This procedure presumes the operator has basic knowledge of the ROWETECH HASCP and has
experience with serial communication interfaces and test equipment. For further assistance, contact Rowe
Technologies directly.
Connect HASCP communication port(s) to the Windows PC (outlined above). Open the ROWETECH
HASCP software. Select communication port and Baud rate.
Select the Terminal screen on the HASCP software and turn on the power supply to the HASCP and click
Break <CR>.
If you see the Wake Up message on the Terminal screen:

If there is no Wakeup message displayed on the Terminal screen:
•
Verify the Baud rate and Communication port setting.
•
Verify the wiring of the communication port.
•
Verify RS232 communications on the PC by connecting pins 2 and 3 together on the DB9
connector going into the PC. Then send a command for e.g. START to the port. You should see
the command/characters echoed on the Terminal screen.
•
Try a NULL MODEM on the RS232.
•
Connect an Oscilloscope to the RS485 data lines. Then send a command for e.g. START. You
should see the command/characters on the scope display the bit rate should match the PC Baud
rate.
•
Try swapping the 2 data lines on the RS485.
•
Connect an oscilloscope to the ADCP/DVL output data lines on either communication port.
•
Turn OFF the HASCP power. Wait 10 seconds. Turn ON the HASCP power supply:
Measure the voltage at the input to the HASCP pin1 on the power connector. The voltage should be
between 12 and 24 VDC depending on the power supply. If the voltage is out of range find another
supply.
Measure the power supply current. The power up current should be 0.2 to 0.5 Amps if the system is
awake and waiting for a command. If the system is pinging it will be drawing 2 to 3 Amps and 0.2 to 0.3
Amps the rest of the time.
Remove the underwater housing keeping the wiring connectors attached. If there is still an issue contact
ROWETECH with the results of these tests.
