MLP CAPABILITY SETTING
TERMINAL CAPABILITY RELATED
SUMMARY:
MCU 5000A communicates with terminals (VisuaLink ADs) via MLP channels.
STEP PROCEDURE 
Note:
Set the MLP capability with the factory shipment value (06H 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 address110 H  
and 111 H
[1] Addresses (hexadecimal values) on setting the MLP capability.
The MLP capability 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 bit 1 and bit 2 in 
the lower-half 8 bit to “1” or “0”.
Accordingly, since the upper-half 8 bits are always “00H”, set only the lower-half 
8 bits (address 110H).
ADDRESS MLP CAPABILITY
110H  Lower-half 8 bits setting address (b0 to b7)
111H Upper-half 8 bits setting address (b8 to b15)
xi:

NETWORK CLASSIFICATION CAPABILITY SETTING
TERMINAL CAPABILITY RELATED
SUMMARY: 
When communicating with a network having its basic line capacity restricted to 
56 kb/s such as ACCUNET in North America, set “56 kb/s (restricted)” to ON.  If 
all the networks are in 64 kb/s, set it to OFF.
STEP PROCEDURE 
1 Enter the following command.
SSPR__ n1 =  x1 __n2 = x2 __ … ni = xi … ¿
ni:
System parameter address112 H  
and 113H
[1] Addresses (Hexadecimal values) in setting the network classification capability.
The network classification capability 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 bit 
1 in the lower-half 8 bits to “1” or “0”.  Accordingly, since the upper-half 8 bits are 
always “00H”, be sure to set only the lower-half  8 bits (address 112H).

MBE CAPABILITY SETTING
TERMINAL CAPABILITY RELATED
SUMMARY:
MCU 5000A uses MBE to expand NEC original function.
STEP PROCEDURE 
Note:
Use the MBE capability with the factory shipment value (01H 00H
) as a general rule.  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 address116 H  
and 117H
[1] Addresses (hexadecimal values) on setting the MBE capability.
The MBE capability 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 bit 0 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 116H).
