Remove cover, from central unit.
CAUTION: Before handling the EPROM, discharge any static
electricity from your body by touching a grounded point.

The EPROM could be damaged by static electricity.
1. Refer to the drawing below for correct eprom locations. (Fig.4a)
2. Remove the old system eprom, from the main board. Be careful to pull the eprom out
without bending the legs.
NOTE: Ensure the notch is in the correct direction. Notch on eprom must match the notch on the
socket and markings on the board.
3. Place new eprom in the correct eprom socket as shown. Carefully align the new eprom legs
with the socket and push the eprom into place. Be careful not to bend any of the legs.
PROCEDURE 3. CONSOLE CABLE INSTALLATION IN CENTRAL UNIT
1. Ensure console is properly installed in cab.
2. Route console cable assembly (031-300-060-598) to the central unit following the same path as the
existing console cable assembly. Cut the console cable to the appropriate length.
3. Wire the console cable assembly in central unit referencing the diagram. (Fig. 6)
4. Install the C.U. lid. Reinstall and any grounding wires removed, then install the cover and tighten
screws, making sure the rubber gasket, is positioned correctly, to prevent any moisture from entering the
central unit.

SYSTEM SOFTWARE REPLACEMENT FOR DS350G
1. Remove cover, from central unit.
CAUTION: Before handling the EPROM, discharge any static electricity from your body by touching a
grounded point. The EPROM could be damaged by static electricity.
2. Remove the existing system and CPU eproms from the main board. (Fig. 7) Be careful to pull the
EPROM out, without bending the legs.
3. Install eprom module 024-350-300-172 into the CPU and system software sockets. (Fig. 7a)
Replace the CPU and new system software (MGWT) eprom into the eprom module.
NOTE: The notch on the EPROM and in the socket determines the correct orientation of the EPROM.
Refer to the drawing below for correct EPROM locations.
4. Carefully align the new EPROM legs with the socket and push the EPROM into place. Be careful not
1. Remove existing console cable and strain relief from the central unit and install PG13.5 hole plug
using the existing nut. Remove existing PG11 hole plug. Install new PG11 strain relief using the
existing nut. (Fig. 13)

Cable Assembly Installation (24 350 06 2766 only)
1. Attach inner shield to grounding clamp on the
connection board per diagram. (Fig. 14 and 14a)
2. Install 1/8” and ¼" female terminals on wire
ends and attach to connection board and diode
assy per electrical schematic. (Fig. 15)
3. Reinstall central unit lid and any grounding wires
that were removed.
Grounding of Inner Shield (24 350 06 2766 only)
Inner shield is grounded on connection board.
(Not required when replacing the 050-350-061-189 console). Do not remove
existing cable between console and central unit for installation of the
050-350-061-355 console.

Cut inner shield back to approximately 1.2 inch. Then fold inner shield back to inner jacket, so the inner
shield is 0.6 inches in length.
1. Remove existing console cable and strain relief from the central unit and install PG13.5 hole plug
using the existing nut. Remove existing PG11 hole plug. Install new PG11 strain relief using the
existing nut. (Fig. 13)
