CONNECTIONS
Camera Inputs
For each camera input there are a pair of BNC sockets, one for the camera input, the other for a looped through
output. If you connect to both BNC sockets, your expander unit automatically removes the 75 ohm termination
resistor. If you use the loop through facility make sure that your application (e.g. a monitor or VCR) provides 75
ohm termination at the end of the line.
Connect up to 16 camera inputs. You can use either the upper or the lower sockets. Connect your loop through
outputs to the through or spare BNC socket in each pair. If you have less than 16 cameras, you can disable
individual camera inputs in the menu system.
Monitors
Monitors C, D and E connect to the relevant 75 ohm BNC connectors. If you are connecting directly from the
expander unit to the monitor then select the 75 ohm impedance setting on your monitor. Note that when the 32
way expander unit is used, Monitors C, D and E attach directly to the BNC connectors provided on the
expander unit and not the multiplexer. This is to ensure that the monitor signals are correctly terminated.
Alarm Inputs
Provision for alarm inputs is by means of a 25 way D-type connector. Wire the connector as shown in Figure 3.
Do not attempt to wire directly to the socket on the back-panel.
Fig 3. 25 way D-type Connector Numbering
Figure 3 above shows the connector, looking towards the rear panel. The numbers are labelled on the connector
itself.
Pin Numbers Connections
1 to 16 Alarm Inputs 17 to 32
18, 19 Alarm Input Ground
Each alarm input line can be triggered by the relay contact from a device such as a pressure-pad, a passive
infrared detector, a smoke detector etc. (refer to the instructions provided with the device). You can configure the
alarm inputs to be Normally Open (N/O) or Normally Closed (N/C) via the menu system. Normally open and
normally closed configurations are shown in Figure 4. The alarms are disabled while the menu system is active.

CONNECTIONS
Power
The ZMX+EXP32 is supplied with a 12V DC class 2 output, auto-ranging: 110/230V AC (+6%, -10%) 50Hz,
external power supply. Do not use any other power supply. Do not connect the power until you have read the
section, Powering Up your ZMX+EXP32 below.
Attach a suitable 3 pin plug following the wiring instructions on the label attached to the mains lead.
Note: The manufacturer accepts no responsibility for any damage caused by the use of any other power supply.
Plug the mini power connector from the 12V DC power supply into the socket marked 12V DC on the rear of your
expander unit. Adjacent to the socket is a cable anchor. Use a small cable tie to attach the power supply cord to
the cable anchor. This helps to prevent inadvertent power disconnection which may be caused by the power
cable being pulled.
Expander cable
The expander unit and multiplexer are connected together by means of a special cable. Attach the cable and
ensure the connector screws are tightened to prevent the cable being pulled out
.
POWERING UP YOUR ZMX+EXP32
Your expander unit must be powered up before the multiplexer. This is because the multiplexer polls the expander
unit as part of its power-up sequence. After all the relevant connections have been made between the expander
unit and multiplexer, perform the following sequence:
1. Disconnect the power from your multiplexer.
2. Connect the power to your expander unit
3. Reconnect the power to your multiplexer
SETTING THE MULITPLEXER TO 32 WAY
Your multiplexer must be set to 32 way in order to gain access to various menu items for the expander unit. This
is done as follows:
1. Enter the menu system of your ZMX+CT16M4 multiplexer.
2. Use the left/right arrow keys to select Main.
3. Use the up/down arrow keys to select Camera Setup and press the enter key.
4. Use the up/dwon arrow keys to select Camera Selection 16/32 and press enter.
5. In the Number of Cameras field, use the left/right arrow keys to select 32.
6. Use the up/down arrow keys to select OK and press enter.
NOTE: After selecting OK, the multiplexer will reset itself. Any parameters that were previously set up in
the multiplexer will be lost. The multiplexer must be powered down and back on again in order for the
new settings to take effect.
