Hi guys Im trying to install a used pelco spectra but im trying to work out how to wire its ptz to my dvrs rs485
Its been wired for ptz before in its previous install but from what i can see the existing wiring (basically at cat 5) only seems to go into the alarms , ground and relays com ports nothing as far as i can see for the ptz control?
Im i right in saying its ptz control goes into the rx + and - or tx + and - as nothing seems to have been wired into these in its previous install?
CONNECTIONS AVAILABLE ARE
Alarms 1 through to 7
Relays - GND COM NC AUX AND GND
RX+ AND RX-
TX + AND TX -
I also have loads of dip switches but i come to those later after ive worked out where to wire the two rs485 wires to.
