TSD1 Datasheet (131k/PDF documents require Adobe Acrobat Reader pdf)


The TSD1 is a self contained device designed to decode and transmit barcoded data to a central computer using the ComputerWise TNET "REAL TIME" shop floor data collection system.

The TSD1 can be used for:

  • Door entry access control
  • Time and Attendance recording
  • Event Tracking
  • Machine control
  • Security alarm system
  • Remote data entry

Bar-code Interface

The bar-code interface connects to the integral barcode card reader on the standard TSD-1; or a hand-held wand scanner or other wand emulating device. The bar code interface will auto-discriminately interpret/decode barcode symbols printed in several popular barcode symbologies (including Code 39, Code 128, Interleave 2 of 5, UPC/EAN, and CODABAR). The TSD1 can support one or two wand-emulating barcode readers.

Communications Port

The communications port serves as the interface between the TSD1 and the TNET network. The port transmits data scanned by the operator to the host computer (through the TNET) and receives commands from the host (through the TNET) to control the internal LEDs and relays. Data is transmitted in a serial asynchronous format, at a selected baud rate and parity using the TNET protocol (RJ45 modular jack).

LED Indicators

The red and green LED indicators provide operator feedback. These LEDs independently turn on, turn off, flash or pulse when the TSD1 receives specific ESCape sequences from the host. These LEDs are also used to indicate the unit is in the Setup Mode.

Optional Relays

The two optional relays provide operator feedback. These relays will independently turn on, turn off or pulse when the TSD1 receives specific ESCape sequences from the host computer. A Relay can be used to open a door, turn on a machine, etc.


The optional magnetic stripe card reader interface connects to a track 1 or track 2(ABA), or dual track MSCR reader. The interface can optionally output the start and stop codes.

Optional Proximity Card Reader (RFID)

The optional RFID proximity card reader configures the TSD1 to read proximity cards.

Proximity card component


J1 - Power Adapter port. Provides power to units not being powered by TNET. The DC-10 jack connects to a DV-1250/06 12VDC 500 ma power adapter.

J2 - Serial Communications port (RJ-45 jack). Connects to TLD2 and TIM1B TNET devices (RS-422). Connects to the PC during setup (RS-232 using TMA3 cable adapter).

J3 - Barcode port(s). Connects to a wand emulating barcode reader. Two barcode ports interface via a six position square post header. The standard port #1 uses pins 1-3. The optional port #2 uses pins 4-6.
