3.2 CON/TTL/FO
The fiber optic module CON/TTL/FO converts an input
signal (TTL, RS422 or FO) into one or more FO (fiber
optical) output signals.
CON/TTL/FO-4
V2
CON/TTL/FO
TTL to FO Converter
The following options are possible:
1.) CON/TTL/FO: TTL input via BNC connector to
one FO output
2.) CON/TTL/FO-x: TTL input (BNC) to x (2, 3 or 4)
FO outputs
3.) CON/422/FO: RS422 input via 9pin-DSub connec-
tor to one FO output
4.) CON/422/FO-x: RS422 input (DSub) to x (2, 3 or
4) FO outputs
5.) CON/FO/FO-x: FO input (ST) to x (2, 3 or 4) FO
outputs
