CONNECTING THE DEVICES
1. Connect the RD558 programming keyboard to the keyboard port on the rear of the
HMXAT200 control computer using the supplied adapter.
2. Connect the subracks to the RS-232 serial data ports on the rear of the HMXAT200.
Note:
The port number must match the subrack address number;
i.e. subrack address 1 to port 1, subrack address 2 to port 2, etc.
3. Connect each CCTV Control Keyboard (HEGS5300 or ULTRAKey) to an
RS-232 serial data port on the rear of the HMXAT200 System Controller,
beginning with keyboard number 1 connected to port 4, keyboard number 2
connected to port 5 etc.
Note:
The HEGS5300 and ULTRAKey keyboards are supplied with a 6-foot coiled
cable. It is strongly recommended that a twisted pair data cable be used from
the RJ11 Termination Box when long cable lengths are required to eliminate any
data problems. Keyboard cables may be extended up to 50 feet from the
HMXAT200. Keyboards greater than 50 feet from the HMXAT200 will require
external PTE102 RS232 line drivers. Refer to section 3.1 for specifications and
connections for the PTE102 Line Driver.
