MCP Throughpass

Hi,

Can somebody help me and explain this (found in PM Offsets documentation) :

Suggestion:
V10 MINS
V11 BARO
V12 Copilot MINS
V13 Copilot BARO
V101002 (increments MINS by 2 units)
V110004 (decrements BARO by 4 units) V11 [baro] 0 [dec] 004 [4 units]
Send offset and value to write in UIPC...
E0 [offset] [numbytes] [value] (value can be anything after the 7th byte, with or without leading zeroes
E00BC081234.5 writes 1234.5 in 0XBC0 8 bytes (=double)
E004F42005 writes 5 into 0x4F4 (i.e. E0 04F4 2 005)
E004F422 writes 5 into 0x4F4

This option seems to be very powerfull but I do not understant where to write these values. I tried to program an encoder for the CPT BARO setting but when I send the value 111004 or 110004 into 04F4 (MCP Throughpass) nothing happens. Do I need to send these commands to another offset ? Here is a piece of my SIOC program :

Var 4036, name CPT_BARO_ENC, Link IOCARD_ENCODER, Device 1, Input 40, Aceleration 3, Type 2 // CPT BARO Encoder
{
L0 = &CPT_BARO_ENC
IF L0 > 0
{
&MCP_THROUGH = 111004
&MCP_THROUGH = DELAY 0 ,25
}
IF L0 < 0
{
&MCP_THROUGH = 110004
&MCP_THROUGH = DELAY 0 ,25
}
}

Please help me...
