Equinox Systems RS232-RS485 instruction

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).

∙Plug the 9-way RS-232 cable into the port on the RS-232 to RS-485 convertor and connect further PRO101 programmers as shown in the diagram below.

Figure 10

∙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 PRO101.

∙Plug another RS-485 network cable from the ‘RS-485 Output’ connector on the rear panel of the first PRO101 to the next PRO101 in the chain.

∙A return RS-485 cable from the last PRO101 in the chain to the RS-485 convertor is NOT required.

∙Power up the PC.

∙Plug in the power supply adaptor supplied with the RS-232/RS-485 convertor into a spare mains socket.

∙Power up all PRO101 programmers.

∙Launch the ISP-PRO software on the PC and set up the required number of PPM’s within the software.

∙Test that all PPM’s are communicating with the PC at their correct ‘Node Address’. (The Node Address may be changed while the programmer is powered up).

∙When all PRO101’s are recognised by the ISP-PRO software, power down all programmers and replace lids.
