PC RS-232 Serial Port to External Sony P2 RS-422 Controller
The RS-232 ports of a standard PC are slightly different from the RS-422 format used for the Sony P2 protocol. We
recommend the use of an external RS-232/RS-422 adapter. One example is the
Antona ANC 6090 which can be
ordered from your Merging sales representative under the item number
MRS422. This adapter is intended to be
connected directly to the serial port of your PC (either COM1 or COM2) with the other end used to connect a stan-
dard Sony P2 RS-422 cable. As both connectors on the adapter are Female DB9, beware of the orientation and
please check that the printed indication "RS-232" is connected to the PC COM port.
Connecting an RS422 device using a direct cable
(without RS-232 / RS-422 adapter)
For emergency use and for short distances, a direct cable may be used. However, Merging Technologies does not
guarantee the correct function of an external controller if this cable is used. Different cables are required depend-
ing on whether Pyramix is controlled by a master device or is controlling a slave device.
Direct Cable for a Master Device
This pinout should work in most of the cases where Pyramix is controlled by a Master device (check on your con-
troller if the RS422 connector has to be male or female). It has been tested with various mixers such as Sony DMX-
R100, Soundcraft Spirit, Soundtracs DPC II and DS3, and various other Sony P2 protocol capable controllers:
The RS422 standard is not implemented consistently on all devices, so the cable pinouts may differ. Please consult
your controller's user guide for appropriate connector cabling.
