MAX-CSE and MAX-CSD10 Installation

MAX-CSE/MAX-CSD10 Operation/Reference Guide

The DB9 Device Port connector supports RS-232 communication protocols for PC data transmission.

This table’s wiring specifications are applicable to the rear RS-232/422/485 Device Port connectors on

the MAX-CSE.

IR/Serial Port: Connections and Wiring

You can connect one IR- or Serial-controllable device to the IR/Serial connector on the rear of the MAX-

CSE and MAX-CSD10 units.

This connector (FIG. 9) accepts the included IR Emitter (CC-NIRC) that mounts onto the device's IR

window, or an optional mini-plug (CC-NSER) that connects to the device's control jack. You can also

connect a data 0 - 5 VDC device.

Input/Output (I/O) Port: Connections and Wiring

The I/O port responds to either switch closures, voltage level (high/low) changes, or it can be used for

logic-level outputs. You can connect up to two devices each on MAX-CSE and MAX-CSD10 units.

A contact closure between the GND and an I/O port is detected as a Push.

 When used for voltage inputs, the I/O port detects a low (0 - 1.5 VDC) as a Push, and a high

(2.0 - 3.3 VDC) signal as a Release (this IO port uses 3.3V logic but can handle up to 5V

without harm).
