Connecting the MLA VC10 Plus to an IP Link control processor
Figure 8 also shows how to connect the MLA VC10 Plus to COM port 1 of the
IPL T SFI244. Connecting to other IP Link control processors is very similar.
1. Connect the Transmit (Tx) socket on the rear panel of the MLA VC10 Plus to the
Receive (Rx) socket of an IP Link control processor.
2. Connect the Receive (Rx) socket of the MLA VC10 Plus to the Transmit (Tx) socket of
an IP Link control processor.
3. Connect the ground (G) socket of the MLA VC10 Plus to the ground ( ) socket of the
IP Link control processor. If another device is using COM port 2 of the controller, it
may be necessary to splice the ground wires together.
Connections to a Third-party Control System
Third-party control systems issue SIS commands to the MLA VC10 Plus. For a list of SIS
commands, see the “
Command and Response Table for SIS Commands ” on page 33.
If the MLA VC10 Plus is to be connected to a third-party control device:
1. Connect the transmit socket (Tx) on the rear panel of the MLA VC10 Plus to the
receive socket of the control device.
2. Connect the receive socket (Rx) of the MLA VC10 Plus to the transmit socket of the
control device.
3. Connect the ground socket (G) of the MLA VC10 Plus to the ground socket on the
control device.
