Use an ADPT-MR5-RS485 isolated communications adapter to interface an MR5 controller with a BAS. The MR534AFDV controller models include the communications adapter.
The MR534AFDN controller models do not include the communications adapter; to add network communications, purchase the adapter separately. For more information about the Johnson Controls® Verasys® systems see http://verasyscontrols.com/.
Refer to the MR5 Series Panel Mount Case Controller Technical Bulletin (LIT-12013019), and the MR5 Series Panel Mount Case Controller Installation Guide (Part No. 24-07664-03388) for more information about how to use the adapter with the MR5 controller.
