1 Product Overview 1.1 Functional Overview The RuggedVDSLTM RS910L is an industrial hardened serial server and managed Ethernet switch supporting Ethernet over VDSL (EoVDSL). The RS910L can be configured with 2 serial ports (RS485/RS422/RS232/fiber) and/or 2 Ethernet ports (copper or fiber). The RS910L can interconnect multiple types of intelligent electronic devices (IEDs) that have different methods of communications.

2 Installation 2.1 Din Rail Mounting An optional DIN rail mounting bracket is available for the RS910L. The figure below details mounting instructions for the standard 1” DIN Rail. Figure 3 - RS910L DIN Rail Mounting 8 2007 RuggedCom Inc.
2.2 Power Supply Wiring and Grounding 2.2.1 AC Power Supply Wiring and Grounding Figure 4 - RS910L Power Supply Inputs The RS910L AC power supply inputs should be connected as follows: 1. +/L should be connected to AC Line/Hot. 2. -/N should be connected to AC Neutral. 3. Surge Ground should be connected to the Chassis Ground via a braided cable or other appropriate grounding wire. Surge Ground is used as the ground conductor for all surge and transient suppression circuitry internal to the unit. 4.
2.2.2 DC Power Supply Wiring and Grounding Figure 5 - DC Power supply wiring and grounding diagram The RS910L low voltage DC power supply features reverse polarity protection and dual independent inputs. The latter feature allows the connection of two DC sources with the same nominal voltage to provide redundant power supply inputs. The RS910L DC power supply inputs should be connected as follows: 1. Connect to the DC inputs according to the polarity markings on the unit. 2.
2.2.3 Dielectric Strength Testing Units which are to have dielectric strength testing (HIPOT testing) done in the field must have the braided ground cable disconnected during the test. This is required in order to prevent the surge suppression circuitry, which is connected to surge ground, from being activated. Figure 6 - Dielectric Strength Testing 11 2007 RuggedCom Inc.
2.3 Failsafe Output Wiring The Failsafe output relay is provided to signal critical error conditions that may occur on the RS910L. The contacts are energized upon power up of the unit and remain energized until an alarm condition or power loss occurs. The behavior of the failsafe relay is configurable via the RuggedSwitch Operating System. Consult the RuggedSwitch Users Guide for details. Figure 7 - RS910L Failsafe Output Relay 12 2007 RuggedCom Inc.
2.4 RS232 Console Port Wiring The RS232 port is used for configuring the RS910L. A straight-through serial cable with a DB-9 connector is required. There is no need to crossover the TxD and RxD signals from the PC side since this has been done internally as is shown in the figure below.
3 Serial Ports The RS910L can be equipped with a Fiber Serial Interface, RS232/RS485/RS422 DB9 serial ports or RS232/RS485/RS422 RJ45 serial ports. 3.1.1 Fiber Serial Interface The RS910L can be equipped with a Fiber Serial Interface (ST connector only) which allows RS485, RS422, or RS232 devices to communicate over secure, noise immune, optically isolated, fiber optic cabling at extended distances as well as protocol independent conversion to multimode fiber optics.

Figure 12: Conceptual recommended RS485 wiring diagram 3.1.5 Serial Port Transient Protection RuggedCom does not recommend the use of copper cabling of any length for critical real-time substation automation applications. However, transient suppression circuitry is present on all copper ports to protect against damage from electrical transients and to ensure IEC 61850-3 and IEEE 1613 Class 1 conformance.
4 Ethernet Ports 4.1 RJ11 Ethernet over VDSL Port 4.1.1 Overview The Ethernet over VDSL (EoVDSL) port on RS910L operates in pairs with one configured as the Master and the other as the Slave. In VDSL literature the terms Central Office (CO) or Line Termination (LT) are used interchangeably for the Master and the terms Customer Premise Equipment (CPE) or Network Termination (NT) are used interchangeably for the Slave. Configuration of Master or Slave mode is done through the RuggedSwitch Operating System.
4.1.2 Wiring VDSL typically operates over 2-wire CAT-3 wiring; however, other categorized or uncategorized twisted-pair wiring will work although the performance will vary depending on the distance and cable characteristics. It is important that the wiring used does not have any open leads (also known as bridged taps or drop-lines) along its length because this will impact performance by degrading the signal. 4.1.3 Configuration & Setup 1. Log into the RuggedSwitch Operating System. 2.
The unit can automatically select the best bit-rate based on current line conditions. If the line conditions degrade (reducing the SNR) but the unit is able to maintain the link, an alarm will be triggered to notify the user of the reduced SNR. If the line conditions degrade such that the unit is unable to maintain the current link, the unit will restart the scan process. NOTES: 1.
Table 5 - RJ45 Ethernet port pin-out NOTE: RuggedCom does not recommend the use of CAT-5 (10/100Base-TX communications) cabling of any length for critical real-time substation automation applications. However, transient suppression circuitry is present on all copper ports to protect against damage from electrical transients and to ensure IEC 61850-3 and IEEE 1613 Class 1 conformance. This means that during the transient event communications errors or interruptions may occur but recovery is automatic.
