The ResponseTimeoutSec key defines the time in seconds that must pass with no response from the device when responding from a SCPI command before an error is generated.

If this value is omitted then the default value is 60 seconds

An Example:

;*******************************************************************************
;The ICM MultiSwitch with 10 switches.
;*******************************************************************************
[ICM]
;The configuration type of this section
ConfigType = MultiSwitch
;The time to wait in seconds (this can be a fraction of a sec i.e. 0.5) for a TCP connection to the device
ConnectionTimeoutSec = 1.5
;The IP Address of this device as 'ddd.ddd.ddd.ddd'
IpAddress = 10.11.201.20
;The time to wait in seconds for a response to begin when communicating to the device via SCPI
ResponseTimeoutSec = 60
