IR/Serial Connections and Wiring
You can connect up to eight IR- or Serial-controllable devices to the IR/Serial connectors on the
rear of the NI-4000 and NI-3000 and up to four on the NI-2000 (FIG. 16). These connectors accept
an IR emitter (CC-NIRC) that mounts onto the device's IR window, or a mini-plug (CC-NSER) that
connects to the device's control jack. You can also connect a data 0 - 5 VDC device. These units
come with two CC-NIRC IR emitters (FG10-000-11).
The IR/Serial connector wiring specifications are listed in the following table.
