5.5.2.Port Modes

The APS-8/16M offers four different port operation modes; Any-to-Any Mode, Passive Mode, Buffer Mode, and Modem Mode. The Port Modes function as follows:

•Any-to-Any Mode: Allows communication between connected ports. Any-to-Any Mode Ports can be connected to other Any-to-Any, Passive, Buffer, or Modem Mode Ports by accessing command mode and invoking the /C command (see Section 8.1.1). The Any-to-Any Mode is available to all APS-8/16M ports, except the Internal Modem Port (The Internal Modem Port is Port 8 on the APS-8M, and Port 17 on the APS-16M.)

•Passive Mode: Allows communication between connected ports, but does not allow access to command mode. Passive Mode Ports can be connected by accessing command mode from a free Any-to-Any or Modem Mode port and invoking the /C command (see Section 8.1.1). The Passive Mode is not available to Ports 1 and 2, or the Internal Modem Port (The Internal Modem Port is Port 8 on the APS-8M, and Port 17 on the APS-16M.)

•Buffer Mode: Allows collection and storage of data received from connected devices. Collected data can be retrieved by accessing command mode from a free Any-to-Any or Modem Mode Port, and issuing the Connect Command (/C.) Note that the Buffer Mode also allows pass-through communication with the connected device. The Buffer Mode is not available to Ports 1 and 2, or the Internal Modem Port (The Internal Modem Port is Port 8 on the APS-8M, and Port 17 on the APS-16M.)

•Modem Mode: A Modem Mode port can perform all functions normally available in Any-to-Any Mode, but the Modem Mode also allows deﬁnition of a Hang-Up String, Reset String, and Initialization String. Any APS-8/16M RS232 port can be conﬁgured for Modem Mode, and the Internal Modem port is always conﬁgured for Modem Mode.

For more information on Port Modes, please refer to Section 8.
