7.1.2 Note
1. For electrical specification
Electric specification of the communication port on FM-8800S/D side for updating a
program, is RS-422. Communication speed is 57.6 kbps.
Provide the RS-422 level converter with the specification more than 57.6 kbps. The
level converter (IC-485SN) for updating FA-100 is available.
2. If the serial port on the PC is anything other than [COM-1], update the batch file or
change the specified COM port to [COM-1] on the PC.
3. Where to connect PC varies with a program to be updated.

Updating via
Transceiver unit
NOTE: Even if some Remote Handsets are connected, Remote Handset ID is automatically
recognized and updated from the lowest ID number. See page 4-6 for details.
4. “Port setting” for the serial port on the PC is unnecessary. When updating it , it is
automatically set from the UppgNT.exe.
- At the time of booting up the program: 9600 bps
- PC and Transceiver unit are communicated for updating: 57.6 kbps
- Communicates among Transceiver unit, Remote Handset and DMC I/F: 38.4 kbps
Then, Remote Handset and DMC I/F program are temporarily downloaded into the
memory of Transceiver unit and loaded respectively. The main program is directly
loaded in CPU(H8S) of Transceiver unit. The protocols are as below.
- Format - Data bit: 8 - Stop bit: 1
- Parity bit: None
- Flow control - None
