Equinox Warranty Information This product is guaranteed by Equinox Technologies UK Limited for a period of 12 months (1 year) after the date of purchase against defects due to faulty workmanship or materials. One guarantee covers both parts and labour. Service under the guarantee is only provided upon presentation of reasonable evidence that the date of the claim is within the guarantee period (e.g. completed registration/guarantee card or a purchase receipt).
Equinox Technologies UK Ltd. can not be held responsible for any programming problems which are ‘out of our control’. This type of problem is usually listed in the ‘Errata Sheet’ for the particular device being programmed and is available from the silicon vendor. Information contained in this manual is for guidance purposes only and is subject to change. E&OE. iv RS232-RS485 Convertor Manual V1.
Electromagnetic Compatibility (EMC) Compliance The ‘RS-232 to RS-485 Convertor’ is a CE Approved Product. It is designed for use in an ESD controlled environment i.e. development or production. This means, therefore, that the user must ensure that there is no possibility of damage from electrostatic discharge (ESD). Since the devices and equipment to which this product is likely to be connected may well themselves be susceptible to ESD, this should not pose any difficulty.
Technical Support It is often the case that users experience problems when installing or using a product for the first time. Equinox are unable to answer technical support questions about this product or its use by telephone. If you have a technical support problem, please consult the following list for help: ? Manual ? On-line help Press for help at any time. The help system is context-sensitive. Simply press on any error message and the Possible causes of the error should be listed.
Associated Product Documentation This manual provides a detailed description of the ‘RS-232 to RS-485 Convertor’ hardware only. For detailed information about the systems in which this module is used and the associated hardware modules and software support products, please refer to the sources of information listed in the table below.
1.0 Overview 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 PRO101, PRO104 and PRO108 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. 1.

2.1 RS-232 to RS-485 Status LED Indicators Figure 4 No 1 LED Colour Red 2 Yellow 3 Green Status Description Indicates that the PC has enabled RS-485 transmission. This means that the RS-485 driver has been enabled allowing the convertor to drive the RS-485 line to the remote system. Indicates that the remote RS-485 system is transmitting data to the PC through the convertor. The LED will flash when data is being transmitted. PC is transmitting data to the remote RS-485 system.
2.3 J1 RS-232 Serial Communications Port Connector type: Purpose: 9-Way Male D Connector (Female) Connects to PC COM port (RS-232) This connector is an RS-232 serial port which connects to a spare RS-232 PC COM (serial) port. The pin-out of this connector is detailed in the table below. The ‘RTS’ pin must be asserted by the PC COM port in order to enable the RS-485 line driver. J1 Pin-out: Pin No.
2.4 J2 & J4 Isolated RS-485 Connectors Connector type: Purpose: FCC68 Socket 6-Way (Accept RJ11 plugs) Connects to RS-485 remote system e.g. PRO101/4/8 programmers These two connectors are opto-isolated RS485 connectors for communicating with the remote RS-485 system(s). The connectors are wired in parallel so each socket is the same as the other. The ‘RS-232 to RS-485 Convertor Module’ is supplied with two RJ11 flat cables for connecting between this module and the RS-485 remote system.
3.0 PRO101 – Multi-Channel RS-485 Operation 3.1 Overview It is possible to network up to 16 PRO101 programmers on an RS-485 network and control them from a single ‘Supervisor PC’ running a single session of the EQTools/ISP-PRO software. This scenario requires that each PRO101 programmer is set to ‘RS-485’ and that a unique ‘Node Address’ is set for each programmer.
3.2 PRO101 Hardware Installation Instructions • Place the PRO101 programmers side-by-side on a flat surface allowing sufficient space in front of each programmer to place the ‘ISP Interface Modules’ and ‘Target Systems’. • Remove the lid of each programmer by removing the four screws in the lid. • Set the ‘Communications Mode Switch’ (S2) to ‘RS-485’. • Set the Communications Node Address to the required unique address (0 to 15).
4.0 PRO104 – 4 Channel Eurocard Rack Production ISP System 4.1 Overview The PRO104 programmer contains 4 PPM programming modules on an RS-485 network. These are controlled from a single ‘Supervisor PC’ running the ISP-PRO software. An RS232 to RS-485 convertor is required to convert the RS-232 signal from the PC COM port to an optically isolated RS-485 signal suitable for interfacing with the PPM’s on the network. It is possible to expand from 1 up to 4 PRO104’s (16 PPM Boards in total).
4.2 PRO104/108 Hardware Installation Instructions • Place the PRO104/108 programmer(s) on a flat surface allowing sufficient space in front of each programmer to place the ‘ISP Interface Modules’ and ‘Target Systems’. • Plug the 9-way RS-232 cable into the port on the RS-232 to RS-485 convertor. Figure 12 • Plug an RS-485 network cable from one of the RS-485 outputs on the RS-485 convertor to the ‘RS-485 Input’ connector on the rear panel of the first PRO104.
