CF Card Replacement:
CAUTION: Due to the large variability of CF cards available on the world market and the
resulting problems with compatibility due to memory layout, signal structuring and power
requirements, REF TEK cannot guarantee a CF card will work in a REFTEK data recorder
unless it is sold through REFTEK itself. REFTEK ensures compatibility through
communications with CF manufacturers and rigorous in-house testing. Some CF
manufacturers refuse to provide adequate information or factory controls to ensure that the
product being sold today is the same as the product sold earlier under the same part
number. CF cards not purchased from REFTEK may work at one temperature but not at
another, or may fail all together.

1130-GPS Overview
This Section explains the REF TEK 130-GPS clock system when it is used with the REF TEK 130
family. The 130-GPS clock system can have either of two receiver boards:
•SiRF µ-Blox receiver module
•Garmin™ receiver module (Orange Ring)(White Ring) and 130-GPS (Integrated Hockey-Puck
design)
A user should be familiar with whatever REF TEK host system is in current use. Documents for
other REF TEK products are available on request.
The REF TEK 130 will report three states for the 130-GPS:
ASLEEP
The 130 has commanded the 130 GPS to go to the Push to fix™ mode.
SEARCH
The 130 system has awakened the 130 GPS and is waiting for it to report that it is locked.
LOCKED
The 130 GPS is locked.
Status of the GPS is shown on the LCD as:
•SLEEP - When GPS is asleep
•SRCH - When the GPS is awake but not locked
•LOCK - GPS is awake and locked
•MinSLL- Minutes since last locked

System Overview
The REF TEK 130-GPS clock which is shown below, is capable of providing both time and position
information, serially, for host systems in the REF TEK 130 Series Data Acquisition System family.
Each 130-GPS is a self-contained unit. The unit is designed around the receiver module. The
receiver board is based on either the Garmin™ unit. The antenna is mounted on the inside top
of the case and the whole unit is situated so that the antenna has clear overhead exposure. A
single interface connector is located at one end of the case. The 130-GPS can be powered by 12
VDC from the host system and supplies the time and position information serially to the host
system together with a 1 Hertz pulse.
