RS 422: When connecting the unit to a computer
with RS 422, five connections are needed. These
connections are: Receive data A (+), Receive data
B (-), Transmit data A (+), Transmit data B (-) and
Ground. The connections should be made as
follows:
DB-9 CONNECTOR

Trans. data A(+) (pin 2)
Rec. data A(+)
Trans. data B(-) (pin 7)
Rec. data B(-)
Rec. data A(+) (pin 3)
Trans. data A(+)
Rec. data B(-) (pin 8)
Trans. data B(-)
Ground (pin 5)

RS 232: When connecting the unit to a computer
with RS 232 communication, only three connec-
tions are needed. These connections are: Receive
data, Transmit data and Ground. The connections
should be made as follows:
DB-9 CONNECTOR

PRINTER HOOKUP:
When connecting the unit to a printer, you must first
program the desired baud rate, parity and strobe list with
a computer. After the unit is
programmed it can be
connected to the printer. Connect the transmit
line(s) of the unit to the receive line(s) of the printer
and be sure that both devices have common
grounds. When the strobe line is triggered the unit
will transmit the selected strobe list which you had
previously programmed.

RS 232
1- Printer busy: 3 to 30 VDC level inhibits transmission.
2- Transmit A(+) (RS422); Transmit (RS232)
3- Receive A(+) (RS422); Receive (RS232)
4- Not Used
5- Ground
6- Strobe: 3 to 30 VDC positive edge starts transmossion.
7- Transmit B(-) (RS422 Only)
8- Receive B(-) (RS422 Only)
9- Not Used
