MBE MESSAGE (AUDIO) MODE SETTING
TERMINAL MODE RELATED
SUMMARY: 
Set expansion audio devices to be used in communication with the connecting 
CODECs (VL 5000s).
STEP PROCEDURE 
Note:
MCU 500A does not support MBE message (audio) mode.  Be sure, therefore, to set all the 
system parameters to OFF (00H 00H)
.  If change is necessary for any reason, follow the steps 
described below.
1 Enter the following command.
SSPR__ n1 =  x1 __n2 = x2 __ … ni = xi … ¿
ni:
System parameter address138H 
and 139H
[1] Addresses (hexadecimal values) on setting the MBE message (audio) mode.
The MBE message (audio) mode is set in hexadecimal values by dividing the 16 bits 
(b0 to b15) into the upper-half and lower-half 8 bits.

138H  Lower-half 8 bits setting address (b0 to b7)
139H Upper-half 8 bits setting address (b8 to b15)

MBE MESSAGE (LSD2) MODE SETTING
TERMINAL MODE RELATED
SUMMARY: 
Set expansion LSD (Low Speed Data) devices to be used in communication with 
the connecting CODECs (VL 5000s)
STEP PROCEDURE 
Note:  
MCU 5000A does not support LSD2.
1 Enter the following command.
SSPR__ n1 =  x1 __n2 = x2 __ … ni = xi … ¿
ni:
System parameter address13AH 
and 13BH
[1] Addresses (hexadecimal values) on setting the MBE message (LSD2) mode.
The MBE message (LSD2) mode is set in hexadecimal values by dividing the 16 bits 
(b0 to b15) into the upper-half and lower-half 8 bits, or specially by setting any of bit 
0, bit 2, or bit 3 in the lower-half 8 bits to “1” or “0”.  Accordingly, since the upper-
half 8 bits are always 00H
, set only the lower-half 8 bits (address 13AH).
ADDRESS MBE MESSAGE (LSD2) MODE
13AH  Lower-half 8 bits setting address (b0 to b7)
13BH Upper-half 8 bits setting address (b8 to b15)
xi:
System parameter values See  below:
[1] System parameter values on setting the MBE message (LSD2) mode for the 
addresses 13AH and 13BH.

MBE MESSAGE (VIDEO) MODE SETTING
TERMINAL MODE RELATED 
SUMMARY:
Set expansion video devices to be used in communication with the connecting   
CODECs (VL 5000s).
STEP PROCEDURE 
Note:
Set “PTY
” and “FULL
” to OFF
 as a general rule.  Set “VSP
” to ON
 when the dual screen 
multiplex function is used at the connecting terminals, and OFF
 when it is not used.
1 Enter the following command.
SSPR__ n1 =  x1 __n2 = x2 __ … ni = xi … ¿
ni:
System parameter address13CH 
and 13DH
[1] Addresses (hexadecimal values) on setting the MBE message (video) mode.
The MBE message (video) mode is set in hexadecimal values by dividing the 16 bits 
(b0 to b15) into the upper-half and lower-half 8 bits, or specifically by setting any of 
bit 1 through bit 3 in the lower-half 8 bits to “1” or “0”.  Accordingly, since the upper-
half 8 bits are always “00H”, set only the lower-half 8 bits (address 13CH).
ADDRESS MBE MESSAGE (VIDEO) MODE
13CH  Lower-half 8 bits setting address (b0 to b7)
13DH Upper-half 8 bits setting address (b8 to b15)
