Specifications

OpenVMS VAX Operating System, Version 5.5-2 SPD 25.01.37
DMR11 Remote point-to-point synchronous interface;
(UNIBUS) replaces DMC11.
DMV11 Point-to-point or multipoint synchronous inter-
face. (Q–bus)
DPV11 Synchronous, 1 line, half or full-duplex point-
to-point communication interface supporting
DDCMP, HDLC, SDLC, or BISYNC protocols.
DSB32 Two line, multiple protocol, synchronous
adapter. (VAXBI)
DSH32 1 line synchronous (full modem control) and 8
line asynchronous (no modem control) com-
munications controller for the Micro/VAX 2000.
DEC423 devices are supported. Maximum
baud rates supported: VMS 19.2 KBPS (kilo-
bits/second). 9.6 KBPS for Micro/VAX 2000,
etc.
DST32 Synchronous single line support for DDCMP
up to 9.6 KBPS, full duplex for Micro/VAX 2000
systems. Concurrent use with the DHT32 is
not supported.
DSV11 Synchronous, 2 line, half or full-duplex point-
to-point communication interface supporting
DDCMP (1 or 2 lines up to 64 KBPS).
DSF32 DEC WANcontroller 620 — Two line syn-
chronous communications controller designed
specifically for the VAXft 3000 processors,
supporting DDCMP. DDCMP is supported at
speeds up to 64 KBPS per line for a two-line
operation.
LAN Options
DEUNA Ethernet to UNIBUS controller.
DELUA
Ethernet to UNIBUS controller. The minimum
revision level required is F1.
DEBNA Ethernet to VAXBI communication controller.
DEBNI Ethernet to VAXBI communication controller.
DEMFA The DEMFA is a high performance network
adapter that connects XMI systems to both
Ethernet and IEEE FDDI (Fiber Distributed
Data Interconnect) local area networks.
DEMNA The DEMNA is a high performance network
adapter that connects XMI systems to both the
Ethernet and IEEE 802.3 local area networks.
DESVA Ethernet controller interface.
DEQNA Ethernet controller to Q–bus. The minimum
revision level required is K3. All systems
utilizing a DEQNA must operate with software
data checking enabled. Since AUTOGEN will
automatically set the correct parameter, no
system management intervention is required.
Not supported by VAXcluster software. Not
supported for any interfaces except for access
using QIO or ALTSTART interfaces.
DELQA Ethernet controller to Q–bus. This is the re-
placement for DEQNA. The minimum revision
level required is C3.
DESQA Ethernet controller to Q–bus for S-BOX config-
urations.
KFE52 DSSI/Ethernet Adapter for the VAXft 3000.
Minimum of two adapters per system providing
redundant connection to the Ethernet and the
DSSI buses.
CI Options
V
AXcluster Software may support multiple CI adapters
per system. Refer to the VAXcluster Software Product
Description (SPD 29.78.xx) for the supported configura-
tions.
CI750 CI Adapter for VAX–11/750 systems. (Mini-
mum microcode version REV 8.7 is required.)
CI780 CI Adapter for VAX–11/780, VAX–11/785,
VAX 8600, and VAX 8650 systems. (Minimum
microcode version REV 8.7 is required.)
CIBCI CI Adapter for VAXBI systems. (Minimum
microcode version REV 8.7 is required.)
CIBCA-AA Native CI Adapter for VAXBI systems. (Mini-
mum microcode version REV 7.5 is required.)
CIBCA-BA Native CI Adapter for VAXBI systems. (Mini-
mum microcode version REV 5.2 is required.)
CIXCD-AA Native CI Adapter for VAX 9xxx XMI systems.
(Minimum microcode version REV 1.0 is
required.)
CIXCD-AB Native CI Adapter for VAX 6xxx XMI systems.
(Minimum microcode version REV 1.0 is
required.)
Miscellaneous
CR11 Card reader. One CR11 card reader is sup-
ported per system. (UNIBUS)
DRV11-WA General purpose DMA interface. (Q–bus)
DR11–W General purpose high-speed DMA interface —
one DR11–W interface supported per UNIBUS.
DR750 High performance general purpose interface
for the VAX–11/750. One DR750 interface is
supported per system. This device may not be
used in conjunction with the CI750.
DR780 High performance general purpose interface
for the VAX–11/780 and VAX–11/785. One
DR780 interface is supported per system. On
the VAX 8600 and VAX 8650 as many as four
per system are permitted provided that the
M8297-YA is used.
DSSI Digital Storage Systems Interconnect.
DWBUA XMI to UNIBUS adapter.
