Although RS-232 serial ports are found on almost every computer, because of their slow transmission speeds, limited range, and limited networking capabilities, they are not an effective solution for industrial strength long distance communications systems.

Systems based on the RS-485 standard, however, utilize different voltage lines for the data and control signals, so they are not subject to the RS-232 limitations.

The IC-485S / IC-485SI is a bidirectional converter that transparently converts RS-232 signals to RS-485 signals (and vice versa). The IC-485S / IC-485SI provides Point-to-Point; Multidrop; and Simplex operations over distances of up to 1200 m (4000 ft.), thus permitting the creation of reliable long distance data communications systems using standard computer hardware.

The IC-485S / IC-485SI's operating mode parameters are set with two slide switches:

◆ SW1 sets the Device Mode
◆ SW2 sets the Transmitting and Receiving Mode

Terminology

Explanations of the SW! and SW2 terms are given in the table below:

Term Explanation
DCE Data Communications Equipment; if the IC-485S / IC-485SI is going to be plugged into a DTE device, the IC-485S / IC-485SI must be set to DCE.
DTE Data Terminating Equipment; if the IC-485S / IC-485SI is going to be plugged into a DCE device,, the IC-485S / IC-485SI must be set to DTE.
TxON,, RxON This setting is used in Point-to-Point operations,, in which the unit is always in Transmitting and Receiving Mode.
TxRTS, RxRTS This setting is used in Multidrop operations, in which the unit is in Transmitting Mode when the RTS signal is high, and is in Receiving Mode when the RTS signal is low.
TxRTS, RxON This setting is used in Multidrop Full Duplex operations to monitor the RS-485 line signals. Receiving Mode is always ON. Transmitting mode only occurs when the RTS signal is high.

The IC-485S / IC-485SI supports four operating modes: Point-to-Point; Multidrop; Simplex; and Monitor (IC-485S only). Point-to-Point and Multidrop can be configured for Full or Half Duplex. Each of the operating modes is explained in the sections that follow.

Point-to-Point

A Point-to-Point configuration is one in which two devices, located at two different places are linked for communication by a pair of IC-485S or IC-485SI units. There are two configurations: Point-to-Point Full Duplex, and Point-to-Point Half Duplex.

1. Point-to-Point Full Duplex

- Point-to-Point Full Duplex uses reverse four wire cabling as shown in the diagram below:

graph LR A["DB-25 DB-25"] --> B["T+"] A --> C["T-"] A --> D["R-"] A --> E["R+"] B --> F["R+"] C --> G["R-"] D --> H["T-"] E --> I["T+"] J["Connect to PC#1's COM port"] <--> K["DB-25 DB-25"] L["Connect to PC#2's COM port"] --> M["DB-25 DB-25"]

For both IC-485S / IC-485SI units, set SW1 to DCE or DTE depending on what type of device the IC-485S / IC-485SI will plug into (if it will plug into a DCE device, configure it for DTE, and vice versa).
For both IC-485S / IC-485SI units, set SW2 to TxON, RxON.

2. Point-to-Point 2 Wire Half Duplex

- Point-to-Point Half Duplex uses straight through four wire cabling, as shown in the diagram below:

graph LR A["DB-25 DB-25"] -->|Connect to PC#1's COM port| B["T+"] A -->|Connect to PC#1's COM port| C["T-"] A -->|Connect to PC#1's COM port| D["R-"] A -->|Connect to PC#1's COM port| E["R+"] F["DB-25 DB-25"] -->|R+| G["T+"] F -->|R-| H["T-"] F -->|R+| I["T+"] J["DB-25 DB-25"] --> K["Connect to PC#2…

For both IC-485S / IC-485SI units, set SW1 to DCE or DTE depending on what type of device the IC-485S / IC-485SI will plug into (if it will plug into a DCE device, configure it for DTE, and vice versa).
For both IC-485S / IC-485SI units, set SW2 to TxRTS, RxRTS.

Note: The RTS signal is controlled by an external software command. The IC-485S / IC-485SI has no capability to control this signal by itself

Multidrop

A Multidrop configuration is one in which more than two devices are linked for communication using several IC-485S / IC-485SI units.

One of the devices that one of the IC-485S / IC-485SIs connects to is designated as the Primary device. All the remaining devices that the rest of the IC-485S / IC-485SIs connect to are designated as Secondary devices. There are two configurations: Multidrop Full Duplex, and Multidrop Half Duplex.

