1 1 1 Introduction Overview The Standard Multiport Async Solutions The standard C168P multiport boards offer 8 serial ports for connecting terminals, modems, printers, data acquisition equipment and any other serial devices to the PC/AT and its compatible systems. The Smartio C168P is equipped with custom-designed ASIC chip which replaces lots of conventional ICs and reduces the board to half-size. The whole family supports 16 bit architecture. Full range of I/O addresses and IRQs are available

RS-485 Mode The Opt8J supports only 2-wire RS-485 communication. Set the respective switch to ON position to use RS-485 interface. This means the port can transmit data only when RTS is asserted, and receive data only when RTS is not asserted (half-duplex). Refer to Chapter “Connection Option (Opt8x) and Cable Wiring” for RS-422/RS- 485 cable wiring. And also to Chapter “Serial Programming Tools” for Opt8J RS- 485 programming details.

2 2 2 Hardware Installation The installation of the C168P consists of hardware and software installation. The hardware installation is detailed in this chapter. The next chapter deals with the software installation for various operating systems. JP1 C168P Default Settings The C168P has the following default (factory) settings: I/O address: 0x180 (Port 1), 0x188 (Port 2), 0x190 (Port 3), 0x198 (Port 4) 0x1A0 (Port 5), 0x1A8 (Port 6), 0x1B0 (Port 7), 0x1B8 (Port 8) IRQ: 10 INT Vector: 0x1C0 CAP J

Now you should do either the normal hardware installation (detailed in the later section, “Hardware Installation with IO-IRQ Utility”) or the quick hardware installation (detailed right in the next section, “Quick Hardware Installation”). The latter is provided to facilitate the hardware installation, only under the circumstances that: υ Only one C168P board is allowed to install in a system. υ Windows NT and 95/98 are the only operating systems supported. υ I/O address 0xA700 must be free Q

Hardware Installation 5. DO power OFF and then ON (or Reset) the PC. (Please cold start.) 6. Restart System (Windows NT/95/98). It is very important to keep the JP1 always short in this case. Without running the hardware configuration program, Io-irq.exe under DOS prompt, the software configuration program will automatically update the hardware settings of the board while updating the software settings. This saves the trouble doing hardware configuration. However, remember to cold start the syst

1. Choose a PC that has DOS system inside. 2. Power off the PC. 3. Make sure no hardware conflict and plug the board in a free 16-bit slot of the PC, one board at a time with JP1 open. + If you are installing multiple boards, insert one board at a time and configure it using the Io-irq program before inserting the next board. This is to prevent conflict between two boards with same default hardware settings. The C168P has the following default (factory) settings, I/O address: 0x180 (Port 1),
