Parameters
SCP=
Exception –
600/L
Emulation:
SCP=xy
3 bytes,
numeric
Command or Query. (IBS and ESC++ feature)
Allows control of the ESC baud rate and character format in the form xyz, where:
x is the 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 is the character format (data bits, parity, stop bits):
0=8N1 char format
1=7E2 char format
2=7O2 char format
z is the interface type:
0=RS-232
1=RS-485
The baud rate may be limited by the data rate. The ESC baud rate breakpoints (determined by data rate)
are shown in Chapter 5 and Chapter 12. A response of SCP* will indicate if the data rate will not allow a
selected baud rate to operate.

600L Emulation:
MRC=
1 byte, value of
0 thru 6
Command or Query.
External Frequency Reference in the form x, where:
0=Internal 10MHz (default)
1=External 1 MHz
2=External 2 MHz
3=External 5 MHz
4=External 10 MHz
5=spare
6=Internal 10MHz plus output.
This means that the Reference is available on the “Ext Ref” rear connector (small rear-panel LED
indicates when ON)
