Moxa Technologies TCF-141-S Manuale utente

If you use DB9 for an RS-485/422 cable connection, the Pin

definition and assignments are as follows:

• RESISTOR SW

(Terminal Resistor/Pull-up and Pull-Down Res. Setting)

You may configure RESISTOR SW for proper termination or

P-UP, P-DOWN resistors for the network connection.

Fig. 2: DB9 to Fiber Converter Side Panels

The RESISTOR SW is used for RS-485/422 protocol/connection,

and takes effect when STANDARD CONFIG is at "485/422".

2. Switch Settings

The two side panels of the Converter contain a total of four sets

of DIP Switches (abbreviated SW)—labeled RS485 WIRING,

DB9 CONFIG, STANDARD CONFIG, and RESISTOR—that

are used to configure the various data transmission modes. The

proper configuration of each of these four sets of DIP Switches

is described below:

RESISTOR SW default: 1, 2, 3, 4. All are at "OFF"

RX-TERM ON: Enables 130Ωterminator on RX

TX-TERM ON: Enables 130Ωterminator on TX

P-DOWN ON: Enables 1 KΩpull down on

RS422 TXor

RS485(2-wire)TX/RX-

• STANDARD CONFIG

For selecting serial port protocol: RS-232 or RS-485/422.

P-UP ON : Enables 1 KΩpull up on

RS422 TX+ or

RS485(2-wire)TX/RX+

RS232: RS-232 protocol/connection, default.

485/422: RS-485/422 protocol/connection.

• RS485 WIRING

Note:

For selecting between 2-wire and 4-wire RS-485.

The way in which the termination and P-UP, P-DOWN resistors

are set up depends on the RS-485/422 network configuration.

2wire: 2-wire at half-duplex mode.

4wire: 4-wire at full-duplex mode, default.

• DB9 CONFIG

• Ensure that the copper cable and its voltage polarity match

the device requirements for a 4-wire or 2-wire connection.

232: RS-232/DB9 connection, default.

485/422: RS-485/422 via DB9 port

• Improper termination and network configuration will cause

the devices to work poorly.

NOTE: The STANDARD CONFIG and DB9 CONFIG DIP

Switch settings must agree. Either set both to RS-232, or set

both to RS-485/422.

3. LED Description

• When thee Rx-TERM & TX-TERM switches are enabled,

both P-Down & P-Up DIP switches should be on as well.

For DB9 model and port connection, the available

connections by the three SW settings are:
