Mounting to an MP-4000To mount an RS-485 PONI onto the MP-4000, use theU-shaped mounting bracket and #6 32 x ¼” pan headscrews supplied with the MP-4000. Use this bracket onlywhen a URTD is not mounted to the MP-4000. If a URTD ismounted on the MP-4000, the RS-485 PONI can piggy backdirectly on the URTD. The machine screws supplied withthe RS-485 PONI are then used to screw into the moldedplastic mounting-holes of the URTD. Refer to the MP-4000Instruction Book IB02602002E for additional information. Toorder this mounting bracket use part number 7066C H0.Figure 6: Mounting to an MP-40003e. Mounting to an ATC-400To mount the RS-485 PONI to the rear of the ATC-400, use thestacking screws that are shipped with the RS-485 PONI. On therear panel of the ATC-400, there are two treaded holes that areto be used for attaching PONI type devices. Refer to Figure 7.Figure 7: Mounting to an ATC-400Mount the RS-485 PONI with the label facing up, the RS-485connector on the left and the ribbon cable on the right, asyou are facing the rear panel of the ATC-400.Attach the ribbon cable from the RS-485 PONI to thereceptacle of the IQ device, as shown in Figure 3 on Page 2,and firmly tighten the screws on the plug lock assembly.3f. Mounting to an IQ Transfer IITo mount the RS-485 PONI to the rear of the IQ Transfer IIuse the stacking screws that are shipped with the RS-485PONI. On the rear panel of the IQ Transfer II, there are twosets of threaded holes that are to be used for attaching PONItype.devicesUse either set for mounting the RS-485 PONI. Refer toFigure 8. Mount the RS-485 PONI with the label facing up,the RS-485 connector on the left and the ribbon cable on theright, as you are facing the rear panel of the IQ Transfer II.Attach the ribbon cable from the RS-485 PONI to thereceptacle of the IQ device, as shown in Figure 3 on Page 2,and firmly tighten the screws on the plug lock assembly.Figure 8: Mounting to an IQ Transfer IISimplified Wiring RulesThe RS-485 PONI provides the user with a half-duplexEIA/RS-485 network connection. EIA/RS-485 is a multi-dropindustrial-grade communications standard.It is a “balanced differential” signal which uses a twisted-paircontaining the “A” and “B” signals and a common. For thisreason, it is very important to carry all three conductors tohelp ensure a high-quality communications network.
