Connecting RS-232 Cables: Daisy-Chain Connection
After mounting each display, insert any cables used for Power, video inputs or outputs into the set.
Prior to mounting the next display, insert cables (including RS-232) from the outputs of the first display into the inputs of the second display.
Repeat above steps for next display, if necessary.
The RS-232 daisy chain limitation is listed as 20 displays, although theoretically more units can be accommodated. 25 displays was the
maximum number of units tested during production. While GPO Display can make no guarantees, RS-232 daisy-chaining should be able to take
place on up to 25 displays.
Daisy-chaining can be initiated from any unit but
it is strongly recommended that you start with a display on the bottom row
for ease of
access. There is no terminator at the end of the unit. It is always recommended to record/make note of the chaining diagram as it is crucial to
determining issues with communication.
