PROTOCOL CONVERTER MODEL A/S-4

1. General Information

THE A/S-4 is an SNA protocol converter. It is capable of a wide variety of conversions and adaptation tasks. Listed below are just a few of the tasks the A/S-4 was designed to perform:

• Bit-oriented protocol, SDLC

• Byte-oriented protocol, ASCII

• Serial Data Transfer and Conversion

• Screen Emulation of various CRTs

• Storage of prompting commands

• Protocol conversions

• Character conversions

• Communication conversions

The A/S-4 is also designed to be easily installed and operated. The A/S-4 hardware consists of the following components:

• 16K of available Static Random Access Memory (RAM) and 32K Non-volatile Erasable Programmable Read Only Memory (EPROM).

• Two (2) Input-Output (I/O) Serial interface ports capable of the following operations:

- async, byte sync, or bit sync

- half or full duplex

- up to 19.2 bit per second data transfer

- automatic CRC generation and checking (CRC-16 or CCITT-16)

- 8 bit address recognition

- automatic zero bit insertion and deletion

- Data Terminal Equipment (DTE) or Data Communication

- Equipment (DCE) operations

- NRZI, TDI or RS232C

• Power, Data Send/Receive, and signal visual LED Indicators

• 6809 Microprocessor control

• 6 switch banks for changing RS232, NRZI, and TDI pin assignments of the serial ports

• 2 switch banks for option selections.

CHAPTER 1:General Information

The A/S-4 is a 3274 work-alike controller emulating a PU2 with one LU2 terminal and one LU1 or LU3 printer. This allows an ASCII terminal or micro computer to emulate a 3278 CRT with a 3278 printer. The A/S-4 will also emulate SNA/SDLC 3776 or 3777 work station with one LU1 console, printer, card reader, card punch, or disk. It should be noted here that for purposes of simplicity this manual refers to CRTs and PCs with the generic acronym VDU: Visual Display Unit.

Either port may be configured as data terminal equipment (DTE) or data communications equipment (DCE). This gives the system designer great flexibility in determining what type devices he will use and where the A/S-4 can be installed.

The A/S-4 is designed to ease installation by the end user. Most of A/S-4’s operating parameters (address, baud rate, ID, word structure, video display type) are “SOFT.” They may be changed from the keyboard using “Friendly” menus to step you through the set up procedure. Once programmed, the A/S-4 retains its settings in non-volatile memory until changed by the user.

CHAPTER 3: Installation

3. Installation

3.1General Installation

The A/S-4’s options are set by the operator through the use of menus and switches. The A/S-4 provides a very flexible package of options so as to work with any terminal or terminal emulating device (such as a personal computer). Due to the great numbers of options provided, it may take a little time to set up the A/S-4 unit, however once complete, the options need not be set up again. All options are battery protected for when the unit is turned off.

The A/S-4 uses external switches and easy to use menu driven Set up features.

The A/S-4 is shipped from the factory ready to run with no changes if a DTE device (VDU, Personal Computer, etc.) is attached to the A/S-4’s terminal port and the A/S-4’s modem port is connected to a synchronous modem for dial up SDLC. If this is not your application, only a few switches need be changed. Refer to Section 4.0 for switch settings of other devices.

To install the A/S-4:

1. Connect cables to devices.

2. Plug in the A/S-4.

3. Type “S” on VDU for automatic speed detection of 300, 1200, 1800, 2400, 4800, or 9600 baud

to obtain A/S-4 menus.

4. Follow A/S-4’s menus.

If you have an odd baud rate not listed, refer to Section 4.0 for setting switches for terminal baud rate. If the menus do not appear, refer to Section 13.0 for trouble shooting problems and odd installations.

3.2 Modem Interface

The modem port can be configured for several types of hardware communications. The A/S-4 is shipped with the options set for the RS232C EIA standard. The modem port can be configured for NRZI for some IBM installations by setting the switch on the rear of the A/S-4 unit to the NRZI position.

3.3 Terminal Automatic Speed Detection

The A/S-4 has the necessary hardware and software for speed detection on the terminal port. This option makes it possible to install a A/S-4 without changing a switch. Baud rates of 300, 1200, 1800, 2400, 4800, or 9600 can be detected on power up of the unit. After applying power, the operator types “S” or SNA on the terminal and the baud rate of the VDU is detected and a power up message is sent to the terminal. The “S” may be in lower or upper case, even, odd, or no parity. Switch 5 of switch bank S9 must be OFF to enable this feature to work properly. The A/S-4 is shipped with this feature ready to work.

PROTOCOL CONVERTER MODEL A/S-4

3.4 Power Transformer

The A/S-4 is shipped with a transformer for the standard USA 110-VAC outlet plug. A substitute transformer may be ordered for the for 220 VAC or other voltages. A conversion plug for different power outlets is the responsibility of the purchaser.

