Connecting your Controller

Honeywell Universal Modbus Interface Reference 13

Using an RS-485 Adapter

Honeywell recommends using the Stallion EasyConnection 8/32 ISA, 8/32 PCI,

8/64 ISA or 8/64 PCI adapters with the Stallion RS-232 to RS-485 8-port dual

interface asynchronous module. Honeywell has qualified this adapter. Use of

another adapter may produce unexpected results.

Installing the Stallion EasyConnection Serial Adapter

Stallion EasyConnection serial adapters are suitable for connection to RS-232,

RS-422 and RS-485 devices.

Install the adapter, port module, and driver in the server as described in the

Stallion documentation.

Connect a port on the Stallion port module directly to the RS-485 network as

shown in “Stallion RS-485 (2-wire) Connections” on page 13 and in “Stallion

RS-485 (4-wire) Connections” on page 14. Next, connect your Control Products

controllers to the RS-485 network.
