Overview

The ET315 Ethernet Terminal improves upon the ET205 by offering higher-speed Ethernet capability at a lower cost. The ET315 is a data collection device that communicates with a software application program over a TCP/IP network. The operator interface consists of an alphanumeric display and a membrane keypad with additional input options available. This unit is available with optional 802.11b/g wireless connectivity.

Theory of Operation

The ET315 connects to a 10/100BaseT Ethernet network and functions similar to a Telnet terminal. The host software can send commands and displayable messages to the terminal via the network. User input from the keypad, optional barcode, or mag-stripe reader is sent to the host software. To minimize network traffic the user input is transferred as complete strings instead of character by character. Strings are terminated by the Enter key and terminated with the ASCII <CR> <LF> characters. The barcode and mag-stripe input automatically include the Enter function.

Terminal Emulation

ET315 terminals operate in two modes: the Virtual Terminal Command (VTC) mode and the ANSI terminal mode. The VTC mode provides a unique but simple protocol that eliminates the need to know all the particulars of the lower level ANSI protocol. The ANSI emulation mode is a subset of the standard ANSI terminal protocol that supports most of the standard display manipulation command set. The included DCNET application program (Win9x/NT based) adds ready-made Ethernet data collection capability.

Network Interface

Connecting to an Ethernet LAN is via a standard 10/100BaseT cable. From a network perspective, it occupies a single socket at a specified TCP/IP address and port number. The host software communicates with the ET315 by establishing a connection with the terminal and then sending and receiving ASCII text command strings.

Operator Interface

The ET315 includes an LCD display and a numeric keypad as the primary operator interface console. In, addition, the ET315 terminal may include an optional barcode scanner input, mag-stripe card reader input, or RFID reader input and an aux RS-232 port for connection of a serial input device. Optional digital inputs with counters (up to 4) and software controlled relay outputs (up to 4) provide machine control for an external device.

Display

The ET315 display uses a two (2) line by twenty four (24) column LCD character display which displays the 96 standard ASCII characters and 96 non-standard symbols in a 5 x 7 dot matrix font. Cursor position is identified by a blinking box and can be positioned under software control. Backlighting is available as an option for low light installations.

Input / Output options

Several input/output options are available as follows:

Barcode Input
The barcode decoder input option allows one or two barcode devices to be attached on the ET315 terminal. Decoded input is treated just like keyboard entered data and can be configured to include an automatic Enter (<CR>) code. The ET315 will automatically discriminate and decode Code 39, Code 128, Interleave 2/5, Codabar, and UPC/EAN symbologies. Available input devices include wands, slot readers, and wand emulating CCD or laser scanners. The Wall Mount version of the ET315 can be supplied with an integral slot reader as one of the bar-code input devices.

Mag-Stripe Input
The mag-stripe decoder input option allows either a single or dual track magnetic card reader to be attached. Either single Track #1 or Track #2 reader can be decoded and the input is treated just like keyboard entered data. If a dual track reader is installed Track #1 will be decoded first and if it fails Track #2 will be decoded.

Relay Output
The ET315 can be supplied with either two (dual) or four (quad) output relays that can be individually activated under software control. Each relay has a single "form A" contact rated at 10va (100vdc, 100ma.) maximum. Access to the contacts is via screw terminal blocks on the back of the unit.

Power Supply

Power for the ET315 comes from a 12vdc (6va rating) power adapter that plugs directly into a standard 120vac receptacle (a universal power supply is available for other voltages). Typical power consumption is less than 10 watts. Optional input devices (laser scanners, card readers, etc.) can increase the power consumption slightly. Alternate power supplies can be used by connecting them via the ET315 power jack.
