GETC Cable Modifications
Use the following procedures to modify and reconnect
cables in the CNI GETC. Be sure to follow the correct
procedures. Instructions titled MASTR II or IIe are for CNI
GETC’s installed in MASTR II or MASTR IIe repeaters,
instructions titled MASTR III are for CNI GETC’s installed
in MASTR III repeaters only.
MASTR II & IIe
The following procedure provides instructions for
modifying the cables when the CNI GETC (option
STCP3Z) is used with a MASTR II or IIe repeater.
Materials for the modification are provided as part of the
Hardware Kit 344A3845G1.
1. Mount the Terminal block, 19C301087P10, on the
back of the GETC Shelf using the four (4) screws,
N80P13007B6, and two (2) nuts, 7160508P2
provided. Refer to Figure 5.
2. Disconnect the two (2) pairs of twisted wire
connected to P26-6, P26-7, P26 8 and P26-9 (part
of cable harness 19C320811G15/G16) from the
Backplane (19D417214) TB1201-18, -17, 11, and
10 or from the Control Panel (19B234871) or MIIe
Backplane (19D902459) TB1201-5, -2, -3, and -4
respectively.
3. Connect the pair from P26-8 and P26-9 to the
terminal block terminals 1 and 2 respectively. This
is the GETC Transmit Data pair, see Figure 6.
4. Connect the pair from P26-6 and P26-7 to the
terminal block terminals 3 and 4 respectively. This is the
GETC Receive Data pair.
5. Connect the harness assembly (19C320811) plug
P26 to the GETC Logic Board connector J6.
6. Connect the harness assembly (19C320811) plug
P27 to the GETC Logic Board connector J7.
7. Connect the harness assembly (19C320811) plug
P10 to the GETC Logic Board connector J10.
8. Connect the harness assembly (19C336863) plug
P8 to the GETC Logic Board connector J8.
9. Connect the harness assembly (part of 19C320811
and 19C336863) plug P19 to the GETC Logic
Board connector J19.
10. Connect the Regulator Board harness assembly
(A2W1) plug P1 to the GETC Logic Board
connector J27.
MASTR III
The following procedure provides instructions for
modifying the cables when the CNI GETC is used with a
MASTR III repeater. Materials for the modification are
provided as part of the MIII option SXCP5T.
1. Route the header (P26) on the Harness
19C337792P1 through the terminal block hole and
mount the terminal block to the back of the GETC
Shelf using the four (4) screws, N80P13007B6,
and two (2) nuts, 7160508P2 provided. Refer to
Figure 5.

Modification of the GETC for use with MASTR II
(IIe) and MASTR III repeaters differ. Use the
procedure applicable to the type of repeater associated
with the CNI GETC.
NOTE
On MASTR IIe stations only, using wire harness
19C320811G16. Cut the solid white jumpers
connected from P27-14 to P27-15 and from P27-6 to
P27-16.
