An Important Note to the Reader

For simplicity, we wrote this manual as if for the ANET-1 A only. This is not so; this
manual is for users of the ANET-1 also. Any reference to ANET-1 A throughout the
manual refers to ANET-1 as well.

However, certain information contained inside is not applicable to ANET-1 users be¬
cause the ANET-1 has no twisted pair (TP) port.

Please take note of the following:

o Figure 1 on page 5

The component layout for the ANET-1 is exactly the same is that for the
ANET-1 A but without jumper blocks J5, J6, J7 and the twisted pair (TP)
port.

o Section 5.5 and 5.6 on page 10 and 11 respectively

Both these sections are not applicable to the ANET-1.

Chapter 1
Introduction

The ANET-1A (Rev.K) is an 8-bit network adapter which conforms to Datapoint's
ARCnet Token Passing Protocol. It is the successor to the older ANET-1A (Rev.12).
But unlike the ANET-1A (Rev.12), the ANET-1A (Rev.K) makes use of the new high­performance ASIC controller chip, the COMPEX 91016.

Its half-card design allows the user to fit the card into any expansion slot of an IBM
PC/AT, IBM PC/XT, 386 and all fully compatible systems.
As an ''all-in-one" adapter, it can be configured in a bus or star topology while using
either coaxial cable or unshielded twisted-pair wire as its transmission media. The
default parameters of the adapter can be altered to support widely used network
operating systems such as NetWare. Designed with only one controller and simple cir¬
cuitry, the adapter is easy to configure and install.

With a boot PROM option installed, ANET-1A (Rev.K) makes it possible to connect
diskless PCs to an ARCnet network.

The remote reset PROM or diskless boot PROM allows workstations without floppy
disk drives to boot up on the network. The remote reset PROM must be installed into
the empty socket of the ANET adapter used in a diskless station.

Locate the empty remote reset PROM socket on the ANET adapter.

Notice the notch on one end of the remote reset PROM, and also the circle (or notch)
on one end of the PROM socket. Position the PROM over the PROM socket so that the
notch on the PROM is aligned with the notch on the PROM socket.

Then, place the PROM on the socket and ensure that the pins on the PROM are
aligned with the pin receptacles in the PROM socket. Gently push the PROM all the
way down into the socket and be careful not to bend the pins on the PROM.

Station Address Selection - Dip Switch SW1

Chapter 5
Configuring ANET-1A

A single 8-position Dip Switch (marked as SW1) is provided on the ANET-1A to allow
the user to define the address of each network workstation in which a adapter is in¬
stalled. As a general rule, the address selection for the address of each adapter within
the same network has to be non-zero and unique, i.e. no two ANET adapters should
have the same address setting.

The setting on switch SW1 is the station's address represented in Binary form.
Position "1" represents the LSB (or Least Significant Bit) of the address while position
"8" represents the MSB (Most Significant Bit). "ON" represents a binary "0" for the
corresponding bit of the station address. "OFF" represents a binary "1".

The following example illustrates how an address of 31 in hexadecimal (base 16)
notation is set.

In this chapter, factory-preset defaults are asterisked (*). Specified jumpers can be
located in Figure 1.

In the following text, to “short" a jumper means to place the jumper so that it covers
both the pins, whilst to "open" a jumper means to place the jumper so that only one of

the pins is covered.

NOTE:

In a Bus network topology, the adapter cards of the fwo end worksta¬

This external terminating resistor comes in the form of the Coaxial BNC
terminator or the RJ-11 terminator when the transmission medium is
Coaxial cable or Twisted-pair (TP) wiring respectively.

However external terminating resistors are not required when using the
ANET-1A (Rev.K). This is because the ANET-1A (Rev.K) possesses an
on-board terminator which is connected by shorting jumper J7.

Activity LED indications

Two activity LED indicators are mounted on the rear bracket of the ANET-1A (Rev.K)
adapter. They are the RX(green) indicator and the TX(red) indicator. These indicators
show the functional state of the adapter as follows :

RX(green) - Activated state indicates adapter receiving data from network.

TX(red) - Activated state indicates transceiver on the adapter is active.

o Regular blinking indicates a LAN is disconnected or no other

network node is active.

o ON indicates a LAN cable is connected to an active ARCnet

network, resulting in regular token passing.

Chapter 8
Installing the Adapter Card in the Network Station

Appendix I
The Jumpers Utility

After setting the dip-switch, and the jumpers, the adapter card is ready to be installed
into the appropriate network stations.

Steps to be taken when installing the card

1. Turn off all the power to the station and any attached peripherals.

2. Remove the cover of each station according to the manufacturer’s instructions.

3. Remove the dummy bracket from the back of the computer.

4. Slide the adapter card into the rear bracket slot and firmly press the adapter
card down into the edge connector slot.

