UNPACKING YOUR GIMIX SYSTEM
11/29/82
To protect your GIMIX 6809 system during shipping, packing material
has been placed INSIDE the system. YOU MUST REMOVE THE TOP COVER AND
ALL OF THE PACKING MATERIAL BEFORE APPLYING POWER TO THE SYSTEM. Remove
the packing carefully and be sure that all of the boards are fully
seated on the motherboard connectors. Check carefully for small parts
that may have been packed inside. In most systems the AC line cord and
keys are packed inside the cabinet. Small parts, such as cables, may
also be packed inside. You should also check the system carefully for
any damage that may have occurred during shipping. If damage is
apparent, contact GIMIX and the carrier immediately.
The system can be operated with the cover removed to facilitate
initial setup and testing; however, we recommend that the cover be kept
in place as much as possible during normal operation to insure proper
cooling. (This is especially important with hard disk systems.)
We suggest that you retain the original box and packing material,
in case it is ever necessary to ship the system.

CONFIGURATION INFORMATION FOR THE GIMIX TWO PORT SERIAL I/O BOARD
This notice outlines the recommended procedure for connecting
serial peripherals (terminals, printers, etc.) to the GIMIX Two Port
RS-232C serial interface board. Failure to follow the recommended
procedure can result in random I/O errors caused by noise pickup on
unused handshake lines (CTS and/or DCD). The errors are most noticeable
on interrupt driven systems (OS-9 and UniFLEX) where noise can cause the
generation of interrupts that cannot be identified by the operating
system.
As shipped, the jumpers on the Two Port serial boards are normally
configured as shown in figure "B" of the "JUMPER CONFIGURATIONS" drawing
included with the board. The following chart shows the DB-25 connector
pinouts for this configuration.

High-speed terminals normally require a simple three wire cable,
without handshake, connecting pins 2,3, and 7 of the I/O board to the
corresponding pins on the terminal. THE UNUSED HANDSHAKE INPUTS (DCD
and CTS) MUST BE PROPERLY TERMINATED TO PREVENT NOISE PICKUP. It-rs
especially--Important to terminate these inputs if a 25 conductor cable
is used.
There are two recommended methods for terminating DCD and CTS. The
first is to REMOVE (from JA-1 and/or JA-2) the jumpers that connect DeD
and CTS to the I/O cable. These jumpers MUST BE REMOVED even if the
corresponding pins on the I/O connector are unconnected since even the
length of cable from the board to the back-panel connector is sufficient
to pick up noise from the system. PUll-up resistors on the board force
the inputs to the required active level for proper operation of the
board. This method should be sufficient in most cases.

The second method connects the RTS output from the board to the DCD
and CTS inputs. Using the output driver (RTS) to hold the handshake
inputs at the proper level. Caution: This method will only work if the
software initializes the RTS output of the ACIA to the active level.
Operating systems supplied by GIMIX (FLEX, OS-9, and UniFLEX) initialize
the ACIA properly. Software from other sources, that directly accesses
the ACIA, should be checked for proper initialization. There are two
ways to implement this method, depending on the type of cable used to
connect the board and the peripheral. If a discrete-wired cable is
used, jumpers can be installed in the connector at the computer end of
the cable, to connect RTS, CTS, and DCD together. (In the case of the
jumper configuration shown above, pins 8, 12, and 20 would be connected
together) If a mass-terminated or ribbon type cable is used, the jumpers
for RTS, DCD, and CTS can be removed from JA-1jJA-2 and wire-wrap
techniques used to connect RTS, DCD, and CTS together at the jumper
strips.
Printer interfaces normally require handshake to prevent the
computer from outputting data faster than the printer can accept it.
Software provided by GIMIX uses the CTS input to the serial board for
printer handshaking. The CTS input must be connected to an output from
the printer that is high (positive level) when the printer is ready to
accept data and low (negative level) when it is not ready. The DCD
input is not used in this application and should be terminated as
described in the preceding section. If printer handshake is not
required (if, for example, the baud rate will be set slow enough to
prevent printer over-run) the CTS input should also be terminated as
described above. Note: Some serial printers require that their
handshake inputs (DSR/DCD) be placed in an active state before they will
accept data. This can usually be accomplished by connecting an unused
output from the printer (DTR) to its handshake inputs, at the printer
end of the cable. See the example diagrams below and the printer
documentation.

being the maximum recommended length.
Shielded cable may be required if radio interference is
a problem.

