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. 01982 GIMIX Inc. -1- Rev. A

@/29/8~ 0,"1:)- 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. Signal RX TX GND RTS DCD CTS Pin# 2 3 4 5 7 8 12 20 Direction Computer Peripheral <----------< >----------> -----> [ -----> <----------> >----------> <----------< <----------< 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. 01982 GIMIX Inc. -1- Rev. A

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.

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). 01983 GIMIX Inc. -2- Rev. A

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.

OS-9 GMX~ III ~J)I( 06/08/83 - 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. c 1 9 8 3 GIt~ I X Inc. -i- Re v. A
