Card, serial communication cards which complies with PICMG 2.0 R2.1 CompactPCI specifications. All channels are addressed in a continuous 32 byte I/O block for simplified software access. All channels may also share one PCI interrupt. The MIC-3612 comes standard with 16C850 UARTs containing 128 byte FIFOs. These upgraded FIFOs greatly reduce CPU overhead and are an ideal choice for heavy multitasking environments. 1.2 Features PCI Specification 2.1x compliant Speeds up to 921.6 Kbps 16C850 UARTs with 128-byte standard Standard Industrial 3U/6U sized CPCI Board size I/O address automatically assigned by PCI Plug-and-Play OS supported: Windows@98/2000/XP/7, Linux Surge protection (2500VDC).

It should be free of marks and scratches and in perfect working order on receipt. As you unpack the CPCI communication card series, check it for signs of shipping damage (damaged box, scratches, dents, etc.). If it is damaged or it fails to meet specifications, notify our service department or your local sales representative immediately. Also notify the carrier. Retain the shipping carton and packing material for inspection by the carrier. After inspection we will make arrangements to repair or replace the unit. When you handle the CPCI communication card series, remove it from 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. MIC-3612/3-BE User Manual 4 Chapter 2 Hardware Configuration 2.2 Hardware Installation Note! Make sure you have installed the driver first before installing the card (Please refer to the software installation in Chapter 3 Driver Setup & Installation). When you install the MIC-3612 Card, be sure the DLL driver of the MIC-3612 installation is complete, you can now go on to install the MIC-3612 card in your CPCI computer. But it is suggested that you should refer to the computer user manual or related documentation if you have any doubt. Please follow the steps below to install the card on your system. To install a card: 1. Remove one cover on the unused slot of your CPCI computer slot. 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 lower edge of the chassis. 3. Holding the lower handle, pull the handle down to unlock it. 4. Insert the MIC-3612 card into the CPCI chassis carefully by sliding the lower edges of the card into the card guides. 5. Please push the card into slot gently by sliding the card along the card guide until CN1 meets the long needle on the backplane. Note! If your card is correctly positioned and has been 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. 6. Push the card into the right place; secure the card by pushing the handle on to lock it into place. Note! The Blue LED on the front panel details the installation status of the card while the system is on. In step 5, when CN1 meets the long needle on the backplane, Blue LED will light; after step 6, the system can configure the card automatically, and the Blue LED is turned off when the system finished the device configuration. If the system power is off, you can install the card step by step without attending Blue LED's state. 5 MIC-3612/3-BE User Manual To remove a card: 1. Push the handle down to unlock the card, then the CPCI system will automati- cally uninstall the card configuration. 2. Once the system finished the device configuration, the Blue LED on the front panel will turn on. Now you can slide the card out. Note! Advantech MIC-3612's "Hot-Swap"function complies with CPCI Hot Swap Specification PICMG 2.1 R2.0. Note! Because of the "Hot-Swap", the above steps detail the card removal process while the system is on. If the system power is off, please follow step1 and step2 and disregard the status of the Blue LED. 2.3 I/O Address In this section, you will learn to set an I/O base address for the MIC-3612. Base address setting When the MIC-3612 is installed in the system or if the machine is first turned on, the configuration software must scan the various buses in the system. If the software locates the MIC-3612, the system will configure the device based on the parameters of the PCI device configuration registers, including the I/O base address, I/O range, memory base address, memory range, and so forth. The I/O base address is the base address on the four ports of the MIC-3612 card. The four ports address are as shown: Base Address Setting CH 1 Base Add. + 00H CH 2 Base Add. + 08H CH 3 Base Add. + 10H CH 4 Base Add. + 18H MIC-3612/3-BE User Manual 6 Chapter 2 Hardware Configuration 2.4 Board Layout: Dimensions Figure 2.1 MIC-3612 board layout: Dimensions 2.5 Jumper Setting This section provides the card default configuration and the options for setting each jumper. 2.5.1 How to set jumpers You configure your card to match the needs of your application by setting the jumpers. A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To "close" a jumper you connect the pins with the clip. To "open" a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2 and 3. In this case you would connect either pins 1 and 2 or 2 and 3. You may find a pair of needle-nose pliers for setting the jumpers. If you have any doubts about the best hardware configuration for your application, contact your local distributor or sales representative before you make any changes. Figure 2.2 Jumper setting example 7 MIC-3612/3-BE User Manual 2.5.2 Default Settings The board is shipped with default settings (all ports are set to RS-422 mode without any terminator resistors). If you need to change these settings, however, see the following sections. Otherwise, you can simply install the card. For MIC-3612, each port can support three operation modes, RS-232, RS-485 and RS-422. RS-232 mode For RS-232 operation mode, set the jumper group CN4(CN5,CN6,CN7) for Port 1 (2,3,4) to the RS-232 available position. RS-485 mode For RS-485 operation mode, users will have to use the following list to set the jumpers. 1. Jumper group CN4(CN5,CN6,CN7) for Port 1 (2,3,4) to the RS-422/485. 2. Jumper JP10(JP11,JP12,JP13)for Port 1(2,3,4) to the RS-485. 3. DIP switch SW1 have to switch to "AUTO" for RS-485 mode ON OFF CH1 ON AUTO CH2 ON AUTO CH3 ON AUTO CH4 ON AUTO MIC-3612/3-BE User Manual 8 Chapter 2 Hardware Configuration RS-422 Master mode For RS-422 Master mode, the RS-422 Tx signal will always be enabled. For this mode, users will have to use the following list to set the jumpers. 1. Jumper group CN4(CN5,CN6,CN7) for Port 1 (2,3,4) to the RS-422/485. 2. Jumper JP10(JP11,JP12,JP13) for Port 1(2,3,4) to the RS-422. 3. For RS-422 Master mode, DIP switch SW1 will have to be "ON" ON OFF CH1 ON AUTO CH2 ON AUTO CH3 ON AUTO CH4 ON AUTO RS-422 Slave mode For RS-422 Slave mode, the RS-422 Tx signal will be auto-enabled to send the data. To set this mode, users will have to use the following list to set the jumpers. 1. Jumper group CN4(CN5,CN6,CN7) for Port 1 (2,3,4) to the RS-422/485. 2. Jumper JP10(JP11,JP12,JP13) for Port 1(2,3,4) to the RS-422. 9 MIC-3612/3-BE User Manual 3. For RS-422 Slave mode, DIP switch SW1 will have to be switched to "AUTO" ON OFF CH1 ON AUTO CH2 ON AUTO CH3 ON AUTO CH4 ON AUTO 2.5.3 Terminator resistor setup (JP2~JP9) In the RS485/422 mode, you can install terminator resistors to match line impedance. For each signal line Tx (Data), Rx will have to be a separate resistor 120 or 300. For more details about jumper locations please refer to Figure 2-1 2.5.4 66MHZ_ENABLE pin Setup The 66MHZ_ENABLE pin indicates to a device whether the bus segment is operating at 66 or 33 MHz. However, MIC-3612 can only operate at 33MHz limited by FPGA model. By default, the jumper CN2 is closed, that indicates bus segments are limited to 33MHz.
