OME-DB-16P Isolated Input Board
The OME-DB-16P is a 16-channel isolated digital input daughter board. The
optically isolated inputs of the OME-DB-16P consist of a bi-directional opto-coupler
with a resistor for current sensing. You can use the OME-DB-16P to sense DC signal
from TTL levels up to 24V or use the OME-DB-16P to sense a wide range of AC
signals. You can use this board to isolate the computer from large common-mode
voltage, ground loops and transient voltage spike that often occur in industrial
environments.

OME-DB-16R Relay Board
The OME-DB-16R, 16-channel relay output board, consists of 16 form C relays
for efficient switching of load by programmed control. The relays are energized by
applying 5 volt signal to the appropriated relay channel on the 20-pin flat connector.
There are 16 enunciator LEDs for each relay. They light when their associated relays
are activated. To avoid overloading your PC’s power supply, this board provides a
screw terminal for external power supply.

The OME-DB-24PR, 24-channel power relay output board, consists of 8 form C
and 16 form A electromechanical relays for efficient switching of load by
programmed control. The contact of each relay can control a 5A load at
250ACV/30VDCV. The relay is energized by applying a 5 volt signal to the
appropriate relay channel on the 20-pin flat cable connector (only uses 16 relays) or
50-pin flat cable connector.(compatible to the OME-DIO-24 series). Twenty four
enunciator LEDs (one for each relay) light when their associated relay is activated. To
avoid overloading your PC’s power supply, this board needs a +12VDC or +24VDC
external power supply.

I/O Control Register
3.1 How to Find the I/O Address
The plug & play BIOS will assign a proper I/O address to every OME-PCITMC12(A) card in the power-on stage. The IDs of OME-PCI-TMC12(A) are given
as following:
•
•
•
•
Vendor ID
= 10B5
Device ID
= 9050
Sub-vendor ID= 2129
Sub-device ID = 9912
We provide all necessary functions as following:
1. PTMC12_DriverInit(&wBoard)
This function can detect how many OME-PCI-TMC12(A) cards in the system.
It is implemented based on the PCI plug & play mechanism. It will find all
OME-PCI-TMC12(A) cards installed in this system & save all their resource
in the library.

3.2 The Assignment of I/O Address
The plug & play BIOS will assign the proper I/O address to OME-PCI-TMC12.
If there is only one OME-PCI-TMC12, the user can identify the board as card_0. If
there are two OME-PCI-TMC12 cards in the system, the user will be very difficult
to identify which board is card_0? The software driver can support 16 boards max.
Therefore the user can install 16 boards of OME-PCI-TMC12 in one PC system.
How to find the card_0 & card_1 ?
The simplest way to find the card number is to use DEM10.EXE given in
DOS demo program. This demo program will send a value to D/O and read back
from D/I. If the user installs a 20-pin flat cable between CON2 & CON3, the value
read from D/I will be the same as D/O. The operation steps are given as following:
1. Remove all 20-pin flat cable between CON2 and CON3
2. Install all OME-PCI-TMC12 cards into this PC system
3. Power-on and run DEM10.EXE
4. Now all D/I values will be different from the D/O values
5. Install a 20-pin flat cable into CON2 & CON3 of any OME-PCI-TMC12
card
6. There will be one card’s D/I value = D/O value, the card number is also
show in screen
Therefore the user can find the card number if he install a 20-pin flat cable into
OME-PCI-TMC12 sequentially.

3.3 The I/O Address Map
The I/O address of OME-PCI-TMC12(A) is automatically assigned by
the main board ROM BIOS. The I/O address can also be re-assigned by user.
It is strongly recommended to the user to not change the I/O address.
The plug & play BIOS will assign proper I/O address to each OME-PCITMC12(A). The hardware I/O ports are described as following:

