RS-232 and RS-422 Cabling
007-4403-003 99
The following example shows the control-in.conf file for a Horita PR-232
connected to serial port 3:
hsip rs232 3 9600 0 1 29.97
This example shows a Miranda Little Red in a 625/50 configuration:
little-red rs232 3 9600 0 1 25
4. Add a line for each device to control-in.conf to configure the SGI Media Server
to work with Horita and the Miranda Little Red timecode readers. The following is
an example:
hsip rs232 3 9600 0 1 29.97
little-red rs232 2 9600 0 1 29.97
The format of the configuration line is explained in “Configuring the SGI Media
Server for Control by Remote Devices” on page 47.
5. The vtr.time.offset control specifies the offset (in nanoseconds) between the
actual timebase and the decoded input timecode. This offset accounts for delays in
the timecode reader, in the serial communications with VST, and in VST time
processing. Use the SSET command to change the value, or set this value in
/usr/vtr/config/system-defaults/main. The following is an example for
the Little Red:
SSET main vtr.time.offset -27000000
See http://www.miranda.com/pdf/manual for documentation on the Little Red
device and http://www.horita.com for information on the PR-232.
RS-232 and RS-422 Cabling
This section gives an overview of cabling an RS-422 connector between a Harris
Automation controller and the XIO DB-9 connector on the SGI Media Server. Figure 7-1
shows the pinouts for the RS-232 and RS-422 protocols.
