Hardware
1 ASY Serial Port: Provides an additional asynchronous RS232 serial port using a DB25 connector.
2 ASY Serial Port (3x): Provides three additional asynchronous RS232 serial ports using RJ45
connectors.
3 SYN/ASYN Serial Port: Provides an X.21/RS422/RS232 synchronous / asynchronous serial port
using a DB25 connector.
4 GPS: Provides GPS capabilities using an SMA male connector.
5 ISDN: Provides an ISDN Basic Rate Interface (BRI) via an RJ45 port. This can be configured either
as a TE (terminal endpoint) or as NT-1 (network termination). The option also includes an
additional asynchronous serial port via a second RJ45 port.
6 Telemetry 1 I/O Interface: Provides 4 opto-isolated digital input ports and 1 opto-isolated
digital output port. It also provides a relay I/O port, a voltage monitoring port, and internal
temperature monitoring.
7 Telemetry 2 I/O Interface: Provides 4 isolated analog I/O ports and 4 non-isolated digital I/O
ports.
8 Fleet I/O Interface: Provides a CAN and J1708 interface, GPS, 4 non-isolated digital I/O ports,
ignition sense port, and a 3-axis accelerometer.
9 PSTN: Provides a PSTN interface via an RJ45 connector for dialing out and receiving calls.
10 ISDN-U/PSTN: Provides an ISDN-U interface suitable for the USA plus PSTN interface. It can be
configured for Bell-103 modulation in leased line mode as well as a normal PSTN interface.
11 DialServ: This RJ11/FXS connection converts a PSTN analog modem to a RS-232 serial signal.
For more information on the Telemetry 1 Interface, Telemetry 2 Interface, and the Fleet I/O
Interface, see the product specific user's guides, available on
