Control Options
Centralized serial Ethernet control systems provide
the most robust and complete HLX control, however,
comprehensive IR controllers and zone IR control are good
alternatives for most day to day activities.
Ethernet or RS-232 Serial Control
System controllers and PCs can send all setup and
control commands via the RS-232 serial port and receive
feedback.
• Important: observe the correct pinout for controlling the
HLX via RS-232 cable
• Serial control is capable of performing all commands
• See page 19 for details on using serial commands
IR Control Options
The HLX can be controlled through IR commands issued
at each zone, or via the IR inputs at the head end (see
example systems below). Either use an IR remote with a
receiver connected to the IR jack on the zone receiver, or
program an RF controller or other control system with HLX
IR commands and connect its outputs to the IR input jacks
on the 2248 zone card. (12 volt switches should be OFF, in
the up position.)

(a) If an automatic IP protocol is used to obtain an IP
address, the only direct way to obtain the new IP address
is to query the HLX Ethernet settings using RS-232, or
use front panel controls.
(b) All rmware updates must be performed via USB.

IR Control from Zones
An IR receiver connected to a zone receiver IR jack can be powered via connecting block in the zone, or powered
with 12 volts from the HLX. To enable HLX power, move the OUT dip switch to the down position to power a
compatible IR receiver in the zone. CAUTION: Can cause damage if used with incompatible IR equipment. Check
voltage and pinout.
