900 MHz RF USB Modem 
Instruction Sheet 
Introduction 
The 2635A-RF900USB 900 MHz RF USB Modem 
(referred to as “the Modem”) is a radio-frequency 
transceiver that, used together with the 2635A-RF900 
Serial RS-232 Modem, creates a wireless link 
between Fluke Hydra Series Data Loggers and a 
computer (PC) running Hydra application software.  
Note 
The modem operates in the 900 MHz 
frequency range and is approved by the FCC 
for use in the United States. Operation in 
other countries may violate local regulations. 
When operating outside the United States, 
check with the appropriate governing agency 
in the host country prior to Modem operation.  
This instruction sheet assumes familiarity with the 
Hydra software and Hydra Series Data Logger 
operation. If unfamiliar with Hydra software or the 
Hydra Series hardware, refer to the software user’s 
documentation or the appropriate Hydra Series Users 
manual. The Modem is shown in Figure 1.

sheet)  
  Quick Start Guide

Requirements  
The Modem requires a PC with one free USB port 
and Windows XP, 2000, or 98 SE.  
Installation  
Each wireless system requires two modems – one 
base station connected to a PC, and one remote station 
connected to a Hydra Data Logger. This USB Modem 
is used as a base station connected to the PC; the 
remote station connected to the Hydra is a 2635A-
RF900 Serial RS-232 Modem.  
To ease system setup, the Modem’s factory default 
settings are correct for proper PC-to-Hydra operation 
without further adjustments. There are no setup 
differences between the base and remote stations.
