3.3.3 Programming the QuadScan Elite's Address
With RS-422, there may be as many as 8 QuadScan Elite's operating within a system. In order to provide a control
mechanism to differentiate each QuadScan Elite, each QuadScan Elite is assigned a unique address using the Front
Panel.
Programming the address is a simple procedure.
Front Panel Display must say QUADSCAN
1.
. Press the right arrow button once (RS-232/422 Address Menu)
2.
. Pressing either the up or down arrow buttons will change the address itself.
3.
. Press the Plus button to lock in the address
4.
. Auto Save feature will automatically save this address.
The address circuitry is active even when you are using the RS-232 link (which does not permit multiple QuadScan
Elite's or other devices to be connected in a multiple unit configuration).
NOTE:
•
It is possible to change the RS-232 address to be anything between 0 and 7. The standard address is 0.
•
Performing either a MODE or FULL RESET will not change the RS-232/422 address for any of the QuadScan
Elite's.
3.3.4
Sending Communications Commands to the QuadScan Elite
The serial port of the QuadScan Elite accepts serial data at 9600 baud, 8data bits, no parity bit, 1 stop bit. It is essential
that the serial communications device that delivers commands to the QuadScan Elite be set up in this fashion.
Additionally, a 10ms delay must be inserted between each character sent to allow processing time. Programs like Hyper
Terminal allows you to add the delay time. If you are using the Panja, Phast, or AMX controllers you will need to check
their users manual to determine how to add the 10ms delay.
NOTE:
The QuadScan Elite does not have bi-directional communication capability. What this means is that there is no direct
feedback via the RS-232/422 control as to what commands or functions are being executed on the QuadScan Elite. What
will happen is that as each function is sent via the RS-232/422 control, the QuadScan Elite's Front Panel Display will
show what function register is being changed along with the range (if sent) for that register.
The QuadScan Elite accepts 8 bit characters as commands. The commands to enable or disable the QuadScan Elite's
RS-232/422 are received as strings of ASCII characters. For the purposes of this manual, all ASCII characters will be
referred to with the hexadecimal numbering sequence (i. e. the minimum value of a byte is 00, the maximum value of a
byte is FF, the value of an upper case A is 0x41).
The Command sequence for communicating with the QuadScan Elite is as follows:
1.
Send the Activation Command
2.
Send the QuadScan Elite Control Commands
3.
Send the De-Activation Command
