Eicon Networks 1530 manual SET Port Encoding NRZ Nrzi FM0 FM1

SET PORT ENCODING {NRZ NRZI FM0 FM1 }

Defines the type of data encoding used on the VHSI port. This setting must match that of the remote system.

NRZ: Enable Non Return to Zero encoding. Can be used for internal or external clocking.

NRZI: Enable Non Return to Zero Inverted encoding. Can be used with internal or external clocking, and INT-DPLL (Internal Digital Phase Lock Loop) or EXT-DPLL (External Digital Phase Lock Loop) with a line speed limit of 19,200 bps.

FM0: Enable FM0 (also known as biphase space) encoding. Can only be used with INT-DPLL clocking with a speed limit of 38,400 bps.

FM1: Enable FM1 (also known as biphase mark) encoding. Can only be used with INT-DPLL clocking with a speed limit of 38,400 bps.

SET PORT SPEED Speed

Defines the speed at which the VHSI port operates, in bits per second (bps). Certain restrictions inherent to the network to which the Eicon 1530 is connected can limit throughput. Speeds in excess of 128 kbps are possible on dedicated lines, but public X.25 data networks may be as slow as 2400 bps.

This parameter is used only when SET PORT CLOCKING is set to INTERNAL or INTDPLL. When external clocking is selected, the device providing the clock sets the line speed.

SET PORT INTERFACE {AUTODETECT RS232 V35 }

Defines the VHSI port interface. The VHSI interface supports RS-232 (V.24) and V.35. Specify AUTODETECT to have the Eicon 1530 detect the type of interface automatically.

SET PORT XT3 XT3Delay

Defines the DCD(off) -> RTS(on) delay. This is the delay before the remote is allowed to send at the end of reception. This parameter is intended for non-standard physical interfaces, and is for half-duplex lines only.

Range: 0-9999 milliseconds.

Default: 0 (disabled).

SET PORT XT5 TXIdleTimeout

Defines the Tx Idle Timeout. When the transmitter finishes sending a frame, it starts the Tx Idle Timer. If this timer expires before another frame is available for sending, the transmitter is turned off. This parameter is only used in half-duplex mode.

Range: 0-9999 milliseconds.

Default: 0 (disabled).

SET PORT XT6 XT6Maximum

Defines the RTS(on) -> RTS(off) maximum delay. This is the amount of time the transmitter may be active before turning the line around. This parameter is for half-duplex lines only.

Range: 0-9999 milliseconds.

Default: 0 (disabled).
