▼ To Install the Adapter
Caution – Electronic components on printed circuit boards are extremely sensitive
to static electricity. Ordinary amounts of static electricity generated by your clothing
or work environment can damage the electronic equipment. When installing the
SunHSI/U adapter in a system, use anti-static grounding straps and antistatic mats
to help prevent damage due to electrostatic discharge.
5
Note – Refer to your system installation guide or service manual for detailed
instructions for the following steps.
1. Power off your system, using the standard shutdown procedures described in
the Solaris Handbook for Sun Peripherals or your system service manual.
The Solaris Handbook for Sun Peripherals is shipped with the Solaris OS software
and is available on the http://docs.sun.com web site.
2. Remove the cover from the unit to access the card slots and connectors.
3. Select an available 3.3 Volt or 5 Volt PCI slot and remove the slot filler panel.
4. Insert the adapter into the PCI connector of the system unit.
Ensure that the front plate on the adapter mounts flush with the chassis panel
opening.
5. Install the front plate screw to secure the adapter into the chassis.
This also provides a chassis ground connection to the adapter.
6. Reinstall the cover on the unit.
7. Attach the serial port cable assembly to the I/O connector on the adapter.
8. Connect any cables from the peripheral devices to the RS-449 connectors on the
adapter’s cable.
9. Turn power back on and allow the system to reboot.
This completes the hardware installation. Proceed to “SunHSI PCI Software
Installation” on page 9.
External Cabling
The SunHSI/U adapter provides external connectivity through a passive cabling
system. A hydra-style connector provides connectivity to four RS-449 devices by
means of four DB-37 female connectors in a DTE configuration.
Note – Always use shielded twisted pair RS-449 cables with your SunHSI/U
adapter.
6 Sun PCI High Speed Quad Port Serial Interface Adapter User’s Guide • May 2010
RS-232 to RS-449 Connections
In order to connect RS-232 devices to the adapter, you need to install an externally
powered RS-449 to RS-232 interface converter to each DB-37 connector on which you
intend to connect an RS-232 device. A converter is necessary because of
incompatibilities between RS-232 and RS-449 signal levels.
To obtain an externally powered RS-232 to RS-449 interface converter, contact:
Black Box Corporation at: http://www.blackbox.com
Note – Use only externally powered RS-449 devices with the SunHSI/U adapter.

