Communication
Data and commands can be exchanged between the IDP-800 and DECS-200, DECS-200N, DECS-250,
DECS-250N, or DECS-400 using serial communication. In addition to serial communication, the DECS-
400 has the added capability of Ethernet communication with the IDP-800. When connected to an
Ethernet LAN, the display can be polled via Modbus to acquire data collected by the DECS-400
connected to the IDP-800.
DECS and IDP-800 communication applications are summarized in Table 1.

∗ Distributed Control System (DCS) interface offers pass-through communication to/from the
DECS-200, DECS-200N, DECS-250, or DECS-250N via the IDP-800 Ethernet port.
† Requires two IDP-800 display panels.
‡ Requires a multi-port Ethernet switch between an IDP-800 and single- or dual-DECS-400
controllers. An open port on the switch enables external (DCS) control and monitoring
communication between the IDP-800 and DECS-400.
Serial Communication
When the IDP-800 will be communicating with a DECS using RS-485 serial communication, the DECS
communication settings should be configured as follows:
•
Baud: 9600
•
Data length: 8
•
Parity: None
•
Stop bits: 2
•
Single DECS address: 247
•
Dual DECS address: 247 (DECS-A) and 246 (DECS-B)
