7. Application NotesThe optical fiber input/output links operate
at 3.3 Mbps. Fiber-optic channel 0 is compatible with theSM64 IO
interface (iba Order #1.300).
The following components are compatible with fiber-optic channel
0 of the SM128V
SM 64 IO (peer-to-peer operation of SM64 IO and SM128V is NOT
supported)

The following devices are compatible with fiber-optic channel 1
of the SM128V
Padu8-0
FOB 4i PCI and FOB x/4-F
FOB 2/2-IO (receive ports only)
FOx3
FOB-0F Link
Both fiber-optic output channels (Chan 0 and Chan 1) can be
interfaced to individual iba PCMCIA-Fcards via the X4 and X5 RJ11
sockets. Note that only one PCMCIA-F card may be used at a time in
aNotebook measurement PC.

8.1.1 Fiber-Optic Connectors X1 and X2
Channel 0 communicates bi-directionally with compatible devices
over the X1 and X2 interface ports.Both ports use standard ST type
connectors. X1 realizes the fiber-optic transmitter while X2
realizesthe fiber-optic receiver.
8.1.2 Fiber-Optic Connector X3
Channel 1 communicates unidirectionally with compatible devices
via the X3 interface port. This portuses a standard ST type
connector. X3 realizes the fiber-optic transmitter for Channel
1.
8.1.3 RJ11 Connector X4
Channel 0 may transmit data unidirectionally to a single iba
PCMCIA-F device via the X4 interfaceport. This port uses a special
serial cable that is delivered with the PCMCIA-F. Data is
transmittedsynchronously with port X1.
