Overview

3 Overview
The TP-185 is a high performance, 8 channel VGA/UXGA
1
In particular, the TP-185, 8 Channel UXGA/Audio/RS-232 to CAT 5 Transmitter
features:
, audio and RS-232 to CAT 5
transmitter for high resolution video, stereo unbalanced audio and RS-232 signals. The
CAT 5 outputs can be connected to an y Kram er compatible TP receiver, for example, the
TP-126. The TP-185 can also route data from the RS-232 or RS-485 port to any of t he
CAT 5 outputs.
• Eight UXGA video inputs
• Eight stereo unbalanced audio inputs on 3.5mm mini jacks
• Eight RJ-45 STP/UTP outputs
• Transmission of RS232/RS-485 data from one input to any or all of the eight
CAT 5 outputs, and one reply from the selected output
The TP-185 can d iff eren tiat e betw een RS -232/RS-485 commands that control the unit
itself and commands that are destined for end-user equipment (see
Section 7.1.5.2
The TP-185 is dependable, rugged, and fits into one vertical space (1U) of a standard
19” professional rack.
).
To achieve the best performance:
• Use only good quality connection cables
2
• Do not secure the cables in tight bundles or roll the slack int o tight coils
to avoid interference, deterioration
in signal quality due to poor matching, and e levated no ise level s (often
associated with low quality cables)
• Avoid interference from neighboring electrical appliances that may adversely
influence signal qualit y, a nd position your Kramer TP-185 away from
moisture , excessive sunlight and dust
3.1 Shielded Twisted Pair/Unshielded Twisted Pair
We recommend that you use Shielded Twisted Pair (STP) cable. There are different levels
of STP cable available, and we advise you to use the best quality STP cable that you can
afford. Our non-skew-free cabl e, Kram er BC-STP is intended for analog signals where
skewing is not an issue. For cases where there is skewing, our UTP skew-free cabl e Kram er
BC-XTP, may be used. Bear in mind though, that we advise using STP cables where
possibl e, s in ce th e com plian ce t o el ect rom agnet ic int erf eren ce was tested using those
cables. Although Unshielded Twisted Pair (UTP) cable might be preferred for long range
applications, the UTP cable should be installed far away from electric cables, motors and so
on, which are prone to create electrical interference.
However, since the use of UTP cable might cause inconformity to electromagnetic
standards, Kramer does not commit to meeting the standard with UTP cable.

7 Setting the DIP-switches on the TP-185
The DIP-switches on the TP-185 p erfor m the following functions:
• RS-485 termination
• Reply enable/disable
• Reply machine number
• Baud rate
• Hardware/software mode
Moving a D IP-switch down turns the switch on, moving it up turns the switch off.
Note: Changing any DIP-switch requires that you cycle power on the TP-185
7.1.1 Setting the RS-485 Bus Termination
The DIP-switch sets the RS-485 bus ter mination. Only the first and last phys ic a l
device on the RS-485 bus must be terminated, all other devices must be
un-terminated.
Figure 4: TP-185 DIP-switch RS-485 Termination
When DIP-switch 1 is:
• OFF, the unit is un-terminated (default)
• ON, the unit is terminated
Note: DIP-switch 2 is not used.
7.1.2 Enabling and Disabling the Reply Feature
DIP-switch 1 enables and disables the Reply feature.

When DIP-switch 1 is:
• Up, Reply is disabled (default)
• Down (ON), Reply is enabled
7.1.3 Setting the Reply Source or Machine Number
DIP-switches 2, 3 and 4 set either the reply source (in Hardware mode Table 2) or
machine number (in Software mode
Table 3).

7.1.4 Setting the RS-232/RS-485 Baud Rate DIP-switches
DIP-switches 5, 6 and 7 set the serial port baud rate in both Hardware and Software
modes according to
Table 4.
Note: In a multiple device configuration, all devices must b e set to the same baud
rate.

7.1.5 Selecting Hardware/Software Mode
DIP-switch 8 sets the operating mode to either Hardware or Software mode.
Figure 8: TP-185 Baud Rate Hardware/Software DIP-switch
When the DIP-switch is:
• OFF, the unit is set to Hardware mode (default)
• ON, the unit is set to Software mode
7.1.5.1 Hardware Mode
In Hardware mode, the:
• RS-232 data is passed from any input to all outputs
• TP-185 routes the reply from the output port defined by the DIP-switches 2, 3
and 4 (see
Section 7.1.2). For reliable operation, only one port can be defined
Page 16
Wiring the Twisted Pair RJ-45 Connectors

7.1.5.2 Software Mode
In Software mode, the TP-185 routes the data and reply based on the Protocol 2000
commands received from the PC or other device connected to any of the inputs.
The following example illustrates a typical command sequence. The destination and
return pa ths to and from the end-user device are set (TP-185 control commands),
then an end-user device command is sent to the defined destination. The TP-185
differentiates between the two types of commands and acts accordingly.
The sequence is as follows:
1. Set destination path for command
2. Set return path
3. Send end -user command sequence

N5…N0 – “INSTRUCTION”
The function that is to be performed by the switcher(s) is defined by the INSTRUCTION (6 bits). Similarly, if a function is performed
via the machine’s keyboard, then these bi ts are set with the INSTRUCTION NO., which was performed. The instruction codes are
defined according to the table below (INSTRUCTION NO. is the value to be set for N5…N0).

When switching (ie. instruction codes 1 and 2), the INPUT (7 bits) is set as the input nu mber which is to be switched. Similarly, if
switching is done via the machine’s front-panel, then these bits are set with the INPUT NUMBER which was switched. For other
operations, these bits are defined according to the table.

When switchin g (ie. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched. Similarly, if

When several machines are controlled from a single serial port, they
are usually configured together with each machine having an individual machine number. If the OVR bit is set, then all machine

NOTES on
Table 9:
NOTE 1 – When the PC sends this command, if the instruction is valid the unit replies by sending the PC the same 4 bytes that it was
sent (except for the first byte where the Destination bit is set high).
NOTE 2 – If O6 = 0 (Tx) – This command defines/reads the definition of the output # (1, 2 or3) to pass the RS-232/Direct command
from any input. In this case the instruction does not modify previously set output numbers, allowing the setting of multiple outputs for
the Direct command. If O6 = 1 (Rx), the command defines/reads the definition of the output # (1, 2 or 3) to pass the reply from the
output to inputs. In this case, the instruction resets a previously set output number, preventing the setting of multiple outputs for the
reply.
NOTE 3 – The reply to this command is as follows: The same command and outpu t codes as were sent are returned, and the input is
assigned the value of the parameter that was read. The reply is per the definitions in command 44.
NOTE 4 – At initial power-on or on reception of command 44 or 45, any received bytes are analyzed to see whether it is a command 44
or 45. If not, it is transmitted to the output based on the existing setup. If the analyzed bytes are a command 44 or 45, the unit waits for
the other 3 bytes and interprets them as a Protocol 2000 command. The command is executed if relevant to this machine number or
discarded if not.
NOTE 5 – This command works only when the unit is configured for Software mode.
