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.
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.
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.
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.
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.
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.
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.
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.
may be active before turning the line around. This parameter is for half-duplex lines only.
Range: 0-9999 milliseconds.
Default: 0 (disabled).
