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.

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.
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.

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
Drivers are in each
corresponding folder

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:
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
dependent on its operation modes. Please refer to the following
