Chapter 5 - PASHA
50 Version 1.7.2.0 March 27, 2015
.
Introduction
PASHA, the MediaMatrix Serial Handling Adapter, is a remote control protocol that provides
external serial control and read-back of any of the controls appearing in an NWare project.
Notes:
 By default, console mode on the NION RS-232 serial port is disabled. In order to use
PASHA on this port, it must remain disabled. For more information on configuring the
port, refer to the section Specifying the function of the RS-232 serial port in the NION
Hardware Manual.
 You cannot specify PASHA for one serial port on a NION and RATC for the other serial
port. However, you can specify different variants of PASHA on the two serial ports; for
example, PASHA/Legacy and PASHA/X-Control.
Allowing PASHA to be used on a MediaMatrix node
1. Right-click the NioNode, nControl node or nTouch 180 node, and then click Device
Properties.
2. In the Serial Control Protocol list, click a PASHA option.
PASHA/PageMatrix
Protocol used with the PageMatrix Command Center. It supports a
four character control ID sent with the (T) trigger command.
PASHA/XControl
Provides basic S (Set) PASHA functionality with X-Net2-style trigger
commands.
PASHA/Legacy
Designed for projects that contain legacy MediaMatrix nodes that are
controlled by external programs using the classic PASHA protocol, as
implemented on MainFrames and MiniFrames. When you want to
replace the legacy nodes with NioNodes, select the PASHA/Legacy
option and you will not need to update your external program code.
This option ensures all hex values are returned from nodes in lower
case instead of upper case to match the original MediaMatrix PASHA
protocol.
