Quatech SDS User’s Manual Introduction Introduction Quatech’s line of Serial Device Servers (SDS) is designed to networkenable any device currently using RS-232 or RS-422/485 serial communications protocols. Our Device Servers provide industryleading hardware and user-friendly software to make connecting your serial devices to an Ethernet network a surprisingly simple process.
Introduction Quatech SDS User’s Manual Understanding how virtual communication ports work Note: Quatech Device Server technology now allows access to individual serial devices by anyone with access to the network on which they are installed. Note: Anyone in your organization with a PC can connect to the serial device over the network just as though the two devices were directly connected.
Quatech SDS User’s Manual Introduction Using Port numbers Note: You can think of the IP address as a telephone number and the port number as a telephone extension. Note: This information is useful for firewall configuration. In order for devices to communicate via a TCP connection or a UDP datagram, they must know each other’s IP address and port number. The SDS driver automatically sets the unit’s port number for you. A specific port number identifies each SDS serial port.
Introduction Quatech SDS User’s Manual IP address and TCP port number of the network host to which it should connect. If the SDS is idle, it will listen for normal Raw TCP mode connections from the network host. Raw UDP mode Note: Raw UDP can provide one-to-many communications. Raw UDP is used primarily for broadcasting messages over a network. It is lightweight and efficient; however, your application program must handle all error processing and retransmission.
Quatech SDS User’s Manual Introduction Features Note: Quatech Device Servers capture data from legacy serial devices without having to go through a PC. Quatech Device Servers can connect virtually any serial device to any standard Ethernet network (Intranet or Internet) using TCP/IP protocols.
Introduction Note: Traps are messages or alarms generated by an SNMP agent to indicate to the SNMP manager that a significant event has occurred. Quatech SDS User’s Manual information that a management network host can retrieve using the Get command. In addition to providing information upon request, the SDS supports a cold start Trap, which is a spontaneous message the SDS initiates whenever it boots up. WiFi implementation Note: WiFi is a wireless Ethernet communication option.
Quatech SDS User’s Manual Introduction Getting started Unpacking your SDS Follow these steps to unpack your SDS. Step Procedure Description Step 1 Remove the SDS from the box. Step 2 Remove all packing material from the SDS. Save the packaging in case you ever need to store the unit or return it to Quatech for service. Step 3 Check the contents of the package to make sure you have received everything listed below: ¾ SDS The complete SDS package ships in a single box.
Introduction Quatech SDS User’s Manual Identifying parts Figure 1 shows the connectors and indicator lights (LEDs) of the SDS. See below for a description of each item shown. Figure 1 – Connectors and Indicators The actual number and location of serial ports will vary according to the model.
Quatech SDS User’s Manual Introduction Understanding LED codes The SDS LEDs inform you of the communications status and activity of the SDS. The following table lists the possible states of the LEDs and their meaning.
Introduction Quatech SDS User’s Manual Locating serial and network ports Serial port(s) Note: The location of the serial port(s) varies, depending on the model. SDS serial ports connect via cables to your serial device(s). The number of these ports will vary depending on the SDS model. All SDS models come with DB-9 serial port connectors. RS-232 “M” models include adapter plugs to convert the DB-9 connectors to RJ-45 connectors.
Quatech SDS User’s Manual Introduction Figure 3 - RJ-45 pinouts (DB-9 to RJ-45 adapter) Figure 4 and Tables 5 and 6 show the RS-232/422/485 -RJ-45 pinouts and signal descriptions. Table 5 - RS-232 signals on RJ-45 connector (DB-9 to RJ-45 adapter) Note: If your serial port cable uses an 8-pin RJ-45 plug, you can use the center eight pins of the SDS’ RJ-45 connector for RS-232 communications. You will lose access to the Ring Indicator signal.
Introduction Quatech SDS User’s Manual Network port All SDS devices have one eight-pin RJ-45 Ethernet port on the back panel. Figure 4 - RJ-45 Ethernet port pinout Figure 5 and Table 7 show the Ethernet RJ-45 pinouts and signal descriptions.
Quatech SDS User’s Manual Making connections Making connections Figure 6 shows a four-port SDS connected to a printer.
