Frequently Asked Questions - HUB 4000 AKG

How to connect the HUB 4000 to a computer?

Use a crossover Ethernet cable for a direct connection. If using an Ethernet hub, use a straight-through cable. Connect the cable to the PC LINK (RJ45) connector on the hub and to the network card of the computer.

How to assign an IP address to the HUB 4000?

Remove the cover plate over the ADR switches. Set the four DIP switches according to the table in the manual to obtain the desired IP address (e.g., 1111 for 192.168.0.4). Make sure this address is not already in use on the network. Turn the hub off and on to activate the new address.

Can I use multiple HUB 4000 together?

Yes, you can daisy chain multiple HUB 4000 using standard Ethernet hubs. Assign consecutive IP addresses to each hub (in increasing order) to ensure proper operation with the MCS 4000 software.

What does the blinking of the blue DATA TRANSFER LEDs mean?

A blue LED that blinks indicates data exchange between the HUB 4000 and the connected SR 4000 receiver. Slow blinking (about every 3 seconds) signals a communication problem (faulty cable, hardware or software defect). An LED off means no receiver is connected or the connection is broken.

What type of cable to use for SR 4000 receivers?

Use exclusively the cables supplied with RJ11 connectors. Connect each receiver to one of the RECEIVER DATA SR 1 to SR 8 ports on the rear of the HUB 4000.

The HUB 4000 does not power on, what to do?

Check that the power adapter is properly connected to the 12 V/500 mA connector on the hub and to a suitable mains outlet. Ensure the mains voltage matches that indicated on the power adapter. If the problem persists, contact AKG customer service.

How to clean the HUB 4000?

First disconnect the power adapter. Use a slightly damp cloth (not wet) with water. Never use abrasive products, alcohol, or solvents that could damage the paint and plastics.

Can I open the HUB 4000 to repair it?

No. The device contains no user-serviceable parts. Any intervention must be carried out by authorized AKG technical personnel. In case of issues, contact customer service.

Which software to use to control the HUB 4000?

You must use the optional MCS 4000 software, compatible with Mac OS, Windows, and Linux. It allows managing all hubs and connected receivers. For exact system requirements, refer to the software manual.

How to test if the HUB 4000 responds on the network?

From the computer, use the ping command with the hub's IP address (e.g., ping 192.168.0.4). If the hub responds, the network connection is established. If not, check the cables, IP address, and network configuration of the computer.

3.2 Assigning IP Addresses

Refer to fig. 6.

Each unit within the network needs its own, unambiguous IP address.
- The IP address of each HUB 4000 is factory-set to 192.168.0.4. The related combination of the ADR DIP switches is "1111".

Important!

Before connecting the unit to power, check that the IP address (ADR combination) of the unit is not identical to any other IP address previously assigned within the network. IP addresses assigned to multiple units may cause data transmission problems.

Important!

If you daisy-chain several HUB 4000s, remember to assign to the hubs consecutive IP addresses in ascending order to make sure the computer will correctly identify and control all HUB 4000s.

Refer to Table 1.

• You may assign any IP address between 192.168.0.4 and 192.168.0.19 to the HUB 4000 directly connected to the computer (hub no. 1). Assign the next higher IP address to the next HUB 4000 in your chain referring to Table 1. Enter the selected IP address of the first HUB 4000 in the MCS 4000 control program to enable the program to control the hubs correctly.

Table 1: IP addresses for 16 hubs.

Hub no.	ADR switch positions		IP address
	0..down	1...up
1	1111		192.168.0.4
2	1110		192.168.0.5
