EMETER II, Data Loggers, and Accessories

EMETER II SET with RDU (#HP-EM2-SET)

• Emeter II
• RDU (remote data unit)
• Emeter II<>RDU Data Cable
• Emeter II Power Input Plug

The Emeter II supports the RDU by downloading log files to Emeter, Display of log files, Calculation of Thrust-Efficiency (if prop selected), Calculation of internal resistances... and much more.  In addition, it can program Hyperion TITAN ESC, ATLAS Digital Servos, upcoming ATLAS ESC.  It can drive servos or ESC via the dial on the face, or create automated test routines.  We could go on... but just have a look at the Quick Guide link below!
(note: HP-EM2-SET saves $20 over purchase of separate Emeter & RDU)

EMETER II & CABLES (#HP-EM2)

• Emeter II
• Emeter II<>RDU Data Cable
• Emeter II Power Input Plug

RDU UNIT - REMOTE DATA UNIT (#HP-EM2-RDU, see also #HP-TI-PRGUSB below)

• Logs remotely, or at bench while connected to Emeter or PC via USB Adapter (TI-PRGUSB)
• Records internally:  Ambient Temp, Height, Throttle, Current, Voltage, Watts
• Option External Sensors:  Temp1, 2, and 3.  Reliable Phase Tachometer for Brushless Motors.
• Can be connected to Emeter Suite Software for DL to display of Data on PC, or Configuration
• Sample rates from 4 samples per second to 8 seconds per sample
• Firmware upgradable by Emeter with SD card installed, or by PC application

LDU UNIT - LOCAL DATA UNIT (#HP-EM2-LDU, see also #HP-TI-PRGUSB below)

• Logs at bench while connected to Emeter or PC via USB Adapter (TI-PRGUSB)
• Records to Emeter/PC: Current, Voltage, Watts
• Option External Sensors: Temp1, 2, and 3. Reliable Phase Tachometer for Brushless Motors.
• Sample rates from 4 samples per second to 8 seconds per sample
• Firmware upgradable by Emeter with SD card installed, or by PC application
  (logging with LDU direct to PC requires Emeter II Suite installation. See top of this page)

OPTION TEMP UNIT 1 (#HP-EM2-TMP1)

This unit connects directly to the RDU (LDU) "Aux" port. Temps #2 and #3 then daisy-chain to Temp
#1. Therefore purchase this one first, then temps 2&3 if desired.

Generous 25cm (10") cable length means a good reach even in larger models...

OPTION TEMP UNITS 2 & 3 (#HP-EM2-TMP23)

The Temp#2 unit connects directly to Temp#1 unit, so Temp#1 is required to use these. Temp#3 connects to Temp#2. Temps 2 and 3 have cable length of 20cm each, so max reach of Temp#3 unit from RDU is about 65cm (~26").

OPTION PHASE TACHOMETER for brushless motors (#HP-EM2-TACHBL)

This one is a beauty! Just attach inline on one of the three brushless motor wires (solder up a male/female connector adapter for convenience) and log motor rpm extremely accurately throughout the motor run. You need to know how many magnets are in your motor to configure the RDU, but even if you don't know the Emeter can be connected and RDU (LDU) rpm compared with the Emeter tach. Makes it a snap to set it up right, every time... And this unit is NOT plagued by the problems found in some other brands. It's rock solid!

Special Y-Cable for RDU<>Rx THROTTLE Channel (HP-EM2-YCBLTHR)

For Logging throttle position and/or Control of ESC. (for RDU only)

EMETER<>RDU (or LDU) DATA CABLE (#HP-EM2-4PINCBL)

This data cable comes with the Emeter itself. As such, it is mainly for replacement or as a spare. Note that it is also used to program Hyperion TITAN ESC via the Emeter II.

EMETER POWER INPUT CABLE (#HP-EM2-PWRCBL)

This power input cable comes with the Emeter itself. As such, it is mainly for replacement or as a spare.

TITAN USB<>SERIAL ADAPTER (#HP-TI-PRGUSB)

This adapter is only necessary if you've purchased RDU or LDU alone (i.e. you do NOT have EmeterII) You'll need it to connect your RDU to the Windows PC Emeter II Suite Software. The software allows you to configure the RDU via PC, Download, Store, and Display Log File results, and Bench Test live and direct to PC.

SEE THIS PAGE for information on drivers and setup for the TI-PRGUSB adapter.

Note: TI-PRGUSB comes with an adapter marked "Emeter". It is for Emeter v1 and NOT used with RDU or EmeterII.

Other Items Suggested

• A standard SD Memory Card for the Emeter II. Anything from 64MB to 4GB will work. Some dealers will be offering 2GB cards with the most recent firmware, help files, and prop constants installed for about $12, we expect. You may use mini or micro SD cards in a standard adapter.
• A PC Card Reader for SD Card. The Emeter<>PC interface is via the SD card. Most laptops and many printers include card readers...
• High Quality gold-plated connectors between your batteries, RDU, and motor controllers. Very important!
