Printer Requirements
Before installing the RS-232C/RS-422 Serial Interface option, you will need to make sure of the follow-
ing two requirements:
• Make sure that your printer has a free network port access slot.
• Make sure that your printer’s “Product Version” is V2.03a or later. If you are unsure of your
printer’s version of code, print a Configuration Summary as described in the user’s guide that came
with your printer. If your printer has an earlier version of code contact your point of purchase.

Safety Precautions
Safety Precautions
CAUTION: Handling ESD-Sensitive Parts
Many electronic parts use parts that are known to be sensitive to electrostatic discharge (ESD). To
prevent damage to ESD-sensitive parts, follow the instructions below in addition to all the usual
precautions, such as turning off power before removing logic boards:
•Keep the ESD-sensitive part in its original shipping container (a special “ESD bag”) until you are
ready to install the part into the machine.
•Make the least-possible movements with your body to prevent an increase of static electricity from
clothing fibers, carpets, and furniture.
•Use an ESD wrist strap on your wrist if available. Connect the wrist band to the system ground
point. This discharges any static electricity in your body to the machine.
•Hold the ESD-sensitive part by its edge connector cover; do not touch its pins. If you are removing
a pluggable module, use the correct tool.
•Do not place the ESD-sensitive part on any metal surface; if you need to put down the ESD-sensi-
tive part for any reason, first put it into its special bag.
•Metal surfaces are electrical grounds. They increase the risk of damage because they make a dis-
charge path from your body through the ESD-sensitive part. (Large metal objects can be discharged
paths without being grounded.)
•Prevent ESD-sensitive parts from being accidentally touched by other personnel.
•Take extra care working with ESD-sensitive parts when cold weather heating is used because low
humidity increases static electricity.
WARNING: To prevent the danger of electric shock, before installing any options be sure to
turn the power switch of the printer to the off [O] position and disconnect the power cord from
the wall outlet.

About this Chapter
This chapter explains the procedure for installing the RS-232C/RS-422 Serial Interface option in OKI
B6100 Printers.
Installing the RS-232C/RS-422 Serial Interface in OKI B6100 Printers
1. Carefully review the safety precautions in the front of this guide before starting this installation
procedure.
2. Ensure that the printer power switch is set to the OFF [ O ] position and unplug the power cord
from the AC outlet.
3. Loosen the thumbscrews at the top and bottom of the left side cover by turning them in a
counter-clockwise direction.

4. Slide the cover towards the rear of the printer and then downwards to remove it.
5. Turning thumbscrews counter-clockwise, remove the blank metal plate covering one of the avail-
able network ports on the controller bracket.
NOTE: It is not necessary to remove the controller from your printer to install the serial interface. For
clarity, the following illustrations depict a controller removed from the printer. When facing the
front of the controller as shown below, network port 1 is on the right and network port 2 is on the
left. However, when installed in the printer, network port 1 is on the bottom and network port 2 is on
top. In the following few steps, a serial network interface is being installed in network port 2.

6. While aligning the front bracket of the serial interface assembly to the two respective thumbscrews
on the controller assembly bracket, firmly seat the 80-pin male connector on the underside of the
interface to the 80-pin female connector on the controller assembly.
7. Secure the serial interface assembly to the controller bracket by tightening the two smaller thumb-
screws in a clockwise direction.

8. Insert the top part of the left side cover into the printer. Ensure the locking tab aligns with the hole
in the printer’s side.
9. Slide the side cover towards the front of the printer to install it.
10. Tighten both thiumbscrews in a clockwise direction.

References for OpenVMS users
You can print to your laser printer via the serial interface option from an OpenVMS system, either
directly connected to the system or through a network device such as a terminal server.
It is recommended that DECprint Supervisor (DCPS) be used for printing. Please see the "Setting Up
Printers" chapter of the DCPS System Manager’s manual for information on creating a DCPS print
queue.
If DCPS will not be used, please see the "Setting Up and Maintaining Queues" chapter of the OpenVMS
System Manager’s manual for information on setting up print queues using the OpenVMS print sym-
biont.
