Electrical Interfaces—EIA/TIA-232 and ITU-TS V.35
Caution
Ensure that the electrical interfaces of the equipment you connect to the modem
are compatible. Incompatible interfaces may seriously damage the modem.
Raymar-Telenetics makes no guarantee of the equipment’s integrity if you do not
ensure that compatible interfaces are used. If your DTE has a different interface,
you will need an external converter cable.
326X Series Modems have an EIA/TIA-232/EIA/TIA-562 electrical interface for
connection to external equipment. For compatibility with DTEs that have a V.35
interface, the V.34-SDC Modem is also available with the optional ITU-TS V.35
Recommendation electrical interface.
The rear-panel DTE port is configured at the factory for either interface.
Both interfaces
are not available in a unit.
Regardless of the interface, external DTEs are connected
through the modem’s rear-panel DTE port.
NOTE:
When operating with the V.35 interface, DIP switch S1 must be set to the off
(up) position (see Figure 2-2 or 2-3).
To purchase a compatible cable, consult Appendix B.