3.4 New features of OME-PCITMC12A
3.4.1 Default Settings of OME-PCI-TMC12A
The default settings of J28 (when board is shipped) on OME-PCITMC12A(Sec. 3.4.4) makes it is equivalent to OME-PCI-TMC12. So the interrupt
system of OME-PCI-TMC12A in the default setting is compatible to OME-PCITMC12. Refer to Sec. 3.4.4 for interrupt block diagram of OME-PCI-TMC12 &
OME-PCI-TMC12A.
All Xor? of OME-PCI-TMC12A are clear to their Low states in the first
power-up stage, so all clock sources of OME-PCI-TMC12A are compatible to
those of OME-PCI-TMC12. Refer to Sec. 3.4.2 for block diagram.
As shipped the OME-PCI-TMC12A is used as an OME-PCI-TMC12. All old
application programs designed for OME-PCI-TMC12 can be executed
OME-PCI-TMC12A without any modification.

One new D/I port, wBase+0x18, for interrupt enable. The initial routine &
ISR must inport from wBase+0x18 to enable next interrupt operation. Refer to

source
z A Xor-control register is added to invert/non-inverted the selected clock
source. This mechanism can be used to generate 2 extra starting clocks to
8254.
Note: The Xor-control register is clear to 0 when the OME-PCI-TMC12A is
first power-up. So the initial state of OME-PCI-TMC12A is exactly compatible to
OME-PCI-TMC12.
Refer to Sec. 5.15 Ndemo2: Generate 2 Clocks, the twelve Xor-bits are used to
generate the 2 starting clocks. So the initial value of 8254 can be verified after these 2
starting clocks are generated. Then they are used to generate one single clock for
testing. In general, these Xor-bits are designed for generation of 2 starting clocks only.

z The Xor? is designed to generate the starting 2 clocks for 8254
z The XorInt is used to invert/non-invert the interrupt source to Low state, that is
to say, if the initial value of interrupt source is High, set this bit to High to
invert it to Low state. Refer to Sec. 5. 18 Ndemo5:Active Low Int for demo
program.
z When the TMC12A is first powered up, the initial values are all zero. So
Led1/2/3 are all turned ON. The Led1/2/3 are designed as status indicators. User
can use them based on their need.
Refer to Sec. 5.15 Ndemo2: Generate 2 Clocks, the twelve Xor-bits are used to
generate the 2 starting clocks. So the initial value of 8254 can be verified after these 2
starting clocks are generated. Then they are used to generate single clock for testing.
In general, these Xor-bits are designed for generation of 2 starting clocks only.

The interrupt mechanism of OME-PCI-TMC12 can be active Low or active High.
And the interrupt system of PCI bus is level trigger. So the Windows driver of OMEPCI-TMC12 must create a thread to handle all interrupt active conditions. There are so
many possible conditions and hence could affect the interrupt performance.
The new interrupt mechanism of OME-PCI-TMC12A is designed to improve the
performance of Windows driver as follows:
z initial subroutine & ISR will inport from wBase+0x18 to pre-set
int_signal_to_PC (Q in Sec. 3.4.4) to High state to enable the next interrupt
operation
z if the initial value of interrupt source is Low, set XorInt to 0 Æ rising-edge
interrupt
z if the initial value of interrupt source is High, set XorInt to 1 Æ falling-edge
interrupt
z the software driver is designed for rising-edge or falling-edge interrupt
When the interrupt ISR is executed, the int_signal_to_PC (Q in Sec. 3.4.4) is in
Low state, so the interrupt ISR must inport from wBase+0x18 to pre-set
int_signal_to_PC to High state to enable next interrupt operation. Refer to Sec. 5.16,

Demo2: Use D/I
If there is only one OME-PCI-TMC12, this program will test this only card.
If there are more than one OME-PCI-TMC12 cards installed in the PC system,
this program will test the second card.
How can you know which card is the second card? Please refer to Sec. 3.2 for
more information.

The CNT1 can be changed to CNT3/4/5/6.
The COUT of CNT 8/9/10/11/12/13 are
directly
connected
to
next
counter
without inverter. So they can not be used
to replace CNT1.
• The 12 CNTs of TMC-12 are divided into
two groups: inverted group & non-inverted
group. The inverted group includes CNT
1/2/3/4/5/6.
The
non-inverted
group
included CNT 7/8/9/10/11/12. The user has
to select his proper group for different
application.
