Reader/Writer Setting
Section 4-1
4-3
1) Communications type setting for COM1 port
Set whether COM1 will be used as RS-232C or RS-485
by using the communications type setting command (CT) (refer to No. 4 in
5-6-8 of Section 5).

2) Node No. setting
If more than one Reader/Writer is connected to a single host, each
Reader/Writer needs an ID number so that the host can discriminate one
Reader/Writer from another. Such an ID number is called node number. Each
Reader/Writer must be assigned a unique node number. Each command or
response includes the node number of the Reader/Writer. Communications
will not be possible if the node number is wrong.
The setting can be saved by executing the setting write command.
Use the node number setting command (NM) to set a node number (refer to
No. 1 in 5-6-6 of Section 5).

Note
Communications through COM2 are possible regardless of the node number
setting.
3) Terminal resistance setting
This setting is necessary when COM1 is used as RS-485.
If more than one Reader/Writer is connected to a single host, terminal re-
sistance must be turned on for both the host and the Reader/Writer con-
nected to either end of the host in order to ensure stable operation. The set-
ting can be saved by executing the setting write command.
Use the terminal resistance setting command (TM) to set the terminal resis-
tance (refer to No. 2 in 5-6-11 of Section 5).

4-1-2 Chip Operating Mode Setting
This Reader/Writer consists of 2 types of operating modes (hereinafter called
“operating mode”) in accordance with a type of the Tag (an incorporated IC
chip). You have to set either of the operating modes in accordance with the
Tag you choose.
Execute the operating mode switch setting command (TY) (refer to 5-6-15 of
Section 5).