SunHSI Utilities
The SunHSI software includes the hsip_init, hsip_loop, and hsip_stat
utilities. This chapter contains a short description of each utility. Refer to each man
page to get more information on the commands. Also see “Viewing the Man Pages”
on page 41.
This chapter includes the following topics:
■ “hsip_init Utility” on page 17
■ “hsip_loop Utility” on page 20
■ “hsip_stat Utility” on page 21
Note – You need to be superuser (root) in order to run the hsip_init,
hsip_loop,orhsip_stat utilities.
hsip_init Utility
The hsip_init utility enables you to modify some of the hardware operating
modes common to synchronous serial lines. This modification is needed for the
operation of some communications packages and is useful in troubleshooting a link.
See the hsip_init(1M) man page for details.
The hsip_init utility includes options for T1 compatibility and operating modes. See
“T1 Compatibility Options” on page 18 and “Operating Modes Options” on page 18
for information on these options.
17
T1 Compatibility Options
The version of the hsip_init utility shipped with the SunHSI software has options
that enable you to invert data and clock signals to accommodate the requirements of
T1 or CEPT transmission equipment. The hsip_init parameters that allow for
inversion are:
■ txd – transmit data signal
■ rxd – receive data signal
■ txc – transmit clock signal
■ rxc – receive clock signal
The effect of the default settings for all of these parameters is that SunHSI software
does not invert the data or clock signal controlled by the parameter. To invert a
signal, you specify a setting of the form param-name=-paramname, for example,
txc=-txc.
As an example, suppose you want to invert the transmit and receive data signals on
the first SunHSI/U port (port 0) on the second SunHSI/U adapter in your system. To
do so, enter the following command:
# hsip_init hihp4 txd=-txd rxd=-rxd
To invert both clock and data signals, enter:
# hsip_init hihp4 txd=-txd rxd=-rxd txc=-txc rxc=-rxc
Appendix C discusses the background and requirements for these inverted settings.
Operating Modes Options
This section describes the operating modes that you can set with the hsip_init
utility.
The SunHSI software operates in two main operating modes, the high-level data link
control (HDLC) mode and the IBM (SDLC) mode. The HDLC mode always operates
in a full-duplex, point-to-point fashion. While the IBM mode defaults to a
full-duplex, point-to-point, operation.
18 Sun PCI High Speed Quad Port Serial Interface Adapter User’s Guide • May 2010
HDLC Mode
The default operating mode used by the SunHSI software is the HDLC full-duplex
protocol (mode=fdx). In this mode the transmitter is always enabled. The
transmitter sends flag bytes continuously when it is not sending a data frame.
If no message is currently being transmitted, the driver will attempt to start sending
its next message. At this point the driver indicates that it is busy transmitting, to
prevent the transmission of another message concurrently. The driver also activates
a mechanism that ensures that the transmit operation will not hang if the hardware
is not responding.
When the transmission is completed, the busy mechanism previously set is cleared
and the next message can be transmitted. If the transmission is hung an abort
sequence is sent instead of the cyclic redundancy check (CRC), so that the receiver
will not interpret the frame as valid data. The message is discarded, and the output
error statistic is incremented, which allows for a proper recovery by higher level
protocols.
The received data is buffered until a complete frame has been received. If any error
occurs during the reception of a frame, the appropriate statistic is incremented and
the frame is discarded.
IBM (SDLC) Mode
SDLC mode is designed to support IBM system network architecture (SNA)
communications. It uses most of the same protocols used in HDLC mode, with two
major exceptions:
■ When the line is idle, instead of sending flag bytes the transmitter is disabled.
■ The request-to-send (RTS) and clear-to-send (CTS) signals are used to gate
transmission.
IBM Full-Duplex Mode
When the SunHSI software is set to this mode (mode=ibm-fdx), the software uses a
full-duplex point-to-point communication protocol. Both ends of the link are
expected to have RTS and CTS signals asserted at all times when data is being
exchanged. When starting a message transmission, the interface raises the RTS signal
and expects the CTS signal to be asserted immediately. If this is not done, all
messages currently queued for transmission are discarded, and the write operation
returns an error.
Chapter 4 SunHSI Utilities 19
If the CTS signal drops before the frame transmission is complete, the frame is
discarded and the abort error statistic is incremented. If the transmission underruns,
an abort sequence is not sent and the frame is silently discarded. The RTS signal
remains asserted until the data transmission is complete.
IBM Half-Duplex Mode
Half-duplex is a submode of the IBM mode (mode=ibm-hdx). Half-duplex mode
operates in the same manner as full-duplex mode except that transmission cannot
occur while receiving, and vice-versa. When a transmission is completed, the RTS
signal is dropped. Dropping the RTS signal tells the remote station to begin
transmitting if it is ready to.
IBM MultiPoint Mode
In a multipoint configuration (mode=ibm-mpt), more than two stations share a link.
This configuration is accomplished by designating one station as a primary station
and the rest as secondary stations. In this mode, the port acts as a secondary station.
The primary station arbitrates traffic on the link by polling the secondary stations, to
see if they are ready to transmit.
If a secondary station has data to transmit, it will raise its RTS signal and check for
CTS signals. When a CTS signal comes up the station may begin transmitting,
following the same rules for RTS and CTS signals used in half-duplex mode. When
the transmission is complete the secondary drops the RTS signal, which enables
another station to respond to a poll and begin transmitting. The RTS signal cannot be
dropped until the transmission is complete.
hsip_loop Utility
The hsip_loop utility is high-speed, synchronous, serial loopback test program for
high-speed serial interface. The utility performs several loopback tests that exercise
the components of a serial communications link. See the hsip_loop(1M) man page
for more information.
20 Sun PCI High Speed Quad Port Serial Interface Adapter User’s Guide • May 2010
hsip_stat Utility
The hsip_stat utility reports the event statistics maintained by the SunHSI device
driver. The report might be a single snapshot of the accumulated totals, or a series of
samples showing incremental changes. At the beginning of the report, the device
name being used to query a particular device appears. See the hsip_stat(1M) man
page for more information.

