NOTE:
Only set the DNS address if the server connection is fast and
reliable. Delays in DNS server access can negatively impact the opera-
tion of the IOC.
f ) Root password
Type in the new root password. The password must 5
to 8 characters in length. Please use the standard rules for selecting a
strong password (Not based on a dictionary word, a mix of upper and
lower-case characters and numbers).
g) Device name
This device name is the second part of the EPICS process
variable (PV). All PV names start with
IGPF:X:
, where
X
is the device
name. As delivered the iGp-5120F defaults to device name
TEST
pro-
ducing PVs of the form
IGPF:TEST:DELAY
. If multiple iGp-5120F units
are to be deployed they must be assigned differing device names. For
example, one could use device names
X
,
Y
,
Z
for horizontal, vertical,
and longitudinal feedback channels.
NOTE:
If the setup program is executed remotely and the network address is
changed, the
ssh
connection will hang at the end of the process. To connect
to the IOC, close the existing
ssh
session and start the new connection at
the newly assigned IOC IP address.

4.1
Utilities
The IOC includes several utilities designed to communicate to the iGp-5120F
directly, without using the EPICS softIOC software. These utilites allow the
user to access individual FPGA registers and memory locations. For register
descriptions and address map see Sec. 9. All of the utilities below will accept
addresses and data in decimal, hex, if preceded by
0x
, and octal, if the value
starts from
0
. For example, value 12 can be specified as
12
,
0xc
,
014
. In
order for these utilities to gain access to the FPGA interface the IOC process
must be terminated. To terminate the IOC execute:
[root@IOC ~]# pkill st.cmd
Here is a short description of the available commands:
usbr <addr>
Read a single register or memory location.
