  • Page 22: Programming The 60-890

    PROGRAMMING THE 60-890-003 The 60-890-003 is fitted with 12 separate un-terminated SPDT microwave switches. The unit’s architecture is shown in the default, un-programmed state in Figure 4-1 below. Each switch is controlled with a separate bit in the same programming sub-unit as outlined in Table 4-1.
  • Page 23 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 24 Switch closures are made using the pi40iv_Connect function and released using the pi40iv_Disconnect function. The following code snippet demonstrates the minimum steps required to operate a switch on a Pickering LXI unit. First a device session is opened on the card located at bus 0, device 20 inside the LXI unit at 192.168.1.100.
  • Page 25 SSH (Secure SHell) Interface Refer to the section “Command Line Control of Pickering LXI Instruments” on the following pages for details of how to open this interface and general information on the command set available. After opening an SSH session the 60-890 is controlled as follows: To select a multiplexer sub-unit on the LXI unit (card 1), type AD followed by the card number and sub-unit number eg: AD 1 2 (this will select multiplexer bank 2).