Null Modem Cable Requirements
A synchronous null modem cable is a specially-configured cable that simulates
modems that are connected back-to-back. When the distance between the two host
systems is not great, you may be able to use a null modem cable instead of a
synchronous modem or a synchronous modem eliminator.
The maximum distance a null modem cable can work is determined by the
specification for your serial port interface.
There are two steps you must perform to use a null modem cable for machine
supplied clocking:
Run hsip_init (see “Configuring Internal or External Clocking” on page 30) so that
the Sun system, in the absence of a synchronous modem, supplies clocking on the
serial line.
Build or configure the cable for the null modem.
Note – You must run hsip_init each time you reboot your system.
The following topics are included in this appendix:
■ “Configuring Internal or External Clocking” on page 30
■ “Building the Null Modem Cable” on page 30
29
Configuring Internal or External Clocking
To configure an RS-449 port to provide transmit clocking for itself as well as receive
clocking for the other end of the link, set the txc (transmit clock) and rxc (receive
clock) parameters in hsip_init to baud and rxc, respectively. For example, the
following hsip_init command sets the data rate of the first Sun HSI serial port to
9600 bps and sets the clocking as just described:
# hsip_init hihp0 9600 txc=baud rxc=rxc
You enter such a command at both ends of a link if both sides are supplying clocking.
In the situation in which you have Sun systems at both ends of a link and have one
system supplying clocking for both sides, on the system that is not supplying the
clocking, you enter:
# hsip_init hihp0 9600 txc=txc rxc=rxc
Building the Null Modem Cable
To build a null modem cable, you can configure your own cable or use a standard
cable with an adapter box.
Note – Be sure to use shielded, twisted pair wire when building a null modem cable.
If you decide to use an adapter box, be sure to obtain an adapter that allows you to
change the pin configurations. Pre-configured adapters generally do not work with
synchronous protocols because they do not handle clock signals correctly.

FIGURE B-1 illustrates a synchronous null modem cable that allows you to connect
two Sun systems that each supply clocking, using the RS-449 interface. Each Sun
supplies clocking on pins 17 and 35. The null modem cable routes this clocking to
pins 8 and 26 on the opposite side to provide receive clocking.
Because the RS-449 interface is balanced, there are two pins for each signal. For
example, Transmit Data (TxD), pins 4 and 22, is connected to Received Data (RxD),
pins 6 and 24. This means that pin 4 is connected to pin 6 and pin 22 is connected to
pin 24.

T1 Inverted Data and Clock Signals
This appendix includes the following topics:
■ “Data Signal Inversion” on page 35
■ “Clock Signal Inversion” on page 37
Data Signal Inversion
The requirement for inverting data signals arises from the “ones density” problem
you encounter with most T1 transmission lines in North America. The T1
transmission scheme uses a signaling mechanism known as Alternate Mark Inversion
(AMI), in which one bits are represented by a positive or negative pulse, while zero
bits are represented by the absence of a pulse. In this scheme, the polarity of each
pulse must be the opposite of the polarity of the pulse which immediately preceded
it. This signaling scheme makes it possible to embed a reference clock for the data
into the data stream itself.
Various types of T1 transmission equipment, such as Data Service Units (DSU),
Channel Service Units (CSU), repeaters, and various telephone central office
equipment, must be able to keep a phase locked loop (PLL) circuit locked on to this
reference clock. This PLL circuit uses the pulses generated when one bits are
transmitted to lock the embedded clock to a local reference oscillator. To keep the
PLL circuit locked on the extracted clock, a certain density of pulses (one bits) must
be guaranteed. For North American T1 lines, the density requirement dictates that at
least one out of every 16 bits must be a one (see AT&T Technical Publication 62411).
Another way of stating this is that no more than 15 consecutive zero bits can occur
anywhere in the data stream.
T1 lines were originally intended to carry voice traffic, wherein the digitized voice
signals could be altered to meet the ones-density requirement by forcing every eighth
bit of a voice channel to be a one. This practice introduces a small—but virtually
35
inaudible—amount of distortion in the voice signal. Digital data streams between
two computers are another matter, since the corruption of even one data bit causes a
packet to be rejected. Note that in a typical data packet it is quite easy to produce bit
patterns that violate the ones-density requirement. A random file could easily
contain a sequence of bytes that would produce 16 or more consecutive zero bits if
transmitted serially.
There are many different schemes for circumventing the ones-density requirement.
The most common technique simply reserves every eighth bit of the signal for a
“density bit” and forces this bit to be a one. Obviously, these bits are not available for
data transmission, which means that 12.5 percent of the bandwidth of the T1 line is
wasted. When you consider that the lease cost for a coast-to-coast T1 line can be
exceedingly expensive, this waste of bandwidth can be unacceptable. There are
alternatives.
Bipolar with 8-Zero Substitution
One of them uses a special code that transmission equipment can generate when
using the AMI signalling scheme. This special code depends on the fact that two
successive one bits that are represented by pulses of the same polarity result in a
signal known as a “Bipolar Violation.” A CSU can be designed so that it will
automatically replace any string of eight consecutive zeros with a special code
pattern that contains two of Bipolar Violations. A compatible, receiving CSU
recognizes this special code and converts it back to a pattern of eight zeros. This
technique is known by the acronym B8ZS, which stands for Bipolar with 8-Zero
Substitution.
All CEPT lines (the European equivalent of T1) mandate the use of a variant of B8ZS
that holds the density requirement down to no more than three consecutive zeros.
However, telephone companies in North America have been slow to adopt B8ZS,
because it would entail a significant capital investment. Therefore, the B8ZS solution
will not solve the ones-density problem in the short term.
HDLC Zero Insertion Algorithm
An alternative to B8ZS—an alternative used by the SunHSI/P product—makes use of
the fact that the HDLC framing rules specify that any data stream that contains five
or more consecutive one bits requires that the transmitting end insert a zero bit after
the fifth one bit. This guarantees that the HDLC flag pattern 01111110 (hex 7E) does
not occur randomly inside a frame. The receiving end must automatically discard the
zero bit that follows a pattern of five consecutive ones. So, HDLC framing, which is
used by SunHSI/P, guarantees that, except for the flag pattern, in any set of six bits,
at least one bit will be a zero. If you include the flag pattern, you can say that in any
set of seven bits, at least one bit will be a zero.

