3 Fiber Optic Converter Overview
3.3 CON/FO/TTL
The fiber optic module CON/FO/TTL converts a FO
(fiber optical) input signal into one or more electrical
output signals (TTL or RS-422).

CON/FO/TTL
FO to TTL Converter
The following options are possible:
1.)
CON/FO/TTL: two TTL outputs via BNC con-
nector
2.) CON/FO/422: one RS422 output via 9pin-DSub
connector
3.) CON/FO/TTL/422: one TTL output (BNC) and one
RS422 output (DSub)
