3.8. GPI Remote Control Ports
The rear panel of the MIMO88 offers 8 GPI inputs (16) for 0-10 VDC continuous control voltage. Each of
these inputs can be connected to an external physical device (potentiometer, contact closure, continuously variable
voltage 0-10V DC, etc.) and assigned to a MIMO88 function, as for example:
Input, output channel or matrix crosspoint volume remote control by means of a WPVOL physical
knob or an Ecler WP Series WPVOL-IR remote control
MUTE or SOLO activation/deactivation by means of a switch or contact closure
Recalling a preset with a push button or contact closure
GPI connectors are screw terminal blocks with three-contacts. The wiring is as follows:
Positive, + 10 VDC
Variable voltage, 0-10 VDC
Ground
Connecting cables can be up to 500 meters with a minimum section of 0.5 mm
Consult your ECLER dealer or www.ecler.com about the WP series remote control wall panels and other
accessories available for connection to the REMOTE/VCA port.
3.9. GPO Remote Control Ports
The rear panel of the MIMO88 offers 8 NO/NC (normally open/ normally closed) relay outputs (17). Each of
these outputs may be assigned to a MIMO88 function, such as a button of EclerNet Manager (MUTE key, SOLO
key, etc.). This makes it possible to interact with external devices such as projection screen motors or movable
partitions, lights, sirens, other equipment GPI entries, etc.3.10. Remote control RS-232 Port
3.10. Remote control RS-232 Port
The built-in RS-232 port in the rear panel allows an external device to communicate with an MIMO88 unit
via a serial connection. Said connection uses the TP-NET protocol syntax so to enable the external device to
obtain the value of any of the parameters of the MIM088 unit (by "GET" commands) and/or modify said values
("SET" commands). See the TP-NET protocol manual for more information.
The serial connection should comply with the following specifications:
Baud rate: 57600 (fixed, no auto negotiation)
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
