Command List Entry Errors
Code Description
-40 Too few parameters
-41 Invalid enable code
-42 Internal address > maximum address
-43 Invalid node address (<0 or >255)

-47 ARP could not resolve MAC from IP (bad IP address, not part of a
network, invalid parameter to ARP routine).
-48 Error during ARP operation: the response to the ARP request did
not arrive to the module after a user-adjustable ARP Timeout.
Note: When the Client gets error -47 or -48, it uses the adjustable ARP Timeout parameter in the
configuration file to set an amount of time to wait before trying again to connect to this non-existent
server. This feature allows the Client to continue sending commands and polling other existing
servers, while waiting for the non-existent server to appear on the network.
