AST 5251/12 REMOTE GATEWAY INSTALLATION
|
|
|
|
|
|
PURPOSE: To remotely attach multiple network nodes to an IBM mini (IBM
|
|
System 34, 36, 38 and AS/400) while only installing one
|
|
emulation card.
|
|
|
|
REASON: Cost effective way to have multiple nodes access emulation
|
|
while only having one emulation card and additional gateway
|
|
software.
|
|
|
|
HARDWARE
|
|
REQUIREMENTS: AST 5251/12 (CC-432 Adapter) Emulation Package. A NETBIOS
|
|
Compatible Local Area Network already installed and
|
|
operational. Synchronous Modems (NOT HAYES COMPATIBLE)
|
|
|
|
SOFTWARE
|
|
REQUIREMENTS: 5251/12 Emulation Version 4.30 (part number 910408-001,
|
|
910408-002 and 910408-003). 5250 Gateway Option Version 4.30
|
|
(part number 910411-001)
|
|
|
|
NOTE: Versions of both 5251/12 Emulation Software and 5250
|
|
Gateway Software may be updated in the future.
|
|
|
|
HARDWARE
|
|
SET UP: AST 5251/12 Adapter IRQ=2; I/O=300-30F (DEFAULT)
|
|
|
|
The above settings are factory default. If a conflict arises
|
|
with other hardware in the PC, the user should consult with
|
|
the conflicting hardware's reference manual for the settings
|
|
and change the AST hardware and software, or vice versa, in
|
|
order to resolve the conflict.
|
|
|
|
For installing and connecting the two Synchronous Modems
|
|
please refer to the Modem Manual, the AST 5251/12 User's
|
|
Manual (part number 000427-001A) and the AST CC-432 User's
|
|
Manual (part number 000140-001E) for more information.
|
|
|
|
Note: This document assumes that the user is qualified to
|
|
establish a successful Modem connection with the IBM
|
|
Host.
|
|
|
|
INSTALLATION: The Master PC contains the AST CC-432 Synchronous
|
|
Communications Adapter, the 5251/12 Emulation program, the
|
|
5250GATE.EXE program which is attached to the network. The
|
|
Slave PC contains the KERNELGW.EXE program which is attached
|
|
to the network.
|
|
|
|
A. MASTER PC CONFIGURATION
|
|
|
|
1. Type the following at the DOS prompt for the directory that
|
|
contains the AST 5251/12 Emulation Software:
|
|
|
|
C:\AST> CFG5251 [Enter]
|
|
|
|
This assumes that the subdirectory name is AST and is located on
|
|
the C: Drive.
|
|
|
|
2. Answer (n)o for MASTER CLUSTER.
|
|
|
|
3. Answer (n)o for ASYNC DIAL UP.
|
|
|
|
4. Answer (y)es for MASTER GATEWAY.
|
|
|
|
5. Answer (n)o for QUICK START.
|
|
|
|
6. From the AST 5251/12 Configuration Program (CFG5251.EXE) menu,
|
|
highlight EDIT and press [Enter].
|
|
|
|
7. Answer (y)es to modify the configuration file, AST5251.CFG.
|
|
|
|
8. The EDIT 5250 CONFIGURATION menu will appear with the
|
|
following options:
|
|
|
|
HARDWARE KEYBOARD STATION SECURITY VDISK CUSTOMIZE
|
|
CLUSTER GATEWAY QUIT
|
|
|
|
9. Highlight HARDWARE and press [Enter]. These options will
|
|
appear:
|
|
|
|
HARDWARE DSP_ADAPTER QUIT
|
|
|
|
10. Select HARDWARE again. This is the HARDWARE selection. All
|
|
the options in this section pertain to how the emulation
|
|
adapter and communication line is configured.
|
|
|
|
IRQ BPS NRZI I/O_ADR TRACE SDLC QUIT
|
|
|
|
11. The BPS, NRZI, TRACE and SDLC options are not set from AST
|
|
(default factory settings). The user must set each option
|
|
accordingly.
|
|
|
|
12. The BPS option pertains to the baud rate of the Synchronous
|
|
Modem that the user is connecting to the AST CC-432 (AST
|
|
5251/12) Communications Adapter. Under this option the
|
|
following list will appear and the user should select the
|
|
correct rate:
|
|
|
|
1200 2400 3600 4800 6000 7200 8000 9600 QUIT
|
|
|
|
13. The NRZI option is host (IBM System 34, 36, 38 or AS/400)
|
|
controlled. This is IBM's error correction detection system.
|
|
It is either ON or OFF. The user must verify this parameter
|
|
with the host's system operator.
|
|
|
|
14. Under the TRACE option these options will be displayed:
|
|
|
|
NONE SNA SDLC QUIT
|
|
|
|
Note: It is recommended that the TRACE option be used as this
|
|
is a good trouble shooting tool. With this option
|
|
selected the user will observe a fixed set of numbers
|
|
followed by incremental numbers on the bottom left and
|
|
right hand corners of the display during emulation.
