Model 622x communications
For Delta, Pulse Delta, and Differential Conductance, the Model 622x uses two
interfaces for communications. It uses the RS-232 to communicate with the Model
2182/2182A, and it uses the GPIB or Ethernet (Model 6221 only) to communicate
with the PC.
Configure the Model 622x for communications as follows:
1.
RS-232
– On the Model 622x, press the
COMM
key and then select
RS-232
from the communications setup menu:
a.
Set the
BAUD
rate to
19.2K
.
b.
Set
FLOW CTRL
(flow control) to
NONE
.
c.
Press the
ENTER
key.
The Model 622x will reboot if RS-232 was not the previously selected
communications interface.For details on RS-232 configuration for the
Model 622x, see
.
2.
GPIB or Ethernet
– The GPIB or the Ethernet (Model 6221 only) must be
the selected interface to allow communications with the PC:
On the Model 622x, press the
COMM
key and then select
GPIB
or
ETHERNET
(6221 only) from the communications setup menu:
•
GPIB – Set the IEEE-488 address (0 to 30).
•
Ethernet (6221) – Set the IP, Gateway, Subnet, and DHCP.
After configuring the GPIB or Ethernet, press
ENTER
. The configured
communications interface will be selected and the Model 622x will reboot.
See
