that
can be programmed by the user

UDM 35/40 Programming Fundamentals
There are no jumpers to consider when programming the UDM 35/40. The
programming mode allows the user to define all of the instrument’s parameters.
Shown below are a description and the UDMxx display symbol for each basic
parameter grouping:
• Password for access to programming
• Input Probe Selection / Signal Range (current, voltage,
temperature, resistance)
• Cold Junction Compensation
• Display Selection (diSP)
• Display Color (CoLr)
• Scaling of Input Value
• Input Signal Linearization
• Alarm Set-Point (SP1 – SP4)
• Digital Filtering
• Analog Output Scaling
• Serial Port Configuration
• External Command from Input Contact

Access to Programming Mode
Press and hold for 2 seconds. Display will indicate (password).
Within 2 seconds, four zeros “0000” will be displayed as follow:
This is your prompt to enter your password. Each individual digit is selected from
left to right by toggling the key. Changing the value of each digit is
accomplished using the and arrows. When completed, press to
confirm this step. If the password you entered is not correct, you will not be
allowed access to program. Factory default password is set to “0000”.
Note: Choice of a password value is significant. Values from “0000” to “4999”
protect direct access to both set points and all other parameters. A password
value from “5000” to “9000” allow direct access to alarm set points only.
Negotiating the Programming Menu
After password is verified, you are in the Programming Mode. After
approximately 20 seconds, the unit will revert to RUN mode if no further entry is
made. Movement across the flow chart (see product carton instruction sheet for
BD35 and BD40) to a specific parameter heading is accomplished using the
and arrow keys. Pressing the UP key tabs from left-to-right across the flow
chart. Pressing the key tabs from right-to-left. Upon reaching the desired
parameter to configure, press . The display will indicate the current setting for
the first sub-parameter in this group. Each successive will scroll through the
remaining sub-parameters. To change a setting, press the or keys when a
value of a sub-parameter is displayed, followed by to confirm the change and
advance to the next sub-parameter.

Programming the Input Modules
Press and hold for 2 seconds. Display will indicate PASS (password). Within
2 seconds, four zeros “0000” will be displayed. This is your prompt to enter your
password. If zero “0000” is your password, simply press to confirm. You
have approximately 20 seconds to begin programming before the unit reverts
back to run mode. (To enter a unique password, see Access to Programming
Mode, above.)
Input Selection
Press the key once to advance to Input
When the TRX module is installed, you must first indicate probe choice:
TRX input modules offer three Probe (Prob) choices: thermocouple* (tc),
RTD (rtd), plus resistive (rES). Use or keys to make selection.
Press . Use keys to select Range (r1, r2, r3, r4, r5, r6) according
to table below and on instruction sheet. Press .

LSX and HSX input modules offer True RMS (trnS) or DC measurement
(dC). Use keys to make selection. Press .
Press keys to select Input signal integration time value (intt).
If all zeros “0000” is selected, “Auto” will be displayed and the value will be
automatically calculated from 100ms – 999.9 ms. Press to confirm.
Press to advance to next program step sequence.
Cold Junction Compensation (CJC) Temperature Compensation
Available only when TRX input module is installed.
TRX module with Thermocouple (tC) requires configuration of Cold
Junction Compensation (CJC). Press key to advance to CJC Then
to enter.

Press key to select Auto (Auto). Press to confirm. . Press to
advance to next program step sequence.
Manual compensation should only be used in special applications. Consult
factory.
Configuring the Display (diSP) UDM35 only
UDM 35 (BD35) base unit displays may be configured as 3 ½ digit (1999)
or 3 digit + dummy zero (9990). When “diSP” is displayed, press .
Then press keys to make selection. Press to confirm. Press
to advance to next program step sequence.
Selection of Display Color (CoLr) UDM40 only
UDM40 (BD40) base unit offers three display colors. When “CoLr” is
visible on the display, press .
Use keys to select RED (rEd), Orange (orAn) or Green (GrEn).
Press to confirm. Press to advance to next program step sequence.

Scaling the Inputs
When is displayed, access is available for configuring the
electrical input range, the decimal point position and display span as
follows:
Electrical Input Range (HiE and LoE)
Allows the operator to define an electrical input range different from the
standard range setup at the “inP” programming step. As example, a UDM
with a full-scale 20mA (19.99mA) setting, it is possible to select an
electrical input range from 4.00mA (Lo.E) to 19.99mA (Hi.E) by
proceeding as follows:
When is displayed, press . “LoE” will appear.
Using the key, toggle to select a digit, then press the or key to
choose the desired value. Using the key, repeat as necessary until all
digits have proper values. Press .
“HiE” will now appear.
Using the same procedure as above, toggle through the digits using the
key and choose the desired values with the or key. Press to
confirm and advance to the next parameter, Decimal Point Position.

Decimal Point Position (dP)
The decimal point position is relative to the Display Value, which will be
discussed next.
When “dP” is displayed, press . Using the and keys, select the
decimal point position and press to confirm and advance to next step,
“Lod” and “Hid”, the display span parameters.
Display Span (Lod and Hid)
Allows the user to define the actual display span (in engineering units)
corresponding to the previously defined electrical input range (HiE and
LoE). The “Lod” value represents the minimum displayed value; “Hid”
represents the maximum displayed value.
When “Lod” appears, press key to toggle to proper digit. Use the
and keys to select desired value. Repeat procedure until all digits
have been set, press to confirm and advance to the next step, “Hid”.
Repeat the same procedure to select and confirm the “Hid” values. Press
to confirm. Press to advance to the next program step sequence.
