Overview

3 Overview

The PL-18 is a highly versatile port expander that adds RS-232, IR and

relay ports to an RS-232 controller, especially a Kramer RC device such as

RC-2, RC-2C or RC-62/RC-63. It acts as an all-in-one extended remote

control panel for control of A/V equipment—especially projectors and

associated equipment—in any room (such as classrooms, boardrooms, or

auditoriums).

The PL-18 Control Port Expander features:

• One bi-directional serial port for controlling RS-232 based devices

(for example, projectors) on RS-232/1

• One bi-directional port for receiving control commands from a PC,

touch screen, other serial controller or an RC series device on

RS-232/2

• Four relays for the simplified and centralized control of room

functions (such as lighting, closing blinds, screen settings, and so

on)

• Two IR output ports for IR control

• A USB port for firmware upgrade

To achieve the best performance:

• Use only good quality connection cables

• Avoid interference from neighboring electrical appliances that may

adversely influence signal quality and position your Kramer PL-18

away from moisture, excessive sunlight and dust

to avoid interference,

deterioration in signal quality due to poor matching, and elevated

noise levels (often associated with low quality cables)
