Page 7: Warnings And Cautions
If the unit has removable modules, unused slots in the chassis must be populated with blanking panels to prevent access to user I/O signals that may be present. Blanking panels are available to order from Pickering. If the product is not used in this manner for example by using an extender card then additional care must be taken to avoid contact with exposed signals. - Page 8 Warnings & Cautions CAUTION - Product Documentation Symbol Suitably qualified & trained users should ensure that the accompanying documentation is fully read and understood before attempting to install or operate the product. Safety Instructions Safety Instructions All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user I/O signals (refer to the Maintenance Section).

Page 17: Programming The Microwave Multiplexer
Section 4 - Programming Programming the Microwave Multiplexer The 60-890-053 is a microwave multiplexer constructed from six 8-channel (SP8T) microwave switches. Signals paths can be set between the common terminal and any one of the 8 positions or to no connection. The initial state of the SP8T switches is with the common terminal open circuit and all channels open circuit. - Page 18 Section 4 - Programming Table 4-1. 60-890-053 LXI Microwave Multiplexer - Sub-unit/Bit Allocation Switch Signal Path Signal Path Switch No. Sub-unit Type (relay energized) (relay de-energized) RL1 C to 1 RL1 Open RL1 C to 2 RL1 Open RL1 C to 3 RL1 Open RL1 C to 4 RL1 Open...
- Page 19 Direct I/O Driver, piplx The Direct I/O driver is composed of a suite of separate libraries which interact to provide full control of a Pickering LXI unit. In the case of a switch card the communications library picmlx, and the switching library piplx, are needed.
- Page 20 The following code snippet demonstrates the minimum steps required to operate a switch on a Pickering LXI unit. Firstly a device session is opened on the card located at bus 0, device 20 inside the LXI unit located at 192.168.1.100.
- Page 21 Figure 4-2. 60-890-053 LXI Microwave Multiplexer - IVI Architecture Showing Channel Names (default switch positions shown) The implementation of a MUX switch (comA to comE) in the Pickering driver requires explicit disconnection of a previously connected path before a new path may be selected.

Page 23: Command Line Control
Command Line Control of Pickering LXI Instruments Overview Command line control of the Pickering LXI device range was added in firmware release 2.11. The utility provided was ported to the LXI instrument from the Windows utility PILMon and provides identical functionality. - Page 24 Section 4 - Programming Step 2 - Enable the SSH server Select the Instrument Control page from the main menu Click on the Start button to start the SSH server. The SSH server is now operative and instrument control access is available from an external SSH client application. Notes: The password and state of the SSH server are stored in non-volatile memory within the LXI device and so will remain in effect even after a power cycle.
- Page 25 Section 4 - Programming Instrument Control from an SSH Client In the following examples the SSH client PuTTY is used, the user will have to adapt the instructions for any other client. First start up the SSH client and enter the IP address of the LXI device. The user will be prompted for a login name and password.
- Page 26 Before attempting to control a card it is important to understand the switch architecture of that card and to know how to address the required switch. Each Pickering switch card is represented as a set of one or more sub-units, each sub-unit containing one or more switches.
