4 Protocol description
4 Protocol description
This chapter lists all commands supported by the adapter protocol. You can send the commands via the
COM port (e.g. using a terminal program).
The protocol is based on the specification CiA 309: Access from other networks - Part 3: ASCII mapping.
All commands are confirmed. You may start each command with a sequence number (UNSIGNED32), which
is then included in the response.
Example
// Request: Get name info, sequence=[1234]
[1234] info name
// Response: product name
[1234] name: ZK-USB-CAN-1
The token [net] is allowed to follow the [sequence] due to compatibility reasons, but it is ignored by the
adapter.
