P2 Slave support. V1.50 adds the ability to control the SX-1
from
an external device using
the P2 protocol. This is a large feature, and is fully described below.
P2 Slave
The SX-1 can re-use the RS422 port for P2 Master or P2 Slave. To set up P2 Slave, use the
LCD Transport / Machine Control List page.
z
First make sure there is no P2 Master or other RS422 device already in the list.
z
If so, use the DELETE LAST menu until there is no “422” entry in the list.
z
Select ADD, select RS422 in the submenu and turn the 4
th
encoder until P2 SLAVE is
highlighted in the menu.
z
Press OK
z
Make sure that the SX-1 HDR entry has CHASE=LTC Master set.
It is still possible to control the SX-1 if it is set to chase LTC or MTC, in which case motion
control commands will be translated and sent to the designated timecode master, if one is in
the machine control list, and just EDIT ON/OFF & Arming commands will be available.
Note: The RS422 port on the SX-1 is pre-wired to be a Master (Controlling Device). When
using the SX-1 as a P2 Slave, it is necessary to provide a cross-over connection to make the
SX-1 look like a Controlled Device.
