Pre-operation Checks (Unpacking)
1. Check the module for transport damage and report any damage immediately to Pickering Interfaces.
Do not attempt to install the product if any damage is evident.
2. Ensure that the designated area for the product is of flat and solid construction to support its weight.
!
Refer to the Warnings and Cautions at the front of this manual
The module is designed for indoor use only.
Installing the Microwave Multiplexer
The 60-890-053 may be mounted on a desk top or fitted into a standard 19 inch rack (rack mounting flanges are supplied
with the unit that can be fitted to the sides of the front panel). When fitting into a rack it is important to provide adequate
support using side brackets or runners, the mounting holes in the front panel flanges are designed only for securing the
unit in the rack and must NOT be used to support the weight of the whole unit.
The 60-890-053 relies upon forced air cooling. Internal fans draw air through slots in the front panel and expel air through
two vents in the rear panel. When positioning the chassis, make sure that there is adequate clearance to allow unrestricted
air flow through these vents. The locations of the air intakes and outlets are shown in Figures 3-1 and 3-2.
Power is supplied to the rear of the unit using a standard IEC power lead and the power on/off switch is located next to the
power inlet socket. The unit is supplied with a suitable Earthed mains power lead, If a different lead is used it is important to
ensure that an adequate Earth connection is present. When mounted in a rack, provision should be made to allow access to
the rear of the unit. This is to enable the operation of the power on/off switch and the Reset button. The rear panel layout is
shown in Figure 3-2.
The Microwave Multiplexer is controlled by the host computer via an Ethernet interface. The RJ45 socket on the rear of
the unit can be connected to a hub or switch via an Ethernet cable to allow control over a local area or wide area network.
Alternatively a crossover Ethernet cable can be used to connect the unit to a laptop PC and local control can be carried out
isolated from a network. The IP address of the unit has to be manually or automatically configured before it can be used on
a network, please refer to the following section “Setting the IP Address” and the “LXI Getting Started Guide” document to
carry out this process.

Setting the IP Address
To use the 60-890-053 Microwave Multiplexer over a LAN connection it should be set up and configured as described in the
“LXI Getting Started Guide” document.
If the IP address is to be set manually and before connecting to a network, contact your IT department so they can give you
the correct settings for:
• IP Address
• Subnet Mask
• Default Gateway
• DNS Server(s)
Once you have the required information, the IP configuration window is used to manually set the IP address. This is shown
in Figure 3-4.
The current IP address setting of the 60-890-053 is indicated on an LCD display on the rear panel of the chassis.
Incorrect setting will result in a loss of communication and may also be indicated by a red LAN LED on the front panel. If
this does occur press and hold the LAN Reset button on the back panel of the device for a full factory reset (see Section 6
“Troubleshooting” for details).

Section 4 - Programming
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.
Firstly a communication session to the LXI unit is established. This provides a session handle to the remote LXI unit which
must be used in all subsequent communication with the unit.
Then a specified card on the remote LXI unit is opened and a handle to that card obtained, this handle must be used in all
subsequent function calls to that card.
To operate a switch, the PIPLX_OpBit command may be used to select an individual output. The simplest way to clear
a switch is to call PIPLX_ClearSub. Please note that a maximum of one connection may be made on any individual
switch sub-unit, closure of an output of the switch will cause any other previously made connections on that switch to be
released.
After use the card should be closed and the LXI session released to free the card and the LXI unit for other use.

IVI Driver, pi40iv
Using the pi40iv driver, the pi40iv_InitWithOptions function should be used to establish a session on the unit.
Switch closures on the unit 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.
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.
Then a switch closure of the first relay is made then disconnected.
Finally the session is closed.
ViSession vi;
ViStatus err;
ViRsrc rsrc_name = “TCPIP::192.168.1.100::0.20::INSTR”;
ViString options = “Simulate=1,RangeCheck=1,QueryInstrStatus=0, \
Cache=1,DriverSetup=Model:60-890-053;”;
err = pi40iv_InitWithOptions(rscr_name, VI_TRUE, VI_TRUE, options, &vi);
if (err == VI_SUCCESS)
{
pi40iv_Connect(vi, “comA1”, “chA1”);
.
.
.
pi40iv_Disconnect(vi, “comA1”, “chA1”);
}
pi40iv_Close(vi);
Notes:
The channel names for the switches will be as follows:
comA – chA1, chA2, chA3, chA4, chA5, chA6, chA7, chA8
comB – chB1, chB2, chB3, chB4, chB5, chB6, chB7, chB8
comC – chC1, chC2, chC3, chC4, chC5, chC6, chC7, chC8
comD – chD1, chD2, chD3, chD4, chD5, chD6, chD7, chD8
comE – chE1, chE2, chE3, chE4, chE5, chE6, chE7, chE8
comF – chF1, chF2, chF3, chF4, chF5, chF6, chF7, chF8
