be selected using DIP switch sections 2 through 4. The
serial printer port can be turned off and on using DIP switch
section 5. The proper handshaking protocol for your printer
can be selected using DIP switch section 6. The IAM can
use both hardware and software handshaking, or just
software handshaking. The standard ELI option does not
provide a cable for this connection, but pin-out information
is shown in Figure 39.

Connecting a serial printer can sometimes entail some
trial and error to get things set up properly. If you need to
change any of the DIP switch settings, be sure to do a soft
reset on the IAM (the IAM will only look at the DIP switch
settings as part of the reset sequence).
change any of the DIP switch settings, be sure to do a soft
reset on the IAM (the IAM will only look at the DIP switch
settings as part of the reset sequence).
A soft reset is accomplished by pushing the RESET
button on the front panel two times. If the time between the
two pushes is too short or too long, the reset will be aborted.
The two pushes should be about 1/2 second apart. When the
two pushes of the Reset button are spaced correctly, the
front panel LEDs will all flash simultaneously as the IAM
resets.

13. IAM DIP SWITCH SETTINGS
The 13th step to install the ELI option applies only if
an IAM was supplied. Set the sections of the DIP switch on
the front of the IAM unit as needed. Figure 40 shows the
layout of the DIP switch sections and the function of each.

The position of each DIP switch section (except switch
section 5 which controls data to the printer) is read only
when the unit is reset. This means that changing the position
of any of the other DIP switch sections will have no effect
until the unit is reset or power-cycled.

14. GETC MODIFICATION
The 14th step needed to install the ELI option applies
only to MASTR III repeaters. If a MASTR III repeater will
be connected to a GTI unit or the Master GTI, the associated
GETC must be modified. (This does not apply to MASTR
II or IIe EDACS repeaters.)

GETC must be modified. (This does not apply to MASTR
II or IIe EDACS repeaters.)
Remove power from the GETC shelf and pull out the
tray containing the circuit boards until you can reach the
connectors along the rear edge of the main circuit board.
Disconnect the connector going to J7 (third connector from
the right). Carefully extract pin 8, using a small screwdriver
or scribe to depress the tongue of the pin in the open slot in
the side of the connector while you pull gently on the wire
going to the pin. Tape the pin to the cable and reconnect the
connector to J7.
