6.
Control Network
RJ45 Gigabit Ethernet port. Connect a laptop, wireless router or switch to use with the
AHM-64 System Manager, IP remote controllers, Custom Control app or TCP control.
All devices on the network must have compatible IP addresses.
A recessed switch lets you reset the network settings to factory default. To reset,
turn the unit off, insert a pointed object to press and hold the switch whilst
turning the unit back on. Hold the switch in for at least 20 seconds.
7.
SLink
For connection to remote I/O expanders
with plug ‘n play operation. Supports the GX,
DX, AB and AR ranges of expanders plus the DX Hub. It can also be used for
connection to an Allen & Heath SQ, Avantis or dLive live mixing console, or linking to
another AHM-64 unit.
The Lnk/Err LED flashes yellow at a steady rate when the link is established, and lights
red if a communication error is detected.
8.
GPIO
General purpose interface for control integration with third party hardware. Offers 2x
inputs switching to ground, and 2x relay outputs on Phoenix connectors, in addition to
a +10V DC output.
Maximum current drawn from the +10V supply for all outputs combined must not
exceed 200mA
Output 1 can be wired as normally closed or normally open. Output 2 is normally
open.
For higher current or voltage applications, an external DC power supply may be used.
This also provides total isolation between the AHM-64 and external equipment.
Maximum external supply voltage must not 24V DC. Maximum current
sink through any open collector output must not exceed 400mA.
Use the provided 10-pin Phoenix connector with strain relief for optimal cable
management.
9.
Kensington lock
Slot for securing the unit or peripheral devices using industry standard Kensington
locks and cables.
