or P - print command requested. Heading is not
stored in the Secure Memory Module.
To remove the heading, transmit H with no subcom-
mand.
H1 or H2 The ASCII characters supplied in the subcommand
(maximum of 20 characters) will be printed as a
heading and saved for each subsequent X - transmit
or P - print command requested.
To remove the heading, transmit H1 or H2 with no
subcommand.
N Adds the current net weight to the accumulated
total.
E A two ASCII digit hex number is transmitted with
this command to enable a relay to be under the con-
trol of it's set point value. The power-on default is all
relays enabled.
! This command is used to reset instrument communi-
cation. It is typically used when an error or unintelli-
gible response is received from the instrument and
should used sparingly. It is recommended that it not
be used during "normal" communication retries (i.e.
unintelligible response), but instead be used as a last
resort (no response after retries are exhausted).
Internally, it performs the same operations as done
on instrument power-up. Refer to the REL Sub-
Command under the X (Xmit) Serial Commands
Command Set.

Operating
Procedures Step 1. The BCD option is setup by first entering the Option Menu
and selecting the BCD menu. The menu display shows a com-
bination of GNTDP (G = gross, n = net, T = tare, D = display,
P = print). (See Chapter 5 for setup instructions)
Step 2. The user may select which data will be present at the output.
If the "P" or print flag is selected, the data will only change at
the output once the PRINT button is pressed or the remote
functions print has been activated. Otherwise, the output will
be continuous.
Step 3. You can trigger the output by any of the following methods:
• By pressing the PRINT button.
• By sending a command over the serial port.
