Section 2 - VESP211 Hardware Vlinx VESR4x4 Serial Server SECTION 2 VESP211 Hardware VESP211 Serial Servers are enclosed in a rugged panel mountable enclosure and feature:  LED indicators  Power, Ethernet and serial connectors  A recessed Reset (mode) switch.
PAGE 10
Section 2 - VESP211 Hardware Vlinx VESR4x4 Serial Server LED Indicators VESP211s have three LED indicators: a Ready LED, an Ethernet LED, and a Serial LED. Figure 3. Front Panel of the VESP211 Ready LED The Ready LED (green) blinks once per second if the system is operating correctly. If the LED is off, it indicates the system is not operating correctly (or that it is in Console Mode). Ethernet LED The Ethernet LED illuminates if the Ethernet port is connected when data is transmitted or received.
PAGE 11
Section 2 - VESP211 Hardware Note: Vlinx VESR4x4 Serial Server LEDs on the serial server are also used to indicate various Reset modes, as described in the following section. Reset Switch A recessed momentary Reset switch is located on the side of the enclosure. To activate the switch, insert a small plastic tool through the hole in the enclosure and press lightly. Figure 4.
PAGE 12
Section 2 - VESP211 Hardware Vlinx VESR4x4 Serial Server Using the Reset Switch to exit Console Mode Press and hold the Reset switch for two seconds, or remove power from the serial server, wait a few seconds, and turn the power on again. The LEDs go back to their normal states when the device resumes normal operation. Using the Reset Switch to Reload Factory Default Settings Hold the Reset switch for more than ten seconds.

Section 2 - VESP211 Hardware  Vlinx VESR4x4 Serial Server VESP211-485 serial servers use five-position removable terminal blocks for RS-422 and RS-485 connections. Figure 6. Five-Position Pluggable Terminal Blocks Note: Refer to Appendix D for connection pin-outs. Power Connector VESP211 serial servers use a barrel jack connector for power. The connector accepts a 2.1 millimeter plug and requires 12 VDC at 2.5 W maximum. Figure 7.

Section 3 - Initial Setup and Connections Vlinx VESR4x4 Serial Server SECTION 3 Initial Setup and Connections This section describes how to setup and connect VESP211 Serial Servers. Note: In this section devices to be connected to the serial server’s serial connection are simply referred to as the “serial device”. Connecting the Power Supply Connect a DC power supply by plugging a 12 VDC power source into the barrel jack on the top of the serial server. The center connection must be positive (+).
PAGE 16
Section 3 - Initial Setup and Connections Vlinx VESR4x4 Serial Server RS-485 The RS-485 interface supports 2-wire or 4-wire operation. When configured for 4-wire operation the connection supports two signal pairs: TDA (-), TDB (+), RDA (-), RDB (+) and GND. This makes full-duplex operation possible. The data lines are differential pairs (A & B) in which the B line is positive relative to the A line in the idle (mark) state. Ground provides a common mode reference.

Section 3 - Initial Setup and Connections Vlinx VESR4x4 Serial Server Figure 12. Direct IP and Virtual COM Port Connection In Virtual COM Port Mode a PC can communicate across the network to the serial server as if the serial ports on the serial server are the PC’s serial ports. When a virtual COM port is configured on the PC (using Vlinx Manager) a new COM port appears in the Device Manager. Windows programs using standard Windows API calls are able to interface to virtual COM ports.
