You can establish RS-485 connection with any GV-Readers. GV-CS1320 can connect with up
to
2 readers
. You need two power wires and two RS-485 wires from one reader to
GV-CS1320. When connecting a second reader to GV-CS1320, you will need to set up a
separate power source to power the second reader if the total power consumption (including
output devices) exceeds 12V.
