The R220PL_ZRS RS-232 Relayy will connect to any computer or device through a DB-9 or direct wire connection that has the ability to
send numerical commands. The board will mount to any existing COM port for computer connections and connect to other devices through
an RS-232 connection. Add relay control to Crestron, AMX or any system that has a DB9 interface where you need to control a relay!
R220PL_ZRS The Ideal Choice
The R220PL_ZRS RS-232 Relay allows you to program in almost any language and has the ProXR Command Set, the industry leading command set
for controlling the relay and reading the inputs on the board. Commands can be as simple as turning on/off each relay individually and as complex as
adding delays and other features to the command such as flashers, grouping relays, and controlling banks of relays at once.
