DR128 SysNet
Fitting Instructions
AP3165 issue 4
Fitting Procedure
Step 1
Check which version of PIC you need. The V4 part is
fitted as standard. If you need to run the earlier V2
version then carefully unplug the 28-pin integrated
circuit and replace it with the V2 version supplied.
Make sure its pin 1 is positioned as shown and the pins
are correctly aligned and pressed in.
Step 2
Turn off power to the DR128 and unplug the mains
cable. Remove the 6 fixing screws as shown and lift off
the top cover.
Step 3
Remove the rear panel SysNet option slot blanking
plate by unscrewing the two fixing screws.
Locate and carefully unplug the 26way harness that
connects between the CPU and Lower Connector
circuits.
Step 4
Fit the SysNet card and mounting bracket to the DR128
using the fixing screws attached to the mounting
bracket.
Fold and position the new 26way harness as shown
plugging it into the CPU, Lower Connector and SysNet
cards.
Make sure the harness pins are correctly aligned with
the mating connector pins. Push the plugs fully home.
Check that the harness is neatly folded with the pin 1
red stripe correctly positioned as shown below.
Step 5
Check your work and refit the top cover. Power up the
DR128 and check that it boots up correctly.
Refer to the relevant SysNet Protocol document for
details on programming the remote controller. For
