UDM 35/40 PANEL METER USER MANUAL
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 powerup.
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 first sub-parameter in this group. Each successive will scroll through the
remaining sub-parameters. To change a setting, press the
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.
