TR-2100 User Manual
RECOMMENDED TOOLS AND EQUIPMENT LIST:
• Computer with one unused RS-232 port
• AMETEK TR-2100 direct connect cable
• DVM / Digital Volt Meter for DC
• Basic technician hand tools, Phillips screwdriver, 5/16
• ESD protection equipment
• Several very small flat blade screwdrivers (one with a long length)
TR-2100 UNITS CONTAIN STATIC SENSITIVE ELECTRONIC DEVICES.
PROPER ELECTROSTATIC DISCHARGE (ESD) DAMAGE PREVENTION AND
HANDLING TECHNIQUES SHOULD BE FOLLOWED.
Adjustment Procedure:
1. To open the front panel of the TR-2100 unit, use the two screws at the top.
Locate the white connector on the CPU card, see Figure 9, this is where you will
monitor your 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. Attach a digital volt meter's positive
connector to Pin #12 (located on the far left of the connector). Count five pins
over to the right (including pin #12) and attach the meter's negative probe to pin
#8. Set the DVM for Volts DC. If the voltage is already between 4.91 to 5.1
VDC, you can stop here and close the front panel. If the voltage is not between
these specifications, then you must continue with this procedure.
2. Hook up your computer to the front RS232 port of the TR-2100 and set up
communications to the unit using DS32 software. After you have established
communications, make sure you know the current configuration of the TR-2100.
Also, make sure that you have downloaded any events that you may want to
save. This is not required, but is done just as a safety precaution. Now
disconnect DS32 communications from the TR-2100 and remove the
communications cable from the front port of the unit.
3. Setup your ESD protection. Open the front panel and turn the internal power
switch to off. We also recommend removing the power source to the unit. You
should not need to disconnect the power wiring at the rear of the TR-2100. Open
the fuse or breaker that supplies power to the rear of the chassis, as these cables
may be exposed to the chassis in the operation. Next, you need to remove any
cables (except the input Power wiring) on the back of the CPU chassis. This may
include the IRIG-B/GPS, Network, Printer, Phone and RS-232 cables, see
4. Locate the two brackets located inside the TR-2100 on either side of the chassis,
see Figure 9. Each bracket is held in position by one screw, located either in the
top or centre of the white bracket. Remove the screw holding each bracket and
remove both brackets that hold the chassis.
CAUTION:
