2.9 Connection of Peripherals
Pager
Only 1 paging device (user-supplied) can be connected to the Hybrid IP-PBX.
CAUTION
An External Paging Jack is an SELV port and should only be connected to an approved
SELV device.
PC/Printer (via RS-232C)
The Hybrid IP-PBX is equipped with an RS-232C interface. This interface provides
communication between the Hybrid IP-PBX and the user-supplied devices such as PC or line
printers. The RS-232C port is used for system programming, SMDR, diagnostics and external
system database storage (save/load) functions.
Note
Use an RS-232C cross cable for connection between the Hybrid IP-PBX and PC.