|
|
The numbers on the left bottom corner indicate that the
|
|
AST package is receiving data from the Modem and the
|
|
numbers on the right bottom corner indicate that the
|
|
AST adapter is transmitting data to the Modem.
|
|
|
|
If there are no numbers at either corner then it
|
|
indicates that the Modem is not communicating with the
|
|
AST CC-432 Adapter. Several probable causes for this
|
|
occurring are as follows:
|
|
|
|
A. Bad or wrong type of cable connecting the Modem to the AST
|
|
CC-432 Adapter. User could be using a standard
|
|
asynchronous null Modem RS-232 cable that does not have
|
|
pin 15 (transmit clock) and pin 17 (receive clock)
|
|
connected.
|
|
|
|
B. IRQ or I/O_ADR conflict between other hardware in the PC
|
|
with the AST Adapters.
|
|
|
|
C. Memory resident (TSR) programs such as; fixed disk
|
|
organizers, menu programs, keyboard macro programs, and
|
|
etc., that may conflict with the AST 5251/12 Software.
|
|
|
|
D. The NRZI option does not match between the host and AST
|
|
5251/12 Emulation.
|
|
|
|
15. Highlight SDLC and press [Enter]. This is the controller
|
|
station address configured at the host (IBM System 34, 36, 38
|
|
or AS/400) site. The user must verify this parameter with the
|
|
host's system operator. It is a hexidecimal value and ranges
|
|
from 01 through FE. Enter the appropriate value and press
|
|
[Enter].
|
|
|
|
16. Press the ESC key and then highlight DSP_ADAPTER and press
|
|
[Enter]. Highlight DSP_ADAPTER on the next screen and press
|
|
[Enter]. Next highlight the type of display adapter you are
|
|
using and press [Enter]. Example: "Color".
|
|
|
|
17. Press ESC until you return to the EDIT 5250 CONFIGURATION
|
|
menu. Highlight STATION and press [Enter], the following list
|
|
will appear:
|
|
|
|
0 2 3 4 5 6 7 8 9 QUIT
|
|
|
|
18. Station Address 0 will always be configured as a 5251/12
|
|
display type. This cannot be changed. Station Address 1 is
|
|
reserved for SNA and is not available. The address scheme for
|
|
the AST 5251/12 Station Addresses and the IBM Host Addresses
|
|
are as follows:
|
|
|
|
STATION option (AST) 0 2 3 4 5 6 7 8 9
|
|
Ports on IBM 0 1 2 3 4 5 6 7 8
|
|
|
|
Respectively for an IBM 5251/12 (what AST is emulating) remote
|
|
controller where all device codes are configured for
|
|
workstation address 0. Page 3-12 of the AST 5251/12 User's
|
|
Manual (AST part number 000427-001) displays this scheme in
|
|
more detail.
|
|
|
|
19. Highlight STATION Address 2 and press [Enter]. These options
|
|
will appear:
|
|
|
|
DISPLAY PRINTER CLUS_DISPLAY CLUS_PRINTER
|
|
GATE_DISPLAY GATE_PRINTER QUIT
|
|
|
|
20. Highlight GATE_DISPLAY and press [Enter].
|
|
|
|
21. Highlight 5251/11 (can also select 5291-1 or 5292-1 but will
|
|
use a 5251/11 for this example) and press [Enter]. Press the
|
|
ESC key when asked to "enter new session name for station
|
|
address 2". For this configuration, session names will not be
|
|
used.
|
|
|
|
22. Repeat steps 19 through 21 as many times as needed to
|
|
configure all the station addresses that will be given to the
|
|
Gateway. In this example a total of seven sessions are
|
|
configured. Make sure that the number of sessions configured
|
|
on the AST 5251/12 software matches the number that the IBM
|
|
host will be allocating to the Gateway.
|
|
|
|
23. Highlight the other addresses and select the appropriate
|
|
DEVICE TYPE and press [Enter]. Configure the station
|
|
addresses as follow:
|
|
|
|
ADDRESS 0 - 5251/12 DISPLAY IBM-API: OFF
|
|
ADDRESS 2 - 5251-1* GATE DISPLAY (NO SESSION NAME)
|
|
ADDRESS 3 - 5251-1* GATE DISPLAY (NO SESSION NAME)
|
|
ADDRESS 4 - 5251-1* GATE DISPLAY (NO SESSION NAME)
|
|
ADDRESS 5 - 5251-1* GATE DISPLAY (NO SESSION NAME)
|
|
ADDRESS 6 - 5251-1* GATE DISPLAY (NO SESSION NAME)
|
|
ADDRESS 7 - 5251-1* GATE DISPLAY (NO SESSION NAME)
|
|
|
|
*The type of display can vary depending on what the host is
|
|
configured for. The other device types that can be emulated
|
|
by the AST 5251/12 software or the 5291-1 and the 5292-1.
|
|
|
|
Note: This sample is configured so the Slave PCs will be
|
|
assigned an address/session on a first-come first-serve
|
|
basis which is called "session bidding".
|
|
|
|
24. When all the required addresses are selected press ESC until
|
|
you reach the AST 5250 CONFIGURATION PROGRAM menu. Now save
|
|
the MASTER/PASSTHROUGH configuration settings and exit to DOS.
