1 Open a terminal from any computer in counting house and type the command:
->telnet hatsv4 2004
2 After connecting to that port and hitting the enter key, a prompt should pop up and we can set the EDTM pulser rate by the following command:
->r_pulser_Start(0,0xa100,0xc339)
The meaning of the arguments are explained below.
3 To quit from telnet, hold the "ctrl" key and hit "]". we should then see a prompt like "telnet>". Now type "q" to close the connection.
The EDTM pulse is now supplied by a synchronous pulser generator based on VME programmable logic. The generator has two synchronous outputs and the output rates are controlled by the second and third argument in the function r_pulser_Start() respectively. Currently the second output is used to feed the EDTM module and the first output is irrelevant. We shall set the first argument in function r_pulser_Start() to be 0 to set the rate of both outputs of the pulser generator.
The table showing the correspondence between the pulser rate and the hexadecimal words used in the r_pulser_Start() function can be found by typing the following command in a terminal opened on a computer in the counting house:
