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.
