Section 5 - Hardware Installation Installing and Mounting the USR60x USR60x converters come supplied with DIN rail mounting clips and panel mount adapters. Figure 6: DIN Rail Mounting Clip The DIN rail mounting clip is attached to the back of the unit using three machine screws (included). This mount enables the unit to be clipped directly to a standard DIN rail. Figure 7: USR602 with Panel Mount Adapters Panel mount adapters are attached to the unit with three machine screws on each side.
Section 5 - Hardware Installation • External power via pluggable terminal strip - 10 to 48 VDC, 16 watts max • External power via locking power jack - 10 to 48 VDC, 16 watts max Figure 8: Power Supply Connections When the unit is USB powered the current available to the converter may be limited by the USB host. If the converter is connected to an external USB hub the maximum available current may be insufficient to operate the converter. In that case an external power supply should be connected.
Section 5 - Hardware Installation Connecting to the Serial Ports The USR602 provides two serial ports; the USR604 has four. DB-9M connectors are used for RS-232, RS-422 and RS-485 two-wire and four-wire connections. Figure 10: DB-9M Serial Port Connectors The following illustration shows the pin numbering of the DB-9M connector. Figure 11: DB-9F Pin Numbering The following table shows the wiring pin-outs for RS-232, RS-422 and RS-485 two-wire and four-wire connections.
Section 5 - Hardware Installation Termination and Biasing USR60x converters include internal biasing resistors on the RS-422/RS485 interfaces. The values for internal biasing resistors are: Biasing: 1k ohms (default IN PLACE when in RS-422/485 modes) The biasing resistors are connected to the receive lines, pulling the RDA(-) line to ground and the RDB(+) line to a positive voltage. The bias resistor is automatically IN when you select RS-422/485 mode.
Section 5 - Hardware Installation • Switches 5 and 6 configure Port 3 • Switches 7 and 8 configure Port 4. Figure 133: USR604 DIP Switch and Power Connectors Operating modes are RS-232, RS-485 two-wire half-duplex, RS-485 four-wire full-duplex, and RS-422.
Section 5 - Hardware Installation LED Indicators USR602 converters include five LED indicators; USR604 converters include nine LED indicators. In both models one indicates the presence of power; the others indicate transmit and receive data present on each port.
Section 6 - Advanced User Settings SECTION 6 Advanced User Settings 5 In This Section Setting Serial Port Properties ...................................... Advanced Settings in Device Manager ......................... Modbus Basics .......................................................... . Serial port parameters and other advanced settings are configured on the USB Isolated Serial Port Properties and Advanced Settings windows, which are accessible via the Device Manager.

The Advanced Settings dialog appears. Figure 188: Advanced Settings Configure the advanced settings as required (refer to the following sections for details) and click OK to store the settings. COM Port Number When installing the drivers the first available COM port number is assigned to the first COM port on the USR60x device.
Section 6 - Advanced User Settings Select lower settings to correct performance problems at low baud rates. Select higher settings for faster performance. BM Options The BM Options dropdown list provides a setting for the Latency Timer. The latency timer is a form of time-out mechanism that counts from the last time data was sent from the USR60x back to the PC. If the latency timer expires, the USR60x will send any data it has available to the PC. It then resets and begins counting again.
Section 6 - Advanced User Settings Event On Surprise Removal - The Event On Surprise Removal option is generally left unselected. Set RTS On Close - Selecting the Set RTS On Close option will set the RTS signal on closing the port. Disable Modem Ctrl At Startup - This option is used to control the modem control signals DTR and RTS at startup. Devices that monitor these signals can enter the wrong state after an unplug-replug cycle on USB. Page 29 of 45 Document Number: USR60x-0812m www.bb-elec.com/ www.
Section 6 - Advanced User Settings Modbus Basics Modbus is an industrial data communications protocol that emerged in the mid-1970s and continues to be widely used in current industrial systems. Originally designed to link terminals with Modicon PLCs, it is simple, easy to learn and implement, and free to use. It quickly became a defacto standard in the industry and has been widely implemented with successful results.
