Features and Specifications
Introduction

Tiger Cub System Concept

The ITOX Tiger Cub uses state-of-the-art design to provide a compact,
low cost PC platform for Computer Telephony and industrial applications
that require multiple, full length ISA interface cards.

The Tiger Cub is designed for unattended operation in light industrial
environments. It is packaged in a small industrial enclosure that can be
mounted on a wall or placed on a shelf or table. It is designed for turnkey
systems that utilize auto-executing DOS application programs. Conse­quently, there is no need for a keyboard, mouse, video display or floppy
disk in operational systems, and the most reliable, cost effective solution
is achieved by not providing these items.

One of the Tiger Cub serial ports can be used to control the Tiger Cub
during application development, diagnostic testing and for loading
programs onto the Tiger Cub’s hard disk. An on-board watchdog timer
supports reliable operation in unattended applications by restarting the
system automatically if the software hangs-up.

Specifications

The Tiger Cub’s processor and memory chips are soldered in place on the
motherboard. Consequently, the processor speed and memory size must
be specified at the time of order.

System Configuration

The basic Tiger Cub is configured with a 33 MHz processor and 4 MB of
RAM memory. Higher speed processors and/or 8 MB of RAM are
available as factory installed options.

Several disk storage options are available and are not included in the basic
configuration. Available options include 24 MB Disk-on-Chip Flash disk
and 3 ½” hard drives of various capacities.

The Disk-on-Chip may be configured as the first (boot) drive or the last
drive. The Tiger Cub’s internal IDE disk controller will support one primary
drive and one slave drive.

The flash disk chips mount in sockets provided on the motherboard. Hard
drives are mounted in a removable disk tray for easy assembly. The
removable disk tray feature also allows field application software upgrades
to be performed by shipping the user a preloaded hard drive mounted in a
spare disk tray.

Floppy drives are not typically used with the Tiger Cub. However, applica­tions requiring a floppy drive can be accommodated by installing a 3 ½”
floppy drive in the externally accessible drive bay and installing a floppy
drive controller card in one of the Tiger Cub’s ISA expansion slots.

The Tiger Cub is supplied with the Datalight ROM-DOS 6.22 operating
system in the basic configuration. Optionally available operating systems
include Microsoft MS DOS 6.22, IBM PC DOS 7.0, and Caldera DR-DOS.

10

Introduction

The Tiger Cub is designed to allow console redirection through the serial
port (COM1) for loading software and local control/debugging of applica­tion programs. This is accomplished by connecting COM1 of the Tiger
Cub to the serial port of a notebook computer or other device with a null
modem cable. The appropriate procedures are provided in Chapter 3
and Chapter 5 of this manual.

Tiger Cub User’s Manual

II. Hardware Installation and Set Up

Caution: Always unplug the AC power cord from the Tiger Cub before
opening the cabinet to prevent possible contact with the rotating fan
blade or hazardous voltage. The Tiger Cub is designed so that all high
voltage components remain enclosed in the lower portion of the cabinet
when the access panel is removed. However, contact with potentially
hazardous voltage is possible if tools or screws enter the lower portion
of the case through the cable or cooling holes.

Set Input Voltage Selector Switch

The Tiger Cub is equipped with a dual range power supply for operation
with AC input voltage from 100 to 240 VAC at 50/60 Mz. Set the AC
voltage selector switch on the rear panel of the Tiger Cub to the appropri­ate postion based table below.

AC Voltage Switch Settings

Normal Input Voltage Switch Setting

100-120 Vac 115
200-240 Vac 230

Removing the Access Cover

Remove the six screws on the side of the Tiger Cub cabinet (five on one
side & one on the other side) and remove the access cover to install
expansion cards and set jumpers. The Tiger Cub is supplied with a
retaining bracket to hold expansion cards in place. Remove the screw at
each end of the bracket and remove the bracket to provide access for
installing expansion cards.

Installing Expansion Cards

Warning: Electrostatic discharge (ESD) can damage your
processor, disk drives, add-in boards, and other components.
Perform the instruction procedures described at an ESD
workstation only. If such a station is not available, you
can provide some ESD protection by wearing an antistatic
wrist strap and attaching it to a metal part of the system

14

Hardware Installation and Setup

chassis. If a wrist strap is unavailable, establish and maintain
contact with the system chassis throughout any procedures
requiring ESD protection.

The Tiger Cub is designed to accept three full length, full height expan­sion cards utilizing the 16 bit ISA interface standard. Remove the appro­priate number of filler plates from the back of the unit, install the cards in
the normal manner, and secure them in place with the screw previously
used to hold the filler plate in place.

The retaining bracket should be replaced after the cards have been
installed. Then the black plastic pads supplied with the unit should be
installed in the square holes in the bracket and positioned with the edge
of the expansion card in the “V” groove of the pad. Install the screws
supplied with the pads into the bracket so that they press on the pads at
an angle to hold the expansion cards firmly in place. The access cover
should be replaced after the jumpers have been set. See appendix A for
the correct jumper setting for your system configuration.

Installing Disk Drives

The Tiger Cub uses a removable disk tray for quick and easy mounting of
hard (and floppy) disk drives. Disks ordered from ITOX at the same time
as the Tiger Cub will be pre-loaded with the appropriate software and pre­installed in the unit. This procedure should be followed for disks not
installed by ITOX.

2

1. Pre-load your software onto the hard drive.
The hard drive must be loaded with the operating system including the
appropriate file loading utilities identified in Chapter 5 (not required if the
Tiger Cub has a floppy drive). Most users will find it convenient to pre­load all software required for the application at the same time.

2. Remove the drive tray from the front panel of the Tiger Cub.
It is not necessary to remove the access cover to install disk drives.

Verify that the Tiger Cub power cord is disconnected from the AC
voltage source. Remove the two phillips head screws located closest to

the outside edges of the lower portion of the front panel. Then
slide the drive tray out the front of the unit.

15

2

Tiger Cub User’s Manual

3. Install the drive(s) in the drive tray.
The drive tray includes slots for mounting up to three 3 ½ “ disk drives.
Select the set of slots you want to use and mount the drive according to
the manufacturer’s instructions. The center drive position has a knock­out section that can be removed to provide exterior access to the drive.
This position is typically reserved for floppy drives. Remove the knock­out before installing any of the drives if a floppy drive will be installed.

4. Connect the data and power cables.
Reach into the lower portion of the Tiger Cub case through the opening
where the drive tray mounts. Gently guide the power cable and ribbon­type data cable through the opening so they can be connected to the disk
drive. The connectors are keyed for proper attachment; make sure that the
connectors are attached to the drive in the proper orientation.

5. Install the drive tray back into the Tiger Cub case.
Slide the drive tray back into the case; guide the cables into the opening
while doing this to keep them away from any sharp edges and insure they
remain fully engaged. Secure the drive tray in place with the two screws
removed in step 2 above.

6. Specify the correct hard disk type in the BIOS setup.
Complete any other hardware installation procedures before power is
applied to the unit. Enter the correct hard drive type (from disk manufac­turer’s instructions) in the Basic CMOS Configuration section of the BIOS

setup (see Chapter 4).

Wall Mounting the Tiger Cub

The Tiger Cub is designed to be placed on a shelf, table or other flat
surface, or wall mounted. Rubber feet are provided for table top operation.
Four key-hole shaped mounting holes are provided in the side of the
Tiger Cub for wall mounting. Use of all four wall mounting points is
recommended and will result in the most secure installation; at least one
of the front brackets and one of the rear brackets must be used to provide
adequate support. A template for installing the mounting screws in the
wall is provided in the Tiger Cub box.

The Tiger Cub mountings have a protective back plate that prevents
narrow objects from entering the case. The mounting holes are designed
to slip over the heads of screws mounted in the wall or other vertical

16

Hardware Installation and Setup

surface upon which the Tiger Cub is to be mounted. The holes are
designed for ¼ inch (6 mm) pan head screws, but can be used with any
screws with a head diameter between 0.35 inch (9 mm) and 0.55 inch (14
mm) and a maximum head height of 0.2 inch (5 mm). The screws should be
installed to allow a clearance of 1/16 inch (1.5 mm) under the screw head
to provide clearance for the thickness of the mounting bracket.

Once the screws are installed in the wall to the proper depth, place the
Tiger Cub mounting holes over the screw heads and then slide the Tiger
Cub down to secure it in place. It can be removed for servicing by sliding

the unit up and lifting the unit off the screw heads.

Tiger Cub User’s Manual

File/Software Loading

Files are typically loaded onto the Tiger Cub from a notebook or
desktop PC via a null modem cable using file transfer utility
programs provided with DOS. Data is transfered at a rate of up
to 57600 bps. The Tiger Cub acts in a server capacity by
making its hard drive available to the notebook PC. The note­book PC is considered the client and can then access the drive
to load files onto it from the other drives of the notebook PC.

The appropriate file transfer programs for the available DOS
operating systems are shown below:

DOS Operating System Server Program (T. Cub) Client Program

Datalight ROM-DOS REMSERV.EXE REMDISK.EXE
Caldera DR-DOS FILELINK.EXE FILELINK.EXE
IBM PC-DOS INTERSRV.EXE INTERLNK.EXE
Microsoft MS-DOS INTERSRV.EXE INTERLNK.EXE

The appropriate operating system with the server program will
be preloaded on the Tiger Cub drive if both the operating system
and the drive were purchased from ITOX. Drives not purchased
from ITOX should be preloaded with the appropriate operating
system prior to installing them in the Tiger Cub.

The client program can be run directly from the floppy drive of
the notebook PC using the floppy disk provided with the Tiger
Cub system.

The following steps illustrate the procedure for loading software
with the MS-DOS or PC-DOS operating system located on the
floppy drive of the notebook PC. The procedure for the other
DOS operating systems is similar.

(Notebook PC)

J6, J8 - Watchdog Timer

The Tiger Cub has a watchdog timer that can be set to automati­cally reboot the system if it hangs up. This is very useful in unat­tended applications where there may not be a designated system
operator to restart the system. If you choose to use the watchdog
timer, you can enable it under software control by using the infor­mation provided in Appendix B.

The watchdog counter is essentially a preset counter that counts
down based on the system’s real time clock. If the counter is not
reset before it times out (count = 0), it causes the power light to
blink and/or reboots the Tiger Cub based on the settings of J6 and
J8 jumpers.

With Without

Function Jumpers Jumpers

J6 Reboot on time out Yes No*
J8 Flash power LED on time out No Yes*

* Indicates factory default settings

The power light will continue to blink after the system reboots
even if the automatic reboot function is enabled.

When the J8 jumper is installed the light continues to blink so that
service personal will be alerted to the fact that the hang up oc­curred even though the automatic rebooting may prevent any
perceived interruption of service to the user. The blinking power
can be reset to the off state by turning the Tiger Cub power
switch off for at least 30 seconds.

The Tiger Cub has 3 LEDs and an external switch that may be
addressed by software utilities provided with the system.

The first LED (colored yellow) will turn on upon successful
completion of the BIOS Power On Self-Test (POST).

The second LED (colored green) will blink to indicate system
activity when the ITOXBLIN utility is run.

The third LED (colored red) is user-controllable and may be
turned on or off by using the routine ITOXLED provided in
ITOXLED.OBJ.

The Tiger Cub has a function known as console redirection which
allows the Tiger Cub to be controlled remotely via a serial link.

Appendix C

Frequently Asked Tiger Cub Questions

Q: I have MTEZ running on my notebook /desktop and I
can not control the Tiger Cub.

A: Make sure that the Console Redirection switch located on
the front panel over the GPIO LED’s is set to enabled (set to the
right). If console redirection is disabled, the yellow LED on the
GPIO LED display will not be illuminated. Set the switch to the
right and reset the Tiger Cub by turning the power off and on.

Q: When I try to run my program I see a flashing cursor in
the top right corner on my notebook /desktop.

A: If you have a flashing cursor most likely the program is
running. However, you must put the driver ITOXSCR.COM in
the AUTOEXEC.BAT file. This driver will create a video buffer
as if there was a video card in the Tiger Cub. If you install a video
card in the Tiger Cub you do not have to load ITOXSCR.COM.

Q: Can I configure the Tiger Cub, so that both a local
technician and a remote support specialist can see the
Tiger Cub’s console screen and control it from their key­board?

A: Yes. Run MTEZ (or another terminal emulation program) on
the local notebook/desktop computer and connect it to the Tiger
Cub using the console redirection mode. Run the host portion of
PC Anywhere (or an equivalent program) on the Tiger Cub and
run the remote part of PC Anywhere on the remote system which
is connected via modem. With such a configuration, both the

54

Frequently Asked Questions

local notebook and the remote PC can both see the virtual
display screen of the Tiger Cub and control it from their respec­tive keyboards. Note that the local user will only see text based
charters on his PC screen. Only one keyboard should be used at
a time since the key entries from each keyboard will go into a
common keyboard buffer.

Q: I installed a hard drive in my Tiger Cub and when I
start I get two options press (R) to reboot and (S) to enter
setup.

A: Even if the 1st boot device is set to C: drive you still need to
set the drive type in the CMOS setup. You can use drive type
48 if the drive is 528Megs or less and drive type 49 if the drive is
larger then 528Megs.

Q: I disabled certain tests in the Diagnostic program that
is built into CMOS. When I save and exit CMOS, and
then return to the Diagnostic program my changes are not
saved.

C

A: If changes have been made to disable certain test in CMOS,
those changes will only be for that diagnostic testing session. Any
changes will default back to enabled whether you save and exit
CMOS or not.

Appendix C

Q: I ran INTERSRV.EXE on my Tiger Cub and
INTERLNK.EXE on my notebook /desktop. After the
transfer of files was completed, I could not use my note­book /desktop to regain control of the Tiger Cub.
