122 Appendix E: Connection modules
6 AUX(USER)_OPENC_OUT6 6 Open-collector auxiliary signal 6 (output).
Supported function: User-defined signal 6 (output).
7 CCS 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 Reserved 8 Do not connect.
9 GND 9 Ground. This ground is reserved for use with the ground
from your power supply.
10 Reserved 10 Do not connect.
11, 23 PWR 11, 23 Power provided to your Matrox Iris GT. The power must be
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 Reserved 12 Do not connect.
13 RxD_RS232 13 RS-232 receive.
14 AUX(USER)_O 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 AUX(USER)_O 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 TRIG_OPTO_IN0- 16 Opto-isolated trigger input signal, negative.
Note that, in TTL format this pin must be connected to
ground.
17 Reserved 17 Do not connect.
18 AUX(STB)_OPENC_OUT5 18 Open-collector auxiliary signal 5 (output).
Supported function: User-defined signal 5 (output).
19 AUX(USER)_OPENC_OUT7 19 Open-collector auxiliary signal 7 (output).
Supported function: User-defined signal 7 (output).
20, 21, 22, 24 Reserved 20, 21, 22, 24 Do not connect.
