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)
