4.6CLONING (PROGRAMMING ONE TRANSCEIVER WITH ANOTHER)

One transceiver can be used to program another with identical data. Replication Cable, Part No. 597- 2002-200 is required to connect the transceivers together (see Table 1-1). The master (source) trans- ceiver must have the following Common screen (see Table 4-7) parameters programmed to perform cloning:

•Transmit Data Out = Enabled. If this parameter is not enabled, the transceiver does not go into the clone mode. The programming of this parameter does not affect the ability to receive data. Therefore, it can be in either mode in the slave (target) transceiver.

•Set Mode Access = Enabled. This must be pro- grammed to allow the Dealer Set mode to be accessed so that cloning can be enabled.

•Dealer Passcode. This six-digit code must be known to enable the Dealer Set mode.

Proceed as follows to program one transceiver with another:

1.Select the Dealer Set mode in the Master (source) transceiver by turning power on with the F1 and up key pressed.

2.The display then indicates “DEALR” which is the prompt to enter the six-digit Dealer Passcode. Enter

this code using the F1-F4 and down key. The numbers represented by each key are as follows. When the correct number is entered, “SETMODE is displayed. If six digits have been entered and this is not displayed, an incorrect number may have been entered. Repeat starting with step 1. Refer to Section 3.3.2 for more information.

Key	F1	F2	F3	F4



Number	0	1	2	3	4
Entered	5	6	7	8	9

3.Press the F4 key to select the clone mode. The display should indicate “CLONE”.
