The Interface Commands
6.1.7.1
ASI Interface Commands
The ASI interface is fitted on all AMT70 modem on the demodulator card. The TDATA / RDATA
commands control the data rate for this interface.
6.1.7.2
RS530 + 1*HSSI interface
The commands associated with the RS530+HSSI interface card are as follows:

: RS530 + 1*HSSI Commands Summary
Interface
Commands
ifmode
The modem supports two interface modes; RS485 or single HSSI.
For modems equipped with the router option, an extra mode is supported:
ETHERNET
iftxclock
Set the interface transmit clock mode.
The selections are; INTERNAL | EXTERNAL | RXLOOP | RS530TFD.
ifttinv
Control the edge of data interface transmit clock signal that registers the data (TT).
This signal can be inverted for compatibility with some OEM equipments;
ON | OFF.
iftdinv
Control the TX data inversion; ON | OFF.
ifrxclk
Control the selection of RX data receive clock; LOCAL, DTE_TT or DEMOD
ifrtedgeinv
Control the transmit clock inversion mode; ON | OFF
iftdinv
Control the RX data inversion; ON | OFF
ifbufmode
Control the Doppler buffer algorithm; in AUTO mode the buffer size is controlled
by internal algorithms. In MANUAL mode the buffer can be set statically.
ifbufsize
Set the buffer size when the buffer mode MANUAL is selected.
ifbufmon
Display the current Doppler buffer usage.
ifbufreset
Reset (realign) the receive Doppler buffer on the card
ifloopmode
Set the data interface loopback mode.
The selections are;
LINELOCAL, LINEFAR, SYSTEMLOCAL, SYSTEMFAR
On this interface the data rate are set by the TDATA / RDATA commands.
For more details about all these commands refer to the sections 6 at page 51.
