Pin number of Matrox Description
Iris GT Digital I/O and
power cable
connector (DB-25)
6 Open-collector auxiliary signal 6 (output).
Supported function: User-defined signal 6 (output).
7 Controlled-current output, designed to be connected to a
LED lighting device (0-500 mA).
Note that if your connected LED lighting device requires
24 V, the Matrox Iris GT requires a 24 V power source.
8 Do not connect.
9 Ground. This ground is reserved for use with the ground
from your power supply.
10 Do not connect.
11, 23 Power provided to your Matrox Iris GT. The power must be
either +12 V or +24 V +/- 10%. The amount of power
required is determined by the power requirements of the
devices attached to your Matrox Iris GT (such as a ring
LED).
12 Do not connect.
13 RS-232 receive.
14 Opto-isolated auxiliary signal 1 (input), positive.
Supported function: User-defined signal 1 (input).
Note: The negative component of this signal is internally
connected to the ground.
15 Opto-isolated auxiliary signal 3 (input), positive.
Supported function: User-defined signal 3 (input).
Note: The negative component of this signal is internally
connected to the ground.
16 Opto-isolated trigger input signal, negative.
Note that, in TTL format this pin must be connected to
ground.
17 Do not connect.
18 Open-collector auxiliary signal 5 (output).
Supported function: User-defined signal 5 (output).
19 Open-collector auxiliary signal 7 (output).
Supported function: User-defined signal 7 (output).
20, 21, 22, 24 Do not connect.
25 RS-232 transmit.
