S.I Tech Model 9308 multiplexer Bit-Driver is designed to work with IBM System 3/X, AS/400 and
5251 controller using twinax cable. Model 9308 Bit-Driver is an 8 channel twinax to fiber optic transmitter/receiver
full duplex multiplexer product implementing IBM Protocol. Normal operating data rate is 1 Mbps on each port.
This fiber optic Bit-Driver product eliminates many disadvantages of twinax, especially EMI/RFI, ground loops (electrical
isolation with fiber), high attenuation (high signal loss). limiting distance between nodes of system (5000feet
max twinax), and potenial lightning damage outdoors between buildings.
S.I.Tech Model 9308 is a stand alone product allowing easy change from twinax to fiber: Simply disconnect twinax
cables and connect to model 9308 input/output port. Model 9308 comes with power supply and status indicators.
NOTES:
S.I.Tech multiplexer can support one controller (one card from IBM 3/X andAS/400). IBM machines come with a various
number of ports per controller. Check IBM equipment manuals for details. The number of ports is not fixed. While
seven devices are supported per any given port, the total devices the controller card can support does not equal
7 x number of ports, e.g. System 36 has options such as:
First: 6 devices - one controller card.
Second: 28 or 36 devices - one controller card.
Third: 72 devices - second controller card. System 38 controller supports 32 devices.
Total 400 with 10 controller cards. AS/400 controller supports 40 devices. Total 400 with 10 controller cards.
S.I.Tech 9308 can support 32, 36 and 40 devices as long as only one controller card is connected to 9308 ports.
S.I.Tech Model 9308 is totally transparent and uses IBM Protocol and addressing. If other than twinax cable is used,
impedance matching transformers (balun) are needed.
