Response to Query

Engineering

Channel

ESC=

1 byte, 0 or 1

Command or Query. (IBS and ESC++ feature)

Sets or returns ESC in the form x, where:

0=Disable the high-rate ESC

1=Enable the high-rate ESC

Note: IBS ESC may only be enabled when:

1) Both Tx and Rx framing modes are set to IBS.

2) Data rate is not 1544 kbps (as spare overhead bits are not available in this mode).

3) IBS high-rate ESC FAST option is enabled.

Parameters

SCP=

Exception –

600/L Emulation:

SCP=xy

3 bytes, numeric Command or Query. (IBS and ESC++ feature)

Sets or returns the ESC baud rate and character format in the form xyz, where:

x=index for baud rate:

0=1200 baud

1=2400 baud

2=4800 baud

3=9600 baud

4=19200 baud

5=38400 baud

6=14400 baud

7=28800 baud

y=character format (data bits, parity, stop bits):

0=8N1 char format

1=7E2 char format

2=7O2 char format

z=interface type:

0=RS-232

1=RS-485

Note: The baud rate may be limited by the data rate. The ESC baud rate breakpoints (determined by data rate)

are shown in Chapter 6 and Appendix J. A response of SCP* indicates that the data rate will not allow a selected

baud rate to operate.

EDMAC

Framing Mode

EFM=

1 byte, 0 or 1

Command or Query.

Sets or returns EDMAC mode in the form x, where:

0=EDMAC OFF (Idle Mode)

1=EDMAC ON (Master Mode)

2=EDMAC ON (Slave Mode, Query Only)

EDMAC Slave

Address Range

ESA=

4 bytes

Command or Query.

Sets or returns EDMAC range of addresses of distant-end units (modems or transceivers) for which this unit, as the

Master, will forward messages. Only values which are integer multiples of ten are permitted. (0010, 0020, 0030, 0040

etc.)

Example: <0/ESA=0090

Note: This command is only valid for an EDMAC master. When used as a Query, it may be sent to an EDMAC slave,

which will respond with the appropriate address.
