Power-Up Jumper Check
The MicroTSG’s Printed Circuit Board (PCB) has a jumper that controls how
the MicroTSG wakes up:
•
Autopower (default) – The MicroTSG wakes up when power is applied.
System capability is dependent on the
external wiring configuration:
¾ Three wires – This configuration is useful in simple systems where
a controller applies power, waits for data, and then removes
power
. Only three of the four wires (Power, Ground, and Transmit)
are needed for operation, since it is not necessary to command the
MicroTSG to take samples. Note that the MicroTSG
does not
respond to any commands in this configuration , so initial setup
of the system must be performed with all four wires in place
(see
Command Descriptions in Section 4: Setting Up MicroTSG ).
¾ Four wires – With all four wires (Power, Ground, Receive, and
Transmit), the MicroTSG
can receive and respond to most
commands. Note that the MicroTSG does not respond to QS in
this configuration.
•
Normal – The MicroTSG wakes up when there is a pulse on the serial
interface lines. In this configuration, the MicroTSG can be controlled
using the documented commands and can be commanded into a quiescent
(sleep) state with
QS .
Verify the jumper setting in one of the following ways:
•
Check the Configuration Sheet (in the manual) for the factory setting, or
•
Connect the MicroTSG to the computer as described in Communications
Test and Setup in Section 4: Setting Up MicroTSG . Set the appropriate
communications settings, wake up the MicroTSG with the Connect button
on SEATERM’s Toolbar, and then enter
QS after the
S>
prompt.
The response indicates whether the jumper is in the Normal or
Autopower configuration:
¾ Autopower – system returns
S>
prompt, indicating that the
MicroTSG is not in quiescent (sleep) state.
¾
Normal – system does not return S> prompt, indicating that the
MicroTSG is in quiescent (sleep) state.
Note:
See Appendix II: Electronics
Disassembly/Reassembly for details
on accessing the PCB to change the
jumper setting.
Note:
For a three-wire external wiring
configuration, or to use the MicroTSG
with the Interface Box, set:
•
J1 jumper to Autopower
•
AutoRun=Y , and
•
SingleSample=N
See Section 4: Setting Up MicroTSG .
