Signal
name Signal direction Function
1 FG — Frame ground
2 TXD Output Transmit data
3 RXD Input Receive data
4 RTS Output DIP SW 2-2 OFF: Same as DTR signal (pin 20)
DIP SW 2-2 ON: Logical product of DTR signals of DM-D and TM (If both are
SPACE, the printer can receive data (SPACE).)
6 DSR Input This signal indicates whether the host computer can receive data.
SPACE indicates that the host computer can receive data, and MARK
indicates that the host computer cannot receive data.
When DTR/DSR control is selected, the printer transmits data after confirming
this signal (except when transmitting data by
DLE EOT
,
GS a
, or
FS ( e
).
When XON/XOFF control is selected, the printer does not check this signal.
Changing the DIP switch setting enables this signal to be used as a reset
signal for the printer. (See Chapter 1, “DIP Switches.”)
The printer is reset when the signal remains MARK for 1 ms or more.
7 SG — Signal ground
20 DTR Output 1) When DTR/DSR control is selected, this signal indicates whether the printer
is busy. SPACE indicates that the printer is ready to receive data, and
MARK indicates that the printer is busy. The busy condition can be
changed by using DIP SW 2-1 as follows:
DIP SW 2-1 status
Printer status ON OFF
1. During the period from when the power is
turned on (including resetting using the
interface) to when the printer is ready to
receive data.