1. Multidrop 4 Wire Full Duplex

- Multidrop Full Duplex uses reverse four wire cabling to link all the connected IC-485S / IC-485SI units:

graph TD A["PC1"] --> B["Primary"] C["COM1/COM2"] <-- B B --> D["Secondary 1"] D --> E["PC2"] D --> F["COM1/COM2"] B --> G["Secondary 2"] G --> H["PC3"] G --> I["COM1/COM2"] G --> J["..."] G --> K["Secondary 31"]

For all IC-485S / IC-485SI units, set SW1 to DCE or DTE depending on what type of device the IC-485S / IC-485SI will plug into (if it will plug into a DCE device, configure it for DTE, and vice versa).
For the Primary unit, set SW2 to TxON, RxON.
For all Secondary units, set SW2 to TxRTS, RxON.

2. Multidrop Half Duplex

- Multidrop Half Duplex uses straight-through four wire cabling, to link all the connected IC-485S / IC-485SI units:

For all IC-485S / IC-485SI units, set SW1 to DCE or DTE depending on what type of device the IC-485S / IC-485SI will plug into (if it will plug into a DCE device, configure it for DTE, and vice versa).
For all IC-485S / IC-485SI units set SW2 to TxRTS, RxRTS.

Note: The RTS signal is controlled by an external software command. The IC-485S / IC-485SI has no capability to control this signal by itself.

Simplex

A Simplex configuration is one in which more than two devices are linked for communication using several IC-485S / IC-485SI units in a manner similar to Multidrop. The difference is that in a Simplex configuration, the Primary device can only talk, and the Secondary devices can only listen.

- Simplex uses reverse two wire cabling to link all the connected IC-485S / IC-485SI units, as shown in the figure below:

$graph TD A["PC1\nCOM1/\nCOM2"] <--> B["Primary"] B --> C["Secondary 1"] C --> D["PC2"] C --> E["PC3"] C --> F["PC4"] B --> G["Secondary 2"] G --> H["PC3"] G --> I["PC4"] B --> J["Secondary 3"] J --> K["PC3"] J --> L["PC4"] B --> M["..."] B --> N["Secondary 31"]$

For all IC-485S / IC-485SI units, set SW1 to DCE or DTE depending on what type of device the IC-485S / IC-485SI will plug into (if it will plug into a DCE device, configure it for DTE, and vice versa).
- For all of the units (Primary and Secondary), set SW2 to TxON, RxON.

Monitor IIX-485S Only!

With Monitor Mode, the RS-485S can be wired to the lines of an RS-485 or RS-422 device to monitor the line signals. In this configuration, the RS-485S changes the functions of T+ and T- to R'+ and R'- respectively.

graph TD A["Device 1"] -->|T+| B["Device 2"] A -->|R-| B A -->|R+| B C["IC-485S"] -->|T+ (R'+)| D["PC"] C -->|T- (R'-)| D C -->|R-| D C -->|R+| D D --> E["PC → COM1/COM2"]

Set SW1 to Monitor.
Set SW2 to TxRTS, RxON

Note: 1. The RTS must be Low in Monitor Mode.

The R+ and R- signals are converted and linked to the RS-232 port, DB-25 pin 3. The R'+ and R'-(T+ and T-) signals are converted and linked to the RS-232 port, DB-25 pin 2.
Set each IC-485S / IC-485SI's configuration switches according to the information provided in the Switch Configuration and Operating Modes sections.
Plug the IC-485S / IC-485SI's DB-25 female connector into the computer's RS-232C port.
Connect the IC-485S / IC-485SI units to each other:
Use two or four wire twisted pair cable in a reverse or straight through configuration according to the information provided in the Switch Configuration and Operating Modes sections.
For the IC-485S, you may use either the RJ-11 telephone socket, or wire directly to the Terminal Block (See the Terminal Block section for pin assignment details).
For the IC-485SI, you must ground the device by connecting a grounding wire from the Grounding Tab to the grounding source.

Note: 1. When tightening the terminal connector screws it is recommended to use a Phillips PH1 Screwdriver.

Over-tightening the terminal connector screws may result in damage to your IC-485S or IC-485SI and difficulty loosening the screws.
Power on the computers. The units are now ready for operation.

The Terminal Block

The four screw terminal block has different pin assignments depending on the operating mode:

In DCE/DTE mode, terminals 1 (+V) and 2 (-V) are configured to transmit data (the transmitter); while terminals 3 (-V) and 4 (+V) are configured to receive data (the receiver).
In Monitor mode (IC-485S only), terminals 1 and 2 are, respectively, the positive and negative of receiver 1; while terminals 3 and 4 are, respectively, the positive and negative of receiver 2.

Pin DCE/DTE Monitor
1 Transmitter +V Receiver 1 +V
2 Transmitter -V Receiver 1 -V
3 Receiver -V Receiver 2 -V
4 Receiver +V Receiver 2 +V

DCE / DTE Connection Table

Because of the polarity of the communication signals, a DTE configured device must connect to a DCE configured device. The shaded area in the figure below is an example of a DTE to DCE connection:
