3. Check communication with the missing unit:
o If the system has a wired connection, refer to Channel/Signal Tests, page 34.
o If the system has an RF link, refer to page 33.
4. Check Baud Rate (refer to the relevant section in Network Connection, page 26) on both sides
if using 232/485 communication card.
