Input signals
Amplitude modulated IRIG-A/B or AFNOR codes must be connected to the BNC-
jack in the bracket of TCR170PEX. A shielded or a twisted pair cable should be used.
Pulse width modulated (DC Level Shift) signals are applied by using the D-Sub-
plug. Two DIP-switches must be set to the ‘ON’ position for connecting the contacts
of the D-Sub with the onboard photocoupler.
As an option, an optical input can be equipped instead of the modulated input. It is
available as ST-connector for GI 50/125µm or GI 62,5/125µm gradient fiber.
The IRIG code used must be configured with the monitor software.
The board TCR170PEX can’t be used to decode amplitude modu-
lated and DC Level Shift signals simultaneously. Depending on the
selected code, only the signal at the BNC-jack, the D-Sub or the
optional optical input connector is decoded.
