- Page 3 On the Network the ZX-GPI is seen as a ZX-R2 Remote Controller so also requires a unique Channel ID and Sub ID. The Sub ID allows up to three ZX-GPI and/or ZX-R1 or remote controllers R2 to control the same Channel.
- Page 4 Figure 1.2: ZX-GPI Block diagram. CONNECTING THE ZX-GPI The ZX-GPI is connected to the Network using CAT 5, Ethernet cables fitted with RJ45 connectors, wired pin to pin. Two RJ45 sockets are provided on the ZX-GPI to allow easy daisy chaining.
- Page 5 Self powered through the Network. An external DC adapter connected to the NETWORK POWER jack. This may be necessary if the ZX-GPI is sited a long distance from the ZX135 or there are a large number of peripherals on the Network. See Section 7 and 8 for further details.
- Page 6 Value Sub ID Reserved for ZX-MR1 Master Controller So in the two examples shown in Figure 5.2 with Channel 5 selected, two ZX-GPI (ZX-R1 or ZX-R2 Remote controller) can control Channel 5. Please note: Sub ID '0' i.e. both switches in the OFF position, is reserved for the ZX-MR1 Master Controller, so cannot be used for the ZX-GPI.
- Page 7 A single switch (or voltage) can be used to change inputs on the ZX135. Link two of the Source change inputs on the ZX-GPI, e.g. GPI 1 and GPI 3, and reverse the polarity on one of these. Now when the control switch or voltage is operated the source on the ZX135 is changed between Input 1 and 3.
- Page 8 Figure 5.3: Link position and schematic for Switch mode. Voltage mode: In Voltage mode an external normally ON or normally OFF (depending on the setting of the Input Polarity switch) voltage is used to operate the GPI inputs. The external control voltage is connected between pins 2 and 3 and must be in the range 5V to 30V - see Section 8.0.
- Page 9 Internal: Power for the external switches is supplied by the ZX-GPI via a 1k0 resistor. External: Power for the external switches is supplied by the power supply connected to the POWER EXT socket. Each switch feed has a series 1k0 resistor -see figure 5.3.

Page 10: Dc Power Supply
9V to 12V DC, unregulated, 0.5A to 1A (depending on number of peripheral devices). DO NOT EXCEED 12V DC FOR NETWORK POWER AS THIS WILL CAUSE THE ZX-GPI AND OTHER PERIPHERALS TO OVERHEAT. Power Ext: This connector is used to supply power to the external contacts in Switch mode and is electrically separate from Network Power and ground.
