1.2 Description
1.2.1 D372-15-805 USB Pump RS232 Interface Kit
The main component of this kit is D49951139, and Edwards cable assembly with a PC USB TYPE A plug at one end and a pump RS232 5-way XLR plug at the other end.
A USB RS232 adapter, manufactured by FTDI, is built into the USB plug. The 5-way XLR plug is intended to be connected into an Edwards pump’s PDT socket.
The kit also includes D37370726, an Edwards cable assembly to convert the 5-way XLR plug to an RJ12 plug, for use with older pumps where the PDT connector is an RJ12 socket.

The primary purpose for this kit is to allow an Edwards pump with an RS232 interface to be supported using various Edwards PC software tools such as EST (Edwards Support Toolkit), FEUU (Flash EPROM Upgrade Utility) and others. So, the final component of this kit is D37215870, an Edwards CD-ROM containing FTDI USB drivers for the Windows operatingsystem, along with this instruction manual. Note that the CD-ROM does not contain the actual Edwards PC software support tools, which must be acquired separately.
1.2.2 D372-15-810 SLTA-10 Pump LON Interface Kit
The main component of this kit is D49951141, an Edwards cable assembly with two 2-way Weidmuller plugs at one end and a pump LON 4-way XLR plug at the other end.
The two Weidmuller connectors plug into a SLTA-10, an RS232 LON adapter box, which is manufactured by Echelon. The black Weidmuller connector carries 24 volts power from the pump to the SLTA-10. The orange Weidmuller connector carries LON network communications between the SLTA-10 and the pump.
The kit does not include the actual SLTA-10, which the user must purchase separately, either directly from Echelon http://store.echelon.com/network_interfaces.asp or from an Echelon distributor such as AVNET Express or RS.

D372-15-860 Issue Draft 1
There are several variants of the SLTA-10. The one required for use with Edwards pumps is
“SLTA-10/TP-78 Serial LonTalk Adapter” and the Echelon part number is “73352R”. It is very important to purchase that specific variant, which is the only one that has the “TP-78” (Twisted Pair – 78k baud) transceiver compatible for use with Edwards pumps.
The SLTA-10 has an RS232 9-way D-sub socket, which is intended to be connected to a PC via an appropriate interface cable. However, neither the user-provided SLTA-10 nor the Edwards provided SLTA-10 Pump LON Interface Kit provide such an interface cable. The user must purchase their own means of connecting their PC to the SLTA-10. Edwards recommends, but does not supply, suitable USB RS232 adapters from FTDI: e.g.
US232R-10 Premium USB-Serial Converter |
US232R-100 Premium USB-Serial Converter |
The ‘-10’ and ‘-100’ specify the cable length: 10cm (~4”) or 100cm (~40”), respectively.
Those FTDI US232R-10 and US232R-100 products can be ordered directly from their on-line shop http://apple.clickandbuild.com/cnb/shop/ftdichip or from distributors such as DigiKey, Farnell, Mouser or RS. They can also be ordered from EasySync, via their own web-site http://www.easysync-ltd.com/category/115/usb-to-rs232.html z
whose part-numbers are ES-U-1001-R10 and ES-U-1001-R100, respectively.
When using a USB RS232 adapter with the SLTA-10, the connector locking nuts on both parts tend to clash with each other.

The SLTA-10 Pump LON Interface Kit therefore includes a 9-way D-sub “gender changer” (a back-to-back 9-way D-sub plug and 9-way D-sub socket) whose own locking screws can be removed, allowing it to be fitted between the USB RS232 adapter and the SLTA-10.
Remove these locking screws
The sole purpose for this kit is to allow an Edwards pump with a LON interface to be supported via an SLTA-10 using various Edwards PC software tools such as EST, FEUU and others. So, the final component of this kit is D37215870, an Edwards CD-ROM containing Echelon LON drivers and associated utilities for the Windows operating-system, along with this instruction manual. Note that the CD-ROM does not contain the actual Edwards PC software support tools, which must be acquired separately.
This table shows which Edwards pump controller generations and types include a LON interface.

Note that it is only necessary to connect a PC to a pump controller via a LON interface for Gen 1 pumps: iQ and Mk1 iH. All later generations of pumps have an RS232 interface, which is the Edwards recommended method for using with Edwards PC support software tools.

1.2.3 Interface Kit Summary
If you need to run Edwards PC software tools to support a Gen 1 pump (iQ or Mk1 iH) then you must connect the PC to the pump via its LON interface. The currently preferred method for doing that is to purchase your own FTDI USB RS232 adapter and your own Echelon SLTA-10 RS232 LON adapter and to use them in conjunction with D372-15-810, the Edwards SLTA-10 Pump LON Interface Kit.
However, if you need to run Edwards PC software tools to support a Gen 2 or later generation pump (Mk2-5 iH, iL, iF, IPX/EPX EUC, iGX/GX, iXH/iXL, GXS/CXS) then you should connect the PC to the pump via its RS232 interface. The currently preferred method for doing that is to use D372-15-805, the Edwards USB Pump RS232 Interface Kit.
