Figure 2.30. Connecting Serial Communications via RS422
There are three RS422 ports on the projector—two are 6-pin XLR ports (rear of
projector) and the remaining is a 9-pin D-connector (side of projector). Use any of
these ports for communications to and from an RS422-compatible controller, and/or
as in-and-out ports for networking multiple projectors together on a serial network
(note there is no 9-pin “out” port).
NOTES: 1) Do not use the rear ports for downloading main software upgrades to the
projector—use the 9-pin side port only. 2) Upon power-up of an RS422 network, wait
until all projectors are initialized before sending further commands. Commands sent
during initializing will be lost.
CAUTION
Do not use an RS422 port unless you are using
equipment with RS422 capability. The voltage levels of
this signal can damage incompatible equipment.
