Overview

The 5901 modem provides high-speed dial-up telephone communication for SCADAPack, TeleSAFE Micro16 and SmartWIRE controllers. The 5901 modem is a 5000 Series module and may be fully integrated into a DIN rail mounted controller system. Operating power is received from the I/O Bus and the 5901 modem requires no external power source.

The 5901 modem supports telephone line connection speeds up to 56k baud. The 5901 modem performs complete handshake and data rate negotiations and supports error correction and data compression modes to ensure data transfer integrity. Non-error correcting mode is also supported. The 5901 modem supports DTE speeds up to 115200 baud with speed buffering at all speeds. XON/XOFF or RTS/CTS flow control between DTE and 5901 modem are supported.

Auto-recovery circuitry in the 5901 modem ensures controlled modem operation at all times. The 5901 modem is reset to the factory default or user-defined settings whenever power is applied or when the modem receives an I/O Bus Reset signal from the controller. A modem reset may be performed using the modem control functions in TelePACE Ladder Logic and C Tools programs. The 5901 may also be reset from a remote location using a pre-defined dial sequence.

The 5901 modem supports the Hayes "AT" command set. The 5901 modem automatically determines the speed and format of the data sent from the DTE. Under AT operation the modem performs an autobaud/autoparity/autolength function on each AT command entered.

Telephone line protection consists of a three-electrode spark gap surge arrester from TIP and RING to chassis and a MOV from TIP to RING. The 5901 modem operates in environmental conditions of between - 40°C and +70°C and between 5% and 95% relative humidity.
