General Description:
The IBS485 "SPIDER" is an automatic repeater that expands an RS-485 serial communication
network by increasing its maximum distance and number of nodes. The repeater
connects FIVE RS-485 lines and transfers data in both directions on each line.
On receiving data from one line, the repeater automatically regenerates and
retransmits the data on the other lines. Data is transferred at the bit level
so all formats are supported and with nearly no delays. Each of the 5 lines
has it's own set of control jumpers that can be used to manually enable it's
RX and/or TX capabilities, adjust the bias and add termination. Protection for
the overall network is provided through isolation on each of the lines. All
the repeater lines and controller circuitry can be powered by a single supply
with an output in the range of 9 to 35VDC at 5 watts max.
