UTILITY CONTROL INTERFACE
DESCRIPTION
LogiConverter is a logic interface unit that facilitates control of studio, AV, and similar equipment. LogiConverter creates
isolated SPST relay outputs from opto-isolated logic-level input signals. Four channels of interface are provided. They can
operate independently (for “start-only” use) or in pairs (for “start-stop” use). Each channel can be user-programmed to
generate momentary or maintained relay closure outputs, with several modes of input control.
INSTALLATION
Connection to the four LogiConverter inputs is via the 15-pin D connector. All inputs are opto-isolated. Input voltages
should be between 5 and 24 VDC. For connection to external contact closures, or equipment that provides “open
collector” (ground-sink) interface, connect the + input to any +12V terminal. Connect the – input to the open collector, and
connect any LogiConverter GND pin to the emitter.
Connection to the LogiConverter relay outputs is via plug-in terminal blocks. Remove about 1/8” of insulation, insert wires
into the connector, and tighten the screws. Be sure that no bare wiring is exposed.
PROGRAMMING
LogiConverter has 24 possible modes of operation….read carefully!
The four input/output channels can operate independently (“start-only”) or in pairs (“start-stop”, or “set-reset”).
If start-stop operation is selected, channels 1 & 2 are paired, and channels 3 & 4 are paired. The various modes are
programmed using the 8 dip switches, SW1 thru SW8, accessible from the front of the unit. They function as follows:
SW1 Selects input mode of Chan. 1 SW5 Selects input mode of Chan. 3
SW2 Selects input mode of Chan. 2 SW6 Selects input mode of Chan. 4
SW3 Selects output mode of Chan. 1 SW7 Selects output mode of Chan. 3
SW4 Selects output mode of Chan. 2 SW8 Selects output mode of Chan. 4
SW1 thru SW4 affect channels 1 & 2; SW5 thru SW8 affect channels 3 & 4 in the same ways.
Each channel has an “input mode” switch. Since channels 1 & 2 can operate as a pair, these switches affect both inputs.
For independent (“start-only”) operation, both SW1 and SW2 must be OFF . An input at Chan. 1 will produce an output at
Chan. 1. An input at Chan. 2 will produce an output at Chan. 2. There is no interaction.
There are two modes of paired (“start-stop”) operation: non-latching and latching. If non-latching operation is selected, an
input at Chan. 1 will cause an output at Chan. 1. Removing the input from Chan. 1 will cause an output at Chan. 2. This
mode is recommended for maintained (continuous) input signals only. To select this mode, SW1 should be OFF, and
SW2 should be ON. (The Chan. 2 input is not used in this mode.)
If latching operation is programmed, an input at Chan. 1 will cause an output at Chan. 1. Additional inputs to Chan. 1 will
produce no output; an input to Chan 2 must be applied to reset the latch, which will also cause an output on Chan. 2. To
select this mode, both SW1 and SW2 must be ON. (SW5 and SW6 have the same effects on input channels 3 and 4.)
Each channel has an output mode switch. If SW3 is OFF, the Chan 1. output will be a momentary closure (pulse). If SW3
is ON, the relay closure will be maintained for the duration of the input signal. SW4 affects Chan. 2 in the same way, as
does SW7 for Chan. 3 and SW8 for Chan. 4.
