Installing Dionex Devices
PDA-100 (DX-LAN) HPLC Detector: Installation

Hardware Installation

Device Connection:

Fig.: Rear panel

In order to communicate with a host computer running Chromeleon software, you must install the DX-LAN interface (see  Installing the DX-LAN Card). On the instrument's rear panel, connect the RJ-45 (10BASE-T) connector:

a) To the computer, using a crossover cable, or

b) To an Ethernet switch (Dionex part no. 061610 in North America; Dionex part no. 061655 outside North America), using a DX-LAN cable.

Connect an unshielded twisted-pair cable DX-LAN cable (Dionex part no. 960281) to the Ethernet switch.

For more information, refer to  Connecting Dionex Devices via DX-LAN 10BASE-T.

 

Relay/TTL Control

The PDA-100 Ship Kit includes a 12-pin connector for relay and TTL connections. To attach individual wires and twisted pairs to the connector, strip the end of the wire(s), insert it into the connector, and tighten the locking screw(s) with a screwdriver.

The following table indicates the pin assignment for relay and TTL connections:

Pin Assignment Input Pin Function

1 Relay 1 output Active 

2 Relay 1 output GND 

3 Relay 2 output Active 

4 Relay 2 output GND 

5 TTL 1 output Active 

6 TTL 2 output Active 

7 TTL 1 input Active Autozero

8 TTL 2 input Active Remote inject

9 TTL 3 input Active UV lamp on/off

10 TTL 4 input Active VIS lamp on/off

11 TTL input or output GND 1 

12 TTL input or output GND 2 

 

 Note:  

Connections 1 and 2 can be configured in Chromeleon to switch any low-voltage control. The switched current must be less than 200 mA and 42 V peak.

Device Settings:

No special settings required.

Restrictions:

Only two Photodiode Array Detectors are permitted on one server PC.

 

Software Installation

Install the Device Driver in the Chromeleon Server Configuration. (For more information about the program, refer to Software Installation and Communication  The Server Configuration Program.)

  1. Start the Chromeleon server.

  2. Start the Chromeleon Server Configuration program.

  3. Under Sharable Devices verify that the DX-LAN card to which the instrument is connected is entered.

  4. Add the detector to the timebase. Select Add Device on the Edit or context menu, and then select Dionex from the Manufacturers list box and PDA-100 Detector from the Devices list box.

  5. The following settings are required:

On the General tab page, select a free COM port. Verify that the Demo Mode is disabled. Select and configure the connected instrument by clicking Query for Device ID.

The Signals tab page indicates the signal assignment of the respective channels. Change the assignment only in exceptions.

On the State Devices tab page, verify that the check boxes for the installed relays and/or remote inputs are selected.

The Error Levels tab page classifies the severity of any errors that occur. It is generally not necessary to change the default settings.

On the Calibration tab page, enable/disable calibration functions for an instrument and set reminders for individual functions.

On the Diagnostics tab page, you may enable or disable the diagnostic functions for an instrument.

  1. To control the PDA-100 detector, connect the HPLC_Summit.pan (detector as part of an HPLC system) Control Panel in the Chromeleon client to the corresponding timebase.

Application

The User Help section provides an overview of the different commands that are supported for the detector; refer to Commands for Controlling Dionex Devices  Dionex Detectors and  Dionex PDA/PDA-100/PDA-3000 Photodiode Array Detectors.

For different program examples for the PDA-100 detector, refer to Practical Tips for Device Control  Detector Control in the User Help section.

 

Troubleshooting

For a list of all error messages that might appear in Chromeleon, refer to the Error Levels tab page in the Server Configuration program.
