Sub-address (SUB/SID)
SUB Signal:
The SUB (sub-address) signal transmitted from the TX terminal contains a
confidential ID. A stored message can be printed using the SUB ID as a
confidential ID.
The SUB ID must contain four digits. The receiving terminal automatically
disconnects the line when any of the following conditions occur (error code 0-15):
• When the SUB ID is other than four digits
• When anything other than numbers is included in the ID
• When a confidential ID is not programmed in the RX terminal and when the
transmitted SUB ID is 0000
A stored message can be printed using the (normal) confidential ID stored in the
machine when the SUB ID sent from the transmitter is 0000.
SID Signal:
When transmitted together with the SUB signal, the SID programmed is an ID code
for the confidential ID stored override.
NOTE: SID reception is disabled for this machine.
This machine automatically disconnects the line when it receives a SID
signal.
