The SIMATRIX NEO V2 allows the connection of 8 keyboards via CL/TTY
interfaces. The factory transfer setting of 2k4, 8E1 can be changed using the
programming software.

A maximum of 8 keyboards can be connected to the keyboard interfaces. Each
keyboard may draw a maximum of 200mA from the SIMATRIX NEO. The total
current draw must not exceed 400mA. This means that the SIMATRIX NEO V2 can
provide a current supply for a maximum of 4 SUT48s, CKA4810s or CKA3210s.
The current supply is protected by an internal self-resetting fuse. Each interface
can provide a maximum of 200 mA.
Any additional keyboards require the use of an external 12 V DC, plug-in power
supply (e.g. 2GF1800-8BE).
The NEO is capable of providing the supply up to a maximum distance of 50 m.
This requires a 6-core cable.
If an external power supply is used, the maximum permissible distance is 1.2 km
with 0.8 mm wire diameter. In that case pins 2 and 3 and pins 4 and 5 have to be
connected via one pair of wires each. Pins 1 and 6 must not be connected.
The "COM2/3" and "COM4" connectors are RS232 interfaces. The Y cable
supplied with the device must be used to connect to the COM2 and COM3
interfaces.