5. Fasten the mounting bracket of the adapter card by replacing the holding
screw.

6. Finally, replace the cover of the computer.

The Jumpers Utility (JUMPERS.EXE) can be used to choose the various combinations
of I/O base address, interrupt request (IRQ), and memory address (RAM ADDR) set¬
tings that are not listed in the Configuration Table (option table 6.1) during server and
workstation configuration operations (for NetWare v2.1x, NETGEN and SHGEN; for
NetWare v2.2, INSTALL and WSGEN). This is done by executing the JUMPERS.EXE
file on the NET$OS.EXE(for v2.2) or NET$OS.EX1 (for v2.1x) or IPX.COM file. However,
this utility can be used only if the "Driver Configurable by Jumpers Utility" option is
selected for LAN Driver Configuration during NETGEN or SHGEN. (Refer to the option
table 6.1 for the various possible settings.)

EXECUTING JUMPERS.EXE
The following steps should be noted when executing JUMPERS.EXE.

1

Besides JUMPERS.EXE, the following files are required in order to ex¬
ecute the Jumpers Utility:

o JUMPERS.HLP
o IBM$RUN.OVL
o CMPQSRUN.OVL
o $RUN.OVL
o SYS$MSG.DAT
o SYS$ERR.DAT

The JUMPERS.EXE and JUMPERS.HLP files are found in the COMPEX
driver diskette that comes with the adapter. The remaining files are found
in the SHGEN-1 diskette (for v2.1x) or the WSGEN (for v2.2). Copy these
files into a directory (e.g., JUMPERS) and set a path to this directory.

Fxecutina Jumpers Utility on NETSOS.EX1 (Netware v2.1xl

To execute the Jumpers Utility on a NetWare v2.1 server file
(i.e.,NET$OS.EX1), proceed with NETGEN -n. When selecting the "LAN
Driver Configuration" option, choose the option "Driver Configurable by
Jumpers Utility", and continue with the remaining selections. Exit NET¬
GEN without executing "Installation".

The NET$OS.EX1 is created in the OSEXE-1 directory. Change directory

("cd") to OSEXE-1 and run JUMPERS.EXE (type "jumpers" and press
<enter>). When prompted for the file, enter "NET$OS.EX1". Then select

the adapter used (i.e., ANET-1A (Rev.K) or ANET16-1A) and also the

IRQ#, I/O# and Memory# options. Save and then exit the jumpers utility.

The NET$OS.EX1 file will then be patched with the selected IRQ, I/O and

Memory settings.

You may then continue with the "NetWare Installation" process by run¬

ning NETGEN -c, or begin executing OSEXE-1\NET$OS.EXE.

Executino Jumpers Utility on NETSOS

To execute the Jumpers Utility on a NetWare v2.2 server file (i.e.
NETSOS.EXE), begin by running INSTALL-E. When asked "Will this
machine be the server?", select "No". Under the Network Configuration
option, select "Driver Configurable by Jumpers Utility". After completing
all remaining selections, press <F10> to link NetWare v2.2 utilities and
operating system. This first part of the installation should then exit to the
DOS prompt.

Now create a path to the WSGEN directory. Change the current directory

("cd") to ihe OSEXE directory. Run JUMPERS.EXE from the OSEXE direc¬
tory. When prompted for the file to modify, select NETSOS.EXE. Then
select the adapter used (i.e., ANET-1A (Rev.K) or ANET16-1A) and

proceed to select the IRQ#, I/O# and Memory# options. Save and then

.EXE (NetWare v2.21

exit the Jumpers Utility. The NETSOS.EXE file will then be patched with
the selected IRQ, I/O and Memory settings.

You may continue with the "NetWare Installation" procedure by running
INSTALL-L.

WARNING : Do not use the INSTALL-N and

INSTALL-C options if you are
going to use the Jumpers Utility
settings.

Executing Jumpers Utility on IPX.CQM

To execute the Jumpers Utility on IPX.COM, begin by generating

IPX.COM in accordance with instructions given in the relevant NetWare
manuals (i.e., use WSGEN for v2.2, or SHGEN FOR V2.1x). When select¬
ing the "LAN Driver Configuration" option, choose the option "Driver Con¬
figurable by Jumpers Utility", then continue with the IPX.COM generation.
When IPX.COM is successfully generated, it will be in SHGEN-2 (for
v2.1x) or WSGEN (for v2.2). Change the current directory ("cd") to
SHGEN-2 (for v2.1x) or WSGEN (for v2.2) and execute JUMPERS.EXE.

When prompted for the file to be modified, enter "IPX.COM" and proceed
with the selection of IRQ#, I/O# and Memory# options. Save and exit the
Jumpers Utility. The IPX.COM file will then be patched with the selected
IRQ, I/O, and Memory settings.

You may then copy the IPX.COM file to the workstation diskette. •