* PU is an active (high) level output that can be
used to hold unused inputs at the active level.
High-speed terminals normally require a simple three wire cable,

The second method connects the PU output from the board to the
unused inputs. Using the output driver (PU) to hold the handshake
inputs at the proper level. There are two ways to implement this
method, depending on the type of cable used to connect the board and the
peripheral. If a discrete-wired cable is used, jumpers can be installed
in the connector at the computer end of the cable, to connect PU, CT5,
D5R,
and DCD together. (In the case of the jumper configuration shown
above, pins 4, 8, 11, and 20 would be connected together) If a
mass-terminated or ribbon type cable is used, the jumpers for PU, D5R,
DCD, and CT5 can be removed from the jumper areas and wire-wrap
techniques used to connect the appropriate pins together at the jumper
strips.

PU (pin 11) used to
hold unused inputs
at the active (high)
level for better
noise immunity.
Some terminals may require handshake at higher baud rates (usually
9600 and above; consult the terminal manufacturer's documentation).
This is usually available in one of two forms, hardware or software
(X-ON/X-OFF). If hardware handshake is required the appropriate output
from the terminal should be connected to one of the inputs (D5R or DCD)
as described in the following section on printer connections. If
X-ON/X-OFF is required the standard configuration shown above can be
used. Caution: Before using X-ON/X-OFF, check the software
documentation to determine if it is supported and if special software
configuration is necessary. GIMIX/05-9 software supports X-ON/X-OFF but
it must be enabled by making the appropriate changes to the Device
Descriptor(s).

Printers normally require handshake to prevent the computer from
outputting data faster than the printer can accept it. Software
provided by GIMIX uses either the DCD or DSR inputs for printer
handshaking. One of these inputs must be connected to an output from
the printer that is high (positive level) when the printer is ready to
accept data and low (negative level) when it is not ready. The CTS
input should not used in this application and should be terminated,
along with the other unused input (either DCD or DSR), as described in
the preceding section. If printer handshake is not required (if, for
example, the baud rate will be set slow enough to prevent printer
over-run) all three inputs should be terminated as described above.
Note: Some serial printers require that their handshake inputs (DSR/DCD)
be placed in an active state before they will accept data. This can
usually be accomplished by connecting an unused output from the printer
(DTR) to its handshake inputs, at the printer end of the cable. See the
example diagrams below and the printer documentation.

* Pin 8(DCD) may also be used as the handshake input.
Some printers may use software (X-ON/X-OFF) handshake for
start/stop control. In this case connection must also be made between
pin 2 of the computer and pin 2 of the printer to provide the reverse
channel for handshaking. See the software documentation for information
on the availability of X-ON/X-OFF.

Most existing software designed for use with OS-9~ Level II will
function properly on GMX~ III systems, without modification. However,
it may be necessary to obtain updated versions of some programs. The
GMX~ III system has been instrumental in identifying and locating many
bugs in existing software. To date the software vendors have been very
cooperative, and in most cases these bugs have been or are being
corrected. If you encounter problems, especially trap errors (#197,
#198, or #199), contact the software vendor for information on current
versions for use with GMX III.
Single character I/O and GIMIX intelligent I/O boards.
GIMIX intelligent I/O boards and the "lOP" drivers fully support
single character I/O, using the same conventions as the standard I/O
drivers. Existing software that uses single character I/O will work
with the intelligent I/O boa~ However, software that makes-exfensive
use-or-5ingle character-output (e.g. certain text editor/processors)
will not perform as well as the same software using line oriented
character output. Early versions of both Dynastar and Stylograph used
single character output; however, versions that use line oriented output
are now available. Note: systems that do not use intelligent I/O boards
can also benefit from the use of line rather that character oriented
output.
