Isolated RS232 to RS485 Convertor (Universal Power Supply) |
|
|
|
|
|
| |
The RS-232 to RS-485 Convertor module converts RS-232 levels from a PC COM port to RS-485 levels suitable for interfacing with the Equinox PPM3-MK2 and PPM4-MK1 Production ISP programmers. The module provides an optical isolation barrier between the PC COM port and the RS-485 bus which serves to protect the PC from ESD damage.
The RS-485 Convertor is primarily designed to allow networking of 2 or more Programmer Modules from one PC. This is achieved by daisychaining programmers on the RS-485 bus. Each programmer must be given a unique 'Node Address' on the bus so that the PC software can communicate with it.

Main Features |
|
- Converts serial RS-232 signals from e.g. a PC COM port to serial RS-485 signals
-
Opto-isolated barrier between RS-232 and RS-485 signals
-
Connects to PC via 9-way serial D-connector
-
RS-485 devices connect to covertor via RJ11 plug-in connectors
-
Supports daisychaining of Equinox PPM-MK2 and PPM4-MK1 programmers
-
Traffic-light Status LEDs indicates Transmitted and Received data
-
RS-485 line driver can be enabled / disabled via PC hand-shaking line
|
|
Networking of programmers |
|
- Up to 16 Programming Modules can be daisy-chained from a single PC via the Equinox RS-485 Programmer Bus
-
Each Programming Module must be assigned a unique 'Node Address' via a DIP-Switch on each module
-
Equinox 'ISP-PRO - Production ISP Software' is required to control more than 1 programmer on the network
|
|
Status LEDs |
|
|
The Convertor features 3 Status LEDs which indicate whether data is currently being transmitted as follows:
- RED - RS485 TRANSMIT driver is ENABLED (via RS232 handshaking line)
- GREEN - PC is tranmitting data via RS232 to the RS485 convertor
- YELLOW - Data is being transmitted from an RS485 device, through the convertor and will be converted to RS232 levels
