The RS-232/PS2 Module provides communication ports 3 and 4. If the PS2 connection is used, it will
automatically be assigned communication port 4 and the DB 9 of communication port 4 will not be
recognized. An option-mounting bracket (24675B-300A0) is required to install this option.

Installation Instructions
1. DISCONNECT POWER! UNPLUG THE MODEL 675 TO INSURE DAMAGE WILL NOT OCCUR
DURING OPTION INSTALLATION.
2. Remove the (6) 38-31-8710 M5 x 0.8 x 10 mm screws from the enclosure bottom plate and set it aside.
Be sure to install the SBM modules first on the option-mounting plate.
3. Locate the (6) holes to the left of the space labeled as ETH on the option-mounting bracket. The holes
being used are the (2) inside holes.
4. The nylon spacers have a short end and long end. Install the short end of the (2) nylon spacers through
the holes of the option-mounting bracket. Make sure the spacer is snapped in tightly.
5. Position the RS-232/PS2 Module so that the DB9 connectors and PS2 connector face the same edge as
the notch. Install the RS-232/PS2 Module on the (2) spacers. Refer to Figure 2-8 for illustration. The
board will not be supported in the front until it is installed to the rear panel
6. Cut out the rear label to match the installed options. For the RS-232/PS2 Module cut out the dotted line
label COM 3, COM 4 and PS2. Refer to the back panel on page 10.
7. Remove the (4) screws from the DB 9 connectors on the RS-232/PS2 board and set them aside.

through the holes for COM 3 and COM 4. Tighten the option bracket down with the (2) 38-31-8710 self-
tapping screws included with the option mounting bracket kit. Refer to page 2-6 for option bracket install
instructions.
9. If the RS-232/PS2 and Ethernet Module option are both installed, connect the 9" ribbon cable from J5 of
the Ethernet Module to J4 of the RS-232/PS2 Module. Then connect the 9" ribbon cable which came
with the RS-232/PS2 Module from J2 of the RS-232/PS2 Module to J18 of the main board. Refer to
Figure 2-7 for illustration.
10. If the RS-232/PS2 Module is the only communication option being installed, connect the 9" ribbon cable
from J2 of the RS-232/PS2 Module to J18 of the main board.
11. Reinstall the enclosure bottom plate.
Do not connect the Ethernet Module or RS-232 Module cables to the J4 BDM connector on
the main board. This connection will cause damage to the main board making the Model 675
inoperable.
