Sending a Location/Address
The RLPC use a Location to identify where the device recorded its
data. The device address identifies the communications address of the
device. For the MR protocol, Location and Device Address are the
same value, LOC.
The first step in sending commands to a counter is to wake it by
sending its Location/Address. Once a unit has been selected, it remains
selected until a different Location/Address is sent.
The Location/Address is configured either through the DIP Switches or
through the software command
WL
depending on the configuration of
DIP Switches 7 and 8. See Table 4-2 on page 4-2.
Whether configuring a device address using the DIP switches or
through the
WL
command, that address must be used in Hyper terminal
or ProComm to communicate with that specific device when there are
multiple devices on a chain.
Note:
For laptop
computers, enable
NUMLOCK to access the
numeric keypad. Different
laptop models access
NUMLOCK in different
ways. Please consult
laptop manual for more
information.
Example:
Press/Hold ALT Key, then type 0128
{Location/Address 0}
The subsequent commands will apply to the device at Location/
Address 0.
All device select entries lie in the range of 0128 - 0191 which
correspond to Location Address 0 -63. Leading zeros must be entered.
