1 Introduction

1.1 Scope and definitions

This manual provides installation, operation and maintenance instructions for the use of

two Edwards interface kits:

• D372-15-805 USB Pump RS232 Interface Kit

o to connect a PC’s USB port to an Edwards pump’s RS232 port

• D372-15-810 SLTA-10 Pump LON Interface Kit

o to connect a user-provided SLTA-10 to an Edwards pump’s LON port

Read this manual before you install and operate either of those kits.

Important safety information is highlighted as WARNING and CAUTION instructions; you

must obey these instructions. The use of WARNINGS and CAUTIONS is defined below.

WARNING

Warnings are given where failure to observe the instruction could result in

injury or death to people.

CAUTION

Cautions are given where failure to observe the instruction could result in damage to the

equipment, associated equipment and process.

The following IEC warning labels appear on the pump:

Warning – refer to accompanying documentation.

Warning – Edwards offers European customers a recycling service.

The units used throughout this manual conform to the SI international system of units of

measurement.

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.

D372-15-860 Issue Draft 1

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 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.

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.

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.

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.

LON RS232 ETHERNET

Gen 1 (iQ, Mk1 iH)   

Gen 2 (Mk2–5 iH/iL, iF)   

Gen 3 (IPX/EPX EUC, iGX/GX   

OTB, pHMB)

Gen 4 (iXH/iXL, pXH, GXS/CXS)   

System Controllers (Various)   

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.

D372-15-860 Issue Draft 1

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.
