Note: If any of these items are missing or damaged, please contact your distributor or sales representative immediately.
MOS-1120/MOS-1121 was carefully inspected mechanically and electrically before it was shipped. It should be
free of marks and scratches and in perfect working order when received.
As you unpack the MOS Module, check for signs of shipping damage (damaged box, scratches, dents, etc.). If it is
damaged or it fails to meet specifications, notify our service department or your local sales representative immediately. Also
notify the carrier. Retain the shipping carton and packing material for inspection by the carrier.
After inspection we will make arrangements to repair or replace the unit. When you handle the MOS Module, remove
it from its protective packaging by grasping the rear metal panel. Keep the anti-vibration packing. Whenever you remove
the card from the PC, store it in this package for protection.

3. Driver Setup & Installation
Installation
Discharge your body’s static electric charge by touching the back of the grounded chassis of the system unit
(metal) before handling the board. You should avoid contact with materials that hold a static charge such as
plastic, vinyl and Styrofoam. Handle the board only by its edges to avoid static damage to its integrated circuits.
Avoid touching the exposed circuit connectors.We also recommend that you use a grounded wrist strap and place
the card on a static dissipative mat whenever you work with it.

6.1 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 for 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 PC’s, terminals and some printers. DCE refers to the device being communicated with or controlled.
Examples include modems, DSU’s (digital service units), printers and lab/factory equipment.
In some situations you may be able to get by with just three lines: data on TXD, a signal ground and a handshaking
line. Examples are printer or plotter connections, troubleshooting and situations where you require only one-wire
communication.
Table 6.1 Terminal or PC (DTE) Connections
6. Wiring
MOS-1120/MOS-1121 User Manual 7

Table 6.2: Modem Connections
For DTE to DCE connections, use a 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 6.3: Terminal without Handshake
Therefore, if you are not using CTS, RTS, DSR,DTR and DCD signals, short pins 4 and 5 together, and please short
pins 6, 8,and 20 together.
6.2 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 6.4:RS-422 DB9 Pin Assignment
Terminator Resistors Setup
The signals DSR, DTR and DCD are shorted internally on the PCM-24D2R4/24D4R4 cards when operating in
RS-422 mode. A user can solder in termination resistors if necessary for impedance matching. The card has two
mounting spaces for termination resistors, but no resistors are installed at the factory. Each pair of signal lines has a
separate resistor (RxD+/-, TxD+/-).
MOS-1120/MOS-1121 User Manual 8

6.3 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 PCM-24D2R4/24D4R4
cards automatically sense the direction of the data flow and switch the transmission direction —no handshaking is
necessary. This means a user can build an RS-485 network with just two wires. This RS-485 control is completely
transparent to the user. The software written for half duplex RS-232 works without any modification.
Termination Resistor Setup
You can install termination resistors if necessary for impedance matching. The card has mounting spaces for
termination resistors, but no resistors are installed at the factory. Depending on your application you may need to
solder in a single resistor to handle the DATA+/DATA- pair (and a corresponding resistor on the other end of the
connection). The value of the resistor should equal the characteristic impedance of the signal wires (approximately
120 Ohms or 300 Ohms).
