Chapter 1

Description
This chapter describes the DZQ11-SF option and the BA200-series system
enclosure.

1.1 DZQ11-SF Asynchronous Muitiplexer Option
The DZQ11-SF is an option for the BA200-series enclosure ONLY.
The DZQ11-SF asynchronous multiplexer option connects the Q22-bus to as
many as four asynchronous serial data communication lines. It can be used
in many applications, such as data concentration, real-time processing, and
cluster controlling. The DZQ11-SF option module (hereafter refered to as
DZQ11) is dual-height, with a BA200 style bulkhead handle (Figure

The module provides four full-duplex cerial data channels.
conforms to the RS232-C (V.28) and RS423-A (V.10/X.20).

1-1).

The DZQ11

All four channels provide enough modem control to aliow auto answer dial
up operation with modems using full-duplex operations. You can use AT&T

103, 113, and 212 modems,? or the equivalent.
The DZQ11 is program-compatible with the Q-bus DZV11 and with the
UNIBUS option DZ11-A. The only exception is the number of serial lines
supported. The DZQ11 DOES NOT support 20 mA operation.

? The DZQ11 modem control DOES NOT support half-duplex operation of the secondary
transmit-and-receive operation available on some modems (such as the Bell 202).

You can prc:fram each channel separately, selecting one of sixteen baud
rates. Speed tolerance for all rates is better than 0.3%. The 16 possible

1.2 BA200-Series System Enclosures
The BA200 enclosure has a 6- or 12-slot Q-bus backplane and one or two
modular power supplies. FiF“"’ 1-2 shows the 12-siot BA213 and the 6-slot
BA214 enclosure chassis.
The backplane implements the Q22-bus on the
AB rows of each slot. The CD interconnect is implemented in all 12 slots.

MicroVAX systems use the CD rows of slots 1 through 3, and MicroPDP-11
systems use the CD rows oi slots 1 through 4 for their high-speed memory
interconnects.

Figure 1-2:

BA200-Series Enclosures

BA214 ENCLOSURE

BA2VIENCLOSURE

Description

1-3

BA200-series enclosures with mass storage area can hold up to four standard
13.3 cm (5.25 in) devices (three disk drives and one tape drive). Fixed disk
drives face the rear of the enclosure, proviling easy access to the drive
signal and power cables. A TK50 drive faces the front of the enclosure.
The major difference between the BA200-series and other microsystem en-

closures is in the way you connect external devices to the system. Option modules in the BA200-series enclosure connect directly to external 1/O
connectors. Other enclosures require an insert panel and internal cabling
between the option module and the device.

There are two main differences between the modules used in the BA200series enclosure and the modules used in the other microsystem enclosures.
e

Option modules for external devices have bulkhead handles.

These

handles re,)la~e the insert panels and internal cabling found in the BA23

and BA123 enclosures.
¢

Standard Q22-bus modules (such as the RQDX3 and TQK50) have blank
bulkhead covers.

The module handles and blank covers form an electrical seal that complies
with FCC regulations for (1) keeping radio frequency interference generated
by the system in the enclosure, and (2) keeping radio frequencies out of the
enclosure. The inodule handles and blank covers also help to guarantee
proper airflow.

See the MicroVAX Systems Maintenance Guide (EK-001AA-MG) for further
information on the BA200-series (BA213) enclosure.

2.4.2.2 Power Supplies

The BA200-series enclosure contains one or two separate 230-watt power
supplies.

In 12-slot enclosures with one power supply, the power supply is located
to the right of the backplane.

In 12-slot enclosures with two power supplies, the power supply to the
right of the backplane powers slots 1 throuih 6, and the power supply
to the left of the backplane powers slots 7 through 12.

In 6-slot enclosures, the power supply is located to the left of the backplane.

Each power supply in the enclosure must have a minimum 5-amp load on
the 5-volt output to maintain regulation. If a power supply does not meet the
minimum load requirement, you MUST install a load module (M9060-YA)
in an open backplane slot that is powered by the power supply. Otherwise,
the power supply enters an error mode and shuts down the system.
If a power supp'y meets or exceeds the minimum load requrement, you
should remove an existing load module.
Refer to Section 2.7, Relocating Existing Modules, for procedures on installing or removing modules.
