For current converters that are not active current sources, a current
source may be selected from the board by placing a jumper (for example,
a jumper on J7-A for the transmit signal) at J-7. This will provide a
current loop source of approximately 20 ma. for a maximum distance of

For communications that must occur a longer
distance than 100 feet, (but less than 1000 feet) the
current loop may be used instead of the RS 232
signals. The three loops supported are the busy
loop, the receive loop and the transmit loop.
Because TEC printer messages are relatively
short, a busy signal control is not usually required.
The busy loop is only active for systems that have a
transaction buffer (See Pg. 52). The ground and the
transmit loop are the only signals usually required for
a printer. Information may be transmitted to the
printer at rates from 300 baud to 9600 baud. Many
serial printers that support current loop, restrict the
speed to 1200 baud. Baud rate may be selected
from the communications setup menu (see Pg. 52).

requires a jumper as shown below.
