TDL2A Evaluation KitWith onboard RS232 driver, serial port and antenna connector TDL2A Evaluation Kit enables user to evaluate transparent data link capability of TDL2A OEM modems. The eval kit is also u seful for range testing and it enables evaluation of TDL2A for various antenna types, areas of w eak coverage (inc null spots), packet errors etc. • RS232 driver and DB9F connector for direct interface to PC serial port • Setup is simple as Plug-and-Play • Set-up and configuration using HyperTerminal • Access to internal diagnostic/Test modes using HyperTerminal • On board SMA antenna connector • Signal LED for visual indication of valid code received • RF Remote Control Demonstration • Size: 73 x 70 x 17mm (excluding helical antenna length of 50mm) The Eval kit feature an on board MAX232 RS232 driver, 9 way D connector, 5V voltage regulator, SMA RF connector and helical antenna, hence requires just a Voltage supply to power up and operate a TDL2A without any additional interface circuitry. The snap off feature of the PP3 battery holder reduces the board size by half (73 x 33 x 17mm) and allows external power supply connection. Kit Contents The TDL2A Evaluation Kit is supplied with the following contents: 2 TDL Evaluation Board 2 TDL2A modules (ordered separately) 2 1/4-wavelength monopole or helical antennas (ordered separately) Additional requirements 1. DB9M - DB9F straight through serial cable 2. External power supply or DC power adaptor (optional) 3. PC/PDA with terminal program (e.g. Hilgraeve HyperTerminal) TDL2A Eval Kit - Short Technical Overview Page 1

In order to use all the functions embedded in the on board TDL2A modem, the user must be aware of the setup /programming facility, which allow different addresses and frequency channels to be set up, and if necessary accesses diagnostic test modes. The TDL2A is programmed through the same RS232 port that is used for sending/receiving data. An RS232 terminal emulator (such as Aterm or HyperTerminal) is an ideal tool. Connect the TDL2A eval kit directly (or via serial straight through cable) to the PC serial port. To enter program mode, insert the PGM jumper (to pull the SETUP pin of TDL2A low)...

Figure 2: Schematic diagram of TDL2A Eval Kit Figure 3: PCB layout of TDL2A Eval Kit On-board regulator (L4931) can supply up to 250mA current at 5V. R9 (LK1) connects pin 9 (Ring Indicator) on the D type to the 5V, which enables any external host to be powered from pin 9 (+5V DC) and pin 5 (GND). Certain CCD barcode scanner can make use of this feature, eliminating the need for additional external power adaptor. R8 connects STATUS (data ready, via an RS232 buffer) to DCD, DSR and CTS. Not linking this jumper (LK2 at the back of the board) saves power. LEDs are provided for visual indication...
