5.
The ground braid that supports the Front Panel will need to be removed; one nut
holds this inside on the left panel. Locate the two ribbon cables that go between
the ACQ card and the Inputs Cards located above it. You will see a large and
smaller ribbon cable that connects to all of the input cards. Remove these two
cables from the ACQ card end. See Figure 9 for the cables.
6.
Slide the CPU chassis out; the correct distance can be seen in Figure 10. Make
sure that someone supports it as needed so it does not fall. Now check to make
sure that the input Power wires on the back are not touching the chassis,
this is
very important.
7.
If it is electrically safe, apply power back to the chassis INPUT Power
connections. Turn on the internal switch (the small switch inside of the TR-2100
unit). The unit will start its normal boot up sequence once you turn the switch on.
8.
Locate the White connector on the CPU card (see Figure 9). This is where you
will monitor five volts DC. This white connector is located just to the right of
the ribbon cable that goes to the hard-drive on the CPU board. Note the arrow in
the middle of Figure 9 pointing to it. Set the Digital Volt Meter for Volts DC.
Attach the meter’s positive probe to Pin #12 (located on the far left of the
connector). Count five pins over to the left (including pin #12) and attach the
meter’s negative probe.
9.
Using a long, small, flat blade screwdriver, locate the Blue potentiometer on the
Power supply. See
Figure 11 for the location. Adjust this
potentiometer until the DVM reads 5.00 VDC, +/- 0.05 VDC.
10.
Next, turn off the internal power switch and also turn off the power to the rear
power connector. Remove the DVM from the white connector.
11. Reverse the order of the above procedures to reconnect all of the cables and close
the front panel on the TR-2100 unit.
12. To verify proper operation, set up a direct connection using DS32 to the TR-
2100. When connecting to the recorder, the program may prompt you to update
the computer’s/recorder’s local configuration. Select to update the remote
recorder’s configuration. If possible, have the computer (running DS32/DSA32)
call into the TR-2100 by modem, to verify that the TR-2100’s modem has been
initialized correctly.
13. Make sure that the unit still has the correct parameters, and will trigger and
record a waveform on all channels that have voltage or current going into them.