3.5 Synchronizer

The A/S-4 has a unique feature on the modem port to allow the A/S-4 to run SDLC over asynchronous modems, therefore providing a low cost dial up system. This is possible by the use of a hardware synchronizer circuit that derives clocks from the data. To use this feature, set the modem port switches as listed in Section 4.0 for an Asynchronous Modem.

CHAPTER 4: Switches

4. Switches

The A/S-4 is equipped with 8 banks of DIP switches, all of which are accessed from the bottom of the unit. The general functions of these switches are as follows:

Terminal Interface Configuration SW2, SW3, SW6 Terminal Speed SW6 Modem Interface Configuration SW4, SW5, SW7 Terminal Data Formats & Options SW9 Special Printer Interface SW8

NOTE

When any switches are changed, the A/S-4 must be powered off and on for the new switch settings to take effect.

6. Power Up and Configuration Menu Operations

The A/S-4 unit options are mainly set by the operator through the use of menus. The A/S-4 provides a very flexible package of options so to allow any VDU to operate like an IBM 3278 terminal and an IBM 3287 printer or a 3770 work station. Because of the great numbers of options provided, it may take a little time to set up to A/S-4 unit, but once complete, the options need not be set up again. All options are battery protected for when the unit is turned off.

6.1 Power Up

To start installing your A/S-4 unit only the VDU need be connected. Connect to VDU, making sure all the following steps have been followed.

1. Plug in, turn on, boot, or perform any other needed operation to ready the VDU.

2. Set switches SW2, SW3, SW6 on A/S-4 for type of VDU connecting to, see Section 4.2 How to set Terminal Switches for different devices. The factory default switch settings are for a VDU DTE device.

3. Set SW9 for communication options needed, refer to Section 4.5 Option Switches. The factory default switch settings are for 7 data bits, speed detection ON, menu operation ON, even parity. Be sure that SW9/6 is in the ON position: Option change on power up enabled.

4. Plug the power transformer into any standard 110 volt AC power outlet. Plug the connector on the other end of the power cord into the mating connector on the back of the unit. Insert the connector so the small beveled lip faces up for ease of insertion. The beveled lip can be inserted up or down and the unit will work fine with no harm to the A/S-4. A substitute transformer may be ordered for the A/S-4 unit for 220 volts AC or other voltages.

5. Plug an RS232-C cable from the VDU into the terminal connector on the back of the A/S-4. Pins 2-8 and 20 are required.

6. Plug an RS232-C cable from the modem or IBM host into the modem connector. Pins 2-8, 15, 17 and 20 are required.

After the above procedure has been completed, the A/S-4 should have three lights on, the power, TCTS, and TCD. If these lights are not all on the A/S-4 unit will not communicate with the VDU host properly. Refer to Section 11.0 Trouble Shooting Problems and Odd Installation Problems if all three lights will not come on.

With all three lights on, the A/S-4 is waiting for the letter “S” from the VDU for auto speed detection if the option is enabled. The operator types lower or upper case “S” and the A/S-4 will calculate the baud rate and send out a power up message. The A/S-4 is capable of detecting baud rates of 300, 1200, 1800, 2400, 4800 and 9600. If the speed detect option is off, the A/S-4 will send out the power up message two or three seconds after the three lights come on at the baud rate set by switches SW6 (refer to Section 4.1 Terminal Switches). If the power up message does not look like Figure 1, check the option switch SW9 or refer to Section 13.0 Trouble Shooting Problems and Odd Installation Problems. If the message “MEMORY ERROR U13 or U14” is displayed, refer to section 13 to determine if the A/S-4 is defective.

CHAPTER 6: Power Up and Configuration Menu Options

6.2 Power Up Message

The A/S-4 sends out the message in Figure 1 on power up or the raising of DTR (DATA TERMINAL READY) on the terminal device. This message informs the operator that the A/S-4 is ready to try to match the operator’s terminal or terminal emulation package with the VDU (VISUAL DISPLAY UNIT) list in the memory. The operator may now type the “HOME” key on his/her terminal so that the A/S-4 may match the VDU device with the internal VDU list so that the clear screen, home cursor, position cursor commands, etc. to the VDU will be correct. If no match occurs, the A/S-4 defaults to the IBM 3101 VDU command set. This is not a problem if your VDU is not an IBM 3101, as you may change the VDU by the use of menus. If your terminal does not have a home key, you may hit the space bar and set up the VDU by the menus. Hitting the space bar leaves the internal VDU the same as the last VDU used with the A/S-4. After typing “space” or “HOME” the A/S-4 will output the A/S-4’s main menu. If a VDU match did occur, the screen will clear before the main menu is displayed, otherwise the VDU device will scroll.

6.3 A/S-4 Main Menu

A set of menus are used to configure the A/S-4’s options so that it will operate properly with the particular VDU and host to which it is connected. In order to access these menus, SW9/6 must be in the ON position (see Section 4.5). All options are stored in battery-protected RAM so that they need not be reconfigured in the event of interruption of AC power to the unit.

At the beginning of every A/S-4 menu are the current main three options, the application, VDU and keyboard. The application option informs you of which keyboard layout the A/S-4 will use when running SDLC/SNA.