|
|
|
|
25. Highlight SAVE and press [Enter].
|
|
|
|
26. The program will ask "Save configuration file: AST5251.CFG
|
|
(Y/N)?" Respond "yes" and press [Enter].
|
|
|
|
This concludes the configuration of the MASTER PC.
|
|
|
|
B. SLAVE PC CONFIGURATION
|
|
|
|
You can use one configuration file for all the network node SLAVES
|
|
provided that all the Slaves have the same type of display. The
|
|
slave software when executed will look at the master configuration
|
|
software to see what gateway displays are available.
|
|
|
|
1. Type the following at the DOS prompt for the directory that
|
|
contains the AST 5250 Gateway Software:
|
|
|
|
C:\GATE\CFG5251G [Enter]
|
|
|
|
This assumes that the software is located in a subdirectory
|
|
named GATE which is on the C: Drive.
|
|
|
|
2. Answer (n)o for QUICK START
|
|
|
|
3. From the AST 5250 CONFIGURATION PROGRAM menu, highlight EDIT
|
|
and press [Enter].
|
|
|
|
4. Answer (y)es to modify the configuration file, AST5251G.CFG.
|
|
|
|
5. The EDIT 5250 CONFIGURATION menu will appear with the
|
|
following options:
|
|
|
|
HARDWARE KEYBOARD STATION SECURITY VDISK CUSTOMIZE
|
|
CLUSTER GATEWAY QUIT
|
|
|
|
6. Highlight HARDWARE and press [Enter]. Highlight DSP_ADAPTER
|
|
and press [Enter]. Highlight DSP_ADAPTER again and press
|
|
[Enter]. Select the appropriate display adapter for this
|
|
particular SLAVE PC (Mono or Color).
|
|
|
|
NOTE: If the Slaves on the network have various types of
|
|
displays (i.e., monochrome and color), different
|
|
configuration files (AST5251G.CFG) will need to be
|
|
created to match each type of display.
|
|
|
|
7. Press the ESC key until you return to the EDIT 5250
|
|
CONFIGURATION menu. Highlight STATION and press [Enter].
|
|
|
|
8. STATION ADDRESS 0 is already configured for you.
|
|
|
|
ADDRESS 0 - 5251/11* DISPLAY IBM-API: OFF
|
|
(NO SESSION NAME)
|
|
|
|
*The device type can also be a 5291-1 or a 5292-1.
|
|
|
|
For this setup you do not need to delete or reconfigure.
|
|
Address 0 on the MASTER PC is taken by the 5251/12 Controller
|
|
so this SLAVE PC configuration would then go to the next
|
|
available session on the MASTER PC which would be address 2.
|
|
|
|
Note: We are setting this up for "session bidding", therefore
|
|
we do not need to configure the exact station address
|
|
for the slave. When the slave software is executed, it
|
|
looks at the master configuration to see which gateway
|
|
display is available. This is called session bidding.
|
|
This is how all the slave configurations should be set
|
|
up for session bidding.
|
|
|
|
9. Press the ESC key until you return to the AST 5250
|
|
CONFIGURATION menu. The user will now save the SLAVE PC
|
|
configuration settings and exit to DOS.
|
|
|
|
10. Highlight SAVE and press [Enter].
|
|
|
|
11. The program will ask "Save configuration file: AST5251G.CFG
|
|
(Y/N)?" Respond (y)es and press [Enter].
|
|
|
|
12. Highlight QUIT and press [Enter].
|
|
|
|
13. Repeat Steps 1 through 12 at each SLAVE PC as needed.
|
|
|
|
This concludes the configuration procedure for the SLAVE PC.
|
|
|
|
C. ENHANCED KEYBOARD CONFIGURATION
|
|
|
|
If you have an Enhanced Keyboard (Function Keys located across the
|
|
top), you need to run an additional configuration program. Without
|
|
running emulation, insert the AST5251/12 Terminal Emulation
|
|
Diskette 2 of 3.
|
|
|
|
1. Type: A:[Enter]
|
|
|
|
2. Type: ASTKBD [Enter]
|
|
|
|
3. Use your down arrow key to highlight the COUNTRY selection.
|
|
|
|
4. Use your left arrow key to highlight the UNITED STATES as
|
|
country type.
|
|
|
|
5. Use your down arrow key to highlight the KEYBOARD selection.
|
|
|
|
6. Use your left arrow key to highlight the ENHANCED-LIKE for the
|
|
keyboard type.
|
|
|
|
7. Use the down arrow key to go to the PROCEED option and press
|
|
[Enter].
|
|
|
|
8. Type the drive letter and subdirectory where the KERNEL.EXE
|
|
file is located for the MASTER PC or where the KERNELGW.EXE
|
|
file is located for the SLAVE PC
|
|
|
|
9. Use your down arrow key to get to the EXIT TO DOS option and
|
|
press [Enter].
|
|
|
|
This should be done for each machine that has the enhanced
|
|
keyboard.
|
|
|
|