By inverting the data signal with HDLC framing on both ends of a link, the HDLC
zero insertion algorithm becomes a ones insertion algorithm. This guarantees that in
any set of seven bits, at least one bit will be a one. Thus, the HDLC data stream meets
the density requirements of North American T1 lines without sacrificing any
bandwidth.
Clock Signal Inversion
The need to invert clock lines is separate from the need to invert data lines. Most
computer, modem, and terminal vendors adhere to an industry standard
specification known as RS-334. This specification defines the relationship between a
data bit and a reference clock on a synchronous serial link. The specification also says
that a device should transmit data with reference to the rising edge of the clock
signal and that data should be received with reference to the falling edge of the clock
signal.
When using long cables or cables not carrying a clock signal, a phase shift may occur
causing a high number of errors. In such cases, inverting the clock signal may correct
the phase shift. You may also need to invert the clock signal when connecting a
SunHSI/P port to equipment not adhering to the RS-334 standard.

SunVTS Diagnostic Testing
The SunVTS software executes multiple diagnostic hardware tests from a single user
interface, and is used to verify the configuration and functionality of most hardware
controllers and devices. The SunVTS software operates primarily from a graphical
user interface, enabling test parameters to be set quickly and easily while a
diagnostic test operation is being performed.
Refer to the SunVTS documents (see

Viewing the Man Pages
The following man pages are included with the SunHSI software:
■ hsip(7d)
■ hsip_init(1m)
■ hsip_loop(1m)
■ hsip_stat(1m)
If you cannot view these man pages, you need to add the /opt/SUNWconn/man/
directory to your MANPATH environment variable. Depending on the UNIX shell you
are using, this variable might be defined in one of a number of startup files.
Man Pages
▼ To View Man Pages in the C Shell Environment
1. Examine your $HOME/.login and $HOME/.cshrc files to locate the MANPATH
variable.
2. Using a text editor, add the following line to the end of the file containing the
MANPATH variable.
setenv MANPATH “/opt/SUNWconn/man/:$MANPATH”
41
If neither of the files in Step 1 contains the MANPATH variable, add the following
line to the end of one of the files, or contact your system administrator for
assistance.
setenv MANPATH “/opt/SUNWconn/man/”
3. Use the source command on the file you edited to make the changes effective in
your current window.
For example, if you added the MANPATH line to the .login file, you would type:
hostname% source $HOME/.login
Note – If you log out and then back into your system, you update the MANPATH
variable in all command windows and shells.
▼ To View Man Pages in Bourne or Korn Shell
Environments
1. Using a text editor, add these two lines to the end of the $HOME/.profile file.
MANPATH=/opt/SUNWconn/man:$MANPATH
export MANPATH
If this file did not already contain this variable, add the following two lines to the
end of the file, or contact your system administrator for assistance.
MANPATH=/opt/SUNWconn/man
export MANPATH
2. Make the changes effective in your current window.
$ . $HOME/.profile
Note – If you log out and then back into to your system, you update the MANPATH
variable in all command windows and shells.
