RS-232/MLC/IR control port — The PVS switcher can be
controlled via an RS -232 connection directly from a host
computer, a control system, or a MediaLink Controller (MLC).
For IR remote control, connect an Extron IR Link to this port.
RS-232 connection can be used to configure the PVS switcher.
C onnect a cable between this port and an optional Extron MLC
MediaLink Controller or an optional IR Link IR signal repeater.
• The MLC provides remote control of input switching and volume.
• The IR Link accepts modulated IR signals from a remote control
(e.g. the Extron IR 452 remote) enabling the remote control to be used for
selecting the switcher inputs.
W ire the captive screw connector and connect it to a computer or control
system, an MLC, or an IR Link, as shown in figures 2-9 through 2-12.

Figure 2-9 — Connecting an MLC 104 to the switcher
N The PVS 204SA power supply can support a typical system, for example:
• a PVS 204SA
• 4 PVT transmitters
• 2 or 4 speakers (see “Speaker Configuration” later in this chapter for details)
• an MLC 104 IP Plus with an IRCM DV+
• an MLP 101 D
• If an SCP 104 is used in the system, the MLC 104 Plus MUST have its own
power supply.
• The PVS 204SA provides sufficient power to run an MLC 104 IP or any
MLC 52 RS model.
