When Single Packet (Press ENTER) is selected, each time you press the ENTER

Parity. Use the left (◄) and right (►) arrow buttons to select between Automatic
and Manual parity. Automatic parity is an 8-bit mode, while Manual parity
allows 10-bits. If a 10-bit word is entered while in manual parity and the module
is later set to automatic parity, the correct 8 bits will be sent. The entire 10-bit
word is in system memory, though, so if the module is then reset to manual parity
the entire 10-bit word entered by the user will be transmitted.
DID. Press the ENTER button to edit the Data ID word. You can set the Data ID
from 0x00 to 0xFF (in 8-bit mode), or from 0x000 to 0x3FF (in 10-bit mode). Use
the left (◄) and right (►) arrow buttons to position the cursor, and then use the
up (▲) and down (▼) arrow buttons to set the number for that position. Press the
ENTER button to confirm the Data ID and exit Data ID editing.
SDID. Press the ENTER button to edit the Secondary ID word. You can set
the Secondary ID from 0x00 to 0xFF (in 8-bit mode), or from 0x000 to 0x3FF
(in 10-bit mode). Use the left (◄) and right (►) arrow buttons to position the
cursor, and then use the up (▲) and down (▼) arrow buttons to set the number
for that position. Press the ENTER button to confirm the Secondary ID and exit
Secondary ID editing.
DC. Press the ENTER button to edit the Data Count word, to show the number
of User Data Words to follow. You can set the Data Count from 0x00 to 0xFF
(in 8-bit mode), or from 0x000 to 0x3FF (in 10-bit mode). Use the left (◄) and
right (►) arrow buttons to position the cursor, and then use the up (▲) and down
(▼) arrow buttons to set the number for that position. Press the ENTER button to
confirm the Data Count and exit Data Count editing.
UDW. Use this menu item to set a User Data Word. Use the left (◄) and right
(►) arrow buttons to select the User Data Word you wish to edit, from word 000
through word 254, and then press the ENTER button to edit that User Data Word.
You can set the User Data Word from 0x00 to 0xFF (in 8-bit mode), or from
0x000 to 0x3FF (in 10-bit mode). Use the left (◄) and right (►) arrow buttons to
position the cursor, and then use the up (▲) and down (▼) arrow buttons to set
the number for that position. Press the ENTER button to confirm the User Data
Word and exit User Data Word editing for that word.
NOTE. To make this process easier, you can use the PC-based TG Setup
application. This application also allows you to import and export User Data
Words as CSV files.
