installing the driver
thanks to windows 95/98’s plug and play capability, you can easily plug the smartio cp-168u board into an available pci slot, and then get to work right away with very little installation effort. windows 95/98 will automatically detect the presence of the new board, and prompt you to install the software driver. you simply need to have the driver cd available to complete the installation process.
a maximum of 4 smartio cp-168u boards can be installed in one system, provided sufficient i/o address and irq number resources are available.
the following flow chart illustrates the driver installation stages of the smartio cp-168u boards. each stage will be discussed later in more detail.
first time driver installation
this stage gives the steps for installing the smartio cp-168u board driver for the first time. the installation of the smartio cp-168u board for windows 95 and windows 98 are slightly different and will be described in two columns. follow the steps in the left column for windows 95 or the right column for windows 98.
if one moxa cp-168u board was previously installed and another moxa cp-168u board is plugged in, the system will prompt you to skip this stage, and take care of port configuration, which is discussed in the next section.
1. upon detecting the first new smartio cp-168u series board, windows 95/98 will automatically display a new hardware found message box, and then display the following dialog boxes. click the next button to proceed.
2. click on [other locations].
3. type e:\software\win9x\v5.7\windows.95 in the location input box, and then click [ok] from the select other location window. the system will start reading the files from the cd.
4. click on [finish].
1. upon detecting the first new smartio cp-168u series board, windows 95/98 will automatically display a new hardware found message box, and then display the following dialog boxes. click the next button to proceed.
2. select [display a list...] and then click on [next].
3. select other devices and then click on [next].
4. click on [have disk].
5. type e:\software\win9x\v5.7\windows.95 and click [ok]. the system will start reading the files from the cd.
6. click on [next].
7. click on [next].
port configuration
after the driver is installed, the moxa cp-168u installation dialog box will be displayed, and the system will map the ports automatically.
if one moxa cp-168u board was installed previously, and another moxa cp-168u board is added, the system will prompt you to take care of port configuration, which is discussed in this section.
1. click on a specific port from the the cp-168u series installation window, and then click on [port setting] to open the port x dialog box.
2. select a com number for the port from the port number pull-down list.
3. check the auto enumerating com number check-box to have subsequent ports mapped to continuous com numbers. for example, if com 3 is assigned to port 1, then com 4 will be automatically assigned to port 2.
4. select an rx fifo trigger from the rx fifo trigger pull-down list. rx fifo trigger levels from 1 to 62 bytes are available, with a default value of 56 bytes. check set the change to all ports check-box to apply the just defined rx fifo trigger to all ports.
5. select a tx fifo size from the tx fifo size pull-down list. tx fifo sizes from 1 to 64 bytes are available, with a default value of 64 bytes. check set the change to all ports check-box to apply the just defined tx fifo size to all ports.
6. click [ok] in the port x dialog box to confirm the port settings, and then click [ok] in the property dialog box to complete the port settings.
board and port ready
board and port ready for windows 95 and windows 98 are slightly different. in finishing this stage, the driver installation will be complete.
windows 95
after the port configuration, you can immediately use the com ports of the smartio cp-168u board without restarting windows 95.
windows 98
after the port configuration, click on [finish]. the com ports of the smartio cp-168u board can be used without restarting windows 98.
if an error message similar to “cp-168u board(busno=x, devno=x, port1=comx) interrupt number is invalid!” pops up, refer to the “troubleshooting” chapter for solutions.
if you want to add more boards after installing the driver, simply plug the additional smartio cp-168u board into an empty pci slot, and windows 95/98 will automatically detect the newly plugged board. skip to port configuration to take care of port settings.
this completes the installation of the smartio cp-168u board driver, including board and port configuration. however, if you need to make changes to the board and port configuration, refer to the next section, “configuring board and port,” for configuration details.
once the board and the driver are installed and the driver restarts successfully, you can start to develop applications with the pcomm library (see “serial programming tools”) or the microsoft win32 api. you can also use applications such as terminal emulator (see “serial programming tools”), a pcomm utility, or hyperterminal, to transmit/receive data, as well as remote access service to provide dial-up networking capabilities.
configuring the board and ports
follow the procedures given below to re-configure the com number for the ports of installed boards and drivers under windows 95/98.
in addition to following the procedures listed below, you may also click on [start] → [programs] → [moxa utility] → [moxa smartio/industio configuration panel] → [property] → [port setting].
since this is a pci board, once a new board is added, or an existing board is removed, the board’s configuration will be automatically added or removed by the operating system when you restart the pc.
1. open the [control panel], click on the [system] icon, select the [device manager] tab, and then click on the plus sign to the left of moxa smartio/industio multiport board.
2. click on the desired cp-168u board, and then click on [properties].
3. select the [ports configuration] tab, click on the specific port, and then click on the [port setting] button.
4. check the auto enumerating com name check-box to assign continuous com numbers for subsequent ports. for example, if com3 is assigned to port 1, then com4 will be automatically assigned to port 2.
5. re-assign the rx fifo trigger by selecting a number from the pull-down list. check the set the change to all ports check-box to apply this setting to all ports. rx fifo trigger levels from 1 to 62 bytes are available, with a default value of 56 bytes.
6. re-assign the tx fifo size by selecting a number from the pull-down list. check the set the change to all ports check-box to apply this setting to all ports. tx fifo sizes from 1 to 64 bytes are available, with a default value of 64 bytes.
7. to complete the update, click [ok] in the port x dialog box, click [ok] in the cp-168u board properties dialog box, and then click [ok] on the device manager tab.
8. restart the system to activate the latest configuration.
updating the driver
this section shows how to update the windows 95/98 driver.
1. open [control panel], click on the [system] icon, and select the [device manager] tab.

5. click on [have disk...] and type the path of the new driver.
6. insert the driver cd into the cd-rom drive, and then click [ok] in the install from disk window.
7. the system will automatically prompt you to restart the system. click [yes] to restart the system, or [no] if you want to reboot the system later.
removing the driver
this section explains how to remove the smartio cp-168u board driver.
1. open the [control panel], double click the [add/remove programs] icon, and then select the [install/uninstall] tab.
2. click on the moxa smartio/industio driver option and then click on [add/remove] to start the driver removal process.
