# wiz550 packing condition length

## Question

Asked by Sylvain papayou53 on 2018-02-18 in Serial-to-Ethernet & ConfigTool.

Hello,

I would like some information about the packing
condition (char delimiter) between 2 serial/ Ethernet network module.

Could you confirm, that the wiz120 module have only
one byte (in HEX) for packing condition while the wiz550 module have 4
bytes ?

Thanks.
