CHAPTER 1 2 Introduction This chapter introduces the PCL series and their specifications.
Chapter 1 Introduction 1.1 Description The ISA cards of the PCL Series provide an independent processor 16C550, 16C554 or 16C654 UART with an on-chip 16-byte or 64-byte FIFO buffer for reliable high-speed serial I/O. The UART buffers data into 16-byte or 64-byte packets before putting it on the bus. This drastically reduces the CPU’s load and avoids data loss when the system is busy and can’t process the interrupt quickly, which is especially useful for high speed serial I/O under Windows.

2.3 Jumper Settings This section tells how to set the jumpers to configure your card. It gives the card default configuration and your options for each jumper. 2.3.1 How to Set Jumpers You configure your card to match the needs of your application by setting 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.
2.3.3 Default Setting The board is shipped with default settings. If you need to change these settings, however, see the following sections. Otherwise, you can simply install the card. Note that you will need to disable your CPU card's onboard COM ports, if any, or set them to alternate addresses / IRQ. Table 2.1: Default setting of ISA Comm.
Figure 2.11: Mode Selections for PCL-741 Note: When RS-232, RS-422 or RS-485 mode is selected, current-loop Tx/Rx active/passive jumpers are inoperable. Should you want to configure the PCL-740 or PCL-741 to operate in the current loop mode, configure the main jumper for current-loop. You also have to set Tx and Rx for active or passive mode. In the active mode the Tx or Rx will generate the current required for data transfer over the link.
Figure 2.13: Current Loop Link PCL-743B/S, PCL-745B/S, PCL-846A/B You can set each port individually for either RS-422 (the default) or RS485 operation. The figure below shows the jumper settings. Figure 2.14: RS-422/485 Mode Selection for PCL-743B/S, PCL-745B/S and PCL-846A/B Enable Mode Selection Jumpers set the driver enable mode selections of every port respectively. If a jumper is set to "AUTO," the driver automatically senses the direction of the data flow and switches the direction of transmission.
If a jumper is set to "ON," the driver is always enabled, and always in high or low status. The user must select a mode before beginning RS-422 applications. Figure 2.15: Enable Mode Selection for PCL-743B/S, PCL-745B/S and PCL-846A/B PCL-746+ Should you wish to configure the PCL-746+ to operate in the RS-232 mode, then the upper two pins of the 12*3 pin jumper should be connected. For RS-422/ RS-485 mode selection, the bottom two pins of the 12*3 pin jumper should be connected as shown below. Figure 2.
Figure 2.17: Mode selection for PCL-746+ 2.3.5 I/O Address and Interrupt Setup Next, you will need to select an IRQ (interrupt request) number, and an I/ O base address for the Card. In PCL-746+, PCL-846A/B and PCL-849A/ B/+, you can choose standard mode or enhanced mode. For other cards such as PCL-740, PCL-741, PCL-743B/S, PCL-745B/S, PCL-849L and PCL-858A/B, the cards are designed for enhanced mode.
Figure 2.19: Standard or Enhanced Mode selection for PCL-846A/B Figure 2.20: Standard or Enhanced Mode selection for PCL-849A/B/+ Standard Mode In this mode each of the four ports can be setup as the address or the IRQ channel individually. Port Base Address 1 3F8 2 2F8 3 3E8 4 2E8 Enhanced Mode In this mode all four ports share the same IRQ and continue to use the cards designated IRQ address.
Base address setting (SW1 or S2) For base address specify the I/O address of the first port and subsequent ports are set continuous base addresses by the offset of 8 bytes. For instance, if the first port is set for 300H, then the second port is set to 308H sequentially. For 8 ports, specify the continuous PORT number of the first port and subsequent ports are mapped to continuous PORT numbers.
The following example shows how to set the base address to 2F8. The switch sum is set to 2F8: 200 + 80 + 40 + 20 + 10 + 8 (HEX). Figure 2.22: Setting to 2F8 Note: On the PCL-740, PCL-741, PCL-743B/S, PCL745B/S, PCL-846, PCL-849A/B/+/L address line A9 does not appear on the DIP switch, as it is permanently hardwired to hex 200. Interrupt Level (IRQ) Setting In PCL-746+, PCL-846A/B and PCL-849A/B/+, you can choose shared IRQ or Independent IRQ.
Figure 2.23: Shared or Independent IRQ selection for PCL-746+ Figure 2.24: Shared or Independent IRQ selection for S2 of PCL-746+ and S1 of PCL-849A/B/+ Independent IRQ Mode In this mode, each of the four ports can have IRQ channels set individually. For each port, select an IRQ, which is not already in use by another card in the system. The mapping of jumpers to ports is as shown below.
Shared IRQ Mode In this mode, all channels in card share the same interrupt (IRQ), and interrupt status register is available for determining the interrupt source. Select an IRQ, which is not already in use by another card in the system. If you are installing more than one card, set them to different IRQ number. Jumper Bank JP1 controls the card IRQ. Simply place the jumper on the interrupt level as shown in the following figure. You can set share IRQ selection as the following table shows. Figure 2.
2.3.7 Interrupt Status Register Bit Function 0 Port 1 1 Port 2 2 Port 3 3 Port 4 4 Port 5 5 Port 6 6 Port 7 7 Port 8 You may change the interrupt status address via SW2 or S5. Please note the address decoder will occupy a continuous, 8-byte area related to switch setting. For example, if you set the switch to 210H, the addresses 210H to 217H will all be decoded. The various DIP switch settings (SW2 or S5) for the interrupt status register are shown in the figure below. Figure 2.
2.3.8 Speed Mode selection PCL-735B/S, PCL-745B/S, PCL-746+, PCL-846A/B and PCL-858A/B employ a unique speed option that allows the user to choose either normal speed mode (1x) or high speed mode (8x). The high speed mode is selected with SW2. Normal Speed Mode To select the baud rate commonly associated with COM ports, such as 2400, 4800, 9600 bps, or 115.2 kbps, place the switch as follows. High Speed Mode To increase normal mode rates up to eight times, (e.g. if 115.

5.2 Wiring 5.2.1 RS-232 Signal Wiring Since the RS-232 interface is not strictly defined, many devices have their own connection methods, which may ignore some signal lines or define reserved lines for other functions. It is best to refer to the user’s manual of your device for installation instructions. You may find the following helpful. In general, DTE (Data Terminal Equipment) refers to the device that is leading the communication. Examples include PCs, terminals and some printers.
For DTE to DCE connections, use straight through cable (i.e., you don't have to reverse lines 2 and 3, lines 4 and 5, and lines 6 and 20 since, in general, the DCE RS-232 interfaces are reversed themselves). Table 5.
5.2.2 RS-422 Signal Wiring The RS-422 interface wiring is based on one-to-one principles. The transmit lines on one side connect to the receive lines on the other side, and vice versa. With RS-422, you can transmit and receive data simultaneously (full duplex). The connections are as follows: Table 5.
5.2.3 RS-485 Signal Wiring The RS-485 standard supports half-duplex communication. This means that just two wires are needed to both transmit and receive data. Handshaking signals (such as RTS, Request To Send) are normally used to control the direction of the data flow and to switch the transmission accordingly. In RS-485 mode, the communication card automatically senses the direction of the data flow and switches the transmission direction — no handshaking is necessary.
