... Hardware Installation
Q-BUS Systems
A Q-Bus based RT-11 system requires the installation of a
DEQNA or DELQA communications controller. A system memory of at
least 512k is required when installing the Internet Package.
The DEQNA/DELQA EQ22XM.SYS handler requires 36k bytes for code
and packet buffers (the NQXV56.SYS handler requires 14K bytes
for code and packet buffers) and the network server program
TCPIP.SAV will use 64k bytes for a maximum of approximately 100k
bytes before activating any client/server programs. Each active
client/server program will use an additional 64k bytes plus one
or two global PLAS regions each 8k bytes in size.
NOTE
It is possible to install the TCP/IP Package on a 248K
machine using the DEQNA/DELQA 18-bit EQ18XM.SYS
handler. This handler requires 7.5k bytes for code
and packet buffers. This configuration allows at most
one networking application to be active.
Blockmode memory is recommended for use with the DEQNA/DELQA
communications controller although not necessary. The DEQNA or
DELQA interface is connected via a bulkhead cable assembly (with
perhaps an extension ETHERNET transceiver cable) to a tran-
sceiver (with either a thick or thin wire connection).
UNIBUS Systems
A Unibus based RT-11 system requires the installation of a
DEUNA or DELUA communications controller. A system memory of at
least 384k is recommended when installing the Internet Package.
The DEUNA/DELUA 22-bit (Unibus Mapping) NUXV56.SYS handler re-
quires 14k bytes for code and packet buffers and the network
server program TCPIP.SAV will use 64k bytes for a maximum of
approximately 78k bytes before activating any client/server pro-
grams. Each active client/server program will use an additional
64k bytes plus one or two global PLAS regions each 8k bytes in
size.
NOTE
It is possible to install the TCP/IP Package on a 248K
machine using the DEUNA/DELUA 18-bit (Non Unibus Map-
ping) EU18XM.SYS handler. This handler requires 7.5k
bytes for code and packet buffers. This configuration
allows at most one networking application to be ac-
tive.
The DEUNA or DELUA interface is connected via a bulkhead ca-
ble assembly (with perhaps an extension ETHERNET transceiver ca-
ble) to a transceiver (with either a thick or thin wire
connection).
Serial Port Installation If the system is to be configured for remote Telnet login then a pair of dedicated serial lines is required for the ses- sion. The dedicated pair consists of a multi-terminal line cross connected to second multi-terminal line via a NULL-MODEM cable. For a DLV11-J four port serial board the cross connection may be easily obtained by constructing a 4" cable with the 10 wire flat cable flipped between the two ends (1->10, 2->9, .... 10->1). Then cut wires 1,2,9,and 10 at both connectors leaving a 6-wire NULL-MODEM cable. The DLV11-J baud rate should be lim- ited to 4800 as two serial ports are required for the session and is a relatively heavy burden even for a LSI-11/73. Cross connected DZ ports will provide faster and more effi- cient communication.