The A/S-4 Main Menu is shown in Figure 2. This menu coordinates the changing of the many A/S-4 options into main categories, VDU Selection, VDU commands, VDU video commands, keyboard selection, keys on keyboard arrangement, application, application options, printer options and verification of switch settings.

6.4 Switching from A/S-4’s Main Menu to Running the Application

Once all operating parameters have been configured properly, the A/S-4 is ready to run. To connect the asynchronous devices to the application, enter the letter “A” for the RUN option of the A/S-4’s Main Menu. The A/S-4 will then proceed to connect up to the application in one of the following manners depending on which of the three states the host communication line is in:

1. Modem not ready; if the modem is turned off or on a dial up line the modem has not been dialed or on a lease line the line is down, the A/S-4 will display on the VDU “DIAL UP SDLC LINE”. Once the phone line connection with the host has been establish the A/S-4 will proceed to one of the following two states. Refer to Section 13.0 on Trouble Shooting if the Dial Up message will not go away for more information.

PROTOCOL CONVERTER MODEL A/S-4

2. Modem connected to host but LU inactive; if the LU is inactive the A/S-4 will display “WAITING FOR LU TO COME ACTIVE”. The LU should come active after a few seconds of this message appearing on the VDU. If the LU does not come active, then one of the following problems may exist:

A. Host is not polling PU (Physical Unit) Solution: Have a network operator activate

the PU and maybe the line also.

B. PU address (or station address) is incorrect Solution: Return to A/S-4 menus and

change PU address.

C. LU address is incorrect Solution: Return to A/S-4 menus and change LU address.

After the LU comes Active, the A/S-4 will proceed to the following state. Refer to Section 13.0 on Trouble Shooting if the LU will not activate for more information.

NOTE

In states 1 and 2 typing any key will return A/S-4 to it’s Main Menu

3. Application running:

Interactive - The A/S-4 will refresh the VDU’s screen with the last screen received from the host (which could be blank). Operation will then function as a 3278 CRT.

Batch - The A/S-4 will display the status of the LU on the status line but no previous data from the system will be displayed on the VDU. Operation will then function as a 3770 work station.

CHAPTER 6: Power Up and Configuration Menu Options

6.5 Changing the VDU Type

If the current VDU type displayed at the top of the A/S-4 Main Menu does not match the VDU or VDU emulation package you have connected to the A/S-4, you may change the VDU type by entering the letter “B” in response to the Main Menu. The change VDU Menu will then be displayed on your screen as in Figure 3. If your screen is scrolling A/S-4 menus instead of clearing the screen before each menu, then you should change the VDU type. The change VDU menu allows you to match your VDU with one of the A/S-4’s fixed VDU types or to create a new A/S-4 VDU type. The A/S-4 feature for creating a new VDU type allows A/S-4 to work with any asynchronous device with screen capabilities.

The change VDU menu allows 4 operations as described below:

1. Exit - By entering the number 1 or the letter A the A/S-4 will return to the Main Menu with the VDU type currently at the top of the screen.

2. Change current VDU type at top of screen - By entering the number 2, the operator may change the VDU type. The A/S-4 will then display “ENTER LETTER:” so that the operator may select the letter preceding the desired VDU type from the list of programmable and fixed VDU types. Fixed VDU types have the VDU commands characters hard coded into the A/S-4’s firmware and require that your VDU or VDU emulator match those commands character for character. Programmable VDU types have VDU command characters stored in battery protected memory so that command characters in the A/S-4 can be changed to match the operator VDU or VDU emulator that is not exactly like any of the Fixed VDU types. After the operator enters the desired letter (A thru J), the menu will redisplay with the new VDU type at the top of the screen using the new command character set of the selected VDU.

PROTOCOL CONVERTER MODEL A/S-4

NOTE

Selection of a blank programmable VDU type may cause erroneous command characters to be sent to the operators VDU. The programmable VDU type should be added by option 3 before it is selected.

3. Add or Change Name - by entering a 3 the operator is able to add a name to or change a name from the “PROGRAMMABLE” column see figure 4. This is done when the operator’s VDU does not match one of the “FIXED” VDU’s and it allows him to define to the A/S-4 the various commands his VDU needs to operate properly (e.g., the command from the A/S-4 which will cause his VDU to clear the screen). In the example shown in figure 4, the operator has given the name “NEW VDU” to VDU A. Operator input is underlined. The 10 characters are filled out with spaces or just type carriage return. By typing the letter “H”, he has copied the characteristics of VDU H into those of “NEW VDU”. The “CURRENT” header will now show the VDU as “NEW VDU”. Using the VDU commands menu (selection C on the Main Menu) he can now change the clear screen command (or any other command) from the command copied from VDU H to whatever “NEW VDU” needs (these commands may be found in the NEW VDU manual).

4. Delete Name - By entering a 4 the operator can delete a name from the “PROGRAMMABLE” VDU list.
