3.5.3 Instructions
To set up a multi-channel RS485 programmer network, please follow the instructions detailed below…
•
Place the ‘RS485 Converter’ as close to the PC COM port as possible.
•
Connect the 9-way RS232 cable between the ‘RS485 Converter’ RS232 port and a spare PC
COM Port.
•
Connect an ‘RS485 Cable’ flat cable (must be an ‘crossed cable’ ) from either of the ‘RS485
Connectors’ on the Converter to the ‘RS485 FCC68 to 5-pin Molex Converter Module’
•
Connect a ‘5-pin Molex RS485 Cable’ to the ‘RS485 In’ connector on the first programmer in
the series.
•
Connect a ‘5-pin Molex RS485 Cable’ from the ‘RS485 Out’ connector on the first
programmer to the ‘RS485 In’ connector on the second programmer in the chain.
•
Connect a ‘5-pin Molex RS485 Cable’ from the ‘RS485 Out’ connector of the second
programmer to the connector of the third programmer…..and so on until you reach the last
programmer in the chain.
Important notes:
•
The RS232 cable between the ‘RS485 Converter’ and the PC COM Port should be kept as
short as possible i.e. no longer than 2m.
•
The RS485 Converter should be placed as close to the PC COM port as possible.
•
An RS485 terminator is NOT required on the last programmer.
•
The ‘RS485 In’ or ‘RS485 Out’ connectors are connected in parallel inside the programmer so
it does not matter whether the ‘In’ or ‘Out’ connector is used.
•
Each programmer on the RS485 network must have a unique ‘Node Address’ . The address
is set by connecting to either RS232 port and then using the ‘Set Node Address’ utility in
EQTools.
•
This mode of operation requires either the ISP-PRO or ConsoleEDS software utilities to be
running on the PC
3.5.4 RS485 FCC68 to 5-pin Molex Converter Module
The cable from the RS485 Converter to the first ISPnano programmer ‘RS485 In’ connector must be
terminated using the ‘RS485 FCC68 to 5-pin Molex Converter Module’ as the ISPnano uses a
smaller 5-pin Molex connector. The ‘Converter Module’ is a small circuit board which converts the
RJ11 connector from the RS485 Converter to the miniature 5-pin Molex connector used for RS485
connections on the ISPnano programmer. The flat cable from the RS485 Converter plugs in one end.
A ‘5-pin Molex RS485 Cable’ plugs in the other end and then connects to the first ISPnano
programmer in the chain.
