Jumper Details
Jumper JP10 (4-Wire RCV Impedance)
This jumper selects the impedance of the 4-wire receive audio. There are three positions
for this jumper:
Position A = Sets impedance to 600 Ω
Position B = Sets impedance to 10 k
Ω
No jumper = Sets impedance to 10 k Ω
JP10 should be in the “A” position (600 Ω ) for the primary Model 6203. If there is a
secondary Model 6203, connected in parallel to the primary position, the JP10 in the
secondary should be in the “B” position (10 k
Ω ).
Jumper JP11 (IP/Serial Port Baud)
This jumper selects the serial port baud rate for connector J6. The default condition for
this jumper is “
9600 ”.
9600 = Port runs at 9600 baud
4800 = Port runs at 4800 baud
2400 = Port runs at 2400 baud
Jumper JP12 (IP/Serial Port Rx Data)
This jumper selects the pin on connector J6 from which serial received data will be taken.
There are three positions for this jumper:
Position A = Receive Data is taken from J6 Pin 2 (normal
connection)(default)
Position B = Receive Data is taken from J6 Pin 4 (Zetron
connection)
No jumper = No receive data (Do Not Disturb) and should be
avoided if possible.
This jumper should be in the position that matches the serial data source on the mating
connector. The Model 6203 will always use Position A. An alternate connection is
supplied to support some older Zetron equipment which uses pin 4 of the serial cable for
received data.
Jumper JP13 (Serial Port Received Data Connection)
This jumper selects the pin on connector J1 from which serial received data will be taken.
There are three positions for this jumper:
Position A = Receive Data is taken from J1 Pin 2 (normal
connection)(default)
Position B = Receive Data is taken from J1 Pin 4 (Zetron
connection)
No jumper = No receive data (Do Not Disturb) and should be
avoided if possible.
