2-12. POWER CABLE. The counter is equipped with
a detachable 3-wire power cable. Proceed as follows
for installation.
a. Connect plug (3-socket connector) to ac line
jack at rear of instrument.
b. Connect plug (2-blade with round grounding
pin) to 3-wire (grounded) power outlet. Exposed
portions of instrument are grounded through the
round pin on the plug for safety; when only 2-blade
outlet is available, use connector adapter (HP Part
No. 1251-0048), then connect short wire from side of
adapter to ground.
2-13. REMOTE PROGRAMMING, OPTION 002
2-14. The following paragraphs describe remote pro¬
gramming requirements for the counter with Option
002. See Paragraph 2-33 for Option 004 programming.
2-15. Front Panel Controls
2-16. The following front-panel controls are program¬
mable:
a. FUNCTION
b. TIME BASE/MULTIPLIER
c. CHECK function
d. SLOPE
e. SAMPLE RATE and HOLD
f. LEVEL controls
g. INPUT C switch (5327A only)
h. RESET
2-17. The following front-panel controls are NOT
programmable:
a. AC/DC
b. SEP-COM
c. FAST/NORM
d. ATTEN
2-18. The trigger level controls may be remotely pro¬
grammed or the front-panel LEVEL controls may be
used. It is possible to program the LEVEL controls
without programming the remainder of the front-
panel controls. When remote programming is used,
the LEVEL controls must be set to PRESET. Display
time may be remotely programmed and/or the front-
panel controls may be used.
2-19. Remote Programming Requirements
2-20. All lines may be controlled by TTL or DTL
signals or contact closure to ground when the unit is
being remotely programmed: except the trigger levels
which are programmed by an analog level (if pro¬
grammed) and the display time line (Hold), J10 pin
35, which should NOT be pulled up to +5 V by less
than 200Q while programming.
2-21. When the unit is NOT being programmed (Ext
line high), all the lines should be left open or pulled up
to +5 V by not less than 5kO, except the trigger levels,
which should be open circuited.
2-22. Remote Programming Procedure
2-23. In order to remotely program the counter, the
following must be done:
a. Set FUNCTION switch to any function but
START or STOP.
b. Ground the EXT line at rear-panel REMOTE
PROGRAM connector J 10(17). This disables the
front panel switches. Ground is available at J 10(36).
c. Select the desired function.
d. Select the desired time base.
e. Select the slope ( + or -) for CHANNEL A and
B. This is accomplished by grounding the Slope line
for (-) and leaving it open for (+). Slope A line is
J10(28). Slope B line is J 10(29).
f. Select the trigger level for input signal.
g. Adjust the display time.
h. Manual reset is available by grounding (<.7 V)
pin 34. Check is available by grounding pin 14.
