channel that is currently assigned to a digital output.
U8
: Reads the current configuration settings for each channel configured in the unit. This command returns the
same information in as the
U9
: Read the Digital Inputs. This command will read the current state of the digital inputs. This function is
performed by reading each of the eight digital inputs, converting each input to a binary (high is
and converting that aggregate binary 8-bit number into a decimal number. The decimal number is then returned
as the response
U10
: Queries the installed memory option. This command will return the amount of memory installed (in
Kbytes). The possible responses are:
U11
: Queries all channels having programmed valid alarm setpoints. The response is

U13
: Queries the last scan read.
U14
: Queries the card type. Returns card ID for each card slot. Valid card IDs for use with NetScan are:
Note: This command can only be issued when all channels are in an unconfigured state. If any channel is
