A special Option 001 deletes the Ethernet cable
stripper and the N-Type Crimp Tool. This option is
recommended when there is more than one installed
network per site.
RJE Interface (UP 27122A)
The RJE interface, used in conjunction with the RJE
software (97077 A or 97087 A) under HP-UX, allows the
HP 9000 Series 500 to emulate an IBM 2780 or 3780
workstation. It permits the Series 500 to be used as a
Remote Job Entry station for batched job communication
with IBM 360/370 (or other compatible) computers using
the IBM Bisync protocol.
The RJE interface features a plug-in card incorporating
microprocessor intelligence that offloads all
communications overhead from the host. This means the
interface card performs all protocol generation and
interpretation, as well as modem control tasks and
pre-processing functions such as character conversion,
blocking and deblocking.
The specific needs of many different RJE applications
are met by selecting programmable configuration
parameters.
Full trace log, communications status and statistics, as
well as hardware self-test, are provided to facilitate
complete monitoring and check-out of the interface.
Features
• 1200 to 19200 baud rates
• Compatible with EIA RS-232C and CCITT V.24
specifications
• Supports Bell type 208B, 2096 and 212 data sets or
equivalent
• Supports Seimens MSV2 protocol
• Works with full or half duplex modems and supports
AUTO ANSWER and ORIGINATE
• Provides link control functions: line bid, normal and
transparent data modes, all responses, and link
termination
• Assures data integrity with CRC error checking
• EBCDIC character recognition
• Space compression/truncation
Operation
The RJE interface works with modems (or modem
eliminators) over switched or non-switched lines. The
maximum data rate supported by the interface is 19.2
Kbps but it also operates at slower rates to accommodate
different modems.
Link control is managed entirely by the on-card
microprocessor. All functions and responses (ACKINAKI
W ACKITTD/RVI) are implemented by the card upon
request by software from the Series 500.
Card parameters and special character handling may
be configured from the HP 9000 Series 500 or allowed to
retain their default values. Configurable parameters
include: record and block sizes, timeouts, retry counts,
conversion tables, record separators and formatting
functions. Special character handling includes: character
code translation, automatic record terminations, adding
and stripping, record and block separator sequences,
blank truncating and padding, and repeated character
compression and expansion.
9
To assist in line quality and link troubleshooting, the
RJE interface card accumulates communication statistics.
A continuous trace log can collect all sent-or-received link
control characters and independently collect all
sent-or-received data characters. You can review the link
control character trace log without having access to the
data character trace log, thus permitting link trouble
shooting without violating data security. A trace log also
collects all internal firmware state changes.
The RJE interface does not recognize horizontal
tabulation and vertical forms control codes. This
capability must be host-resident.

Shared Resource Manager Interface (UP 27123)
The HP 27123 Shared Resource Management (SRM)
Interface allows an HP 9000 Series 500 HP-UX system or
BASIC Language System to interconnect to an HP SRM
system.
The SRM system consists of a dedicated Series 200
controller that manages shared peripherals and a
hierarchical file system on a shared disc connected to it.
BASIC, Pascal, and HP-UX workstations are linked to the
SRM controller via SRM cables and multiplexers. The
benefits of an SRM system are cost savings by sharing
peripheral devices and the convenience of being able to
access common information on a shared disc from
multiple workstations.
HP 9000 Series 500 BASIC Language systems can
perform the same mass storage operations to the SRM
disc that are available with a local disc, except for system
boot. HP-UX systems can copy files from the local HP-UX
disc to the SRM disc and vice versa.
• Cable Specifications
• The HP 272123A Interface is connected to the SRM
system by any of the following SRM cables:
• 97061A - 10 Metres
• 97061B - 25 Metres
• 97061 C - 60 Metres
• 970610 - 60 Metres (unterminated on one end to
facilitate pulling cable thru cable trays.)
Refer to the HP 9000 Data Communications Technical
Supplement (Publication Number 5953-4692) for detailed
configuration and ordering information concerning the
SRM system.
