CM4 Four-Point Continuous Monitor

D.1 Overview

This addendum describes the components, installation, cabling, jumper
settings, and set up for the CM4 printer options. An optional printer
can print data for up to nine CM4 monitors. The available printers are
for use in both desktop and rack mount configurations, and operate
in a unidirectional RS-232 communication format. An RS-422 format
is available for a single rack-mounted CM4 monitor communicating
directly to a rack-mounted printer.
The printer serial interface option is factory-installed. Note that all
CM4 monitors require a serial printer interface option to operate any
printer. This addendum can serve as a checklist to ensure the printer
options are correctly installed, cabled, and enabled.
The following is a description of each of the serial printer options
available for the CM4 monitor.
D.1.1 RS-232C
(P/N 1874-0323 and 874021-R or 1874-0324 and 874021-R)
This serial communications interface provides unidirectional RS-232C
communications from the CM4 monitor to a single printer 1847-0323
and 874021-R) or to a share box for multiple printer (1874-0324 and
874021-R). A communications cable is connected to the printer port
located on the rear panel of the CM4 monitor. The RS-232C interface
has a maximum range of 50 feet using high quality shielded cable.
D.1.2 RS-422
(P/N 874023-R)
This serial communications interface provides unidirectional RS-422
communications from one CM4 monitor to an RS-422 printer or
computer. A communications cable is connected to the printer port
located on the rear panel of the CM4 monitor. The RS-422 interface
has a maximum range of two kilometers using high quality shielded
cable.

D.1.3 Desktop Printer
(P/N 874012 110VAC or 1874-0430 230VAC)
The desktop printer has a pre-installed RS-232C adapter for serial
interface. Also included with the option is the adapter cable (25 pin to
9 pin) necessary to connect the printer to the CM4 monitor, and the
printer's Operating and RS-232C Adapter manuals.
NOTE:
Draft mode should be selected to prevent backup of data in
the buffer.
D.1.4 Enclosure Printer Kit
(P/N MVIP2248)
The Enclosure Printer Kit option is designed for customer installation
into a previously purchased Schroff enclosure. The kit includes an
Okidata Model ML 320 Turbo with the serial interface and cable pre-
installed. The kit also includes a paper catcher/storage unit which is
mounted in the rack cabinet directly below the printer.
Switch settings allow the printer to operate with either an RS-232C
or RS-422 interface.
D.1.5 Printer Share Box
A printer share box is required whenever more than one CM4 monitor is
connected to a printer. The printer share box option is available for 120,
and 230 Volts. Table D-1 lists the printer share box part numbers.
The power plug may have to be replaced or a plug adapter may be
required for use in some European countries.
NOTE:
All communications cables needed to connect the CM4 monitors
are included with the printer share box. The printer share box
manufacturer's Owner's and Reference Manuals are included.
