CONTROL OPTIONS

Techconnect Control learns and replicates codes sent from a device’s infrared remote control.

An IR emitter integrated into the front panel is adequate for small rooms.

For larger rooms three external wired IR emitters are included – one with a 10m cable, and two

without cables. Techconnect Minijack cables are suitable to extend these.

NOTE: There is no theoretical cable length limit on IR cables.

NOTE: Remote controls which come with projection screens are often RF – not IR. To control

these screens use the 12v trigger.

RS-232

Professional control format used to control a variety of devices including projectors. More

reliable than IR and uses two-way communication with the control device to confirm commands

has been received.

Requires 3-core cable. Limited cable lengths.

NOTE: If using RS-232 the TC2-CTL3 needs to be mains-powered.

12v Trigger

Simple trigger voltage commonly used to activate projection screens. Requires 2-core

unshielded cable.

NOTE: If using 12v Trigger the TC2-CTL3 needs to be mains-powered.

RS-485

Using the same codes as RS-232, this protocol offers longer cable distances of around 100m,

and only requires 2-core cable. Few AV devices can decode RS-485.

If using an additional Control module to extend the keypad this terminal is used to connect the

slave module to the master.

NOTE: If using RS-485 the TC2-CTL3 needs to be mains-powered.
