1. S1_PWR, S2_PWR: Pin-9 Power Setting Jumpers for S1, S2 Respectively: The

design of each DB9 male connector has an option to supply DC power to

its Pin-9. Pin number 9 of the DB9 connector was defined for RS232 RI (Ring

Indicator) signal. Since some applications do NOT use this signal, in that

case, Pin-9 can be used to deliver DC power for the serial devices. This

product provides 2 settings for the power, +5V and +12V. The default

factory setting was set at “RI”, i.e. no power supplied on the DB9M

connector’s pin-9.

2. Mode DIP Switch Settings –S1_MODE, S2_MODE:

There are two 8-pin DIP switches S1_MODE and S2_MODE for the settings of

serial Port S1 and Port S2 respectively. It is used for changing the operating

modes, enable/disable terminator and enable/disable the bias for transmitter

and receiver signals.

⚫Mode Settings:

Each DIP switch has 8 pins, the first 3 pins (M0, M1, M2) are for mode settings

(RS232, RS485-2wire, RS485-4wire or RS422 modes), pin 4 (TERM) is to enable or

disable terminator. Pin 5 and 6 (T+, T-) is for biasing TX+ and TX- signals. Pin 7

and 8 (R+, R-) is to enable or disable bias for RX+ and RX- signals.

2S RS232/422/485 3-in-1 Serial PCIe Card

Note: Pin 4 to 8 are designed for RS422 and RS485 only and

should be set to OFF when you are setting the port to RS232 mode.

resistors for TX+, TX-, RX+, RX- signals respectively. Please note that you have to

set them to OFF if you are setting the port to RS232 mode.

1. To install the Windows drivers, there are two methods, one is to

run the setup utility (StnSetup.exe) in each corresponding folder.

The other one is by the Windows’driver installation Wizard. We

recommend you run the setup utility. It will be simpler. However,

PLEASE REFRESH HARDWARE OR REBOOT THE SYSTEM IN CASE

YOUR DRIVER DID NOT TAKE EFFECT AFTER RUNNING THE SETUP

UTILITY.

The drivers are shipped in the following folders on the driver CD:

E:\IO\MOSCHIP\MCS99xx

In some cases, you may want to uninstall the drivers. To remove the

drivers that already installed for Windows, there are two methods:

1. Run (double click) the uninstall program (for example

MOSCHIP_StnUninst.exe) in each Windows’folder on the

supplied driver CD, it is usually in the same folder as the

StnSetup.exe utility:

Drivers are in each

corresponding folder

2. Go to Windows’Control Panel’s Add/Remove Program to

remove the drivers.

The pin assignment of the DB9 male connector of the Module Box is
