Port Configuration - AMX Modula Instruction Manual

Port Configuration

The configuration of the X-Port and Y-Port connectors must match the port configuration of the
controller and device equipment attached to the Modula.
Determine and Set Switch Settings
The toggle switches individually configure the X-Port and Y-Port connectors to function as controller or
device ports. The switches are above and to the left of the DB-9 connectors (FIG. 98), which support the
®
Sony 9-pin RS-422 pinout. The default setting for X-Port connector switches is CTL for attaching
controller equipment. The default setting for Y-Port connector switches is DEV for attaching device
equipment.
If your system setup is different, the toggle switches on the boards must be adjusted accordingly.
If the equipment attached to a board functions as a controller, set the switch to CTL.
If the equipment functions as a device, set the switch to DEV (see pinout table on page 139).
Important: If the toggle switches are changed from their default settings, the control information
provided on page 143 through page 145 must also be interpreted accordingly.
To set the port configuration:
1.
Toggle the switch up for the device (DEV) setting or down for the controller (CTL) setting.
