RS232 Control
One standard serial RS232 control panel port is provided:
à
RS232 used by the Attaché Control Panel to communicate with the
Attaché main chassis.
■
General Purpose Interface (GPI) Control
The GPI port provides simple “trigger” control over external devices, and allows
external devices to trigger macro functions within the Attaché. Control is
achieved by either cold contact closure from a relay, or by means of an electrical
“pull-up”. Four GPI inputs and four GPI outputs are standard:
à
The four GPI inputs are hard-wired to trigger the first four user-
programmable macro registers, macro-1 through macro-4.
à
The four GPI outputs are used to trigger external devices, and may be
activated either manually by using the Attaché Control Panel, or may be
programmed as a step in a user macro.
■
Ethernet Port
The Ethernet port permits external control over the basic transport functions of the
Attaché, and also supports audio and video transfers. Utilizing TCP/IP protocols,
the Attaché becomes an Internet node after specifying an Internet address.
Remote Shell (“rsh”) or Remote Login (“rlogin”) are available to provide
transport control. A variety of commands may be used to allow network image
file transfers to and from the Attaché in the form of video fields or frames. Please
refer to Chapter 5: Ethernet Operations, for a list of Ethernet commands.
Refer to Appendix A: Hardware Installation for details on all chassis connectors.
