    Fig. 2.4 Typical RTD installation 2.6.5 CONNECTING THE RS-485 DEVICE NETWORK The nVent RAYCHEM NGC-UIT display is typically linked to a network of RAYCHEM NGC-30-CRMs/- CRMSs and optional RMM2s and PLIs. These are connected to the RAYCHEM NGC-UIT using an RS-485 communication cable (shielded, two conductor, twisted pair).
  • Page 8 Fig. 2.5 RS-485 network configuration for the NGC-UIT system In order for the nVent RAYCHEM RS-485 network to work properly, you must enable the termination resistor for the first and last device. The devices shown in gray in Fig. 2.5 represent the devices for which you must enable the termination resistors.
  • Page 9 Optional RMM2 Installed in the Field Refer to the nVent RAYCHEM RMM2 Installation Instructions (H56848) for field installation instructions. You must connect a RS-485 connection from the RMM2 to an open nVent RAYCHEM RS-485 connector on the NGC-30-CRM/-CRMS board in the RAYCHEM NGC-30 panel.
