8. Operation 8.1. Any-to-Any Mode Any-to-Any Mode Ports can be connected to other Any-to-Any, Passive, Buffer, or Modem Mode Ports by accessing Command Mode and issuing the /C Command. All ports can be configured for the Any-to-Any Mode. 8.1.1. Port Connection and Disconnection The APS provides communication between devices without the requirement that both devices use the same communication parameters. This allows you to connect devices that use dissimilar baud rates, parity, handshake, and etc.
APS-8M User’s Guide To Connect ports, proceed as follows: 1. Access the Command Mode as described in Section 5.1. If the Password Prompt is displayed, enter your Supervisor Password or Port Password. 2. Invoke the /C command to connect the desired ports. a) Resident Connect: To connect your resident port to another port, type /C xx [Enter]. Where xx is the number or name of the port you want to connect.
Operation 8.1.1.2. Disconnecting Ports There are three different methods for disconnecting ports, the Resident Disconnect, the Third Party Disconnect, and the No Activity Timeout. Providing the Timeout feature is enabled, a No Activity Timeout will disconnect resident ports or third party ports. Note: When Any-to-Any Mode, Buffer Mode, or Passive Mode are selected, Option 74 in the Port Parameters Menu determines how the DTR signal will react when the port disconnects.
APS-8M User’s Guide 2. Third Party Disconnect: (Supervisor Mode Only) The /D command is issued from your resident port to disconnect two third party ports. For example, if your Resident Port is Port 1, a Third Party Disconnect would be used to disconnect Port 3 from Port 4. a) The /D command uses the format: /D xx XX [Enter], where xx and XX are the numbers of the ports that you wish to disconnect. b) The /D (Disconnect) command can only be invoked by a port with access to Supervisor Level commands.
Operation 8.1.2. Defining Hunt Groups A Hunt Group creates a situation where the APS 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, Passive, Buffer, or Modem Mode Ports. 1. Access the Command Mode. If the password prompt is displayed, enter the Supervisor Password. 2.
APS-8M User’s Guide 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 configured as Modem Mode ports, and external 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 external Modem, access the Command Mode and type /C MODEM* [Enter]. Hunt Group Example 2: 1.
Operation 8.3. Buffer Mode Ports configured as Buffer Mode ports will collect data from the connected device and store it in the APS's statically allocated memory. Each APS port features a fixed length, fixed position data buffer. The Buffer Mode allows collection of data from various devices without the requirement that all devices use the same communication parameters (e.g. baud rate, parity, etc.). Notes: · Buffer Mode Ports cannot access the Command Mode.
APS-8M User’s Guide If the port's buffer is empty, the APS will send a message which reads "Connected xx, Buffer Empty"; where "xx" is the port number. If the buffer contains data, the APS will display a prompt that offers four options: · Next Screen: To scroll through data one screen at a time, press the [Space] bar. Each time the space bar is pressed, the next full screen of data will be sent. · Scroll All: To send all data without pausing, press [1].
Operation 8.4. Modem Mode In addition to allowing data transfer, the Modem Mode also provides additional functions specifically related to modem communication. A Modem Mode Port can perform all functions normally available in Any-to-Any Mode. The Modem Mode is available to all APS RS232 ports. In addition to allowing configuration of the APS-8M's internal modem, the Modem Mode also simplifies the process of connecting an external modem to Ports one through seven.
