Palm Sens User Guide Chapter 4

Appendix 5 Installing or updating Pocket PC software Place the Pocket PC in the cradle connected to the PC. The PC will show a window with the title ‘Microsoft ActiveSync’. As soon as the Pocket PC is connected as indicated in the ActiveSync window the software can be installed or updated. Before the software can be updated, the programs PalmScan and PalmTime must be closed. They can not be replaced with new versions when they running on the Pocket PC. Run the setup program on the PalmSens CD-ROM using the auto run menu. If this menu doesn’t appear when you insert the CD-ROM, you should run the setup program by selecting ‘Run’ from the ‘Start menu’ and clicking the ‘Browse’ button. The PalmScan and PalmTime setup program is located on the PalmSens CD-ROM in ‘\PSPPC\Setup.exe‘. If you have downloaded an update from the internet, look for the location of where you have extracted the setup files from the downloaded package. After running ‘Setup.exe’ the message appears: Choose Yes The message appears: Choose Yes again After installation is complete, the Pocket PC shows the message “Palm Instruments, B.V. Holland PalmSens is already installed. Reinstall?” Choose OK and if necessary, choose to overwrite existing files. Note: In case the message ‘Failed to copy file’ is given, two files have to be deleted from the disk of the PC: C:\Program Files\PalmSens\PalmSens.Arm……CAB C:\Program Files\PalmSens\PalmSens.INI These files are created during the initialization process and may be ‘write protected’. Therefore the second time that the software is installed, the program can not make a copy again. Appendix 6 CH8 eight channel multiplexer The multiplexer CH8 is used with PalmSens if a sensor-array is used. The multiplexer is supported by the PalmScan as well as PalmTime program. The presence of the multiplexer is specified in the windows ‘Instrument’ → ‘Settings’. The channel is selected in the window ‘Instrument’ → ‘Control’. CH8 is connected to the sensor connector of PalmSens. The miniDIN cable has to be connected to the connector at the left-hand side of the instrument. This miniDIN cable is used to power the multiplexer and to control the channel-selection. In case the multiplexer is controlled from user-made software, refer to the example control program, called ‘PSControl’, available from Palm Instruments. The multiplexer can be used in different modes. Each mode is set by a number of jumpers. On the board of the instrument there are seven jumpers marked by J1 … J7. The jumpers are: J1: J2: J3: J4: J5: J6: J7: Is placed when the sensor has a combined reference and counter electrode. This jumper connects therefore RE to CE. If the sensor array has more than one working electrode, but one counter and/or reference electrode, this jumper is placed. CE from PalmSens is connected directly to pin 1 and pin 19 of the 36-pin connector If the sensor array has more than one working electrode, but one counter and/or reference, this jumper is placed. RE from PalmSens is connected directly to pin 7 and pin 25 of the 36-pin connector This jumper is placed if CE has to be multiplexed. This is the case when each of the sensors has its own counter electrode. This jumper is placed if RE has to be multiplexed. This is the case when each of the sensors has its own reference electrode. Is placed if all unselected working electrodes or sensors have to remain polarized at the potential as set by PalmSens. If this jumper is not placed only the selected channel is polarized. This option is not available in all devices. This jumper is effective only if IC13 and IC14, next to the jumper are placed.) For future use. Is left open normally. In order to change the configuration, follow the next steps: - be aware of static electricity and use an anti-static wrist band if possible or connect yourself to safety ground and work on a anti-static bench mat disconnect CH8 from PalmSens remove the black caps from the screw holes using a needle or something similar (be careful) remove the four screws remove the two screws of the high density connector remove the upper part of the housing by levering it with a small screwdriver from the side remove the PCB from the housing configure the instrument by means of the jumpers place the PCB back in the housing fasten the screws of the high density connector fasten the four screws of the side panels Location of the jumpers. Some common configurations are: - Sensor array with up to eight working, eight reference and eight counter electrodes: o Jumpers placed are: J4 and J5 - Sensor array with up to eight working and eight combined reference/counter electrodes: o Jumpers placed are: J4, J5 and J1 Note: the reference/counter electrodes are connected to either the reference or counter electrode leads. - Sensor array with up to eight working electrodes all sharing one reference and one counter electrode: o Jumpers placed are: J2 and J3 Note: the reference and counter electrodes are connected to RE direct and CE direct (see CH8 cable description) respectively. - Sensor array with up to eight working electrodes all sharing one combined reference/counter electrode: o Jumpers placed are: J2, J3 and J1 Note: the reference/counter electrode is connected to either RE direct or CE direct (see CH8 cable description). The pins of the high density centronics connector on the CH8 module are: Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Pin 6 Pin 7 Pin 8 Pin 9 Pin 10 Pin 11 Pin 12 Pin 13 Pin 14 Pin 15 Pin 16 Pin 17 Pin 18 CE when J2 is placed.

In case the display of Pocket PC shows PalmSens not connected, follow the next steps: - Check whether the > and < are shown consecutively on line 1 of the PalmSens LCD. If this not shown reset PalmSens by pressing ◄ ► ENTER ESC (four keys) simultaneously. - Check the 9-pin serial connector at the left-hand side of PalmSens - Check the serial connector of the Pocket PC. - Select ‘Connect PalmSens’ in the menu ‘Instrument’. - If the previous steps did not solve the problem, restart the program PalmScan or PalmTime. If the program still refuses to connect to PalmSens, the Pocket PC can be reset by pressing the small reset button of the Pocket PC using the stylus (See manual of Pocket PC). 2. In case PalmSens can not be switched on. - Check the adapter by measuring the voltage across pin 1 and the case of the mini-DIN connector. The reading must be at least 6 V. If this is not correct try another 6 V adapter (please note the polarity). - Change the NiMH batteries according to Appendix 3. - Reset PalmSens by pressing ◄ ► ENTER ESC (four keys) simultaneously. 3. In case the Pocket PC can not get connection with PalmSens. - Reset the Pocket PC by pressing the small reset button on the back or bottom of the Pocket PC using the stylus. (See manual of Pocket PC) 4. In case the Pocket PC is complete blocked it can be initialised completely. Press application button 1 and button 4 and press the reset switch simultaneously until the display fades completely. If possible remove the battery and replace it. Now turn the Pocket PC on and it should start complete fresh. Warning: All data and all programs will be lost when this hard reset is done. 5. In case PalmSens starts with the self test, but is switched off after that, recharge the batteries by using the ac-adapter. Contact Palm Instruments if the problems remain and send the information as shown in appendix 8. Appendix 8 Software modification request and bug report. The software may show malfunctions. Please report bugs to Palm Instruments by specifying as many details as possible. -------------------------------------------------------------------------------------------------User: Insitute/Company: E-mail: Pocket PC program: of Pocket PC) _______________________________ _______________________________ _______________________________ ________________ version ________ (see towline PalmSens firmware version: _______ (see LCD of PalmSens) Please send the stored method when relevant or specify the method parameters.
