6.1.2. Defining Hunt Groups

 

A Hunt Group creates a situation where the APS-16 will scan a group of ports and connect to the first available port in the group. Hunt Groups are created by assigning identical or similar names to two or more ports. Hunt Groups can be defined using Any-to-Any Mode, Passive Mode, Buffer Mode, or Modem Mode Ports.

1                     Access the Command Mode.

2                     Invoke the /P command to access the Port Configuration Menu for the desired Port(s). For example, to configure Port 4, type /P 4 [Enter].

3                     From the Port Configuration Menu, select item 1. to define the Port Name.

4                     Repeat steps 2 and 3 above to assign identical names to the other ports in the Hunt Group. For example, a series of ports in a group could all be named "PRINTER".

 

 

1                     To connect to the next available port in the hunt group, invoke the /C command using the port name to specify the desired group. For example, /C PRINTER [Enter].

2                     Your port will be connected to the first available port in the group. If all ports are presently connected, the APS-16 will respond with the "BUSY" message.

3                     It is only necessary to enter enough letters of the port name to differentiate the Hunt Group ports from other ports. Type an asterisk (*) to represent the remaining characters in the port name. For example, to connect your resident port to the first available port in a group of ports named "SALES1", "SALES2", and "SALES3", the connect command can be invoked as /C S* [Enter], providing no other port names begin with the letter "S".

 

Hunt Group port names must be unique. Otherwise, ports with similar names will also be included in the Hunt Group.

Hunt Group Example 1:

1                     Ports 1 and 2 are Modem Mode ports, and modems are installed at both ports. Port 1 is named "MODEM1" and Port 2 is named "MODEM2".

2                     Your resident port is Port 4. To connect to the first available Modem, access the Command Mode and type /C MODEM* [Enter].

 

Hunt Group Example 2:

1                     Ports 3, 4, and 5 are Any-to-Any Mode ports and printers are attached to each port. All three ports are named "PRINTER".

2                     Your resident port is Port 1, and you want to connect Port 2 to the first available printer, access the Command Mode and type /C 2 PRINTER [Enter].
