4.6.0 Communicating with the PDL-100A over Ethernet TCP/IP.
TCP/IP Protocol using Winsock sends data packets to individual IP addresses
over a unique and pre-specified port. The PDL-100A supports fixed (static) and
dynamic IP addresses and the Winsock interface. Network Addresses including
IP address, Gateway IP, Netmask, DHCP, and Port Number can be specified or
changed by sending commands to the PDL-100A using the GPIB, TCP/IP, or RS-
232 interfaces.
To change the network addresses using a command interface,
see Section 5.0
Command Commands for NET, NET? and NETM? Commands.
To change the network addresses using the MT-100A Microterminal,
see Section
4.3.4 SETUP Menu – Network Addresses.
4.6.1 Default Network Addresses
IP Address
192.168.100.8
Gateway Address
192.168.100.1
Netmask
255.255.0.0
DHCP
OFF
Port Number
1234
These are the default network addresses at time of manufacture and are stored
internally in non-volatile storage. If you are unable to communicate with the
PDL-100A over Ethernet after changing a network address (no MT-100A
Microterminal or GPIB communication available) and want to restore the default
address settings, set the GPIB address switches to Zero (all OFF) and power-cycle
(turn OFF then ON) the PDL-100A System Unit. The default address will take
effect.
4.6.1.1 Programming over the Ethernet TCP/IP
When programming the instrument over the Ethernet TCP/IP interface,
characters are
NOT
echoed (sent from the PDL-100A) back to the PC
when sending the command string. For example, from your application
program if you send the character string:
*IDN?<CR><LF>
the PDL-100A will respond with:
Colby Instruments.PDL-100A-625.0PS-
05111020.V1.10<CR><LF>
