AD8HR
UPGRADE
The AD8HR contains an internal flash memory. The software version can be upgraded from the HA REMOTE 1 terminal
by using dedicated software on a Windows PC.
A check is made for a system program in the flash memory when the power is turned on.
If the correct system program is found, then the start up runs as usual. If the flash memory contains no such program or
if there is a program error, then program boot mode is automatically triggered.
(1) Connections
Connect a serial port on the PC to the HA REMOTE 1 terminal on the AD8HR with the D-SUB 9-pin serial cross-cable.
Select the PC/RS422 selector switch to the PC side.
The version upgrade program can also be loaded into 2 or more AD8HR units connected as shown below. However,
device numbers are determined as the order of HA REMOTE 1 terminals connected near PC.
(The software can accommodate up to 4 units.)
