1.1 Introduction
The MIC-3620 is a 3U-sized 8-port High Speed RS-232 PCI Comm.
CompactPCI™ and serial communication card, which complies with PICMG
2.0 R2.1 CompactPCI specifications. The MIC-3620 requires only one CPCI
slot within the computer and provides independent serial channels. All channels
are addressed in a continuous 32 byte I/O block for simplified software access.
It is possible for all channels to share one PCI interrupt. An interrupt status
register is available for determining the interrupt source.
The MIC-3620 comes standard with 16C954 UARTs containing an optional 128
byte FIFOs. These upgraded FIFOs greatly reduce CPU overhead and are an
ideal choice for heavy multitasking environments.

This chapter gives users a package item checklist, proper instructions about
unpacking and step-by-step procedures for card installation.
2.1 Initial Inspection
In addition to this manual, you should find the following items inside the
shipping package of the MIC-3620:
• CPCI communication interface card MIC-3620
• Advantech Automation Software CD-ROM
• CPCI communication card user's manual
•Wiring cable
Prior shipping, we have carefully inspected the CPCI communication card
series. It should be free of marks and scratches and in perfect working order on
receipt. As you unpack the CPCI communication card series, check for signs of
shipping damage (damaged box, scratches, dents, etc.). If it is damaged or fails
to meet specifications, immediately notify our service department or your local
sales representative. Please also notify the carrier. Retain the shipping carton
and packing materials for inspection by the carrier. Once inspected, we will
make arrangements to repair or replace the unit.
When you handling the CPCI communication card series, remove its protective
packaging by grasping the rear metal panel. Keep the anti-vibration packaging.
Whenever you remove the card from the PC, store it in this package for
protection.
Note:
Discharge your body’s static electric charge by touching the back of the grounded
chassis of the system unit (metal) before handling the board. You should avoid contact
with materials that hold a static charge such as plastic, vinyl and styrofoam. Handle the
board only by its edges to avoid static damage to its integrated circuits. Avoid touching
the exposed circuit connectors. We also recommend that you use a grounded wrist
strap and place the card on a static dissipative mat whenever you work with it.

2.2 Hardware Installation
Note
Make sure you have installed the driver first before you install the card (please refer to
the software installation details in Chapter 3 Driver Setup & Installation).
Once you have doubled check that the DLL driver of the MIC-3620 installation is
complete, you can proceed with the MIC-3620 card installation in your CPCI
computer. Once in doubt, please consult with your computer’s user manual or
related documentation. Please follow the following steps to install the card on
your system.
To install a card:
Step 1: Remove one cover on the unused slot of your CPCI computer slot.
Step 2: Hold the Card Vertically. Be sure that the card is pointing in the correct
direction. The components of the card should be pointing to the right-hand side
and the black handle of the card should be pointing to the lower edge of the
chassis.
Step 3: Hold the lower handle and pull the handle down to unlock it.
Step 4:Insert the MIC-3620 card into the CPCI chassis carefully by sliding the lower
edges of the card into the card guides.
Step 5: Gently push the card into the slot by sliding the card along the card guide until
J1 meetsthe long needle on the backplane.
Note
If your card is correctly positioned and has slid all the way into the chassis, the handle
should match the rectangular holes. If not, remove the card from the card guide and
repeat step 3 again. Do not try to install a card by forcing it into the chassis.
Step 6: Push the card into the right place, secure the card by pushing the handle to lock
it into place.
Note 1
Advantech MIC-3612’s “Hot-Swap”function complies with CPCI Hot Swap
Specification PICMG 2.1 R2.0.
Note 2
Because the card holds “Hot-Swap”, Blue LED on the front plane indicates the status of
the card installation when the system is on. Instep 5, Blue LED will turn on when J1
meets the long needle on the backplane;In step 6, the system will automatically
configure the card,the Blue LED will turn off when the system completes the device
configuration.
If system’s power is turned off, you can install the card step by step without considering
the Blue LED’s state.

8
To remove a card:
Step 1:Push the handle down to unlock the card, and the CPCI system will
automatically uninstall the card configuration.
Step 2: Once the system finishesthe device configuration, the Blue LED on front
plane will turn on. Now you can slide the card out.
Note
Because the card holds“Hot-Swap”, the above steps will removethe card process
when the system is on. If the system power is off, please do step1 and step2 without
attending Blue LED’s state.

4.1 Register Structure
This appendix gives short descriptions of each of the module's registers. For more
information please refer to the data book for the OX16C954 UART chip.
All registers are one byte. Bit 0 is the least significant bit, and bit 7 is the most
significant bit. The address of each register is specified as an offset from the port
base address (BASE).
DLAB is the "Divisor Latch Access Bit”, bit 7 of BASE+3.
BASE+0 Receiver buffer register when DLAB=0 and the operation is a read.
BASE+0 Transmitter holding register when DLAB=0 and the operation is a write.
BASE+0 Divisor latch bits 0 -7 when DLAB=1.
BASE+1 Divisor latch bits 8 -15 when DLAB=1
The two bytes BASE+0 and BASE+1 together form a 16-bit number, the divisor,
which determines the baud rate together with the values of TCR and CPR and Bit7
of MCR (Modem Control Register) (refer to 16C954 datasheet). The formula to
set BaudRate as follows:
In formula, SC is sample clock value defined by TCR, when TCR=0x00, SC =16.
Prescaler is defined by MCR[7] and CPR.
Prescaler = 1 when MCR[7] = ‘0’;
Prescaler = M+(N / 8), when MCR[7] =‘1’,
where: M = CPR[7:3] (Integer part –1 to 31)
N = CPR[2:0] (Fractional part – 0.000 to 0.875 )
While Bit7 of MCR is Logic”1”, TCR=0x00 and CPR=0x40, set the divisor as
follows:
Baudrate Divisor Baudrate Divisor
50 2304 3600 32
75 1536 4800 24
150 768 7200 16
300 384 9600 12
600 192 19200 6
1200 96 38400 3
1800 64 57600 2
2400 48 115200 1
Table 4-1

Else, while Bit7 of MCR is Logic”0”, TCR=0x00, set the divisor as follows:
Baudrate Divisor
230400 4
307200 3
460800 2
921600 1
Table 4-2
BASE+1 Interrupt Enable Register (IER) when DLAB=0
Bit0 Enable received-data-available interrupt
Bit1 Enable transmitter-holding-register-empty interrupt
