DEMI sequencer - old version connections?
I picked up a used DEMI TRS sequencer and downloaded
the manual from the DEMI website. However, I must
have an older version, as the markings on the back
connections are largely different. My connections
are: +13v, PTT, TTL, NO1, NO2, NC1, NC2, TR, RX, TX1,
I checked the connections with a meter and determined
that NO1, NC1, and TX1 are grounded when the PTT is
engaged. NO2, NC2, and TX2 produce 13v when the PTT
is engaged. TR shows 13v when PTT is not engaged and
0v when PTT is engaged. RX is at ground when PTT not
engaged, open when engaged. TTL has a cap on the
connector and I left it on.
I am just trying to protect a mast-mounted preamp from
being fried by my 500w amp. Based on the above
readings, my thinking is that TR goes to the preamp's
13v connection and that TX1 goes to the amp keying
Does that sound right? Does anyone happen to have the
manual for this older version?
Thanks and 73,
