Conversion instructions
Model 4102
1. INTRODUCTION
These instructions are intended as an aid to those required to convert a non-configurable model 4102 recorder to the
latest standard, with full user interface. The procedure involves replacing the display module and the PROM on the
SBC board at the rear of the recorder.
Caution
The process involves the handling of circuit boards containing components which are sensitive to static
electrical discharges of voltages as low as 60V. All relevant personnel must be aware of static handling
procedures.
2. CHASSIS REMOVAL
1. Open the door of the recorder, and remove the cassette and pens/printhead as described in the User Guide.
2, Isolate the recorder from line power, then unscrew the jacking bolt (arrowed in figure 1) and carefully slide the
chassis forwards, ensuring that the flexi cable at the rear of the writing system is not forcibly pulled out of its
connector.
3. As shown in figure 2, release the flexi (by pulling the ears of the connector housing upwards) , and remove the
flexi from its connector. Remove the writing system from the case and place the writing system on a static-safe
surface.

5. Turn the recorder upside down, remove the static earthing shim (secured by a plastic rivet) as shown in figure 4,
and gently prise the control board off its mounting pillars as shown in figure 5.
6. Turn the recorder the right way up again and remove all remaining connectors from the control board as shown
in figures 6a/6b.

PROM REPLACEMENT
7. Lay the control board flat on a static safe surface.
8. Note the position of the orientation pip on the existing PROM
(Continuous-trace recorder PROMs are oriented differently
from multi-point PROMS).
9. Use a PLCC extractor tool to remove the existing PROM.
10. Fit the new PROM, ensuring correct orientation (figure 7)
SWITCH ACTUATOR REMOVAL
11. Remove the two metal switch actuators from the chassis
as shown in figure 8.
DISPLAY UNIT REPLACEMENT
12. Cut the tiewrap (A in figure 9) and release the cable form.
13. Remove the hinge pin (B in figure 9) and retain.
14. Fit the new display module, and re-fit the hinge pin.
15. Fit the cable form in it channel, and ensure that the display door can open and close freely, adjusting the cable
form as necessary. Once satisfactory, tie-wrap the display harness and (for continuous-trace recorders only) the
edge detect cables as before.
REASSEMBLY
Note: Figures 10 and 11 show connections for the continuous-trace control board and for the annotator
and chart illumination boards.
16. Remake all the connections between the writing system and the control board, then turn the recorder over and
press-fit the board to the chassis.
17 Re-fit the grounding shim.
18 With the recorder the right way up again, fit the annotator and chart illumination boards (if fitted).
19. Return the chassis to the case, ensuring that the flexi cable to the I/O boards is fitted securely and that it is
locked in place by pressing the 'ears' down towards the body of the connector.
