V
is directly connected to the STOR-X POWER connector (MCBH2M pin 1).
Cycle Wake
is switched
port power from the STOR-X, and is used to wake up the Cycle from sleep so that it may take a sample.
The cable connecting the STOR-X to the Cycle is a straight-through cable (pin 1 to pin 1, pin 2 to pin 2, etc).
Do not confuse this cable with the other STOR-X sensor cables!

Schedule File Requirements
Refer to Section 8 Event Scheduling for a description of the STOR-X schedule file. To control the Cycle PO4,
the schedule file will contain events similar to the following (cycle on port 5):
# Start Cycle sample
00:55:00 POWER +V +5
00:55:05 POWER -5 -V
01:01:00 POWER +V +1 +2
01:02:01 ACQUIRE
60 1 2
01:03:04 POWER -2 -1 -V
01:05:00 POWER +V +3
01:05:11 ACQUIRE
20 3
01:05:34 POWER -3

# Retrieve data from cycle
01:45:00 SAMPLE 5
Here, at 00:55:00, the STOR-X will switch power to the Cycle Wake line for 5 seconds, initiating a sampling
sequence which will roughly coincide with the other sensors that are sampling at 01:02:01 and 01:05:11.
At 01:45:00, the STOR-X is retrieving this sampling data from the Cycle.
Note that the STOR-X extracts time stamp information from the Cycle data
–
it is very important that the
STOR-X and Cycle clocks are synchronized. Please refer to Appendix A
WET Labs Cycle PO4 Configuration.
4.5.2.3
Cycle PO
4
Configuration
The Cycle PO
4
has several operating modes. If not configured properly, it will not operate as expected with
the LOBO/STOR-X system. Please refer to Appendix A
WET Labs Cycle PO4 Configuration.

Sea-Bird SBE 37-SIP
The SBE 37-SIP MicroCAT is a sensor manufactured by Sea-Bird Electronics used to measure conductivity
and temperature in water. The SBE 37-SIP has an integral pump to flush the conductivity cell prior to
measurement. The sensor contains an anti-fouling device to extend deployment time. Integrated pressure
sensors are also available. Example specifications are given below in Table 7; please refer to the
manufacturer’s documentation for complete specifications.
Use caution when testing a LOBO system with an integrated SBE 37-SIP. Running the pump dry will
damage it.
