CONNECTING A DPG
DPG Master/Slave configuration

After the sweep is complete, the Slave DPG sends a status message to the Master
DPG which relays it to the SN388 HCI. That status is like those usually returned by
DSDs, with an extra specific code (26) if the Slave acquisition system fails to start.
That type of error can be detected by monitoring the RDYIN signal, low during
acquisition, high otherwise (pins P and R of the RECORDER connector).
By connecting an RS232 line between the COM2 connector on the Slave DPG and
the Station Unit on the Auxiliary line, via an XDEV adapter, an ASCII message can be
transmitted to the Slave recording system to identify the shot in progress. The format
of the message is as follows:
*VE432/SL
#
xxxx,x/SN
#
xxxx,x/SI
#
x
<CR><LF>
SL Source Line
SN Source Number
SI Source Index
